Thin pieces of porcelain used to recreate the natural look of teeth for those looking to make slight position alterations, or to change tooth shape, size, and/or color.
Root Canal

Treatment used to repair and save a tooth that is badly decayed or infected. This occurs when the interior portion of the tooth, the pulp, where the tooth's nerves and blood supply are located, becomes infected or damaged. Root canal therapy removes the damaged pulp of the tooth so the tooth can be preserved and an extraction can be avoided.
