Dental implants are by far the most common and ideal method of replacing a missing tooth or teeth. In the last quarter-century or so, they have unquestionably altered the direction of dentistry. A dental implant is a titanium post that is surgically positioned under the gum line in the jawbone to serve as a tooth root. An implantologist can place a crown on top of the implant to give it the appearance of a natural tooth after it has been implanted. Tooth implants not only look and sound like natural teeth, but they also function the same way.
