Oral phototherapy applicators are disclosed that are sized and shaped so
as to fit at least partially in a user's mouth and have at least one
radiation emitter coupled to an apparatus body to irradiate a portion of
the oral cavity with phototherapeutic radiation in at least two separate
spectral bands. In one embodiment, the spectral bands are distinct. In
another, the bands overlap but provide different therapeutic effects. The
apparatus can further include bristles to provide a phototherapeutic
toothbrush. Alternatively, the apparatus body can be adapted for
placement in a fixed position relative to the oral cavity during
phototherapy.
