This toothbrush is powered by a battery, but also comes in just the same toothbrush without a battery. I have used both.

This Deep Clean Power Toothbrush is pretty heavy duty.

#1 - It cleans hard to reach places like at the very very back of my molars.
#2 - It has a Rotating Powerhead which loosens and whisks away plaque from surfaces, gum line and back teeth.
#3 - The Criss-Cross Bristles go deep between my teeth to lift out and sweep away plaque.
#4 - It even has a replaceable brush head when it only costs $7.88 at Walmart !! The brush heads come in a double pack. I like to change my toothbrush once a month, so just replacing the head each time is worth it than buying a whole new brush. I do put my old brushes in recycling, as they are a plastics product.

( A little thing I learned though, ,was if you use warm or even slightly hot water, it makes the bristles softer, so that is what I do. Also, brushing with hot water I find cleans the entire mouth better and activates the toothpaste to clean better.)
