Porcelain crown(s) can be used to change the colour, shape and appearance of broken or decayed teeth.
A tooth with a very large filling may very often be restored by a porcelain crown. A tooth that has a root canal filling also benefits from a crown as these teeth become brittle and so are more prone to fracturing.
The tooth is prepared leaving a strong core base. The crown itself then fits snugly over this, making it strong and giving it the shape and contour of a natural tooth.
