Toothbrush bristles can breed bacteria and germs from food debris and mouth bacteria. However, your dentist can recommend simple cleaning methods each day to prevent the spread of germs and illness. Here’s a more in-depth look at the proper way to clean toothbrushes and keep them fresh. 

How to Disinfect Your Toothbrush


Germs and bacteria from mouths grow on the brush after using them. Sanitize the toothbrush with warm water or soak it in mouthwash for about 30 seconds after each use. You can also place the brush in a mixture of one cup of water and two teaspoons of baking soda. 

Other options include soaking the bristles in vinegar overnight once a week or swishing the bristles in a mixture of one cup of water and one teaspoon of 3% strength hydrogen peroxide. 

How to Keep It Clean 

Store the toothbrush away from other toothbrushes and the toilet area to prevent the spread of germs and bacteria. It’s also beneficial to use separate toothpaste to avoid cross contamination. After washing toothpaste and food debris from the brush, let it air dry in a clean area such as the sink, countertop, or medicine cabinet. Avoid using toothbrush covers when possible so that they can properly dry. Otherwise, harmful bacteria may spread within the cover.

Replace toothbrushes every three to four months, or if the bristles look worn or frayed at the edges. If you get sick with the flu, a cold, or other respiratory illness, you probably don’t have to replace it. After recovering from an illness, disinfecting them can prevent catching it again or spreading it to other family members.
