If a tooth is lost, the replacement which looks and feels closest to a real tooth is an implant.
A titanium covered screw is placed into the jawbone, where the bone gradually grows into it and it becomes firmly attached. Once this healing has taken place a new tooth (crown) made of Zirconia can be screwed into place to replace the missing tooth. A successful implant looks and feels almost exactly like a real tooth and can last for many years with no problems if well cared for. Any surgical or invasive procedure carries risks. Before proceeding you should seek a second opinion from an appropriately qualified health practitioner.
