Dr. Forbes is generally a very competent doctor, however, he did a crown on one of my back molars and half the enamel coating cracked off the crown after a few weeks. Rather than begin again with a new metal foundation, he sent it back to the lab and they recoated the crown with additional enamel which made it larger then the original cast. Putting it back in was a very tight fit because it was larger than my original tooth. I have very closely spaced teeth, so this larger crown caused all the rest of the teeth to shift out of allignment, so now my lower front teeth are crooked. Very discouraging after having two rounds of braces to correct the crowding...
