When a patient loses a tooth or multiple teeth, a dental implant is often the best option for replacement. Dental implants are tiny posts that look like screws or cylinders. They are surgically placed into the jawbone where teeth are missing. Implants provide a stable foundation for the attachment of a replacement tooth or a firm anchor for a partial or denture. A fully restored single implant looks just like a natural tooth and can even be stronger than one. They can last a lifetime if properly maintained.
