How to use

Attach a compatible brush head and select a suitable cleaning mode using the 3D touch controls. Apply a pea-sized amount of toothpaste to the brush head, place the brush against teeth at a slight angle, and move it slowly from tooth to tooth. Follow the integrated timer prompts to ensure each quadrant of the mouth receives adequate attention. After brushing, rinse the brush head under running water and allow it to dry. Place the handle on the wireless charger when the battery needs recharging.

Recommendations

Use the whitening mode for short-term polishing (avoid excessive force), and switch to massage mode for gentle gum stimulation. Replace brush heads according to manufacturer guidelines or sooner if bristles show wear. Do not submerge the handle beyond recommended depths despite IPX7 protection; rinse and dry after use. Consult a dental professional for personalized advice on mode selection and brushing frequency.
