How often do I need to replace the brush head?

Oral B Toothbrush typically recommends replacing the brush head every three to four months to ensure optimal cleaning performance. However, if you notice that the bristles are frayed or worn down before that time frame, it is a good idea to replace the brush head sooner. Using a worn brush head can lead to less effective plaque removal and may not provide the best gum care. Additionally, if the brush has been exposed to moisture or stored in a humid environment, it might be beneficial to check its condition more frequently. Users are encouraged to visit the current Oral B website for further guidance on maintaining the toothbrush and suggestions tailored to specific model features.
