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.
The office people and assistants must be low wage workers. They have the typical low paid, high stress lack of concern for the patient. The person who did my form did not do it well. That was evidenced in the quality of the temporary denture. The Dentist who did the extractions was the absolute best dentist I have ever seen in my 55+ years. They give you a pill to take an hour before you get there and if needed, one when you arrive. It relaxes you and one was enough for me. I was ready to go to sleep. They took me straight in and the dentist took 20 minutes numbing every tooth with a local anesthetic.
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.
After deciding on having the extractions and the full plate, I decided on the "Premium" denture. You can see 3 different types of dentures. Economy, Good and Premium. It's pretty easy, if you want the longest lasting, then get the premium. Economy dentures often break after a couple years... I had to pay the full amount right then, before they would go any further. They want all the money in advance or they don't do the dentures. Be prepared to pay up front in full, before you go, or don't go.
Later that afternoon I came back to have 16 teeth extracted. I got to the office and waited about 30 minutes before I was seen. I got to the back and began injections. After this I went to a full blown panic attack and came close to passing out. The one positive is the dentist who was working on me took it in stride. I wasn't treated disrespectfully and after about 30 minutes the panic subsided and she was able to finish my injections and begin pulling teeth.
