Some toothbrushes have filaments that are all the same height; others have them at different heights. Some are grouped in patterns while others form an even grid overall. If your teeth feel clean with the one you choose, there is no need to change it. Whatever you choose make sure you replace your brush when the bristles look shaggy, bent or uneven. Every three months is what the experts recommend.
The handles of many toothbrushes are ergonomically designed to help us reach right into the back while maintaining the correct brush position. Some handles have a non-slip surface that is good for children and older people who may have arthritis. People with small mouths should probably choose a toothbrush with a smaller head. Brushing your teeth should never feel uncomfortable.
