A missing tooth can be replaced with a crown attached to an implant. The crown replaces the part of the tooth you can see above the gumline. It looks exactly like the other natural teeth in your mouth. The implant actually replaces the root of your tooth. It is made of titanium, and permanently attached your jaw, just like a natural tooth root. When more than one tooth needs to be replaced, dental implants can also serve as anchors to secure bridges, and permanent or removable dentures.
