Do You Disinfect Your Toothbrush?
Categories: Dental Health

Think about it… Our mouths contain lots of bacteria and now imagine all those bacteria ‘sitting’ on your toothbrush…

You can think: But I am rinsing my toothbrush with water after every use. Yes, some of the bacteria and food debris will go down the drain, but far too many of them remain on our toothbrushes. Simple rinsing with water will not get rid of it.

Also bathrooms are the most ideal environments for bacteria, they are warm and moist and some of you probably put caps on your toothbrushes? If you are one of those people then DON’T! Bacteria will LOVE that warm and cosy environment while it sits all day in the bathroom! For more advice on maintaining oral health, check out our dental hygiene tips for healthy teeth and gums.

BUT do not worry, the solution is simple. You can sanitise it and enjoy squeaky clean, bacteria free toothbrush bristles.

Here are a few ways to do that:

  • Soak your toothbrush in antibacterial mouthwash. It can be simple and cheap Chlorhexidine Mouthwash form your pharmacy or Corsodyl or Curacept.  Pour a little bit in a cup put you toothbrush head down soaking overnight or while you’re not using it during the day. Remember to rinse thoroughly before using it again





  • Boil your toothbrush for about 3 minutes.  Although it is hard on your toothbrush, boiling water will kill most germs. You can also boil some water and pour it onto toothbrush bristles.
  • Use Retainer Brite tablets – although used for cleaning and sanitising retainers and dentures can be easily used to disinfect your toothbrush.  Dissolve one tablet and dip your toothbrush head in it.





  • Purchase a UV toothbrush sanitiser. These gadgets work by combining steam with dry heat to sanitiser  your toothbrush. These can be an expensive option unless your toothbrush came with one.

Worth remembering: If you are sick or you are at higher risk of infection remember to disinfect your toothbrush and replace your toothbrush with the brand new one or every 3 months.
