When a tooth is missing, the resulting gap will allow nearby teeth to tilt or drift from their normal position, and the teeth above the gap will move downward. Aside from the obvious cosmetic problem, the changed positions of these teeth can lead to severe bite problems causing pain in the jaw and headaches in the future.
Missing teeth should be replaced to keep other teeth in their normal position. This can be done by means of a fixed bridge or a dental implant. Both of these treatments offer a good functional and cosmetic result.
