Your toothbrush is your most important tool for keeping your mouth healthy. We know you’ve gotten one if you’ve been maintaining your appointments at Dr. Suzanne Haeri’s South Carthay dental office, but we hope you’re replacing it in between visits. Toothbrushes get less effective as they become worn, so to make sure our patients are taking good care of themselves, we wanted to say a bit about toothbrush maintenance.

It usually takes about three to four months for a toothbrush’s bristles to become too matted to be of use, although you’ll have to use your own judgment if you think you’re wearing them out sooner. You should certainly replace the toothbrush if the bristles are crushed down sideways. You should also be letting your toothbrush dry in the open air while upright, since putting it in a closed case will allow fungus to grow on it. There’s no evidence that free-floating bacteria that land on a toothbrush will harm the user, but washing the toothbrush with hot water before and after using it will help prevent bacterial build-up.

Some dental companies manufacture specialized tools for cleaning toothbrushes, including their own electric toothbrush heads. But you should never clean a toothbrush by putting it in a dishwasher or microwave, or you risk melting it. Different people’s toothbrushes should be kept from touching each other so that bacteria won’t migrate between people. It’s also a good idea to maintain separate toothbrushes for natural teeth and dentures, although that’s more to protect the dentures from being scratched by toothpaste intended for harder, natural teeth. And remember that only soft-bristled toothbrushes should be used for dental hygiene.
