Review (5/5): Excellent toothbrush - a must have.
I've been using the Sonicare toothbrushes since they came out. My father is a dentist and we got some samples to try out. I had tried the Oral-B rotary style brushes and I feel that the sonicare is superior and the brush heads seem to last longer. Plus, with rotary there is more friction which, if you overbrush, can wear down your enamel and possibly hurt your gums (many people do not know that you can overbrush).
I've taken the sonicare on travel many times for weeks on end and the battery life is impressive.
Some people find it difficult to pay close to $100 for a toothbrush and then having to buy replacement brush heads at $10 a piece every 6 months.
I don't think you can afford not to use a sonicare. Your dentist will definitely be able to tell a difference.
As always, there is no substitute for flossing. When they come out with one, someone will become a multi-millionaire.
