So, I just bought a new electric toothbrush. I used sonic care for the past seven years on the advice of a dentist. Neither sonic care nor a regular tooth brush did a really good job at cleaning my teeth.
Last week, I bought an inexpensive $30 Braun Oral-B vitality. I have to tell you that I feel that I have been using the wrong toothbrush for years. The inexpensive Oral-B (the kind with the rotating head) cleaned my teeth 10 times better than the sonic care (or a regular tooth brush), and the replacement brushes are one tenth the price of sonic care.
I guess I am now an Oral-B evangelist. I wish I would have known this years ago.
