To protect the oral mucous membrane from the chemical reaction of the toothpaste and to optimize the pharmacological action of the paste during brushing, the "paste discharge nozzle combined with advanced sensing technology" discharge the paste and apply it onto the teeth according to the movement of the bristle of the toothbrush in the mouth, perceiving the brushing and rinsing step of tooth brushing, and selectively applies the paste only in the required process.

It automatically controls the discharge of toothpaste by itself to optimize the pharmacological action of the toothpaste.

Sensor-B is a smart toothbrush designed so that the toothpaste charged to the handle is dispensed according to the movement of the bristle during brushing and applied evenly onto the teeth and works directly on each part immediately on being discharged so that the teeth can be brushed with the paste in a hygeinic manner.

It is an "intelligent toothbrush" that perceives the brushing part of the teeth and brushing stage of tooth brushing and selectively dispenses the paste only in the required process to prevent the damage caused by overuse of the paste.

It is an eco-friendly smart toothbrush for next-generation that automatically controls the discharge of toothpaste to optimize the pharmacological action of the paste to prevent damage caused by misuse or abuse of toothpaste, individually charged toothpaste to the handle, and can be used semi-permanent if only the head is replaced.
