Review (4/5): Gentle, but maybe that's a good thing...
I used to use the standard Oral B electric toothbrush. I found it did an excellent job of keeping my teeth clean and white between dentist office visits.
When I first used the Sonic, I was quite surprised that the bristles did not rotate like they did on my old toothbrush. They simply vibrate. My initial impression was that this toothbrush wasn't going to 'power-wash' my teeth like the last one, but perhaps this is a good thing? My boyfriend thought that the old version is so strong and powerful that there's a chance it could loosen fillings, etc. That's not so much a concern for me because as of yet, I don't have fillings, but for people who do, you might want to get the Sonic version as opposed to the regular Vitality or other non-sonic brushes.
