USED to be great. Not any longer. Can no longer recommend. I had to find another dentist and have expensive and painful addtional treatment to correct the error he first made, and then compounded. It has had a permanent and extremely negative and detrimental effect on my entire dental health, (including my bite, and the alighnment of my jaw) and ended up affecting not just the original tooth, but both teeth on either side AND the two teeth below.
