How to keep your toothbrush clean?

Toothbrush clean

Keeping your toothbrush clean is neccessary because it acts as a vehicle for breeding and transmittion of various organisms present in the mouth and the surroundings.

Sources of germs on your toothbrush

Since millions of bacteria of various species including those responsible for the development of cavities (Strep. Mutans) and other diseases reside in your mouth, some of them are transferred to the toothbrush during brushing.

Another common source of germs on your toothbrushes is their storage in the bathroom. Since the bathroom is the most contaminated place in the house, it may be possible to find some germs from the environment on the brush.

How to clean your toothbrush

Rinse your brush with tap water

Rinse your tooth brush thoroughly with tap water before and after brushing to remove any remaining toothpaste, bacteria and debris.

Storage of toothbrush

  • Store the toothbrush in an upright position if possible and it to air dry until using it again. Be sure that air can fully circulate around the brush head as moisture provides breeding grounds for microorganisms.
  • Make sure to store the toothbrush such that their head shall not touch the others as it can transmit germs to others in the house. There are wide range of toothbrush holders available in the stores that have separate compartments for every brush so that toothbrush head doesn’t touch others.
  • Keep your toothbrush at least three feet from the toilet. Avoid placing it on the sink or near the toilet to avoid any splashes of dirty soapy water on the toothbrushes.

disinfection of your toothbrush

Mix 1 teaspoon of hydrogen peroxide or any mouthwash (for instance, Listerine) in a cup of water. Dip the head of your toothbrush in the solution for 10-20 mins.

It removes all the residual toothpaste, plaque, bacteria and food particles. Thoroughly rinse your toothbrush under tap water to remove all residues of peroxide and loosened particles.

White vinegar disinfection is the most effective, economical, easy to access and most appropriate for household use.

Why do your toothbrush smells bad?

If the bristles of your toothbrush are damp from your previous use, smell bad or show a black or yellow deposits, there’s a good chance that you may not be storing and keeping your toothbrush clean. You should get rid of this toothbrush and get a replacement as soon as possible.

How often should you replace your toothbrush?

The toothbrush bristles become frayed and worn with use and will be less effective at cleaning teeth. For this reason, American Dental Association recommends replacing your toothbrush every three to four months.

Check toothbrushes often for worn bristles and replace them more frequently if required.

Patients with systemic diseases, organ transplatation or chemotherapy have less ability to fight infections. These patients require periodic disinfection to keep their toothbrush clean and their frequent replacement to maintain oral hygiene. Moreover, children’s toothbrushes may need to be replaced more frequently than adults’ toothbrushes.

This should be done more often for an electric toothbrush than for a manual toothbrush because electric brushes often have shorter bristles. These short bristles tend to become worn down more quickly and need to be replaced sooner.

Several Oral-B brush heads have an indicator built-in bristles that change colour from green to yellow to signal when it’s time for a replacement.


To keep a Toothbrush clean is equally important as the oral hygiene practices because this is the device that performs the function of keeping your mouth clean and therefore its maintenance and timely replacement should not be neglected.

Toothbrush should be stored in an airy environment in toothbrush holders with seperate compartments and should be disinfected periodically with disinfectants to remove to loosen and remove all the germs and residual toothpaste.
