How Often Should I Replace My Toothbrush?

Everyone knows that brushing your teeth is a vitally important part of oral hygiene, but how much do you know about the brush you’re using?  Many people use toothbrushes for far longer than they should.  In most cases they should be replaced every 3-4 months, or as soon as you notice the bristles starting to fray or splay outward.  Even if there’s no visible wear and tear, studies show that after three months, toothbrushes become less effective at removing plaque.

It’s also a good idea to get a new toothbrush after you recover from an illness like the flu. Viruses and bacteria may remain in the bristles and could cause re-infection.  Even if you haven’t been sick, it’s possible for germs to thrive if the toothbrush isn’t rinsed thoroughly and then allowed to air dry.

And of course if your cat gets ahold of your toothbrush, it’s time for a new one!
