Abstract

An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises: a first light emitting surface configured to emit light onto a user's maxillary teeth, the first light emitting surface having a concave curvature; a second light emitting surface configured to emit light onto a user's mandibular teeth, the second light emitting surface having a concave curvature; the first and second light emitting surface located on opposite sides of a horizontal reference plane; the first light emitting surface inclined so that a first acute angle is formed between with the first light emitting surface and the horizontal reference plane; and the second light emitting surface inclined so that a second acute angle is formed between with the second light emitting surface and the horizontal reference plane.
