The dental implant is today's state-of-the-art tooth replacement method. It consists of a very small titanium post (the actual implant), which is attached to a lifelike dental crown. The crown is the only part of this tooth-replacement system that is visible in your mouth. The implant itself rests beneath your gum line in the bony socket that used to hold your missing tooth. Two, four or more implants can be used to support multiple crowns, or even an entire arch of upper or lower replacement teeth. Whether you are missing one tooth, several teeth or all your teeth, dental implants are preferred by doctors and patients alike.
