After Flu Season, Always Change Your Toothbrush!

Following every flu season and this could include the current COVID pandemic, if you are anything like me, you do the normal routine: Wash blankets, pillow cases, sheets and basically disinfect the whole house. Especially if you or someone in your household has been ill.

However, one thing that often gets overlooked is your toothbrush! Even if you didn't have the flu, you want to make sure you replace it. Airborne viral bacteria can attach to basically anything, including your toothbrush and theoretically it can transfer to your body when you brush your teeth.

There is a common misconception that toothbrush bacteria is harmless. Afterall, you are the only one who uses it, right?  Well, consider this: The bristles on the toothbrush are tall and there are many areas for bacteria to hide. The toothpaste does not clean or disinfect the brush. Soaking it in mouthwash from time to time can be helpful, and a good rinsing every time you brush is a good practice.  Still, the ADA recommends that you replace your toothbrush after a viral or bacterial illness or every 3 months to prevent the spread of infection.
