Crowns A dental crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. Crowns protect and strengthen tooth structure that cannot be restored with fillings or other types of restorations. Why You May Need A Crown: Broken or fractured teeth Cosmetic enhancement Decayed teeth Fractured fillings Large fillings Tooth has a root canal Porcelain Crowns Although there are several types of crowns, porcelain (tooth colored crown) are the most popular, because they resemble your natural teeth. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain caps are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile. Contact Nash Dental Care to learn more about porcelain crown options.
