The American Dental Association recommends cleaning your toothbrush once every week, if not more. Cleaning your toothbrush will keep strains of viruses and bacteria from re-entering your mouth the next time you brush. This is why it’s especially important to disinfect toothbrushes when you’re sick with the cold or flu.
Ultimately, it comes down to finding your ideal method or what is most convenient for you. The following ideas are both easy and effective at killing germs that can spread bacteria and illness.
Soak in Mouthwash. Soaking your toothbrush in an antibacterial mouthwash is an easy and effective way to get it clean. Simply fill a cup with mouthwash and submerge your toothbrush in the solution, head down. Allow it to soak for at least four hours and rinse the brush thoroughly before using.
Vinegar Soak. Using white distilled vinegar is one of the best ways to clean a toothbrush without using specialty cleaners. Place your toothbrush head down into a cup filled with white distilled vinegar and let it soak for at least eight hours. Rinse well.
Boil It. If you need to sanitize your toothbrush and are also on a time crunch, boiling it could be your best option. Simply boil water in a pot on the stove and then soak your toothbrush in the water for just 10 minutes. Occasionally stir the toothbrush around with a spoon to ensure your entire toothbrush gets clean.
Use Hydrogen Peroxide. If you have hydrogen peroxide on hand, it may be your key to a clean toothbrush. Allow your toothbrush to soak in a cup of hydrogen peroxide (head down) for six hours for maximum sanitation benefits.
