Sleep apnea mouth guards (oral appliances or mandibular advancement devices) are dental devices that hold the lower jaw forward during sleep, keeping the airway open. Sleep apnea mouth guard is an effective alternative to CPAP for many patients, particularly with mild-moderate OSA.
How they work
Mandibular advancement devices (MADs):
- Move lower jaw forward 4-8 mm typically
- Pulls tongue and soft palate forward
- Keeps airway open during sleep
- Adjustable in most modern devices
Custom vs OTC
Custom (sleep dentist):
- Made from impressions of your teeth
- Adjustable
- Best fit and comfort
- Cost: $1500-3500
- Insurance often covers
OTC (“boil and bite”):
- Cheap (under $200)
- Generic fit
- Not effective for moderate-severe OSA
- Quality varies widely
- Generally not recommended for actual OSA treatment
Effectiveness
- Effective for mild-moderate OSA
- Less effective than CPAP for severe OSA
- Better adherence than CPAP for many
- Should be titrated and verified with follow-up sleep study
The process
- Sleep study confirms OSA diagnosis and severity
- Sleep dentist evaluation (separate from regular dentist)
- Impressions or scans
- Device fabrication (2-4 weeks)
- Fitting and titration
- Follow-up sleep study to verify effectiveness
Side effects
- Jaw soreness initially
- Tooth movement over time
- TMJ symptoms
- Bite changes
- Excessive salivation initially
Most side effects manageable; serious problems uncommon with proper fit.
