Dental implants are artificial tooth roots that anchor into the jawbone to form a stable foundation for crowns, bridges, partials or dentures. They help to preserve bone in the jaw, maintain the ability to chew and speak, eliminate the discomfort and embarrassing moments associated with dentures, and support the shape of the face while promoting self-esteem and confidence. likely candidates for dental implants are those that have lost a tooth, or teeth, due to periodontal disease or injury.
