When Should I Change My Toothbrush?

Published on February 20th, 2019 by Michael C. Griffin, D.M.D.

It’s easy to tell when you need new shoes or you’ve worn out your favorite sweater, but do you know how often you should change your toothbrush? Well, there’s no cut and dry answer. According to our dentist in Wrigleyville , it depends on your usage, health, and personal preferences. Before you reach for your toothbrush tonight, consider whether it’s time to throw out your old toothbrush and spring for a new one.


It’s typically recommended that you replace your toothbrush every three to four months. If you’ve recently been sick, you might want to get a new one sooner. You may be unsure how long it’s been, but don’t fret – when in doubt, check the bristles.

Maintaining Your Toothbrush

No one wants to spend more money than they have to on toothbrushes, so we have a few tips to keep your toothbrush fresh for longer. No matter what, whether it’s electric or manual, always keep your toothbrush clean! The American Dental Association suggests rinsing it off with tap water after you finish your nightly dental care routine in order to wash away leftover toothpaste and saliva. When you store your toothbrush, make sure it’s in an upright position so the bristles can air dry. You want to avoid storing it in a closed container, as bacteria will build without airflow.

So, how often should you change your toothbrush? Get in the habit of buying a new one several times a year, and keep the one you’re using clean and sanitary before the bristles start to fray. If you’re in need of a few more pointers, contact our dentist in Wrigleyville.
