There is no toothbrush that is best for every person. Whether you choose a powered or a non-powered toothbrush, there are few things you want to look for. Your toothbrush should be ADA certified, fit comfortably at the back of your mouth, and have a long enough handle so that you can easily reach and brush all of your teeth. Most toothbrushes will be very effective, as long as you brush properly twice a day for at least two minutes each time.
