If a tooth is extracted or missing for some other reason, it is now possible to replace it using dental implants. An implant is a new tooth made of metal and porcelain that looks just like your natural tooth. It’s composed of two main parts: One part is the titanium implant body that takes the place of the missing root, and the second part is the tooth-colored crown that is cemented on top of the implant. In addition to tooth replacement, implants may be used to anchor dentures, especially lower dentures that tend to shift when you talk or chew. For patients with removable partial dentures, implants can replace missing teeth so that you have a more natural-looking smile.
