How to Disinfect a Toothbrush?

You should get a new toothbrush every three to six months. You can disinfect your toothbrush by letting it soak for a bit in a mixture of water with a cap full of peroxide. If you don’t have that, you can try just a little bit, maybe a teaspoon of bleach in a glass of water. Be sure to rinse the toothbrush well before using.
