What a Flat Occlusal Plane Does to Your Body (It's Not Just a Dental Problem)
Share
Most people have never heard the term "occlusal plane." And honestly, that's part of the problem.
Because what happens to your occlusal plane — specifically whether it has a healthy upward arc or whether it's been flattened out — has consequences that extend far beyond your mouth. We're talking about your spine, your brain, your organs, your face, your energy, your mental health. All of it.
I know this sounds extreme. I thought the same thing before I lived it firsthand.
In 2014, a dentist in Vietnam drilled down my back teeth. Within two to three months, I was well on my way to a neurological disease. My body changed dramatically. My mental health fell apart. My flexibility deteriorated. My vision darkened. I went from a guy who had traveled to ninety countries and thrived socially to someone who didn't want to leave his apartment.
What that dentist had done — whether he understood it or not — was flatten my occlusal plane.
That's what started all of this for me. And that's why I need to talk about what a flat occlusal plane actually does to the human body.
First, What Is the Occlusal Plane?
The occlusal plane is the surface along which your upper and lower teeth make contact when you bite down. In a healthy mouth, this plane isn't actually flat — it follows a gentle upward arc toward the back of the mouth. That arc is called the Curve of Spee.
From the side, the contact line between your upper and lower teeth should slope upward as you move toward the back molars. Front teeth sit lower, back teeth sit higher. That curve is structural. It's load-bearing. It's there for a reason.
When that curve flattens out — whether from orthodontic treatment, dental grinding, extractions, or a dentist physically drilling down your back teeth — the structural support your skull depends on starts to disappear.
And when that happens, things go wrong. Not just in your mouth. Everywhere.
The Skull Operates Like a Balloon
Here's the framework you need to understand everything else in this article.
Your skull is covered by soft tissue — fascia, muscles, connective tissue — that functions a bit like a balloon. When the teeth provide the correct vertical height and the occlusal plane has a healthy curve, that soft tissue stays inflated. The skull holds its shape. The brain sits inside it with adequate space. The spine aligns correctly below it.
When the occlusal plane flattens, dental height collapses. And when dental height collapses, the soft tissue begins to deflate — slowly crushing inward around the skull, deranging the cranial bones, and sending a cascade of structural compensation down through the entire body.
This isn't a theory I read in a textbook. I've experienced this process going in both directions multiple times over the past decade — collapsing my structure and then restoring it, at least four or five times. The patterns were consistent every single time.
What Actually Happens When Your Occlusal Plane Flattens
1. The Skull Twists and Compresses
The first thing that changes when the Curve of Spee disappears is the skull itself. The cranial bones begin to derange. The skull doesn't just sink uniformly — it twists.
I have an X-ray from 2015 that shows this clearly. My skull was visibly rotated and asymmetric at the peak of my collapse. After I began restoring my occlusal geometry, it had noticeably unwound. The difference isn't subtle.
This isn't something you'd necessarily see in the mirror right away. But over months and years, facial asymmetries deepen, the face narrows, and the proportions that used to define your features start to deteriorate. Cheekbones flatten. The jaw recedes. The neck shortens.
What most people chalk up to "aging" is very often just structural compression from a flattened bite.
2. The Spine Compensates — and Pays the Price
The skull and spine are one connected system. When the skull twists, the spine twists with it to compensate and keep the eyes level. This is basic physics — the body will do whatever it takes to maintain balance.
But compensation isn't health. A compensating spine is a stressed spine. And a stressed spine means compressed discs, tight muscles, impaired nerve function, and postural problems that no amount of stretching, chiropractic, or yoga is going to permanently correct.
I spent years confirming this with what I called a tracking splint — a flat plane splint and occlusal paper I used to measure contact points over time. Every time something changed in my mouth, the spine changed with it. Every time I exercised without wearing a mouthguard, I would regress. The mouth and the spine moved together like a single unit. Always.
You do not change your spine without changing your occlusion. Period.
3. The Body Widens and Loses Its Shape
This was one of the more startling things I observed after my teeth were drilled flat in 2014. I was a lean guy — had been my whole adult life. I wasn't changing my diet. I was still exercising three to four times a week. And yet my body began to widen.
My neck started to disappear. My shoulders rounded forward. I looked like I had aged a decade in about six months.
Think of the soft tissue covering the entire body as a full-body wetsuit. When it deflates, it pulls inward — and it drags the skeleton with it. Bones shift. Joints compress. The body takes on a collapsed shape that no amount of gym work is going to correct, because the structural driver is happening at the level of the bite.
When I restored my bite geometry, the body reinflated. The width reduced. The posture improved. Without me specifically working on any of it.
4. Cognitive Function Deteriorates
The brain sits inside the skull. If the skull is being compressed, the brain is being compressed.
Research has consistently shown that people with neurological diseases — Alzheimer's, Parkinson's, multiple sclerosis, dystonia — present with reduced brain volume on imaging. The medical establishment attributes this to the diseases themselves. But what if it works the other way? What if the compressed brain is the cause, not the consequence?
When I lost my occlusal height in 2014, my cognitive function changed noticeably. Brain fog I'd never had before. Concentration dropped. Social sharpness — something that had defined me my entire adult life — was gone.
When I restored the structure, the clarity came back. Rapidly. And consistently, every time I went through the cycle.
A friend of mine, Marcello Mazza, had an even more extreme version of this story. He was a fit man in his forties — running marathons — when a TMJ dentist drilled his teeth flat. Within months he was in a wheelchair with cervical dystonia. He spent seven years in that condition. When we figured out the biomechanics together around 2015–16, he restored his Curve of Spee and recovered completely.
That's not a coincidence. That's cause and effect.
5. Sensory Function Takes a Hit
As my bite geometry collapsed in 2014, my vision got worse and noticeably darker. My hearing seemed to dull. These aren't things most people would ever connect to their teeth.
But when the skull compresses, it doesn't do so selectively. Every structure inside it gets affected — including the nerve pathways and sensory processing centers that govern how we see and hear. When I restored my bite, these things improved. Every single time.
6. Organ Function Becomes Impaired
The spine houses the nervous system, which governs virtually every organ in the body. A twisted, compensating spine means impaired nerve signals reaching those organs. Digestive issues, immune dysfunction, sleep disruption — these are all downstream effects of the same structural collapse.
When my occlusal plane was flattened in 2014, I had digestive problems I'd never had before. My sleep quality crashed. These things didn't need separate explanations. They were all part of the same process.
I am now confident that this structural distortion is at the root cause of things like heart attacks, strokes, and certain cancers. Bold claim, I know. But when you've watched the same body collapse and recover repeatedly, and the patterns are consistent every time, you stop calling it a theory.
7. Mental Health Follows the Structure
Within months of having my teeth drilled flat, I went from one of the most extroverted, socially engaged people I knew to someone experiencing social anxiety and panic attacks for the first time in my life. A psychiatrist prescribed antidepressants. I threw them away after two days — not because I thought I was fine, but because something told me this wasn't a neurochemical problem. It was structural.
When I started restoring my bite, the mental health improved in tandem. Not gradually over years of therapy. Rapidly — like a switch had flipped.
The skull houses the brain. The brain governs mood, anxiety, motivation, and social behavior. Compress the skull, compress the brain, and you compress all of those functions with it.
How a Flat Occlusal Plane Gets Created in the First Place
Most people don't realize how common this is — or how many routine dental procedures contribute to it.
Orthodontic treatment is the most frequent culprit. Braces and aligners routinely flatten the Curve of Spee, either by design or as a side effect of moving teeth to an artificial position. The teeth end up looking straighter but lack the natural structural arc the skull depends on.
Dental extractions are another major cause. Remove back teeth and the remaining teeth drift inward. The curve collapses. The structural support diminishes.
Night grinding also wears down occlusal height over time, gradually flattening the curve from the top down.
And in my case — direct drilling. A dentist literally ground my back teeth down to level them. The damage was immediate and severe.
Restoring the Curve Is the Fix
Here's the takeaway: if a flat occlusal plane causes the collapse, then restoring the curve reverses it.
That's the logic behind RevivOne. The mouthguard adds vertical height between the teeth — with an unlocked occlusion that doesn't force the jaw into a fixed position — and allows the skull and body to begin reinflating.
It works because the physics work. The soft tissue stretches. The skull decompresses. The spine begins to unwind. The brain gets more room. The organs get more space.
None of this requires a $30,000 dental procedure. It requires understanding what the occlusal plane actually does to your body — and then addressing it at the root.
Most people walking around with a flat bite have no idea why they feel the way they feel. They're treating back pain, brain fog, anxiety, and digestive issues as separate, unrelated problems. They're not separate. They're one problem with one structural origin.
Fix the curve. Fix the system.
