How to use

Attach the brush head to the handle, select a mode and intensity, and place the brush at a 45° angle to the gum line. Guide the brush slowly across each tooth surface, allowing the sonic action to clean; do not scrub. Follow the integrated timer and app prompts to ensure two minutes of brushing and to cover all quadrants evenly. Charge the handle as needed using the supplied charger.

Recommendations

Use twice daily for optimal results and follow app guidance for personalised coaching. Replace the brush head every three months or sooner if bristles are frayed. Consult your dental professional for specific oral health concerns.
