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.
Teeth can fall out for a number of reasons, ranging from genetics to drug abuse. Most commonly, teeth are removed or fall out on their own due to severe tooth decay. Neglect to upkeep oral hygiene or not seeking proper treatment for damaged teeth, can lead to the onset of decay which in turn leads to loss of teeth. Visiting you dentist in 6 month intervals is a good preventive measure to spot any early signs of decay.
