## Abstract

An intraoral phototherapy device for simultaneously irradiating inner and outer gingiva includes a transparent shell and a circuit board. The transparent shell includes a bite portion and a stop portion. The bite portion is mounted on an inner arc surface of the stop portion. The circuit board is mounted in the bite portion, and includes first and second light emitting units. The first and the second light emitting units emit lights toward a first and a second surface of the bite portion. When a user bites the bite portion and turn on the intraoral phototherapy device, the lights emitted by the first and the second light emitting units are emitted to a gum inside and outside upper and lower jaw teeth of the user. Therefore, the intraoral phototherapy device can stimulate an affected part of a gingivitis through a photobiomodulation therapy to achieve an effect of anti-inflammation or alleviating pain.
