A missing tooth is a serious matter. Teeth are made to work together. When you lose a tooth, the nearby teeth may tilt or drift into the empty space. The teeth in the opposite jaw may also shift up or down toward the space. This can affect your bite and place more stress on your teeth and jaw joints, possibly causing pain.
Teeth that have tipped or drifted are also harder to clean. This puts them at a higher risk for tooth decay and gum disease.
When a tooth is missing, the bone may shrink. If that happens, it may change the way the jawbone supports the lips and cheeks. Over time, this can make your face look older.
