Brushing your teeth in the shower may seem like an efficient way to multitask, with about 4% of Americans already adopting this practice, according to a Delta Dental survey. But is this habit hygienic? Let’s explore the pros and cons of brushing your teeth in the shower.
The Shower-Brushing Debate
While no specific studies have been conducted on brushing teeth in the shower, research published in PNAS Nexus in November 2022 suggests that many showerheads harbor high levels of bacteria, such as Mycobacterium avium, which can cause lung infections when inhaled or swallowed.
Dr. Michael Wei, a dentist with Manhattan Cosmetic Dentist in New York City, advises against shower brushing due to the potential risk of bacteria from the showerhead ending up in your mouth. However, Dr. Richard M. Lipari, a dentist with Lipari and Mangiameli Dentistry in Chappaqua, New York, acknowledges that it can be more convenient, especially when using a WaterPik or water flosser.
Both dentists agree that leaving your toothbrush in the shower is a bad idea, as the wet environment promotes bacterial growth. They recommend storing your toothbrush in a holder or cup outside the shower.
Tips for Safe Shower-Brushing
If you decide to continue brushing your teeth in the shower, follow these guidelines to minimize risks:
- Brush your teeth before using soap, allowing you to rinse off any toothpaste or saliva residue.
- Keep a clean cup of tap water within reach for rinsing your mouth and toothbrush, avoiding potentially germ-filled shower water.
- Remember to floss after showering and ensure you’re brushing your teeth correctly.
Is Brushing Your Teeth in the Shower Really That Bad?
While brushing your teeth in the shower may expose you to bacteria that could harm your dental and overall health, if you choose to do so, it’s essential to store your toothbrush in a dry place when not in use. If you prefer to play it safe, stick to brushing at the sink, where you can better control hygiene and minimize bacterial exposure.
