Think of dental implants as artificial tooth roots, similar in shape to screws. When dental implants are placed in your jawbone, they bond with your natural bone. They become a sturdy base for supporting one or more artificial teeth, called crowns. A connector known as an abutment is placed on top of the dental implant to hold and support your crowns. The crowns are custom-made to match your natural teeth and fit your mouth. Modern dental implants have been used successfully for many years. They are the strongest devices available to support replacement teeth and even better, they allow these new teeth to feel, look and function naturally.
