I've been contemplating the move from a regular toothbrush to either an Oral B or a Sonicare. Both get amazing reviews on Amazon so I can't use that to make my decision. I don't know anything about either of them so am looking for any experiences you guys have with either of them. Apparently I don't brush good enough near my gums and the dentist said I need to do better. The problem is they are a little sensitive (I assume because of no flossing) so looking for something that won't destroy my gums in the process.
