How to disinfect your Toothbrush

July 27, 2022

Brushing your teeth is an important part of your daily routine.  Have you ever thought about how you could be doing more harm than good with a germ-riddled toothbrush?  We are so focused on the toothpaste we brush our teeth with that we will sometimes neglect that our toothbrushes need some care too.  Our mouth is home to millions of germs, including those living in the plaque on our teeth, so it’s no surprise that these germs can collect on your toothbrush. In the article, we will give you ways to disinfect your toothbrush.  It is always important to follow your manufacturing guidelines for cleaning your toothbrushes as well, especially if it is electric.

Some simple ways how to disinfect your toothbrush

(Please note: that some of these methods can ruin a toothbrush sometimes because of all the different materials toothbrushes are made out of.  Please use it at your own risk.)

  • Hydrogen Peroxide – Soak your toothbrush weekly in a container filled with hydrogen peroxide. It’s best to let it soak overnight. Be sure to rinse before using.
  • Antibacterial Mouthwash – Place your toothbrush in a cap full of antibacterial mouthwash (ideally one containing alcohol for more germ-killing action) for two minutes to help break down food and bacteria particles. Rinse out and allow to dry before using.
  • Soak in Rubbing Alcohol – You can give your brush a quick soak in a bit of rubbing alcohol. However, be sure to rinse with clean water thoroughly. The taste and smell of rubbing alcohol might make your child’s dental care routine unpleasant.
  • Use Baking Soda – Stir two teaspoons of baking soda into one cup of water, then soak your toothbrush for one to two minutes. Rinse with cold water and allow it to dry completely before using it.
  • Use your Dishwasher – One of the quicker and easier ways to disinfect your toothbrush is to place your toothbrush on the top rack or in your utensil tray.  Make sure that you are only placing the head of the toothbrush when it comes to electric toothbrushes.
  • Denture Cleaner – WebMd recommends putting your toothbrush inside a cup of water, then adding a denture-cleaning tablet to help break down food deposits and eliminate bacteria particles. Rinse out and allow to dry before using.
  • UV Toothbrush Cleaner – Do you like the idea of a high-tech and easy UV light toothbrush sterilizer?  Research does show that these products do kill bacteria, but they are not effective at removing all the bacteria from a toothbrush. Also, the UV light tends to break down plastic bristles, so be sure to check your child’s toothbrush regularly for wear.
  • Boiling Water – Perhaps the oldest method of toothbrush sanitation is boiling water. Bring water to a rolling boil before adding your toothbrush and then set a timer for 3 minutes. Carefully remove your toothbrush from the water and let it cool down. Be warned that the hot water used in this method can be damaging to your toothbrush so be sure to inspect it for signs of damage before use.

Do Not Share your toothbrush with anyone

You may sometimes get tempted to lend a toothbrush to a family member or friend? Here at Smiles of Round Lake Dentist, we say “Don’t”.

When you share your Toothbrush, you transfer saliva and bacteria — even the bad kind that can cause tooth decay. “ Tooth decay is the destruction of your tooth enamel, the hard, outer layer of your teeth.” This should be one more reason not to share your toothbrush.

Sanitize your toothbrush for at least 20 minutes, every 3 days. The ADA recommends that you should replace your toothbrush every 3 to 4 months or sooner
