Most dentists recommend choosing a toothbrush with soft bristles that will not damage the enamel on your teeth.  Soft-bristled toothbrushes are more comfortable to use, which means you are likely to spend more time brushing your teeth, which in turn means you'll do a better job of getting them clean.

In addition, soft bristles, because they bend more easily around the ins and outs of your teeth and gums, do a better job of removing plaque-causing bacterias and food debris that  hard-bristled brushes do.

Make sure that the brush you select has a short handle that feels comfortable in your hand. Short handles allow for easier manipulation of the brush in your mouth, again making getting your teeth clean easier.

Many people find a powered toothbrush to be the best alternative. If you decide to go that route, remember to let the brush do the work. With powered brushes, simply place the brush on the first area to clean, hold it there gently but firmly, then lift it and move over to the next area.
