A complete denture can be either “conventional” or “immediate.”  A conventional type is made after the teeth have been removed and the gum tissue has healed (usually takes 4 to 6 weeks).  During this time, the patient will go without teeth.  Immediate dentures are made in advance and immediately placed after the teeth are removed, thus preventing the patient from having to be without teeth during the healing process.  Once the tissues shrink and heal, adjustments will have to be made.
If you’ve had a metal RPD, you know how cumbersome and heavy they can be. Dentists often see them damage remaining teeth and injure the inside of the mouth. Ultaire™ AKP partial dentures are 60% lighter than metal frames! The polymer was formulated to be lightweight as well as strong, similar to polymers used in hip implants. This creates partial dentures that are comfortable, durable and biocompatible, meaning they are safe to have in your body. Unlike metal, Ultaire™ AKP is non-toxic, non-irritating and nickel-free.
They hurt my mom and the whole thing was a rip off we went in to get dentures and shave my moms now and when the swelling went down the dentures didn't fit my mother spent over thousand dollars and Theywould not replace the dentures so it was a very bad experience they should be responsible for those dentures after 30 days they should replace the dentures I shouldn't even put them in their mouth they don't fit

Needless to say that I am going to a different dentist. A man who has been in this community for a long time and has a spotless office with people who treat their patients with respect. Charges more, but worth it to be treated right. I have gone to Affordable Dentures for a while because of the pricing but every time I went, new doctor, new office people, but these people at my last time there, they are really nasty. I am also going to contact the board of health because while I was sitting in the dental chair I looked up at the light and it was filthy, nasty with what looked like old spit or blood or whatever it was. It was not clean in my opinion.


Always remove your dentures before sleeping to avoid damaging them, dislodging them, and to give your gums some time to relax. Submerge your dentures fully in warm, but not hot, water to keep them from drying out and becoming misshapen. Only use denture soaking solution if your dentures do not have metal components as the solution can tarnish the metal.

You should see your dentist 24 hours after delivery of your new dentures. It is not unusual to experience some initial discomfort. Minor adjustments can increase comfort and eliminate problems before they become more serious. Initially, a new denture may feel unusual in the mouth. The cheeks, lips, and tongue are very sensitive areas that require time to adjust. It is not uncommon to bite one’s cheek or tongue while acclimating to the new restoration. However, persistent soreness or irritation should be reported to your dentist.


HOUMA LOUISIANA, LOUISIANA -- I had six teeth left on my top in the front they started chipping. So when a new clinic opened in my town, Affordable Dentures, I was ecstatic thinking okay I can finally get things done since it was in such a convenient location. So I made a loan for 1500.00. And went in to get my teeth extracted an immediate dentures. I was happy every one was so nice. I paid cash and never felt uncomfortable about my dealings. My dentist he seemed nice. But when I left I was not given any follow up appt. He never explained anything to me. His assistant did more than him. I figured he was just busy.
PORT SAINT LUCIE, FLORIDA -- I called my heart doctor to see how long I needed to stay off my blood thinner to be able to have a tooth pulled. My heart doctor said that I could not go off meds but could get tooth pulled. I called Affordable Dentures in Port Saint Lucie, FL and spoke to lady on phone and told her my condition which she said that they needed a letter from my heart doctor. I asked what was the fax number and doctor name to have my letter faxed to and she gave me that information. Later this woman called and told me that they had received fax and gave me an appointment for April 13th at 9:30.

Canker sores are a common complaint, and are small ulcers on the inside of the mouth. Canker sores aren't contagious (as opposed to cold sores), and typically last for 10-14 days usually healing without scarring. A variety of things cause canker sores, for example, medications (aspirin, beta-blockers, NSAIDs, high blood pressure medication, and antibiotics); injury to the mouth from dental work, braces, or sports accidents; acidic foods; allergies; and diseases or conditions like celiac disease, Crohn's disease, and lupus. Canker sores can be cure with home remedies, and prescription and OTC topical and oral medication.

Conventional dentures are installed after the last teeth are removed, to allow for healing (typically six to eight weeks). There are typically separate appointments for impressions and measurements; checking a "try-in" model for fit; inserting and adjusting the final denture; and follow-up appointments to check comfort and function. Immediate (same-day) dentures are made in advance and inserted when the teeth are pulled. The University of Iowa provides an overview of immediate dentures[2] and a California dentist has a immediate denture video[3] .
She then said, "You come when I tell you to, or you won'€™t get an adjustment or repair." So I haven't been back. I live with the worst excuse for a set of partials ever made. The chewing surfaces are almost non-existent. The lowers cannot be worn. The uppers continue to chip. These substandard, inferior teeth are causing pain and suffering as well as embarrassment by not being wearable.

I have only 4 teeth on the top of my mouth. This causes me to be pretty depressed. Maybe this is why I fell for it. I went to my free consultation, this I found out later was free because they would get money later. I explained to them I have been told I have a lot of bone loss so worry I am not able to get this done. The doctor came in after the 2d exam and explained to me he could do one with 4 implants. Although not the one I wanted as I want the nonremovable, these were affordable and could be done. They then come in and give you a sheet with the full plan.
Unlike other dental practices, your dentures and denture repairs will be made right in your local office. That means fewer office visits, faster turnaround times, and affordable pricing since you’re not paying for a third-party lab. It also means your dentist and denture technician can more easily work together to make denture adjustments for a better fit.
This is my third time taking my grandpa to this establishment. Every time our “appointment” is never when we go back. We have to wait almost 3 hours to even get to the back. When I asked someone at the desk how long it would be they said “you are next to go back” that was almost an hour ago, and more than 7 people have went in before us. If you make an appointment you should not have to wait 3 hours for someone who has not made an appointment.
Most new denture issues are caused by gums adjusting to extractions and the placing of artificial teeth. These are not problems particular to me. My gums were ready for permanent partials, yet Affordable Dentures refused to provide them. At one point, Dr. **, in an effort to deflect responsibility for her inferior work, pointed to my natural tooth #22, and said, "€œIt'€™s this one that'€™s causing all the trouble. This tooth gave us FITS!"€ Tooth #22 had nothing to do with the creation or placement of her shoddy partials. My #22 is perfectly normal and was not in the way of anything. Dr.** simply had to divert attention from her fraud by projecting away from herself.

Made from high-quality materials that can mimic the shade and translucency of real teeth enamel, modern dentures offer a much more superior option to their predecessors. Not only that, modern dentures can also be customised to precisely fit your individual mouth and teeth structure. Besides enhancing the natural appearance of your smile, a well-fitted denture will significantly reduce the likelihood of the denture slipping and sliding in your mouth, causing discomfort and potential embarrassment – if they move or fall off in front of others.


Custom-made porcelain dentures are crafted to look like your natural teeth (or an improved version of your natural teeth). Great care is taken to design and fabricate a set of teeth that not only look natural, but also complement the size and shape of your mouth. Dentists may first create wax versions of the dentures so patients can try on their new teeth on before the final dentures are made; this process allows for design modifications and fit adjustments that can be applied to the final set of dentures.

Every tooth in your mouth is vital to maintaining proper alignment, and spaces left behind by one or more missing teeth can have an effect on your bite, speech, smile, and face shape. Missing teeth can cause your remaining teeth to shift and cause problems with your bite. To preserve your oral health and dental hygiene, you should weigh your options when it comes to tooth replacement treatments and choose the procedure that meets your needs.


Once the numbness wore off I could not open my mouth fully for days. It took a full week before I was out of severe pain. It honestly felt like she had broken my jaw. I decided to tough it out as I have a phobia of dentists. Once the severe pain was over my jaw was sore for the next two months. I'm fairly certain that isn't the norm for routine extractions.
This is long,but I writting this to hopefully save someone else from going through this,self pay people are at the mercy of blood sucking dentist.Well,I carefully compared several NC Affordable Dentures,I read reviews from many sources.The one near me is pretty bad,went many years ago and the currant reviews are down right scary,couple with a serious fear of dentist,did not want to put myself through that again.     Soooo the search was on,after being quoted 632.00$??? at DentalWorks!!   Who the he'll can afford that out of pocket,so after reading the reviews for this location I called asked questions,asked what I needed to bring along with time to be there.Then I read website to make sure everything was a go.Had x-rays sent over along with bringing a copy myself incase something went wrong.Website&Receptionist both confirmed needing to arrive by 7:30am.Okay,I cancelled one of my accounts (means I lost money),woke up at 4:30am then drove hour n half to A.D. Apex Highway Location.Stood in line,filled out forms,handed over X-Rays,took a seat.After watching people come in at 10 am be seen before me,denture customers get teeth pulled come back sit down in lobby again,then be called back for fittings or whatever of course started to get anxious.I just needed one extraction.There was a very loud girl there who had to have one tooth pulled as well.At the four hour mark,she asked them what was going on.Receptionist tells her denture people should all be done being treated by 3pm.So she may or may not be treated sooner.What?????Been waiting 4hours,drove almost two to get there with less then 5 hours sleep to make sure I'd be on time and it's going to be another 4hour wait??? and then that's not guaranteed.So I asked receptionist if this was the case,told her my issue,she just looked at me blankly"yep"..This information is no where on website,I told her on phone what I needed asked if there was anything I needed to know.She even said for treatments had to be there at 7:30am.NO WHERE DOES IT STATE JUST EXTRACTIONS WILL BE DONE AFTER EVERYTHING ELSE.The whole ordeal was just inexcusable.I got my x-rays and left,I am now sitting with a abscessed tooth waiting to make an appointment on Monday at one of them blood sucking offices,got small loan because the price of extractions is inexcusable too.You know what though,I Will expect it,I will also be treated better,will not automatically assume I have no other options but them so they can treat me however an if they mess up oh well.How would these ppl like to be treated this way,this issue may sound insufficient but the fact is I lost a day of my personal time along with a days work and still need to see a dentist because of thier mistake not mine. You slap the word affordable on a business,make em line up,play by your rules or else,because you know they cannot afford it anywhere else,its borderline cruel.I'm positive there has got to be a hundred other poor souls that will go through something similar to me,I if I can help one person avoid it,good!!..
Over fifty patients were seen on the day I was. They were herded through the clinic, with their dentures made as fast as credit cards can be swiped, and regardless of quality. When mine were placed in my mouth, a definite elevation on the upper right was noticeable; the length of the right side teeth was pronouncedly shorter than the other side. I noticed this after I went to my car and called in the message. The hateful assistant **, left a recorded reply, "Your teeth were made the way they are supposed to be, so I don'€™t know what your problem is."€ No mention of "We'€™ll fix it any time."€ Certainly, no consideration for the pain of the patient was forthcoming.
Dentures are artificial teeth and gums that are formed to your mouth and created by your dentists to replace lost or removed natural teeth. Dentures can either be full or partial, meaning they can either replace all teeth on either the top or bottom gum line, or just a few that are missing. Regardless of what kind of dentures you may need, they will be custom designed to fit your mouth, and visually matched to your existing teeth.
The reason the cost for either "new" (conventional, non-immediate) or "replacement" full dentures is the same is that for the most part all of the steps that the dentist must take, and the number of appointments needed, are essentially the same in both cases. Also, all of the costs they encounter (like the price they pay a dental laboratory to fabricate the appliance) are the same too.
Tooth extraction and restoration: If tooth decay or gum disease is so severe that a tooth can't be saved, it will need to be extracted. Your dentist will examine the remaining teeth in your mouth and determine if they should be removed or restored with tooth-colored fillings, inlays, onlays, or dental crowns. After the teeth have been extracted, the gums need at least two to three months to heal before an implant can be placed or an impression taken.
Can be made for either partial but mainly complete denture patients. These dentures require less visits to make and usually are made for older patients, patients who would have difficulty adjusting to new dentures, would like a spare pair of dentures or like the aesthetics of their dentures already. This requires taking an impression of the patients current denture and remaking them.[2]

Dentures that fit well during the first few years after creation will not necessarily fit well for the rest of the wearer's lifetime. This is because the bone and mucosa of the mouth are living tissues, which are dynamic over decades. Bone remodeling never stops in living bone. Edentulous jaw ridges tend to resorb progressively over the years, especially the alveolar ridge of the lower jaw. Mucosa reacts to being chronically rubbed by the dentures. Poorly fitting dentures hasten both of those processes compared to the rates with well-fitting dentures. Poor fitting dentures may also lead to the development of conditions such as epulis fissuratum. In addition, the occlusion (chewing surfaces of the teeth) tends to wear away over time, which reduces chewing efficacy and decreases the vertical dimension of occlusion, (the "open-ness" of the jaws and mouth).
MCCALLA, ALABAMA -- 5/8/18 I had all my remaining top teeth removed & an immediate denture (ID) put in. First, I was the last surgery of the day. The dentist let all his experienced staff leave & had the receptionist assist him! He had to tell her every little thing to do. She couldn't even work the suction instrument correctly & she finally just quit suctioning my mouth!
I had a really great experience with Affordable Dentures and Implants. My mom has always been afraid of dentists and didn't take care of her teeth. She also had a stroke a few years back which has created a few more barriers to treatment. It's difficult to explain to anyone who doesn't personally know a stroke survivor, but she gets antsy pretty quickly and can be a bit difficult to work with at times. She's also physically handicapped and can't use her left side, plus is having trouble transferring from her wheelchair to other seats, getting into a helpful position, and following directions, so it's a bit of a unique situation. She underwent major oral surgery in this office- multiple extractions and bone augmentation- in order to get dentures. This is something we've seen a couple different dentists for, but she has always refused treatment because she didn't like something about the office or wanted to be put to sleep in a hospital, which was out of our budget. Given her limitations and dental anxiety, I wasn't sure what to expect this time around, but I couldn't have been happier with how this office behaved. The front office has been great in terms of explaining processes, scheduling, and billing. I've also had to coordinate paratransit to get my mom to the office, and they've worked with me on times to make sure everything lines up right. Something you can probably only appreciate if you've been in a similar situation. They've also worked with us on fixing issues and missed appointments due to unforeseeable circumstances. Not only did they not scold us for missing an appointment, but they worked with me to resolve the problem that caused it- my mom's assisted living facility biffed it and didn't give her pain medicine after her surgery. :/ But, like I said, this office came through and helped- always making her care the top priority. As far as back office goes, Carlos the assistant has the patience of a saint. Seriously. We had to do a full series of x-rays because my mom couldn't stand up for the pano. My mom had trouble holding still and repeatedly failed to follow instructions. Carlos never stopped smiling and encouraging her. He had a lot of positive energy and kept joking with her throughout, which I know went a long way to making her feel good about the office. He did the same during the other visits, but the x-rays I'm sure were the biggest challenge. Jennifer assisted with the surgery. She was incredibly kind, gentle, and thoughtful. She was always doing what she could to keep my mom comfortable and looking out for her. She even went and grabbed my mom a pillow to make sure she was comfortable. Dr. Athari has an amazing sense of calm about him. He walked us through everything and talked to us throughout the procedure. My mom needed frequent breaks during the surgery and he always gave her the time she needed to regroup. He was very gentle and mindful with her throughout the procedure, and I'm certain that's what got my mom through it without issue. I cannot stress how difficult this process could have been considering the amount of care needed and the limitations of the patient. However, these folks rolled with everything we threw at them and never missed a beat. Always helpful, knowledgeable, kind, and gentle. If I had to find one negative about the office, it would be the wait times. On our first visit, one woman in the waiting room said she'd been waiting 30+ minutes. It took a day to get a call back to schedule. We waited a little while in the office too. However, when you consider that they're working with people like the person I brought in, and that it's totally impossible to predict the needs and behaviors of some of the patients who go in there, it's totally understandable. I have no doubt they took a little longer because they were treating someone else exactly as they treated us- with patience and understanding. That's worth waiting for. So, if you do go, be prepared for some short delays, but also know why those delays happen. Overall, they work like a well-oiled machine. We got to meet the whole team, including their on-site lab techs. Every single person met us with a smile and kind words. I cannot thank Dr. Athari enough for creating an environment like this. Before I close, I'd like to add a word on fees as well. I almost hesitate to call this an affordable dental office, simply because they obviously put care first. All dental offices should do what this office does and provide options, but few do. It's that commitment to patient care and letting you choose what's right for you that makes them more affordable, versus the offices that cut corners to save you a buck. That's a major difference worth noting. They also have an on-site lab, which saves costs as well. Anyway, again, sending a huge thank-you to Dr. Athari and his staff. You guys are beyond awesome.
The investigation underlined the importance of giving the patient information regarding the limitations of full dentures and information to facilitate the patient's adaptation to the new denture, advice on diet, including difficulties liable to be encountered in the use of an adequate allround diet. The investigation also showed the necessity of re-examination at regular intervals, as the patients were often unaware of changes impairing the function of their dentures. About 25% reported symptoms of functional disorders of the masticatory system. This together with other recent results underline the importance of including a functional analysis of the masticatory system in the examination and diagnosis of patients with complete dentures.
We continue to invest in our dental lab technicians by providing opportunities to advance their technical and professional skill sets.

Our technicians also receive professional recognition within the field of dental lab technology, such as becoming a Certified Dental Lab Technician.
Stuart admired the sculpture of Washington by French artist Jean-Antoine Houdon, probably because it was based on a life mask and therefore extremely accurate. Stuart explained, "When I painted him, he had just had a set of false teeth inserted, which accounts for the constrained expression so noticeable about the mouth and lower part of the face. Houdon's bust does not suffer from this defect. I wanted him as he looked at that time." Stuart preferred the Athenaeum pose and, except for the gaze, used the same pose for the Lansdowne painting.[20]
Processing a denture is usually performed using a lost-wax technique whereby the form of the final denture, including the acrylic denture teeth, is invested in stone. This investment is then heated, and when it melts the wax is removed through a spruing channel. The remaining cavity is then either filled by forced injection or pouring in the uncured denture acrylic, which is either a heat cured or cold-cured type. During the processing period, heat cured acrylics—also called permanent denture acrylics—go through a process called polymerization, causing the acrylic materials to bond very tightly and taking several hours to complete. After a curing period, the stone investment is removed, the acrylic is polished, and the denture is complete. The end result is a denture that looks much more natural, is much stronger and more durable than a cold cured temporary denture, resists stains and odors, and will last for many years.
Removable partial dentures. Although these don't require grinding down adjacent teeth, they are not nearly as stable or comfortable as dental implants and can affect speech and eating. This type of restoration is less expensive but doesn’t look as natural or function as well as an implant-supported crowns. The bone underneath a removable partial denture may deteriorate over time, changing the appearance of your smile and face.
I also am so afraid that my heart doctor may be upset because I was so desperate to have my tooth pulled that I put the dental assistant on my cellphone with my doctor's nurse and she talked really nasty to her. She told my doctor "No dentist worth his weight would accept that fax". Then the dentist told me that he has never had a problem with a heart doctor giving him the note he needed and that they were just after money because they said I would have to have a cardiac evaluation. I told him that I really liked my heart doctor.
One of the major treatments for dealing with missing teeth has always been dentures. Known by its less flattering name ‘false teeth’, there is a certain stigma that has unfairly dogged the use of dentures. This is mainly because old dentures are known to be wobbly, ill-fitting and artificial looking. However, thanks to advancements in modern dentistry, today’s dentures no longer conjure images of fake-looking choppers.
dr recommended immediate dentures. what I read on immediate dentures was that they are generally temporary. apparently per this dentist not so. now wants to charge 380 for reline knowing the bone was receded a lot and would have to reline right away. given all I know now, I would never go to this dentist again. ask more questions, get more estimates from other dentists. upper plate only has 12 teeth in it. inside of teeth do not touch lower permanent teeth, gap of at least 1/8 " between gm and inside of plate, gum does not touch bottom of gums at all.
After implant-supported dentures are in place, patients should properly care for their teeth and gums. The dentures, gums, and tongue should be brushed twice a day. Patients should also floss daily to remove debris between the teeth; though false teeth won't become damaged by decay, plaque build-up can still cause gum disease and bad breath. Patients with dentures should also schedule dental visits every six months so their dentists can check the fit of the dentures and look for signs of dental problems. 
In addition to health risks, not receiving partial dentures when you need them can lead to a lack of confidence. Many people become ashamed of their smiles once they lose teeth, and they never want to laugh or express joy or happiness. When you smile, you appear friendlier, more confident, and more successful. You can gain back your healthy self-esteem by visiting to receive realistic-looking dentures that look natural and will feel natural with time, too.
It is often necessary to pull any remaining damaged teeth before getting dentures. Tooth extraction typically costs $75-$450 per tooth for a simple extraction and $150-$650 or more per tooth for a surgical extraction. Depending on the number of teeth to be pulled, the total cost of getting dentures can be $1,500-$20,000 or more for a full set (uppers and lowers). CostHelper readers report paying $2,000-$18,000 for a full set of removable dentures including tooth extractions and other preparation work, at an average cost of $9,063.
Have your dentist evaluate your needs, as partial dentures are used if there are a larger number of teeth that need to be replaced and if there is a risk of more tooth loss while bridges work best for smaller gaps on the same side of your mouth. Additionally, partial dentures are easier to adjust and repair and are usually less expensive. However, partial dentures can become broken or lost while bridges remain safely fixed to your teeth.

Often more affordable than dental implants, dentures are removable dental appliances meant to look and function like natural teeth. Many patients who have experienced tooth loss and are concerned about the loss of both functionality and aesthetics turn to dentures to meet their needs. The cost of dentures varies considerably, according to geographical location, the dentist, and type of dentures.

We paid for extraction and dentures and it was for 2 sets one to wear until gums heal and so we did but it took so much time because they said not ready on gums. This went on & on and then they would NOT answer their phone when we called for the permanent set (we paid for) and they would not return messages. So 2 years have gone and I am left with the first set used until gum set and they are awful and this place is in Odessa, Texas. They are cheats and liars.
Extractions were the main cost saver ($30 each) but you have to pay for the dentures first ($500). Don't think they would have accepted me if I only wanted extractions. TOOK 5 MONTHS and 6 or 7 visits to get these "immediate" dentures. Look good out of my mouth but when I smile u see all the bottom teeth and hardly any top ones. LOTS of overbite make biting PB&J sandwich impossible.
Occasionally, denture wearers may use adhesives. Adhesives come in many forms: creams, powders, pads/wafers, strips or liquids. If you use one of these products, read the instructions, and use them exactly as directed. Your dentist can recommend appropriate cleansers and adhesives; look for products with the ADA Seal of Acceptance. Products with the ADA Seal have been evaluated for safety and effectiveness.
