A dental implant is the tooth replacement option that is most like a natural tooth. You can think of a dental implant as a root replacement.
1) Teeth on other side of the missing tooth are not used to support the missing tooth, as in a partial denture or a bridge.
2) The bone is stimulated just like if the root of a tooth was still there. This preserves the bone and keeps it from resorbing away, unlike a partial denture or bridge.
3) Dental implants are not susceptible to the bacteria that causes tooth decay.
Dental implants can be used to replace multiple missing teeth with either a dental implant bridge or as anchorage for a complete or partial denture.
Dentures are difficult to wear comfortably. We can use dental implants to snap in a denture in place. Denture adhesives and pastes are no longer necessary.
