The Sonicare 9900 Prestige, DiamondClean Smart and FlexCare Platinum are equipped with the brushing guidance feature. It is designed to detect and promote an equal amount of brushing inside and outside your teeth.
The brushing guidance starts from the upper-right teeth. Continue to follow the brushing pattern shown in the app. Ensure that you follow this brushing pattern as the app cannot locate the position of your toothbrush.
Once finished, the app will give you brushing insights that you can use to improve and maintain your oral health.
Note: Our app is updated regularly. For the best experience, ensure that you download the latest version of the app.
