CROWNS
A crown is a type of dental-restoration device that is used to give form and strength to a tooth that is still viable but has suffered extensive damage.
Crowns may be used individually, for example, after performing a root canal, or in conjunction with other structures, such as when used on top of a dental implant or an all on 4 solution.
Unlike fillings, a dental crown is normally prepared in a dental laboratory from a mold taken by the dentist. The materials can be porcelain, zirconia, gold, stainless steel, composite, or in combinations of metal and porcelain.
