When Should You Replace Your Toothbrush or Brush Head?

Toothbrushes aren't meant to last forever. When exactly is it time to replace them and where should they be stored?

The toothbrush is essential to maintaining proper oral hygiene and serves as a key tool in prevention against plaque buildup and cavities. But let’s face it; a toothbrush isn’t built to last forever. After multiple uses, the bristles will begin to fray and there’s nothing worse than brushing your teeth with a frayed toothbrush. Well, actually, not brushing your teeth at all would be worse, but nonetheless, frayed bristles will not properly clean your teeth and lead to periodontal issues down the road.


So the question arises, when should you replace your toothbrush or brush head? Totowa Dental Center recommends replacing your toothbrush or brush head every three months. However there are some instances when we recommend changing your brush before three months:

  • If your bristles start to fray before the 3 month mark

  • When you are sick or not feeling well - Toothbrush bristles do not kill bacteria in the mouth, protect you against disease or prevent you from getting sick

While on the subject of changing your toothbrush, where do you keep yours?

Most people keep their toothbrush next to the sink or in a cup on a vanity near the toilet. Did you know that storing your toothbrush within a five foot radius of your toilet will result in some rather unpleasant bacteria on it? If you go to the bathroom, flush with the lid up, and then go brush your teeth, you’re basically brushing with…well, we’re sure you get the picture.

Follow these tips from the American Dental Association to prolong the life of your toothbrush and keep bacteria where it belongs….not in your mouth!

  • Do not share toothbrushes.Sharing a toothbrush could result in an exchange of body fluids and/or microorganisms between the users of the toothbrush, placing the individuals involved at an increased risk for infections.

  • Thoroughly rinse toothbrushes with tap water after brushing to remove any remaining toothpaste and debris.Store the brush in an upright position if possible and allow the toothbrush to air-dry until used again. If more than one brush is stored in the same holder or area, keep the brushes separated to prevent cross-contamination.

  • Do not routinely cover toothbrushes or store them in closed containers. A moist environment such as a closed container is more conducive to the growth of microorganisms than the open air.
