1.Preservation of natural and healthy teeth

The traditional way to replace a missing tooth is to grind away tooth structure from the adjacent healthy teeth to make room and anchor a bridge to replace one or more missing teeth. This process can damage the pulp (nerve) of the natural tooth, requiring a root canal immediately or years after treatment. The root canal treatment will further weaken a formerly healthy tooth. Also the chance of getting decay under traditional bridgework is far greater then if a single tooth were crowned. Statistically 30% of all bridges fail within 15 years. Implants have the highest success rate of any dental restoration.

2.Preventing bone loss

Once a tooth is lost permanently, the bone that was surrounding the lost tooth starts to resorb. Teeth that were behind the lost tooth can move forward and start "falling" in to the empty space of the lost tooth.. The tooth opposing the missing tooth can also start to move in to the vacant space. Implants can arrest bone loss.

3. Anchor a denture

When all the teeth are gone, bone resorption progresses indefinitely. A denture can become frequently ill fitting and loose. Chewing power and the sensation of texture and taste of food will also decline with a traditional denture.
