Oral Appliance Therapy for Sleep Apnea
A custom dental mouthguard can meaningfully treat mild-to-moderate sleep apnea — and it fits in a pocket instead of a bedroom. How mandibular advancement devices work and who they work for.
Key takeaways
- Oral appliances hold the lower jaw forward, enlarging the airway and reducing collapse during sleep.
- Best suited for mild-to-moderate OSA, positional apnea, and patients who refuse or fail CPAP.
- Custom-fitted appliances from a qualified dentist outperform over-the-counter versions significantly in comfort and effect.
- They reduce AHI by roughly 50% on average — less than CPAP, but with much higher patient satisfaction and long-term use.
- Side effects include temporary jaw discomfort and bite changes; regular dental follow-up prevents lasting problems.
