Sanitizing Your Toothbrush Only Takes a Minute Each Day

Posted on 5/20/2017 by Boeckel

You use your toothbrush every day, twice a day. It cleans your teeth of food debris, plaque and harmful oral bacteria.

In order for a toothbrush to remain effective, it should be replaced approximately every three months.

Sure, you rinse your toothbrush off in between uses and place it to air dry, but many germs can still remain on the bristles.

Bacteria multiply rapidly, which means the next time you use your toothbrush, there may be a significantly larger number of bacteria on the bristles than when you left it. Sanitizing your toothbrush will help to eliminate these bacteria, and it only takes a minute of your time.

Use Mouthwash

Antibacterial mouthwashes work to kill germs in your mouth. It can also kill those same germs on your toothbrush. Simply set your toothbrush in a cup of mouthwash so that the head is completely submerged and go about the rest of your morning routine. Before you leave the bathroom, remove the toothbrush, rinse and store. Alternatively, you can soak your toothbrush before you brush, so you have a nice, added boost of freshness.


Rubbing alcohol is quite effective at sanitizing a toothbrush. It has a higher alcohol content than mouthwashes that contain alcohol, and therefore can work quite quickly. You should still leave your toothbrush submerged for at least a minute. After you remove it, shake off the excess and leave it to air dry. If you plan to use it, rinse it off first. If you don't have rubbing alcohol, you can also use hydrogen peroxide.

Boiling Water
Boil water on the stove. When you have a rolling boil, dip the head of your toothbrush in and hold it for 30 seconds to a minute. This method is especially effective if you have an illness, and can help you to get better faster.

Other Methods
There are other methods for sanitizing your toothbrush, but they take longer than a minute, and aren't done every day. One such popular method is the dishwasher.

If you want to use the dishwasher, just make sure the heat settings aren't too high. If you don't need your toothbrush right away, pop it in when you are going to run your dishwasher and take care of two tasks at once.

Sanitizing your toothbrush every day will help to kill harmful bacteria, ensuring that your bristles are clean every time you use it. For more information on the care of your toothbrush, be sure to contact our office.
