Dental crowns are custom-made, permanent restoration. They are hollow tooth shaped “cap” cemented onto a prepared natural tooth. When a tooth is cracked, contains a large filling, and/or has been root-canal treated, it is at increased risk of fracture.  A crown protects and reinforces the remaining tooth structure. once cemented into place, crowns completely cover the entire visible portion of the tooth producing a functional and aesthetically pleasing tooth that blends in with the remainder of the natural teeth.
