Dental Implant Dental implants are surgical-grade root devices that support permanent tooth prosthetics that are manufactured to last a lifetime. These artificial roots are anchored in the bone beneath the gums where they become fused into the jaw. A crown is mounted atop the implant for a long-lasting and natural looking smile. Many dentists and patients prefer dental implants because they offer the same function as natural teeth and also help prevent bone atrophy in the jaw. Dental implants may be used to replace a single missing or damaged tooth or to restore an entire smile.
