Since the outbreak of COVID-19, everyone is doing their utmost to keep their homes clean and germ-free. One place that many of us forget to sanitize, though, is our toothbrush. Your toothbrush bristles are exposed to leftover food particles in your mouth twice every day (or at least, they should be), so they can quickly become a breeding ground for harmful bacteria. As a result, it’s important that you learn how to properly disinfect your toothbrush. For this reason, a dentist has written this blog on how to give your toothbrush a much-needed cleaning.
Caring for Your Toothbrush
Ideally, you should clean your toothbrush every time you use it. According to the American Dental Association (ADA), microorganisms from your mouth and the surrounding environment grow on your brush bristles after you use them. The ADA suggests that you remove all food debris by thoroughly rinsing the bristles in clean water after you’re done brushing. Afterward, place it in an open holder and allow it to dry without coming into contact with any other brushes. Don’t share toothbrushes, and don’t store it in a dark, damp place like a drawer or cabinet. You should replace your brush every three months, or sooner if the bristles appear worn or frayed.
Disinfecting Your Toothbrush Bristles
If you think you may have been exposed to COVID-19, or any type of infection, then it’s a good idea to give your toothbrush a complete disinfection. Otherwise, you could infect yourself with the germs you were exposed to that day. Here are some tips to deep clean your toothbrush:
- Swish the bristles in antibacterial mouthwash for 30 seconds.
- Soak the brush in a solution of two teaspoons of baking soda in a cup of water.
- Once a week, soak the bristles in vinegar overnight.
- Dissolve a denture or retainer cleaning tablet as directed on the label and soak the bristles in the mixture.
Never soak your toothbrush in mouthwash for longer than 15 minutes, and never reuse any of the mouthwash to clean your mouth. It’s also not recommended to place your toothbrush in a microwave or dishwasher. Heating the plastic on the brush could damage it and render it less effective.
It’s not usually necessary to throw out your toothbrush after you have been sick, even with COVID-19. Just make sure to follow the advice listed above on how to thoroughly disinfect your toothbrush, and your oral health should stay in great shape.
