A dental implant is one option for replacing a tooth. Implants are manufactured devices that are placed surgically in the upper or lower jaw, where they function as anchors for replacement teeth. Implants are made of titanium and other materials that are compatible with the human body. An implant looks and feels like a natural tooth. It fits securely when you chew and speak. A single-tooth implant is a free-standing unit and does not involve treatment to the adjacent teeth. With a dental implant, the surrounding teeth can remain untouched if they are healthy, and their strength and integrity may be maintained. The implant can stabilize your bite and help prevent problems with the jaw.
