Sonicare Advance 4100 Electric Toothbrush By uaezarb on Feb 11, 2008 - Updated Sep 18, 2011

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.
