A dental implant is a titanium post surgically placed into the jawbone to replace a missing tooth root. It provides a strong foundation for fixed or removable replacement teeth like crowns or dentures. The implant fuses with the bone over time through a process called osseointegration. This procedure helps restore chewing function, appearance, and prevents bone loss in the jaw. Dental implants are a durable, long-term solution for tooth loss with proper care and hygiene.
