An intraoral light therapy device comprising a mouthpiece that is formed in a U-shape according to a wearer’s dentition and is fit in an oral cavity, and a light source that is disposed in the mouthpiece and is provided with a plurality of light emitters, such that the intraoral light therapy device irradiates light to the wearer’s gums from the light emitters,

wherein the mouthpiece comprises:
a bite tray formed in a U-shape according to the wearer’s dentition and bitten by the dentition of the wearer’s upper and lower jaws;
a front flange formed vertically along an outer edge of the bite tray and facing outer surfaces of the wearer’s upper and lower gums;
and
a rear flange formed vertically along an inner edge of the bite tray and facing inner surfaces of the wearer’s upper and lower gums;
and
wherein the front and rear flanges are optically transparent, and the light source is disposed to be configured to irradiate light from an inner peripheral surface of the front flange and/or an outer peripheral surface of the rear flange,
wherein an upper edge portion of the front flange is formed with a recess portion at which the wearer’s upper labial frenulum is located, and a lower edge portion of the front flange is formed with a recess portion at which the wearer’s lower labial frenulum is located, and
