Rethinking the Mouth: How Airway‑Focused Dentistry Challenges Traditional Care

Snoring, teeth grinding, jaw pain, reflux, and “tired all the time” can look like separate problems, but they often share a hidden thread: the airway. Dr. Mark A. Cruz discusses how airway-focused dentistry reshapes what we look for in the chair and what we should be asking before we drill, straighten, or rebuild. The big shift is simple but powerful: start with the face and breathing, then work back to the teeth.

We talk about why airway-focused dentistry isn’t a niche specialty, it’s a whole-body lens on oral health. Dr. Cruz explains how the tongue’s real job is to help keep the airway open, and why a “big tongue” diagnosis is frequently a misunderstanding of underdeveloped facial structure and limited oral volume. That frame changes how we interpret common dental issues like bruxism, worn enamel, TMJ dysfunction, headaches, and bite instability, and it pushes us to look for root causes instead of chasing symptoms.

The conversation gets especially real when we move to kids. Many families are told their child has attention problems or ADHD, yet the child may be running on fragmented sleep from mouth breathing, enlarged tonsils, or poor nasal airflow. We discuss practical red flags parents notice first, including bedwetting, fidgeting, behavior swings, and learning struggles, plus why restorative sleep is nonnegotiable during growth and brain development. We also tee up a follow-up conversation on barriers to collaboration in the United States and what other healthcare systems may be doing differently.

If you care about sleep apnea awareness, nasal breathing, pediatric airway health, and dentistry that supports long-term wellness, hit play. Subscribe, share this with a friend who snores or grinds, and leave a review with your biggest takeaway.

Welcome And Why Airway Matters

SPEAKER_01 0:03

Welcome to Airway Focused Dentistry with Dr. Mark A. Cruz, the show where better breathing leads to better living. If your nights sound like a lawnmower chorus or your energy's stuck on low battery, you're in the right place. Hosted by Dr. Mark A. Cruz, we explore how the airway impacts your sleep, your health, and your smile. So you can breathe, sleep, and be well. Take a deep breath, and let's get started.

SPEAKER_02 0:32

Airway focused dentistry does not just expand the conversation, it reshapes how we think about oral health, full body health, and collaboration across specialties. Welcome everyone. I'm Julie Schwenzer with Dr. Mark A. Cruz. Dr. Cruz, it's great to chat with you again.

SPEAKER_00 0:48

Yes, good to see you again, Julie.

SPEAKER_02 0:50

Yeah, we always appreciate your insight, especially on this topic. This is going to be an interesting one. So let's dive

Why Airway Changes Dentistry

SPEAKER_02 0:56

in. How does airwave-focused dentistry challenge traditional dentistry and even other healthcare fields?

SPEAKER_00 1:04

Yeah, you know, I I wish it didn't challenge. And in reality, once you know, the individual, the provider, the the clinician really hears and understands what airway-focused dentistry is, it resonates. And so it's just overcoming that obstacle of exposure, if you will, because it's intuitive. And so I argue that it's not a specialty. Now, sleep dentistry, um, which I'm not a big fan of, is uh, you know, not a specialty, but it's certainly something that tends to be viewed on as a specialty. It's very widget-driven for using devices to stop snoring and maybe address sleep apnea versus CPAP. I'm not a big fan in airway-focused dentistry. You you address that population as a tangent to the central focus, which is really looking at the facial skeleton, of which the teeth are part of. You know, the teeth are connected to the bones that make up the face and the airway. And so, as a clinician, if you have a patient that comes in with dental complaints, a garden variety, dental complaints, wear on the teeth, erosion, temper mandibular joint problems, muscle functions, headaches, um, how the teeth come together, we call it occlusion. Those are all central to understanding what's been largely ignored, which is the function and the structure of the airway, of which the tongue is a big part. So when we're in dental school, you know, we're kind of told that, you know, it's it's you you leave dental school with this understanding that's this big structure that's wet and gets in the way of our work, right? And so uh but not realizing that it's super important, it's number one job is to dilate the airway, which addresses our moment-to-moment most important physiologic function, which is breathing. And so, um, as a dentist, when we start really looking at uh the tongue, that most of the time it's not because the ton is too big, although that's what's claimed, it's that the facial structures are not developed enough. So proportionately the tongue does look large for the oral volume that has developed through growth and development. So the genetic condition macroglossia, which is uh an enlarged tongue, is relatively rare. Um, so most of the time when we see a scallop

Teeth, Tongue, And Facial Growth

SPEAKER_00 3:50

tongue or a very large tongue, it's relative to the oral cavity of the development. So I see a lot of adults that when you actually measure and look at anthropologic standards for where the face and and should have developed, um, it's underdeveloped. And I tell my patients just to kind of explain, it's like, you know, you've got, you have a mid-face of an eight-year-old. So uh an eight-year-old at the uh at a healthy eighth year of life in growth and development, you'd see a certain dimension, if you will, where I see adults in, you know, decades later that that's where they are, like some of my eight-year-olds, right? So uh the tongue will be cramped and will cause a lot of those compensations or threaten the confidences that we've talked about. So as a dentist, we really should be stepping back and looking at the patient globally and asking patients beyond the actual tissue that's in trouble, whether it's a broken tooth or the gums or the temperandibular joints, uh, that we tend to focus on that um uh particular area as a local diagnosis while ignoring the global diagnosis,

Treat Root Causes Beyond Symptoms

SPEAKER_00 5:12

even the regional diagnosis. And we tend oftentimes to over-treat the wrong problem. And you know what the ENTs and and the sea physicians, they do the same thing. It's not anyone's fault. It's just the way we were tr trained, as I said before, an allopathic healthcare system. We, you know, stick to that structure as if it's not connected to other tissues that have function, right? And so um, you know, removing tonsils, it's very clear we know after a hundred years of history that they do serve a purpose and that just removing them by itself doesn't necessarily uh provide long-term favorable outcomes for the kid that had them removed. It just solves an immediate problem. Or removing terminus from the nose, or correcting a deviated septum. You know, uh we ought to really be asking the questions, why is that, and really get to the root cause. And that's what an airway-focused mindset is, is looking at why is the patient clenching and grinding so much? And maybe not so being so quick to accept the orthodox explanation that really is uh uncertain. Same thing with reflux. So for an airway-focused uh dentist, uh, I would say it's a part and parcel of just doing what you do in dentistry, whether it's a full mount rehabilitation, a smile design to get a beautiful beautiful, gorgeous uh smile, it's a gorgeous smile because it fits a gorgeous face. So we deal with the facial skeleton. So for me, I treat and look at the patient facially first and then work backwards versus focusing on the teeth first and working outward. So when we do that, then we have better outcomes that have uh better aesthetics, better longevity, better stability, and that the patients are happier and they feel better because they're breathing better, they're sleeping better, and then have quality of life. So that's kind of in a nutshell how I see it, not as a specialty, just a different way of thinking about the same structures, the same problems that our patients present with. Does that make sense?

SPEAKER_02 7:32

Yes. And you know, I was curious too if you could expand on some other examples of airway-related issues that maybe traditional dentists may overlook just because they're not, you know, they're just not aware.

SPEAKER_00 7:46

Yes.

SPEAKER_02 7:48

Like, can you give me an example of what specifically like when I I know before when we spoke, you were talking about, and it was a really great point about how maybe like children who are developing, maybe they have issues because it comes down to sleep, and you know, there's issues there, and it had to do with um they're not sleeping well because of an airway issue. So I was just wondering what you might have run into where that, you know, somebody walked in and they did see a dentist, and maybe the dentist just didn't catch it because, you know, they saw traditional dentists because they just didn't catch it because they just aren't, you know, they just aren't exposed to that and linking the different uh if we can still say specialties together or yeah, yeah.

Kids, Sleep, And Behavior Clues

SPEAKER_00 8:35

No, I see that daily, uh Julie. I it's it's something where you know moms will come in, they're frustrated with uh, you know, not only the the uh pediatric dentist that they see or the orthodontist, uh, but the pediatrician as well. Uh the mama bears have this intuition and understand something else is going on and doesn't make sense, and they're unsettled about the answers that they're getting that doesn't make sense. And so I see that um uh almost almost daily. We talk about breaking the problem down. For example, uh a parent that may be concerned that the child is getting in trouble or struggling in school and they're being diagnosed with ADD ADHD, and they're talking about putting them on medication. They don't want to do that. And uh they want to see what else is going on. When they start understanding that when you don't sleep well, you have fragmented sleep, because it could be enlarged tonsils or your mouth breathing. Um, you didn't you didn't uh develop that muscle strength early on because you were bottle feeding or eating gerber soft foods? These are all very, very common problems that affect how the phase grows, but also affects the the behavior of the kid, their attention. They're cranky. What adult is not on edge all day long when they have really poor quality of sleep and they're out there in the real world slaying dragons, right? Making decisions when the brain is not completely online. And no matter how much caffeine or energy drink you you take, it's an adrenaline-driven state versus you know being chill and calm and you know, even keel. Um, and it starts with really having that good, deep, restorative sleep, which you cannot have if you can't breathe well, especially through your nose or your mouth breathing, you're snoring, you have sleep fragmentation. So that's kind of the whole cabal, if you will, is understanding those things. And it starts with our kids, but they just don't have the ability necessarily to explain to mom. But a lot of these kids will present with bed wetting, you know, hearing problems, vision problems, um, they have inattention, they have uh they act out, they're fidgety. Uh, those are all autonomic nervous system uh issues related to not having that third of their life functioning well, which is that sleep. And that's super important during growth and development when the brain is developing IQ and uh cognitive function, and it's super frustrating for the family, for the parents, having to deal with a wild kid that's running around. It's not his or her fault. They're just acting out based on what they're feeling from um unrestored sleep. So, you know, we can go on in in in uh in depth in a lot of these areas, but um, we really, I always look at, you know, the kid and I'll say, look, or the patient, I'll say, look, I believe that you're perfectly healthy, but you're really compensated. Unless they have a genetic condition, you know, typhoon diabetic, or they truly have uh uh a genetic condition or a cognitive problem. Okay, different story. But for our average individual, um, they're just not functioning competently at their best. So um, those are questions that I start with, and then I work inward and looking at the dental structures.

Part Two Tease And Resources

SPEAKER_02 12:04

Well, thank you, Dr. Cruz. I wish we had more time to discuss this topic. So I invite you to maybe we could go to a part two for this one.

SPEAKER_00 12:14

Sure. Yeah, I'm more than happy to. Thank you, Julie.

SPEAKER_02 12:17

Thank you so much, Dr. Cruz. Yeah, we can talk about maybe some of the barriers of why it might be harder here. Like you mentioned between recordings at in other areas of the world, it it is maybe just uh easier to collaborate with other providers just because of the way the system is set up. And I definitely want to talk to you about that. That works for you.

SPEAKER_00 12:39

Let's drill down on that. Let's talk about um uh you know how other parts of the world are thinking about it and and um what the barriers are for the provider here in the United States, why, why this is not um garden variety knowledge that we should be uh benefiting our population with. So I'll look forward to that podcast. Thank you, Julie.

SPEAKER_02 13:03

Thank you so much, Dr. Cruz. Always shedding light on how airway-focused dentistry is really reshaping the landscape of so many areas of health. So we appreciate your expertise.

SPEAKER_00 13:14

Yeah, thank you. Thank you.
