If your tooth is deteriorating, what we suggest is to put a crown or “cap” on top.
Crowns can be made out of all kinds of materials: gold, silver, and steel. However, the highest quality crowns are now made out of a type of ceramic called Zirconia.

They are durable, milled from a solid piece of zirconia, so there is no risk of porcelain chipping off of a metal framework. Zirconia crowns are also aesthetically pleasing! They are made to match the shade of your existing natural teeth so well, they are undetectable by the naked eye!
