Do I Need to Replace a Toothbrush After Illness?
Cold and flu season is here, unfortunately. While we don’t wish getting sick on anyone, it’s important to make sure you take the time to sanitize your dental care tools after the illness has passed. Since your toothbrush plays a big role in your oral health, knowing when to replace it after an illness can help keep your mouth clean and your family healthier.
Should You Replace a Toothbrush After Being Sick?
In most cases, yes. Viruses and bacteria can stick to the bristles of your toothbrush. While the risk of re-infection is usually low, especially once your immune system has already fought off the illness, replacing your toothbrush can give you peace of mind. It is a simple step that can help prevent spreading germs to others in your household.
When to Definitely Replace Your Toothbrush
Here are a few situations where it is a good idea to start fresh with a new toothbrush:
After the flu, strep throat, or a bad cold
If you have had a contagious infection that spreads easily in families
When your child has been sick and might accidentally share toothbrushes or leave them touching others in the holder
Everyday Toothbrush Replacement Rules
Even if you are not sick, toothbrushes do not last forever. Dentists recommend:
Replacing your toothbrush every 3 to 4 months
Checking the bristles regularly, and swapping it out sooner if they are frayed or bent
Switching to a new toothbrush after dental procedures if your dentist recommends it
Tips to Keep Toothbrushes Clean Year-Round
A few simple habits can keep germs from building up on toothbrushes:
Rinse your toothbrush thoroughly with water after each use
Store it upright so it can air dry completely
Avoid storing toothbrushes in closed containers where moisture lingers
Keep family toothbrushes separate to prevent cross-contamination
The Bottom Line
If you or your child has been sick, replacing your toothbrush is a quick and easy way to keep everyone’s oral care routine healthy. Along with regular brushing, flossing, and checkups, this small habit can make a big difference in keeping smiles clean and protected.
