Sonicare Advance 4100 Electric Toothbrush

I started using the Sonicare Electric Toothbrush, because my dentist recommended it.I used it for six months before by next visit and the hygenist noticed the difference at my next cleaning.I drink coffee so it helped keep my teeth whiter than with a regular toothbrush.I like the timer on the handle that lets me know that I have brushed for the recommended amount of time.The dentist also said my gums had a noticeable improvement.The battery seems to charge well, I havent had any trouble with it running low while I am using it.The initial cost is a little high, but well worth the better check ups I am getting at the dentist.The brush heads are replacable and seem to last as long as my regular toothbrush did.I was skeptical at first that I would see that much difference, but I was amazed at what a difference it really made.
