Review (5/5): the periodontist saw a difference!
I purchased this toothbrush 6 months ago after my first visit to the periodontist, when I was told that some of my pockets had turned into "5"s (I'm fairly young, so this was not a good turn of events). I'd used a sonicare toothbrush in the past (over $100 for the model), and I hadn't noticed a major difference - still got cavities same as ever, so when it died I went back to a manual toothbrush. Anyways, I just had a check-up after 6 months of faithfully using the oral-b electric toothbrush, and my 5's were down to 4's. Not to mention that my teeth feel noticeably cleaner after using this brush, and the 2-minute timer ensures that I do brush for a full 2 minutes (which I never did with a manual toothbrush). I'm a fan.
