Brush Your Teeth (continued)
Choose your toothbrush
Dental researchers have discovered that toothbrushes with soft, nylon or polyester bristles with rounded tops do the best job of brushing teeth. Stiff bristles with sharp edges can damage teeth and gums, while natural bristles are porous and can harbor bacteria.
Your toothbrush should be easy to handle, and its head should be small enough to fit into your mouth easily. The modern trend in toothbrushes is toward smaller heads that can be used more precisely around gumlines and between teeth.
If the bristles on your toothbrush no longer stick up straight but rather flare to the side, it's time for a new one. Dental experts say it's a good idea to replace your toothbrush every two to three months.
