In general terms, a crown is needed on a tooth that is weak. It protects it and prevents it from breaking. Extended decay, big restorations, fractures are some of the common causes of tooth weakness.
A tooth that is endodontally treated (root canal treatment) is also weak. The access hole that we make in order to clean and treat the canals of the tooth makes the tooth prone to fracture when strong forces apply to the tooth. Therefore, posterior teeth that are root treated require a crown so they are protected. The crown covers the tooth from all sides.
The crowns at Dental Ariston are only full ceramic crowns, with no metal parts. They resemble the natural tooth they are covering and they are made with the highest attention to detail so they perfectly fit and blend with the adjacent teeth. Others won’t be able to tell your crown isn’t a natural tooth.
