Dr. Williams did 4 crowns for me all at once. He did an excellent job. He took special care to make sure there was no pain. Unfortunately he moved to an office out of my area. I have had compliments on the work he did from a new dentist I started going to since Dr. Williams moved. The new dentist did two crowns that I have had nothing but problems with since he did them and is recommending another crown to be done. I highly recommend Dr. Williams to any one looking for a dentist.
