How often should you change your toothbrush?

A toothbrush has a lifespan, and changing it as needed is important to maintaining good oral hygiene. Here are a few signs that indicate you need to change your toothbrush:

  • After three months of use: Research shows that after three months, the bristles wear out and become less effective. It is recommended to change your toothbrush every three months.
  • Bristles are sticking out in different directions: If the bristles start to look disorganized and stick out in different directions, this indicates that the brush is losing effectiveness. This can lead to unsatisfactory cleaning and even damage to the gums.
  • Illness or cold: After illness, it is recommended to change your toothbrush to prevent re-infection. Bacteria hiding in the brush can become a source of secondary infection.

Changing your toothbrush regularly helps maintain optimal oral health and prevents possible problems with the health of your gums and teeth.
