Quotes:

“The technical term for [myofunctional therapy] is the neuromuscular re-education of the oral and facial muscles. It's essentially like having a personal trainer for the muscles of the oral facial complex. We have common goals that we work on with our patients. Essentially, it's to restore proper oral rest posture, which, you might not know what that is. So, as you're listening to me, I want you to breathe, and I want you to think about where you feel your tongue inside your mouth. Weird question. All my patients, when they come in, they're like, ‘Well, I don't know. Nobody has ever asked me that before. My tongue is moving everywhere now that you brought so much attention to my tongue.’ But if you're having correct tongue posture, if you think about where you say the letter “N”, where the tip of your tongue hits up behind your upper front teeth, essentially, right on your incisive papilla, that is where the tip of your tongue should rest. That whole tongue should actually be resting up in the roof of the mouth. The lips should be closed, and we should be breathing through our nose. This is really what our goal is as a myofunctional therapist, is to restore this posture.” (4:00—5:07)

“Whoever you are listening, whether you're a pediatric dentist, general dentist, orthodontist, cosmetic dentist, sleep dentist, there's a place for myofunctional therapy in literally every single dental treatment plan.” (6:35—6:48)

“One of the things that I like to explain, whether it's other professionals that I'm lecturing to about myofunctional therapy or patients when they come in, it's really important to understand that structure and function go hand in hand. You can't really have one without the other. You can slap braces on somebody. You can get those teeth to move while they're actually physically in the braces. But what about when you take those braces off? What's going to happen if that soft tissue dysfunction was not corrected? We see a lot of patients with orthodontic relapse. So, patients that have tongue thrust — that can even impact cosmetic dentistry. I mean, how good is doing cosmetic dentistry on somebody that's always thrusting their tongue? What good is that cosmetic dentistry if we can't keep those teeth inside our mouth? Periodontal disease, there's a link between that. Think about the forces of clenching and grinding, bruxism, what that does to the periodontium. Mouth-breathing, we already know what that does to the health of our gums. So, there's a place for myofunctional therapy everywhere.” (6:54—7:56)

“I think one of the most important things is we want to understand, truly, the importance of nasal breathing and that it's not okay to breathe through our mouth. Yes, maybe when you're doing some high-intensity workouts, that's fine. Otherwise, those lips should always, always, always be closed during the day and at night. You hear patients come in and they're talking about maybe their children, and they might snore. They might snore a little bit. Or, ‘My husband is snoring. I have to sleep in the other room.’ Snoring is not okay no matter who you are, what age you are. We should be sleeping in our rooms, nice and quiet. I always tell my parents, ‘You want to go in your child's room and put your finger underneath their nose to make sure that they're breathing. That's how quiet we want our children to be when they're sleeping.’” (7:56—8:45)

“You could be the best myofunctional therapist in America, or to ever exist. But if your patient cannot breathe through their nose, it is very hard for us to be successful. So, we have to see, what is that root cause of mouth-breathing? Are there enlarged tonsils, enlarged adenoids, turbinates? Do they have a tongue-tie that's impacting their ability to get their tongue up in the roof of their mouth? There are so many things that we want to look at.” (9:45—10:08)

“There are so many kids out there that are truly suffering and that are getting mislabeled as ADHD, getting mislabeled with behavioral issues. Kids respond differently to not getting enough sleep than we do as adults. As adults, we're lethargic. We want to sit there, and we want to watch Netflix. Kids become hyperactive. They are trying to do everything they can to possibly keep themselves awake. And there's a big correlation — I want to say it's like 75% of patients — children that are diagnosed with ADHD actually have an underlying sleep-disordered breathing issue going on. That's the other thing I feel like in dentistry — there are not enough practices that are focusing on sleep, even though we should, because every dentist should be screening for sleep-disordered breathing. But we think about sleep apnea, and that's really all that anybody thinks about. But sleep apnea is that final destination we don't want to get to. Sleep-disordered breathing is really an umbrella term — mouth-breathing, snoring, upper airway resistance. Then, we get to full-blown sleep apnea. So, again, it's not normal to have any kind of snoring, no matter how old you are.” (11:45—12:57)

“[There are] simple questions that can be asked about sleep, sleep patterns, and behavior. I teach a course to other dental hygienists to become myofunctional therapists. I co-teach with my partner, Karese Laguerre. We came up with a screening that you can do in the op. The acronym is BROOMS . . . It's very quick to do in your intraoral and extraoral exam as a registered dental hygienist. You're not taking all this crazy time aside to do this. So, the “B” in BROOMS stands for bruxism. So, any signs of wear going on, any signs of clenching and grinding going on. Maybe your patient has massive tori in their mouth. Well, those grew from somewhere.” (13:45—14:35)

“The “R” [in BROOMS] stands for respiration. How are they breathing? Are they breathing through their mouth? When you're looking at your patients, even before you call your patient from the waiting room, observe them in their natural habitat. How are they sitting? Are they super slumped over? Is their mouth slumped over, open? When you watch them breathe, are you seeing a lot of chest movement, or are you seeing the movement come from their diaphragm? Because that's really that primary muscle that we want to be breathing from.” (14:37—15:06)

“The first “O” [in BROOMS stands for] open mouth. I think the first one is open mouth posture, technically. So, again, monitoring them. Is it typical that they have those lips apart, or are they together? And very simple, you can obviously see their teeth if their lips are apart. So, when parents are like, ‘Oh, I don't know if their lips are together or open,’ well, do you see their teeth? That's a big tail sign. Patients that have to use ChapStick. They might whip out the ChapStick while they're in your chair. There is a reason why your lips are chronically chapped. Aside from the fact that, yes, ChapSticks smell fabulous, and lipsticks and glosses, and things like that, if your lips are chronically chapped, that's a sure sign that you're probably doing some mouth-breathing and have your mouth slumped open.” (15:08—15:56)

“The “M” [in BROOMS] stands for maxillary transverse width. This is something that should be taken, I think, on every single patient and that can be easily done. Take a cotton roll. A cotton roll measures about 37 millimeters. I don't know if it differs from company to company, but generally it's about 37 millimeters. Stick that cotton roll up between three and 14, or the baby second molars, and see if it fits. If we're talking about an adult and you're squishing that cotton roll up between three and 14, they are deficient. There's probably some crowding going on, or they probably have that high narrow palate. For our children, depending on the age, of course, 37 millimeters might be a little bit too big. But by age five, we want to have a 30-millimeter transverse width. And there are not, unfortunately, a lot of five-year-olds walking out there with 30 millimeters. Think about your pediatric patients. We would love to see so much spacing between those primary teeth that you can take a nickel and slide it up there. We don't see that a lot. A lot of parents think, ‘Oh, their teeth are close together. This is great. They're not going to need braces.’ But we know that that's not true. What's going to happen when those exfoliate, and those adult teeth come in? So, it’s a very simple thing you can do.” (15:58—17:20)

“The “S” [in BROOMS stands for] strained mentalis. So, when you're looking at a patient and you ask them to close their lips, you might see some strain going on in this chin area, in that mentalis, having some activation. Even sometimes without them actually closing their lips, you end up seeing some strain here. That can be a sign of a vertical overgrowth. So, maybe that jaw is really growing down versus forward, like we want. A lot of those patients will have longer faces and gummier smiles. It's a lot more difficult for them to actually get that true lip competence. And how simple is that? That's something that can be done in a jiffy as an RDH. That's a good screener for if this patient needs a myofunctional referral.” (17:22—18:10)

“The second “O” [in BROOMS stands for] orally defensive. That's a big one because we see this a lot in the dental world. So, think about, for my hygienists that are listening, you're trying to scale those lower anteriors, and that lower lip is hooked so far over that you're almost standing up to fulcrum to be able to scale down there. There's a reason. Those patients that have severe gag reflex that you're dreading when you, unfortunately, see their name in the schedule and they're due for a full set of X-rays — there's a reason for that. They're trying to protect their airway. That tongue that constantly follows you around, everywhere your mirror goes, that tongue follows. Difficulty retracting the cheek — any kind of oral defensive sign, there's probably some kind of dysfunction going on there.” (18:22—19:05)

“A lot of us myofunctional therapists also do breathing re-education. The type of breathing re-education that I'm trained in is called Buteyko breathing . . . I'm going to give you guys a challenge. I would like for you to try to suction your tongue up to the roof of your mouth like this. And then, I want you to try to
