How to use

Attach the brush head to the handle, apply a pea‑sized amount of toothpaste, and select the Daily care mode and preferred intensity. Place the brush against your teeth at a slight angle and move it slowly from tooth to tooth, letting the sonic motion do the work. Use the SmartTimer and QuadPacer to ensure a full two‑minute cleaning with even coverage of all quadrants. Rinse the brush head after use and store the handle upright to air dry.

Recommendations

For best results, replace the brush head every three months or sooner if bristles are worn. If you experience persistent sensitivity or gum issues, consult a dental professional. Keep the handle charged to maintain consistent performance, especially before travel.
