If you've lost teeth or need to have them replaced, dental implants are often a great way to go. They consist of an artificial root, which is usually made of titanium, and an artificial tooth, which is usually made from porcelain, and crafted to look like it's always been one of your own.
They provide strength and integrity to your jaw bone, and they will last for years. In some cases, an occasional re-tightening might be required, or the tooth and/or root replaced.
Perhaps one of the best advantages of an implant is that they are cared for just like your natural teeth - through normal preventive dentistry!
