Do you have high blood pressure that you are struggling to control?

 Do you sleep all night, but still wake up tired and unrested?

Has your dentist told you that you grind your teeth and suggested you wear a mouth guard?

An underdeveloped jaw can affect your sleep, airway, heart, brain, and teeth.   In fact, your blood pressure surges 25% during teeth grinding!

What you’ll learn from Dr. Liao:

  • What is a structurally impaired mouth
  • How Impaired Mouth Syndrome covers a wide variety of medical, dental and mood symptoms
  • Why an Impaired Mouth is a slow kill, while Holistic Mouth is a fast heal How to tell a tooth doctor and a mouth doctor

What other people have to say:

“Now I need to adjust my medication with my doctor” — after 15 months of wearing oral appliances to sleep and without diet and lifestyle changes. B.N. reported that her blood pressure was down by 13/10, from 140/87 to 127/77. Moreover, she said, ”My blood pressure does not shoot up right away like it used to when I forget my medication. My blood pressure now stays normal for a couple of days even when I don’t take the meds. “The aches and pains in my shoulders are improving, too. And I’m not as tired as I used to be – which is important when you’re taking care of six kids!”

“My energy level is much improved — no need for a nap in the afternoon, and no tossing around all night with that CPAP machine on. I would never go back to CPAP. Still using the appliance at night just to keep everything in place. If you are considering it, I would suggest looking at it as well.”

“I came to Dr. Liao suffering from back pain for most of my life. I have seen chiropractic doctors and nutritionists but never saw any real relief. Now, after wearing an oral appliance, my airway has opened up 70% and my low back pain is almost nonexistent. After 15 months, he reported that his blood pressure had “gone down quite a bit: from 140/90 to 110/60 now. So it’s been a huge improvement – I feel so much calmer.”

First and foremost, I am experiencing much better sleep, and I am actually dreaming vividly almost every night now! This began happening during the FIRST WEEK of use! I used to have dreams like this when I was a kid, but before using this appliance, not in YEARS! I am sleeping all the way through the night as well. I am so much more awake and alert in the mornings, and all the way throughout the day, for that matter. As for the side effects, I am seeing my skin glowing, my eyes are brighter, and the bags under my eyes are gone! I feel like my circulation all around is much better, and I do not ‘gasp’ for air anymore.

“I’ve had neck pain for ages,” said Dr. P.Y., a chiropractic doctor who came to see me. “And I’ve been grinding my teeth for as long as I can remember. My neck pain gets relief from chiropractic adjustment, but it comes back the next day.” In Dr. P.Y.’s case, her oral appliance also served as a sleep aid, TMJ appliance, and palatal expander. Three weeks after starting therapy, she reported that her pain “goes away within a half hour of putting on my bite correction appliance, and I feel refreshed in the morning after sleeping with my appliance overnight.”
