How Often Should You Change Your Toothbrush?

Replace toothbrushes every 3 to 4 months. Consider getting a new toothbrush sooner if you have been sick, especially if the toothbrush is stored close to other toothbrushes. When in doubt, look at the bristles. If they are frayed, they won't clean teeth as thoroughly. Because children often brush more rigorously than adults, they may need their toothbrushes replaced more often.

There are two styles of toothbrushes to consider: manual and electric. Choose what feels comfortable and makes you want to brush your teeth regularly. A manual toothbrush is portable and ready to use every time you need it. It makes no noise, and you will have complete control over the pressure it puts on your teeth and gums.

An electric toothbrush requires charging and is a bit more cumbersome to take along when travelling. However, the rotating movement of the bristles makes it easier to clean between teeth and at the gum line. Many electric toothbrushes have built-in sensors to make sure you brush long enough and don't press too hard.

No matter which type of toothbrush you use, keep it clean. The American Dental Association suggest to rinse the toothbrush thoroughly after each use to remove any remaining paste and debris. Store toothbrushes in an upright position after use and allow them to air dry. Storing a moist toothbrush in a closed container promotes microbial growth more so than leaving it exposed to the open air.

Storing a toothbrush in a closed container can cause bacteria to build up, so it's best to let the bristles of the toothbrush fully dry between each usage. If you're travelling, consider using disposable toothbrushes during the trip.

How often should you change your toothbrush? Get into the habit of buying new toothbrushes for everyone in the family several times per year. How often you change your toothbrush depends on several factors, but it's best to always have a new, fresh toothbrush waiting in the bathroom cabinet for each family member.
