How to use

Apply a pea-sized amount of toothpaste to the brush head, place the brush against your teeth at a slight angle and switch the device on. Select the desired mode and intensity, then move the brush slowly from tooth to tooth, allowing the sonic action to clean surfaces. Follow the integrated timer prompts to ensure two minutes of brushing and replace brush heads according to wear or manufacturer guidance. Charge the toothbrush as needed using the provided charger to maintain optimal battery performance.

Recommendations

For best results, use the Whitening or Daily care mode for everyday cleaning and select Gum care when experiencing sensitivity. Replace brush heads every three months or sooner if bristles are worn. Consult dental professionals for personalised oral-care frequency and mode selection.
