Believe it or not, the bacteria on your toothbrush may not be all that bad. The American Dental Association (ADA) reports that even though bacteria accumulates on your toothbrush, there is no indication that these germs negatively affect your oral or general health.
Your body is continually subject to bacteria, but it fights off infections by using passive and active mechanisms. Skin and mucous membranes are passive barriers that keep germs out of the body. If the skin or membranes become compromised, your body uses antibodies (white blood cells), as well as digestive acids and enzymes to protect you from disease. However, someone who has a compromised immune system or a disease that is transferable by blood or saliva may consider taking extra precautions to reduce bacterial contamination on their toothbrush.
You can find all kinds of gadgets and solutions that claim to sanitise or disinfect your toothbrush, but sanitising is different from sterilising. Sterilising means that all bacteria are eliminated, while sanitising means your brush won't be entirely germ-free.
The ADA explains that there isn't conclusive data on the effectiveness of disinfecting your toothbrush with solutions like antimicrobial mouthwash or hydrogen peroxide. It's important, however, to not put your toothbrush in the dishwasher or microwave, as these cleaning methods will likely damage your brush.
A toothbrush cover may seem like a good option for keeping your toothbrush clean, but the ADA notes that closed containers create a moist environment that actually promotes the growth of bacteria.
Here's a list of the ADA's toothbrush care recommendations. You may already be doing most of these things, but it's a good idea to reassess your routine once in a while.
If you are more susceptible to infections due to a systemic disease, the flu, chemotherapy or radiation treatments, taking extra safeguards to prevent bacteria exposure may be worthwhile. These individuals should replace their toothbrush more often than the usual three to four months and consider using an antimicrobial mouthwash on the brush to reduce the number of bacteria. Before trying any toothbrush sanitiser, check that product has been approved by the authorities.
Whether you're sick or healthy, wash your hands before brushing your teeth to prevent transferring germs to your mouth.
Use common sense and implement some basic hygiene routines to keep your mouth as clean as possible. Scheduling regular appointments with your dentist will also ensure your teeth stay healthy.
