Dental crowns and bridges are custom fitted tooth prosthetics that are used to replace or restore damaged or missing teeth. Crowns also known as caps, are fixed over the surfaces of natural tooth structures or dental implants. Bridges are used to fill in the gaps left by missing teeth and are anchored in place by natural teeth on either side of the empty spaces. Both crowns and bridges are permanent, they may not be taken in and out of the mouth. Patients who choose a crown or a bridge to restore their smile achieve both the function and appearance of natural, healthy teeth.
