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, so there is no alert if you are brushing too hard. Applying too much force can damage your gums and enamel, so be mindful of your brushing technique.
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 timer ensures you brush for the dentist-recommended 2 minutes. This helps promote proper oral care by signaling when the appropriate brushing time has elapsed, ensuring a thorough clean.
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 helps you brush evenly across all areas of your mouth. It briefly pauses to indicate when to move to the next quadrant, reducing the risk of uneven cleaning and promoting comprehensive oral hygiene.
A function that comes with multiple brush heads for different purposes such as sensitive teeth, whitening, or gum care. Can be used by multiple family members by switching brush heads, or can be switched according to oral condition and purpose. Increases versatility of the brush.
This toothbrush comes with only one brush head, limiting the ability to customize your brushing experience based on specific needs like sensitivity or whitening. Additional brush heads must be purchased separately.
A function that includes a stand for charging and storing the toothbrush. Allows easy placement of the toothbrush in the bathroom without taking up space. Also prevents the toothbrush from rolling around.
This toothbrush does not include a charging stand, which means you'll need to find a suitable place to lay it down while charging. A stand can help keep your bathroom counter more organized and prevent the toothbrush from rolling around.
A function that includes a case for carrying the toothbrush during travel or business trips. Convenient for carrying the toothbrush hygienically. Prevents damage to the toothbrush during transport.
This toothbrush does not include a travel case, which would have enhanced its portability and hygiene during travel. Without a case, it may be less convenient to carry the toothbrush hygienically and prevent damage during transport.
