You should replace your toothbrush every three to four months. This timeframe ensures the bristles remain effective at cleaning your teeth and helps prevent bacterial buildup that can harm your oral health
. Additionally, you should replace your toothbrush sooner if:
- The bristles become frayed, bent, or worn out, as worn bristles lose cleaning effectiveness
- You have been sick, especially with respiratory infections, to avoid reinfection and bacterial contamination
- Your toothbrush develops an unusual odor or if someone else accidentally uses it
- You have had dental procedures or oral infections
Proper toothbrush care, such as rinsing thoroughly after use and storing upright in a dry place, can help maintain its effectiveness between replacements
. In summary, the standard recommendation is to change your toothbrush every 3-4 months or sooner if signs of wear or illness occur to maintain optimal oral hygiene and prevent dental problems.
