Do Toothbrush Sanitizers Work?
With so many products on the market, how do we know if toothbrush sanitizers actually help rid our toothbrushes of bacteria? Is it just a marketing ploy, or are sanitizers truly effective?
Germs are Transferred from Mouth to Toothbrush
Millions of germs live in your mouth and get transferred to your toothbrush every time you brush. We now know that plaque and gum disease can lead to additional health-related issues. It is this fear that drives people to look for ways to keep their toothbrush free from germs. Are sanitizers the way to go?
Sanitizer versus Sterilizer
First, it is important to note that the word sanitizer refers to a device that kills most of the microorganisms. A sterilizer kills all the microorganisms. Sanitizers work by exposing the toothbrush to UV light, which kills most microorganisms while the heat dries the toothbrush. Typically, there is a cover over the toothbrush, protecting it from exposure to airborne microorganisms. Always look for products that are approved and regulated by the FDA to ensure that you get an effective machine.
Study on Toothbrush Sanitizers
Although sanitizers have become very popular, they are costly, running up to $80. To date, there has been no conclusive study or evidence indicating that sanitizers are the most effective way to fight germs on your toothbrush. A 2006 study done by first-year dental students at Creighton University School of Dentistry in Omaha, Nebraska concluded that immersing your toothbrush in an antibacterial rinse was just as efficient as a sanitizer in keeping bacteria off of your toothbrush.
Ways to Clean Your Toothbrush
Indeed, you need to keep your toothbrush clean. However, you have options in how you can do that. You can either use a commercial toothbrush sanitizer, or opt to use one of these other suggestions:
• Rinse and air dry your toothbrush, making sure it avoids other brushes.
• Soak your toothbrush in an antiseptic mouthwash.
• Boil or put your toothbrush in the dishwasher (this can wear out bristles faster).
• Microwave your toothbrush on high for 10 seconds.
ADA Recommendation
Whatever you decide, the American Dental Association (ADA) recommends that you still replace your toothbrush every three months or after an illness, and keep your toothbrush upright and away from other bathroom items.
