Toothbrushes eventually wear out and need to be replaced. Numerous studies show that, after three months of normal wear and tear, the nylon bristles in toothbrushes are a good deal less effective at removing plaque from tooth surfaces and gums than new ones. To be effective, bristles must be able to make their way into the crevices that harbor the bacteria that are constantly forming to pose a threat to tooth enamel and gums. In addition to replacing toothbrushes, it is also important to allow them to air dry after use since wet bristles are breeding grounds for unhealthy bacteria and fungi. Be sure to replace toothbrushes after a bout with a common cold to reduce the risk of reinfection.
When you travel, a plastic toothbrush case can protect the brush bristles from flattening in your traveling kit. After you brush your teeth, let your toothbrush dry in the open air rather than putting it back in your plastic case.

P.S. If you need a reminder to replace your toothbrush regularly, purchase one with bristles that change color as they degrade.
