Support is the principle that describes how well the underlying mucosa (oral tissues, including gums) keeps the denture from moving vertically towards the arch in question during chewing, and thus being excessively depressed and moving deeper into the arch. For the mandibular arch, this function is provided primarily by the buccal shelf, a region extending laterally from the back or posterior ridges, and by the pear-shaped pad (the most posterior area of keratinized gingival formed by the scaling down of the retro-molar papilla after the extraction of the last molar tooth). Secondary support for the complete mandibular denture is provided by the alveolar ridge crest. The maxillary arch receives primary support from the horizontal hard palate and the posterior alveolar ridge crest. The larger the denture flanges (that part of the denture that extends into the vestibule), the better the stability (another parameter to assess fit of a complete denture). Long flanges beyond the functional depth of the sulcus are a common error in denture construction, often (but not always) leading to movement in function, and ulcerations (denture sore spots).
I am missing almost all of my upper teeth and am considering full dentures. What are the costs for extraction and for the dentures? Also, what is the timeframe for ordering and wearing the new dentures after extraction?Answer: The fee for removing your remaining teeth varies upon the complexity of the procedure required to remove your teeth as well as your geographic location. Some dental schools, including hospital-based programs, may offer reduced fees if you use a resident (a dentist in training for additional skills) or a dental student to perform the procedure (under the supervision of licensed dentists). The timing of the placement of the dentures can vary widely. Dentures may be made prior to the removal of the remaining teeth and may be inserted the day the teeth are extracted, or the teeth may be removed and healing allowed to take place before the dentures are delivered several weeks or even months later. Most patients want to have dentures sooner rather than later, but dentures placed soon after or immediately after teeth have been extracted may need to be adjusted or replaced after the healing process is finished.Response provided by the American College of Prosthodontists.

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.
