Oral appliance therapy Downtown Los Angeles. Dr. Kevin Chin at City of Angels Dentistry provides custom oral appliances for patients with sleep apnea, bruxism, and related sleep and bite disorders.


Oral appliance therapy is one of those areas where dentistry and sleep medicine overlap, and patients sometimes don't realize their dentist can help. Dr. Kevin Chin has been providing custom oral appliances in Downtown Los Angeles since 2018 — for sleep apnea patients who need a CPAP alternative and for bruxism patients who need effective teeth protection at night. The consultation clarifies which appliance is appropriate for your specific situation and what the process looks like.
Dr. Chin determines which appliance is appropriate — a mandibular advancement device for sleep apnea or a night guard for bruxism. Sleep apnea cases require a physician diagnosis first.
Impressions are taken and your custom appliance is fabricated in a dental lab for precise fit.
The appliance is fitted and adjusted as needed. Dr. Chin monitors effectiveness and bite changes at regular follow-up appointments.
Oral appliance therapy at City of Angels Dentistry includes custom mandibular advancement devices for sleep apnea and precision-fitted night guards for bruxism — both addressing conditions that damage teeth and affect sleep quality. Same-week consultations available in Downtown LA.

Oral appliance therapy refers to the use of custom dental devices to manage sleep-related conditions including obstructive sleep apnea and bruxism. At City of Angels Dentistry in Downtown LA, Dr. Kevin Chin provides mandibular advancement devices for sleep apnea patients and custom night guards for patients who grind or clench their teeth during sleep.
The two primary conditions treated with oral appliances at City of Angels Dentistry are obstructive sleep apnea — where a mandibular advancement device keeps the airway open during sleep — and bruxism — where a custom night guard protects teeth from grinding forces. Both require custom fabrication for effective treatment.
For sleep apnea appliances, a physician diagnosis is required before treatment begins. For night guards, no referral is needed — Dr. Chin can assess, fabricate, and fit the appliance at City of Angels Dentistry. If you're unsure which appliance is appropriate, calling the office for a consultation is the best first step.
After impressions are taken, custom appliances are typically ready within 2–3 weeks. Dr. Chin fits the appliance and makes any necessary adjustments at a follow-up appointment.
City of Angels Dentistry is at 1127 Wilshire Blvd, Suite 1100 in Downtown LA — accessible from the Financial District, Bunker Hill, the Arts District, Koreatown, Echo Park, and Silver Lake.
Some mandibular advancement devices also provide bruxism protection. However, the optimal design for sleep apnea and the optimal design for bruxism differ. Dr. Chin advises on which appliance or combination of appliances is most appropriate for your specific situation.
Cost depends on the type of appliance. Night guards may be covered by dental insurance. Sleep apnea appliances may be covered by medical insurance. The office assists with benefit verification for both.
A mandibular advancement device repositions the lower jaw forward to keep the airway open during sleep — it treats sleep apnea. A night guard places a hard barrier between upper and lower teeth to absorb grinding forces — it protects teeth from bruxism. They serve different purposes and are not interchangeable.
Night guards may be covered by dental insurance when bruxism is diagnosed. Sleep apnea oral appliances may be covered by medical insurance when sleep apnea is diagnosed and CPAP intolerance is documented. The office verifies coverage for both types.
