What size should I get? Should it be manual or powered? Should the bristles be hard, soft or medium? About 70 years ago, choosing a toothbrush was easy. There was only one kind, a toothbrush with nylon bristles. Today, consumers have many different styles to choose from. But what's the best? How can we keep the cavity creeps away?
According to the American Dental Association, both manual and powered toothbrushes are good at cleaning the gunk off your teeth. In fact, various studies comparing the two indicate no difference between how they clean. However, a powered rotation oscillation toothbrush with bristles that move in circles and up and down is shown to be more effective than a manual brush [source: WebMD].
As for the size of the toothbrush head, buy what's most comfortable for you to use. Some people might have difficulty maneuvering a large-headed brush. The same holds true for bristle type. Just look for the ADA symbol on the toothbrush package and brush away [source: American Dental Association].
