If you are missing a tooth or multiple teeth, an option may be a single or multiple dental implant teeth, particularly if it is one that is part of your smile. Once the tooth is extracted, the dentist can place a dental implant which is left to fuse with the bone for awhile. Once the fusing is done, an abutment is installed onto the implant and a crown is mounted on the abutment. The result will be a "free standing" artificial tooth which feels like a natural tooth and likely cannot be recognized from a real one.
