Most dentists agree you should change your toothbrush every 3 months. Studies show that after three months of normal wear and tear, the brush becomes less and less effective at removing plaque from teeth and gums compared to new ones. The bristles break down and loose their effectiveness as well
Important Tooth brush care:
- Let it dry out between uses. Toothbrushes can be breeding grounds for germs, fungus and bacteria, which after a while can build up to significant levels. After using your toothbrush, shake it vigorously under tap water and store it in an upright position so that it can air out.
- Keep your toothbrush from touching others when it is stored. A standard toothbrush holder with slots for several brushes to hang upright is a worthwhile investment in your family's health. This will bring down the chances of transmitting cold and flu germs.
- It is also important to change toothbrushes after you've had a cold, the flu, a mouth infection or a sore throat. That's because germs can hide in toothbrush bristles and lead to reinfection.
