Features
A function that detects excessive brushing force and alerts you. Prevents damage to gums and teeth by notifying you with light or vibration when you are brushing too hard. Protects teeth from excessive force.
This toothbrush does not include a pressure sensor, which is a significant drawback. Without this feature, users may unknowingly brush too hard, potentially damaging their gums and enamel. It's important to apply gentle pressure while brushing to avoid harm.
A function that measures brushing time and notifies you after a certain period. Encourages proper brushing by signaling when the recommended brushing time has elapsed. Helps achieve proper oral care.
The built-in 2-minute smart timer ensures users brush for the dentist-recommended time. It pauses every 30 seconds to remind you to switch brushing zones, promoting even and thorough cleaning across all quadrants of the mouth.
A function that briefly pauses or vibrates to indicate when to move to the next quadrant of your mouth. Allows even brushing of the entire mouth by dividing the mouth into four sections and notifying you when to switch sections. Reduces the risk of brushing unevenly.
The quadrant pacing function briefly pauses every 30 seconds, signaling users to move to a different quadrant of their mouth. This feature helps ensure that all areas receive equal attention, promoting a more comprehensive clean and preventing neglect of certain zones.
