Our Mission

Specialty care, elevated above the ordinary.

We believe exceptional care for sleep apnea and TMJ is an investment in your long-term health and quality of life. Every patient deserves a thorough evaluation, time to ask questions, and a treatment plan built around what they need — not what an insurance code allows.

That's the practice we built. Unhurried, individualized, and focused entirely on you.

What We Treat

Two conditions. One narrow focus.

Most dental practices treat sleep apnea and TMJ as a side service. We've restricted our entire practice to these two areas — which means deeper training, broader appliance options, and treatment plans that actually address the root cause.

Sleep Apnea & Snoring

For patients diagnosed with obstructive sleep apnea — or those who suspect they have a sleep breathing issue but couldn't tolerate CPAP. We facilitate the entire process: from sleep study, to custom appliance, to follow-up titration.

  • Custom oral appliance therapy (multiple device options)
  • At-home and in-lab sleep study coordination
  • CPAP intolerance solutions
  • Insurance pre-authorization & titration verification

TMJ & Jaw Pain

Jaw pain, popping, limited opening, painful chewing, morning headaches — TMJ disorders are complex and rarely solved with a generic night guard. We perform a full diagnostic exam and design an orthotic appliance specific to your condition.

  • Comprehensive TMJ examination & diagnosis
  • Custom orthotic appliances to deactivate clenching
  • Treatment for joint dysfunction & muscle disorders
  • Coordinated care with your medical team

Why Patients & Providers Choose Us

Specialty care, delivered the way it should be.

We built this practice the way medicine used to be — and the way it should be again. Time, attention, and a treatment plan that fits the patient.

— 01

Multiple appliance options

There is no one-size-fits-all device for sleep apnea or TMJ. We're trained on a wide range of appliances and select the right one for your anatomy, condition, and lifestyle — not whichever device a single rep is selling.

— 02

Every option, fully presented

Dr. Humphreys walks you through every appropriate treatment — what each one involves, the trade-offs, and the expected outcomes — and helps you weigh them. The plan we move forward with is the one you choose. Your treatment, your decision.

— 03

Coordinated, collaborative care

We work alongside your general dentist, primary care physician, sleep physician, or ENT — and communicate clearly throughout. Your existing care team stays in the loop.

5+ Years Experience Insurance & Billing Referral Liaison
Transparent Billing

Why we're out-of-network — and what that means for you.

We get this question often, so we'll answer it plainly. Being out-of-network isn't about charging more; it's about being able to give every patient the time, attention, and treatment they actually need. Here's exactly how it works.

— Sleep Apnea Coverage

Out-of-Network. Fully filed for you.

For sleep apnea, we file claims with all major medical insurance plans and Medicare. We are out-of-network — which means we set our fees based on what good care actually requires, not what insurance arbitrarily decides to pay.

  • Pre-authorization handled by our team
  • Claims filed directly to your insurance
  • Most patients see partial-to-substantial reimbursement
  • Prompt-payment discount available for cash pay or high-deductible plans
— Medicare Patients

Non-Participating Medicare Provider.

We are a Non-Par Medicare provider. This means we still treat Medicare patients and still file your claim — but Medicare reimburses you directly rather than the practice. This preserves our ability to deliver thorough, individualized care without Medicare dictating treatment limits.

  • Yes, we accept Medicare patients
  • We file your Medicare claim for you
  • Medicare pays you directly (limiting-charge rules apply)
  • Full documentation provided for any supplemental coverage
— TMJ Therapy

Self-pay. Documentation provided for reimbursement.

For TMJ therapy, we don't file insurance claims directly — most plans process TMJ as an out-of-network medical benefit, and reimbursement varies widely. We provide all the documentation, diagnosis codes, and treatment codes you need to submit a claim or call your member services for an estimate before treatment.

  • Diagnosis & treatment codes provided up front
  • Itemized statements for insurance submission
  • HSA/FSA eligible
  • Financing options available
— What This Means For You

The trade-off, stated honestly.

You may pay more out of pocket up front than you would at a high-volume in-network office. In return: longer appointments, multiple appliance options, a doctor who knows your case, and a treatment plan designed for your outcome — not your insurance company's bottom line.

  • No 15-minute appointments
  • No "covered" appliance you can't tolerate
  • No surprise referrals between disconnected offices
  • A direct relationship with your provider
A Note on Why This Matters Insurance reimbursement for dental sleep medicine and TMJ therapy is structured around volume, not outcomes. Practices that accept all in-network rates are forced to compress visits, limit appliance choices, and prioritize codes that pay. We believe these conditions deserve more — so we built a practice that can give it.
