How often should I replace the brush head?

It is recommended to replace your Philips Sonicare brush head approximately every three months. This timeframe ensures optimal cleaning efficiency and effectiveness. Over time, brush heads become less effective due to wear and tear, resulting in reduced plaque removal and a less thorough clean. The reminder bristles on the brush head also fade to indicate when it's time to replace it. It is important to note that individual usage habits and oral health conditions may vary, affecting the lifespan of your brush head. Regularly inspect the bristles for signs of fraying or deterioration, as these indications may necessitate an earlier replacement. By maintaining a consistent replacement schedule, you can maintain excellent oral hygiene and achieve the best results from your Philips Sonicare electric toothbrush.
