I would highly recommend Dr. Mel Tanen at Yonge and Uplands (just south of Hwy 7). He is a great dentist, his hygenists have been fantastic with our son, as well as with us, and the rates are quite good (if your benefit plan doesn't cover 100%, or if it is based on outdated ODA billing rates, this can be significant). Dr. Tanen's phone # is 905-889-2181.
