Patient discussion about sonicate

Q. do you know what are the pros and cons of the Sonic toothbrush from Oral B (electric tooth brush)? last night, my best friend raved about it for a whole hour. My dentist told me to use a soft brush (number 35) to clean my teeth and that the electric brushes are a bit over rated. My friend specifically told me about the Sonic product and told me that it also makes his teeth whiter. I wanted to know if anybody has any knowledge or experience from first hand about this product or any good information about it.

A. Thank you for the frank answer. I wonder if I can find a really soft electric toothbrush
