Overdentures are an alternative that can be used if traditional dentures prove to be extremely uncomfortable or if you have a few natural teeth left. Overdentures are fitted over the roots of natural teeth and either rest on these or on dental implants, if there are no natural teeth to fit over. Some find this type of denture more comfortable and they are also easily removable.
Dentures are removable dental appliances that replace missing teeth. Unlike dental implants and dental bridges, which are more or less permanently affixed to the bone, dentures are prosthetic teeth attached to a supporting structure. Dentures can be removed at night, for cleaning, or whenever desired. The most affordable dentures are those made with traditional plastic prosthetic teeth, but even more expensive porcelain cosmetic dentures usually cost less than implants.
Whether you've lost one tooth or many, chewing and smiling can become more difficult because of the gaps left behind. Partial dentures are an economical solution to replace the missing teeth and fill in the spaces, improving chewing ability and the confidence to smile. A partial denture in place will also help keep your natural teeth from shifting, lowering the risk of losing those teeth in the future.
Patients that want a more stable and comfortable denture alternative may be interested in talking to their dentists about dental implants and dental bridges. Although both of these treatments tend to be more expensive than dentures, they generally offer a more precise fit and better chewing ability than dentures. Patients can also have a tooth-colored ceramic or porcelain bridge or implant restoration placed for a more natural looking appearance.

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]

[...] a composition for the purpose of making of artificial teeth either single double or in rows or in complete sets, and also springs for fastening or affixing the same in a more easy and effectual manner than any hitherto discovered which said teeth may be made of any shade or colour, which they will retain for any length of time and will consequently more perfectly resemble the natural teeth.[8]

The lower denture's teeth surface is even with the gum surface making the lower plate essentially flat. I mean there is no white tooth higher than the pink gum material. Not knowing the difference and trusting these so called "professionals," I have worn the partials for 8 years now and my bite is so off that my upper and lower front teeth butt against each other and has resulted in wearing them flat, taking the edge off them.
Remember: You can do serious harm to your denture and to your health by trying to adjust or repair your denture. Using a do-it-yourself kit can damage the appliance beyond repair. Glues sold over-the-counter often contain harmful chemicals and should not be used on a denture. If your denture breaks, cracks or chips, or if one of the teeth becomes loose, call your dentist immediately. In many cases, dentists can make necessary adjustments or repairs, often on the same day. Complicated repairs may require that the denture be sent to a special dental laboratory. 
Denture adhesive is a paste or glue that helps the denture adhere to the supporting tissues instead of relying on suction or clasps. Sometimes the adhesive is called denture cream. A small amount of denture adhesive can be applied evenly to the clean surface of a denture to enhance stability and retention. It shouldn't be used to compensate for a poor-fitting denture or as an alternative to visiting the dentist for regular checkups.

Partial dentures are a removable appliance that consists of artificial or prosthetic teeth attached to a gum-colored plastic-acrylic base. Partial dentures can be secured more and held in place by a metal framework or tooth-colored attachments. Partial dentures are used for patients who are missing one or more natural teeth, but not all of their teeth. These dentures work with both the upper and lower jaw, remaining secure in either location during use.

Premium heat cured dentures can cost $2,000-$4,000 per denture, or $4,000-$8,000 or more for a set. Dentures in this price range are usually completely customized and personalized, use high-end materials to simulate the lifelike look of gums and teeth as closely as possible, last a long time and are warranted against chipping and cracking for 5–10 years or longer. Often the price includes several follow-up visits to fine-tune the fit.
The Premium Denture is very high in natural appearance. It features enhanced natural appeal, wear and stain resistance, with detailed customization. As with the UltimateFit and EconomyPlus Dentures, the Premium’s extra-high density teeth are first set in wax for you to try in. Changes may be made at that time. After you have approved the look of your Premium Denture, the lab will custom finish your denture in the permanent acrylic base material. This additional customization results in a more natural look.
