A toothbrush should be replaced every three or four months, or sooner if the bristles become frayed. A worn toothbrush does not do a good job of cleaning your teeth.
Children should have a child-sized toothbrush for ease of use. The variety of colors and designs can provide extra fun and motivation to keep children brushing.
People who have hand, arm, or shoulder problems that limit movement may find that a powered toothbrush is the best choice for them. Or they may find that by modifying a manual toothbrush, they can brush without assistance from others. A few tips:
- Attach the toothbrush handle to the hand with a wide elastic band.
- Enlarge the toothbrush handle with a sponge, rubber ball, or bicycle handle grip.
- Lengthen the toothbrush handle with a piece of wood or plastic, such as a ruler or wooden tongue depressor.
- Bend the toothbrush handle. To do this, try running hot water over the handle (not the head) of the brush to soften it.
