I had 6 veneers done by Dr. Schell.....after having them cemented in place they looked great, how every when it came to eating with them on they hit on the upper top 6 teeth cauing me great pain. I went back to Dr. Schell for the next 4 years for several adjustments in which he ended up grinding a total of 20 teeth...trying to make his veneers fit into my bite. I ended up with TMJ because of him.
