“It’s time to pay closer attention to your toothbrush,” said Singaporean doctor Samuel Chowdhury. He pointed out that many people store their toothbrushes near the toilet, which exposes the brushes to bacteria, viruses, and other contaminants.
“Did you know that when you flush the toilet, bacteria-laden droplets can spray onto nearby surfaces? If your toothbrush is drying next to the toilet, you could be brushing with more than just toothpaste,” Dr. Chowdhury warned.
Is the Expert Overstating the Issue?
He pointed to a 2015 study of dormitory residents’ toothbrushes that found traces of fecal matter on 60 percent of brushes, according to the Daily Mail.
Chowdhury said storing a toothbrush in a closed case can make the problem worse because enclosed spaces trap moisture and let bacteria multiply.
How to Keep Your Toothbrush Clean?
Dr. Chowdhury shared some simple tips for proper toothbrush care.
First, stand the toothbrush upright so water can drain freely.
Second, replace your toothbrush every three to four months.
Third, keep the toothbrush as far away from the toilet as possible. Close the lid before flushing. Keep the bathroom well ventilated.
Researchers at China University of Geosciences found that flushing releases a large number of tiny droplets into the air. Those droplets can carry bacteria such as E. coli and Staphylococcus aureus. Breathing them in can cause gastrointestinal illnesses or respiratory infections.
Study leader Wajid Ali says improving bathroom ventilation is key to reducing these risks.
