How to Sterilize a Toothbrush in the Microwave. Germs that build up on your toothbrush can be a health risk to you and your family. But you don't need expensive steamers or a special toothbrush to kill these germs. All you need are a few household items and your microwave.
Check your toothbrush for metal. It's okay to use the microwave even if your toothbrush contains some metal, but that metal should be completely submerged in water while it's in the microwave.
Place your manual toothbrush in the microwave safe cup with the bristles down. Fill the cup with water until the bristles are submerged. Even when the water boils in the microwave, your toothbrush bristles should be completely under water. If you choose, you can use a large cup and sterilize all of your family's toothbrushes at one time.
Microwave on high until the water comes to a boil. Microwave times vary depending on the size of the cup and the amount of water in the cup. Allow the water to boil for one to two minutes.
Remove the cup from the microwave using the oven mitt. Allow the toothbrush to cool, and then bang it along the side of the cup to remove any excess debris that might have collected on the bristles.
Rinse your toothbrush under running water, empty the cup and repeat the above steps.
Sterilize your electric toothbrush by removing the toothbrush head and placing that in the cup.
Even though you sterilize your toothbrush, experts say you should still regularly replace it. Dentists say you should purchase a new toothbrush every three months.
