Q. Is the treatment only for people who have lost all their natural teeth, or can it be used to replace only one or two teeth?

A. Implants may be used to replace any number of natural teeth. Among young adults in particular, an implant is often used to replace a single tooth lost to an athletic, bicycling, or other accident, or to provide artificial teeth where natural teeth never developed. In older patients, implants are often used to replace an entire mouthful of teeth.
