It’s something that’s easy to forget to do, but change your toothbrush every three to four months and your teeth will thank you for it.
The American Dental Association recommend this timeframe, but changing sooner if you’ve been sick recently or if you keep your toothbrush close to other toothbrushes. Because children tend to brush more rigorously than adults, they may need more regular changes.
If in doubt, take a look at the bristles. If they’re frayed, the toothbrush simply won’t be cleaning your teeth properly. Also, the newer your toothbrush, the more plaque it can remove, according to clinical research, so even if the bristles aren’t fraying, it’s important to make that change.
