The black line

I get asked all the time, by patients, why they have a little black line at the base of my crown. The answer to that is because your crown is made partially of metal. It is called a porcelain fused to metal, or PFM, crown. The metal is what gives the crown the strength and the porcelain is what is layered over the top to make it look like a tooth.
That little black line that people see is the metal sneaking a peek out from underneath the crown. And unfortunately that little line will never go away.

In Dr. Ellis' office we do our very best to keep up on the latest technology. This includes crowns that are made of NO METALS whatsoever. This way there will never be a little black line showing through.
These new crowns are called Bruxzir crowns and they are made completely out of zirconium. This substance is incredibly strong and does not present the problem of older PFM crowns with there black lines or chipping of porcelain.
Technology is moving fast and we are trying to to stay up with it. Come in and talk to us today about a beautiful new Bruxzir crown.
