I highly recommend this dentist. He was recommended to me by friends who are pickier than anyone I know — and they were right… he’s great! I have always had cavities and dread getting them filled… but I let Dr. Greenwald do it and WOW, the FIRST time ever I didn’t feel the needle! He said it was some new numbing stuff and it really worked. My teeth are doing great. He’s a great dentist!
