CPAP-MAD combo: (CPAP) is considered to be the treatment of choice for sleep apnea. Mad (mandibular advanced devise) is oral appliance and a viable alternative with growing use, particularly in patients with mild/moderate sleep apnea. Combination CPAP and mad could be the answer in your case. Rec. See an orofacial pain doctor specializing in dental sleep medicine.
