In some cases, oral surgery is performed to correct bony ridges that may interfere with the stability of the denture. In other cases, the remaining teeth may need to be extracted before placement. Once your dentist has decided that dentures are right for you, he will make an impression of the gums to identify every ridge and crevice to ensure the best fit possible.
If you've recently lost your teeth and received an immediate denture, it's normal to find some tissue shrinkage and bone loss occurring. Therefore, in several months you may find that your immediate dentures no longer fit well. You will have two choices at this point: You can have your immediate (temporary) dentures re-lined. This means that material is added under the denture's base to better conform to the new contours of your alveolar ridge. A better option is to move to a set of conventional full dentures, which will last longer and fit better. With proper care, dentures offer a functional, aesthetic and economical solution to the problem of tooth loss.
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.
