An implant is an artificial tooth root made of titanium metal. The fixture is surgically embedded into the jaw bone and after a period of time to heal an abutment is placed. The abutment part of the implant sticks out of the gums and is attached to the fixture. Soon after a crown can be made to fit onto the abutment. Dental implants can replace a single tooth or several teeth. If you are missing all of your teeth implants can also be used to support a full bridge or denture. Dental implants allow people with missing teeth to be able to smile, speak, and chew well and comfortably.
