A dental implant is a metal titanium post integrated with the bone that replaces the root portion of a missing tooth. A variable amount of healing time is required before an artificial tooth (crown) can be placed on the extension of the post on the dental implant, giving you the look of a real tooth. For a group of missing teeth an implant can be used to anchor a bridge instead of having a removable denture. To place a dental implant an Oral Surgeon will do a surgical procedure. The success of implants depends on the health of the tissues in the mouth.
