Finding replacements in living people hasn't been easy: Gum ridges
that serve as seats for dentures tend to wear down, and permanent implants often break down over time.
The tissues in the mouth change over time, and bone and gum ridges
shrink, which can result in ill-fitting dentures that make eating uncomfortable or downright painful.
At a regular dental examination, the dentist will examine your mouth to check for problems with the gum ridges
, the tongue and the joints of the jaw, as well as screen for oral cancer.
