Crowns, or caps for teeth look and function just like natural teeth. If one of our doctors recommends a crown your tooth has enough decay that it cannot hold a filling, or if your tooth is cracked or broken and in danger of cracking down into the root if left unattended. A crown covers your tooth completely. It fits snugly at the gum and protects what remains of the natural tooth. They can be made of gold or porcelain fused to a metal substrate for strength and crowns can also be made entirely from highest ceramic and porcelain.
