An intraoral phototherapy device is provided that improves illumination of a tonsillar region of the oral cavity. Oral tissue illumination is particularly difficult in the back of the throat. The intraoral phototherapy device improves illumination of these tissues by using a breathing tube to improve patient breathing. The breathing tube allows a patient to breathe through their mouth, which opens up the tonsillar region of the oral cavity. Additionally, objects contacting near the back of the throat often induce a gagging reflex. This gagging reflex shortens the time available to perform phototherapy, making it difficult for phototherapy to be delivered to the back of the throat. The intraoral phototherapy device may reduce the gagging reflex by contacting the hard palate of the oral cavity with a dorsal fin, such that the intraoral phototherapy device does not make contact further back in the oral cavity.
