Obstructive sleep apnea (OSA) affects roughly 30 million American adults and remains underdiagnosed — approximately 80% of moderate-to-severe cases go untreated. At Glisten Dental Glendale we provide oral appliance therapy for patients in Glendale who have been diagnosed with OSA but cannot tolerate CPAP, or who have mild-to-moderate OSA where an oral appliance is an appropriate first-line treatment per current sleep medicine guidelines.

What sleep apnea is and why it matters

During sleep, the muscles that keep your airway open relax. In OSA, that relaxation allows the tongue and soft tissues at the back of the throat to partially or fully block the airway. Breathing stops for 10-30 seconds (sometimes longer), blood oxygen levels drop, and your brain briefly wakes you up just enough to restart breathing. This can happen dozens to hundreds of times per night without you remembering any of it.

The consequences are not subtle. Untreated moderate-to-severe OSA is associated with: 2-3x higher risk of cardiovascular events (heart attack, stroke, atrial fibrillation), worsened diabetes control, 6x higher motor vehicle accident rate, significant cognitive decline over years, chronic daytime fatigue, mood disturbances, and reduced life expectancy of roughly 8-12 years in severe untreated cases.

The good news: effective treatment reverses most of these risks to near-baseline within months to years of consistent use.

CPAP first — it’s the gold standard

Continuous positive airway pressure (CPAP) is the first-line treatment for moderate-to-severe OSA per every major sleep medicine guideline. We want to be unambiguous about this. CPAP, when tolerated, has the strongest evidence base, produces the most complete reduction in apnea events, and reverses cardiovascular risk most effectively.

Oral appliance therapy at Glisten Dental Glendale is for patients who have already tried CPAP and cannot tolerate it, or for patients with mild-to-moderate OSA (AHI 5-30) where current guidelines recognize oral appliances as an appropriate alternative first-line therapy.

We are not a CPAP clinic. We do not perform sleep studies. You need a diagnosis from a sleep physician before we make an oral appliance — typically following a take-home sleep study (HSAT) or an in-lab polysomnogram.

How oral appliances work

A mandibular advancement device (MAD) is a custom-made oral appliance worn during sleep that positions the lower jaw slightly forward. This pulls the tongue and soft tissues of the throat forward with it, keeping the airway open. The device is made from dental impressions of your teeth and adjusted over several visits to find the position that opens your airway adequately without causing jaw discomfort.

Titration is iterative. At the first fitting the device advances the jaw minimally; at follow-ups over 2-3 months we progressively advance until either symptoms resolve or you reach a position where further advancement would cause jaw pain. A follow-up sleep study with the device in place confirms the apnea events are adequately reduced.

Who is a good candidate for oral appliance therapy

  • Diagnosed OSA that is mild-to-moderate (AHI 5-30)
  • CPAP-intolerant patients with any severity — commonly those who cannot sleep with the mask, have claustrophobia, travel frequently, or develop chronic skin/sinus issues from mask use
  • Simple snoring without significant apnea where a sleep physician has confirmed oral appliance is appropriate
  • Adequate dental health — enough natural teeth to anchor the device (full dentures disqualify you)
  • Absence of severe TMD — oral appliances can worsen pre-existing jaw joint problems
  • Commitment to nightly use — occasional use doesn’t work

We evaluate your dental and joint health before fabricating the device and decline patients where the risk-benefit doesn’t favor oral appliance therapy. For severe OSA (AHI over 30) with documented CPAP intolerance, we work collaboratively with your sleep physician to evaluate whether an oral appliance is reasonable or whether other alternatives (surgical consultation, hypoglossal nerve stimulator, combination therapy) should be considered.

What treatment looks like at Glisten Dental Glendale

  1. Prerequisite: sleep study and OSA diagnosis from a sleep physician. We will not make an oral appliance without a current diagnosis.
  2. Dental evaluation. Comprehensive exam, panoramic X-ray, TMJ assessment. We confirm you’re a candidate.
  3. Impressions and bite registration. Digital scans of upper and lower teeth plus a bite registration that captures your jaw in a slightly forward position.
  4. Lab fabrication. 2-3 weeks. We use FDA-cleared appliances from established dental labs — typically a SomnoDent, Herbst, or Narval-style device depending on your specific anatomy.
  5. Delivery and initial fitting. We adjust the device to your teeth, demonstrate insertion and removal, review the titration schedule.
  6. Titration visits. 2-4 follow-ups at 2-4 week intervals to progressively advance the jaw position until symptoms resolve.
  7. Efficacy sleep study. Coordinated with your sleep physician — a follow-up HSAT or PSG with the appliance in place confirms the OSA is adequately controlled. This is critical. Symptom improvement alone is not sufficient evidence of effectiveness.
  8. Annual follow-ups. Appliance wear-and-tear checks, device adjustments if your teeth shift, periodic efficacy re-assessments.

Side effects and realistic expectations

Common short-term side effects: increased salivation initially, morning jaw soreness for the first 2-4 weeks, minor tooth discomfort. These typically resolve with continued use.

Longer-term effects we watch for: bite changes (your front teeth may not fully close together in the morning — usually reversible within an hour, occasionally permanent over years), increased TMD symptoms (treatable with appliance adjustment or therapy), tooth movement (rare with properly designed appliances, occasionally seen with long-term use).

Oral appliances do not work for everyone. Roughly 60-70% of appropriate candidates achieve adequate control of OSA with oral appliance therapy; the remaining 30-40% need to return to CPAP, combination therapy, or consider surgical options. We follow you through the process and adjust course if the appliance isn’t working.

Cost and insurance

Custom oral appliance at Glisten Dental Glendale: $1,800-$3,500. Medicare and many medical insurance plans cover oral appliance therapy for diagnosed OSA when CPAP is documented as intolerated. Dental insurance generally does not cover sleep appliances (they’re considered medical, not dental). We bill medical insurance directly when applicable and verify coverage before fabrication.

Self-pay patients: total cost including evaluation, appliance, titration visits, and follow-up is typically $2,500-$4,000.

Frequently asked questions

Can I get an oral appliance without a sleep study?
No. Glisten Dental Glendale requires a current OSA diagnosis from a sleep physician before fabricating a custom oral appliance. Treating sleep-disordered breathing without a diagnosis risks both under-treatment (inadequate appliance for severe cases) and unnecessary treatment (making an appliance for someone who doesn't actually have OSA). Take-home sleep studies are now widely available and accessible, typically covered by medical insurance, and non-invasive. Get the study first, then we build the appliance.
Is an oral appliance as effective as CPAP?
Not quite, but close for the right patients. CPAP reduces apnea events more completely and has the strongest evidence base — it remains the first-line treatment per major guidelines. Oral appliances achieve adequate control in roughly 60-70% of appropriate candidates (mild-to-moderate OSA or CPAP-intolerant patients). The gap in efficacy is often offset by dramatically better adherence — many patients wear an oral appliance every night when they wouldn't tolerate CPAP. An effective treatment used consistently often beats a slightly more effective treatment used sporadically.
How long does an oral appliance last?
5-7 years on average with good care. Factors affecting lifespan: how much you clench or grind against it, care and cleaning routine, whether your bite changes over time (requiring new impressions), and material quality. High-end FDA-cleared appliances (SomnoDent, Herbst, Narval) last longer than lower-cost alternatives. Annual follow-ups at Glisten Dental Glendale catch wear before it affects efficacy — we replace the device when degradation compromises function.
How much does an oral appliance cost in Glendale?
Custom oral appliance at Glisten Dental Glendale: $1,800-$3,500 depending on device type. Total cost including dental evaluation, titration visits over 2-3 months, and first-year follow-ups: $2,500-$4,000 self-pay. Medicare and many medical insurance plans cover oral appliance therapy for diagnosed OSA when CPAP intolerance is documented. Dental insurance generally does not cover — oral appliances are medical, not dental. We verify medical coverage and bill directly when applicable.
Will I have jaw pain from wearing an oral appliance?
Some initial morning soreness is common for the first 2-4 weeks, typically resolving with continued use. Persistent jaw pain is less common but does occur — usually signals the advancement is too aggressive and the device needs adjustment backward. We screen for pre-existing TMD before fabrication and decline the appliance for patients with severe TMJ dysfunction because the device may worsen the underlying problem. If you develop persistent jaw pain after the first month, we reassess.
Can I still snore with an oral appliance?
Most patients snore substantially less or stop entirely. Snoring occurs when air turbulence passes through a partially obstructed airway — opening the airway reduces both the obstruction and the sound. Residual snoring occasionally persists in patients with multi-level airway obstruction (where the tongue isn't the only issue). A follow-up sleep study confirms whether the underlying apnea is controlled — symptom resolution alone isn't enough evidence of effectiveness.
Will my teeth shift from wearing the appliance nightly?
Minor bite changes are common — most patients notice that their front teeth don't quite close together in the morning right after removing the appliance, resolving within an hour of normal activity. Permanent tooth movement over years of use is possible but uncommon with properly designed appliances and regular monitoring. Annual follow-ups at Glisten Dental Glendale catch significant shifts early and we adjust the appliance or make a new one when needed. Report any new bite changes at your follow-ups rather than waiting.
Do I still need the appliance every night?
Yes — every night you sleep. Apnea events occur every night; skipping the appliance means skipping treatment. Travel, overnight stays, naps over 30 minutes — all need the device. Occasional use doesn't produce the cardiovascular and cognitive benefits that consistent use does. If you cannot commit to nightly use, an oral appliance probably isn't the right treatment for you — and we'd rather have that conversation before fabrication than after.
