When a tooth is lost, the jaw bone that helped to support that tooth begins to atrophy, causing the teeth on either side to shift or tip into the open space of the lost tooth. Also, the tooth above or below the open space will start to move towards the open space because there is no opposing tooth to bite on. These movements may create problems such as decay, gum disease, excessive wear on certain teeth, and TMJ (jaw joint) problems. These problems and movements do not result immediately, but will eventually appear, compromising your chewing abilities, the health of your bite, and the beauty of your smile.
