My son has a virus. I’m trying to figure out if I should throw out his tooth brush now or after he is better from the virus. Is there a best practice for this type of situation?

Dear Lindsey,
I am very glad you wrote. Sorry about your son’s illness. It is never fun when our children are sick. The above picture was taken at a Walmart. This idea has been purported for years, even by dentists, but it is a false narrative. This was started by the toothbrush companies. While a creative way to get customers to throw out and replace their product, there is no scientific basis for what they’re saying.
In fact, I only know of one study that even investigated this issue. In 2013, a study at The University of Texas (you can read the study here) was published that showed there was no transmission of strep throat because of keeping a toothbrush.
Dr. Neil Schachter, a professor of pulmonary and critical care at New York City’s prestigious Mount Sinai School of Medicine said, “Once you’ve had a particular viral illness, you’re protected from it.” In other words, your child cannot re-infect themselves with something they already have.
What If You’re Still Worried?
You’re a mom, and very likely a good one based on your question; that means you are going to worry— a lot. If the above information has still left you with a seed of doubt, here are some options that should hopefully give you an action plan that takes away your fear and allows you to find new things to worry about.
First, you could just buy a new toothbrush. They don’t cost a lot and it won’t do any harm. You can switch it at any point. Another option is to sanitize your child’s toothbrush. You can do that with simple chlorine bleach. Just pour enough bleach into the cup to cover the head (brush portion) of the toothbrush. Let it sit there for about 5 minutes, then thoroughly rinse it off. There will be no residue or aftertaste and the toothbrush will be cleaner than when you first opened the package.
The best things you can do for your child are to get them to a pediatric dentist regularly, keep up with their oral health care at home, and limit their snacking.
