How often should I change my toothbrush?

Tis the season… for the flu! I haven’t gotten to the point where I put on a mask every time I leave the house- but I have been known to carry a Lysol wipe for frequently touched door handles. I also seem to have developed the hand-washing habits of Lady Macbeth. Did you know that one major thing that we can do to prevent the spread of sickness is to change out your toothbrush?!

Toothbrushes do an amazing job of cleaning plaque from our teeth, but bacteria in our mouth usually remains after the bristles long after the brushing is done. In order to protect yourself against disease and prevent sickness, many dental professionals recommend not only diligent attention to oral care, but tossing your toothbrush or toothbrush head regularly! In general, the American Dental Association (ADA) recommends swapping out your brush every 3-4 months.

Stay healthy! Swap the brush.
