The product uses the vibration feedback principle to treat patients with bruxism in sleep, which can slow down the frequency and time of grinding teeth. The product uses the audio signal of the molar to detect the molar. When the molar occurs, the device transmits the signal to the vibration module. The vibration frequency and amplitude of the module can be controlled by the human brain without affecting the sleep quality of the patient. When the human brain feels vibration, new feedback is established to slow down the occurrence of molars.

The detection procedure and vibration intensity are evaluated through experiments.
