How Often Should I Replace My Toothbrush?

There are two types of toothbrushes on the market today – manual and electric. While there are benefits to both, the brushes themselves can wear out and accumulate bacteria. Manual brushing enables full control from the amount of pressure and movements applied to teeth, which perhaps an electric toothbrush cannot allow because of its rapid and mechanical vibrations. The benefits of electric toothbrushes are quite obvious; when in use, the bristles are able to do more than a regular toothbrush, such as massaging gums and pulsating in between the tight cracks between our teeth, giving us that “straight-from-the-dentist” clean feeling.

Whether you prefer this modern way of dental hygiene or a more traditional, inexpensive method, our teeth still take their toll on these devices and wear them out. What’s more, some researchers show that 10 million germs can be living in our toothbrush! A toothbrush can become a breeding grounds for harmful bacteria if it is not properly stored.

For best results, most experts say to replace your toothbrush every three months (if you use an electric, that means replacing the “head”, or the attachment of the toothbrush). Children may need to replace theirs more frequently because they tend to apply more pressure when brushing. Kids may grow attached to their toothbrush (especially if it has their favorite Disney character on it!) but once the bristles start to bend outwards, dentists say the toothbrush is no longer effective, and should be thrown away.

Care of Your Toothbrush & Good Habits to Form

Because the bristles of our toothbrush wear out so quickly, the American Dental Association recommends rinsing your toothbrush under the faucet between brushings to wash away saliva and toothpaste residue, and to store it upright so the bristles can air dry. If you’re a parent that is extra cautious of bacteria, soak it in rubbing alcohol when not in use, then rinse with water thoroughly.

It can be a difficult task to keep track of how long it has been since each toothbrush in the house has been replaced, especially if you have more than one kid! But remember that your child will receive a new brush with each dentist visit, and these visits occur (at the very least) every 6 months for cleaning. That means you only have to replace it once again, somewhere along the midpoint, between each visit.

*Tip: Instead of remembering to put them on the shopping list every so often, keep your bathroom cupboard or closet stocked with unopened toothbrushes. (Many stores have value packs you can purchase which contain several in a pack). This will make the transitions more convenient for you and your family.
