Can Germs Live on my Toothbrush?

Chances are you would be disgusted at the thought of leaving your eating utensils on your bathroom counter exposed to germs, and never washing them but continuing to eat with them. This is essentially what you’re doing if you leave your toothbrush sitting out, and never sanitize or change it. Let’s talk about how to keep your toothbrush from being a germ-infested threat to your health.

Your toothbrush can be contaminated by bacteria, saliva, blood, and food particles with each use. Even after you rinse it with water, your toothbrush may appear clean but germs linger on the bristles. Some of the sources of bacteria on your toothbrush include:

  • Your mouth, which transfers germs to your toothbrush during use.
  • The environment, because bathrooms are often the most contaminated room in your house.
  • The packaging, since toothbrushes aren’t sold in sterile packages they can arrive with germs already on them.

Here are some tips to guard your toothbrush from germs:

  • Before and after you brush your teeth, wash your hands to get rid of germs.
  • Rinse your toothbrush well with water, and then allow it to air dry.
  • Store the toothbrush upright so that water can drain from it while drying.
  • Consider storing your toothbrush in a dry area outside of the bathroom, away from humidity and toilet spray
  • Replace your toothbrush every 3-4 months, or more often if you notice worn bristles.
  • Do not share your toothbrush with anyone.
  • Do not soak your toothbrush in disinfectant or mouthwash, which can lead to cross contamination
  • Do not bother microwaving your toothbrush or running it in the dishwasher, because these tactics may damage your brush.
