A dental implant is as close to literally replacing a tooth as you can get. They have been around for decades but really became mainstream within the last 10 years or so. An implant is placed exactly where the root of a tooth would go into the bone. Over a few months the implant fuses to the bone and then we can attach various restorations to it depending on the circumstance. Implants can replace one tooth or several implants can be placed to replace an entire arch or even stabilize a denture.
