Crowns are caps which cover teeth that are heavily restored (generally more than 50% filling) or have had a root canal. Research has found that such teeth are more prone to fracture. Crowns are placed to cover the tooth right down to the gums, to protect it from breakdown. Bridges are essentially 2 or more “anchor crowns” fused to “false teeth” which act as a single unit to replace one or more missing teeth in a region of your mouth.
Bridges, like crowns, are cemented in place permanently. This is in contrast to partial dentures, which are removable and stay in place with hooks on existing teeth rather than cement. Crowns and bridges can be made of metal, porcelain, or a combination of these materials. Veneers are an aesthetic treatment used on front teeth. They are essentially “half crowns” – as such they are very conservative and little tooth structure is removed. They are made of porcelain and cover the front portion of the tooth to correct discoloration, misalignment, wear, chipping or gaps between teeth.
