You should change your toothbrush every three to four months. This recommendation applies to both manual toothbrushes and electric toothbrush heads, as worn or frayed bristles become less effective at cleaning teeth and can harbor bacteria
. Additionally, you should replace your toothbrush sooner if:
- You have been sick, to avoid re-infection or spreading germs
- The bristles look frayed, bent, or worn out before the three-month mark
- You notice buildup or stains at the base of the bristles
Maintaining your toothbrush by rinsing it thoroughly after use and storing it upright to air dry helps keep it clean, but regular replacement is still essential for optimal oral health
. In summary, changing your toothbrush every three to four months, or sooner if it shows signs of wear or after illness, ensures effective cleaning and reduces the risk of plaque buildup, tooth decay, gum disease, and infections.
