A missing tooth can cause more problems with your bit than just an unsightly appearance. Teeth may shift to fill in the space, changing your bite and smile. It can also cause your jawbone to shrink, which can change your facial structure and appearance, even when you aren’t smiling. Everyday tasks such as talking or chewing become more difficult when teeth are missing. Though bridges and dentures can be a solution to missing teeth, they are less ideal than a permanent implant. An implant takes the place of a missing tooth or teeth and preserves the jaw bone, preventing it from shrinking and changing.
