Dental implants are tiny titanium posts that are surgically implanted into the jawbone where teeth are missing. These titanium posts act as artificial tooth roots, and typically support a dental crown. Together, the implant and crown act as a permanent replacement for a missing tooth. Dental implants restorations that function and look much like natural teeth do. They are fixed, and so cannot be removed like dentures. With proper care and good oral hygiene, dental implants can last a lifetime.
