Most of the crowns which was done by Dr. Taddy, needed to be replaced within 2-3 years. The quolity of his work is very poore. He dii some work which was not necessary and actualy replaced good crowns for a bad crowns. I lost 2 teeth because of his bad work and had to spend over $9,000 to fix his work by putting implants. I would not recommend this doctor to anybody.
