Ceramic crowns can replace damaged teeth that still have their root. The biggest advantage of crowns and bridges is that they are almost indistinguishable from your natural teeth. They have very similar physical attributes as natural teeth (they expand in the heat and contract in the cold) and naturally transmit light. Ceramic material is also hypoallergenic and, compared to crowns with a metal core, they do not oxidize or emit any substances. Modern technology now being used ensures the ceramic material is strong.
