I'm thoroughly impressed!
Let me start by saying that I can only give you my experiences, I'm not an electric toothbrush expert.  I don't know why they work, other than the stuff on the box about pulsating and vibrating.<br />That cleared out of the way, I am amazed with this toothbrush.  I have even tested it against a normal toothbrush.  I used the electric the first day I brought it home (the day after my dental appointment).  I had just had a cleaning at the dentist, and was surprised to find that my teeth felt like they had when I left the dentist's office.<br />  I figured, "Oh, it must be because I just had my teeth cleaned," so I had an experiment.  The next evening, I brushed my teeth with my regular toothbrush.  I scrubbed the dickens out of my teeth.  They felt about like they used to.  Then I took the electric to them for about 20 seconds, just enough time to pass it over all my teeth quickly, and there was a definite improvement.<br />One down-side:  I find that I can't keep from a little toothpaste drool.  It's not messy, I just have to wash my chin afterwards (and I have a beard.)<br /><br />******Final Thoughts*****<br />Now, for why I bought THIS brush... It really is dentist recommended:<br />  The last time I was at the dentist, (about two months before this review) he gave me no choice in the matter, he said I HAD to go buy an electric toothbrush, and he said this was the one to buy.  He told me about another one that was a couple of dollars less, but firmly stated that this was the best one to buy, so I did.<br />Since then I have been back to the dentist twice (for fillings :P )and he can tell a marked difference.  So can I.  This toothbrush has my heart. (if a bathroom appliance can do such a thing)
