Do you know when to change your toothbrush? An old toothbrush is less effective at removing plaque and calculus from your teeth than a new toothbrush.

This is why the general rule supported by most dentists and toothbrush manufacturers is to change your toothbrush every 3 months. Studies show that over time the bristles wear out and break down making it much harder to properly clean in between teeth, gums, and deep grooves.

Many people believe that it is also important to change your toothbrush after being sick with the flu, a cold, strep throat, or other illness. You don’t want to risk the chance of re-infecting yourself with the germs that could be lurking on your toothbrush.

If your toothbrush still doesn’t look very worn after 3-4 months of regular usage, perhaps you are not brushing long enough each day. Set a timer to make sure you are brushing for at least 2 minutes, twice a day and be sure to use a fluoride toothpaste.

Signs that it’s Time to Change Your Toothbrush

As a quick recap, you should change your toothbrush if:

  • It has been more than 3 months since you last replaced your toothbrush
  • The bristles are worn, flat, or splayed looking
  • The line or colored indicator is faded away (this is a helpful feature on some brands of toothbrushes)
  • You have recently been sick

Other Handy Toothbrush Tips

Keep your toothbrush in fine working condition by following these simple guidelines for cleaning and storing your toothbrush:

  • Shake toothbrush vigorously under tap water after each use.
  • Make sure your toothbrush dries properly between uses.
  • Store in an upright position so that it can air out.
  • Keep your toothbrush from touching other toothbrushes in your household, to prevent the spread of germs.
  • Use a small protective case to keep your toothbrush from getting squished or flattened in your suitcase when travelling.
  • Set a reminder on your phone for when it is time to change your toothbrush so you don’t forget.

If your tooth brush is too hard it can also cause bleeding gums indicating you should change to a toothbrush with softer bristles.
