How often should you replace a toothbrush?

Every 3 to 4 months, sooner if bristles fray.

  1. Every 3 to 4 months ✔
  2. Once a year
  3. Only when you lose it

Why: The American Dental Association says replace a toothbrush every 3 to 4 months, or sooner if bristles look matted. Soft bristles and a gentle hand are kinder to gums.

Huh, didn't know that: Brush twice a day for two minutes. The catalog already covers toothpaste amount.
