If you've been told you have an overbite, your first thought probably went straight to braces or Invisalign. Those are valid options, but they only address how your teeth sit, not why they ended up that way. For many people, the root cause of an overbite isn't dental at all. It's muscular. That's where myofunctional therapy for overbite correction comes in.
At Myofunctional Therapy of Kansas, we work with children and adults throughout the Wichita area who are looking for a more complete, whole-body approach to bite and jaw health. This post walks through what an overbite actually is, how muscle dysfunction contributes to it, and how orofacial myofunctional therapy fits into treatment.
What Is an Overbite, Really?
An overbite means your upper front teeth extend too far over your lower front teeth when your mouth is closed. A small vertical overlap is completely normal, but when that overlap is significant, it can affect chewing, speech, jaw comfort, and even breathing.
Overbites are usually categorized as either skeletal (related to jaw bone structure) or dental (related to how the teeth are positioned). Dental overbites, the more common type, are frequently connected to habits and muscle patterns that developed over time, often starting in childhood.
The Muscle Connection Most People Miss
Your tongue, lips, and facial muscles do far more than help you eat and talk. They exert constant, low-grade pressure on your teeth and jaw, 24 hours a day. When those muscles function well, they support proper jaw development and tooth alignment. When they don't, the cumulative pressure can push teeth into misaligned positions.
Low tongue posture is one of the most common culprits. When the tongue rests on the floor of the mouth instead of gently pressing against the palate (the roof of the mouth), it removes a key structural force. Without that upward pressure, the upper arch can narrow, the lower jaw may shift back, and an overbite can develop or worsen.
Mouth breathing, tongue thrust during swallowing, thumb or finger habits, and prolonged pacifier use can all reinforce these dysfunctional patterns. Orofacial myofunctional therapy targets exactly these habits and postures.
How Myofunctional Therapy Addresses Overbites
Orofacial myofunctional therapy is a neuromuscular retraining program. Think of it as physical therapy for the muscles of the face, mouth, and throat. Through a structured sequence of myofunctional therapy exercises, you retrain the tongue, lips, and jaw to function the way they were designed to.
For overbite correction specifically, the work typically focuses on:
- Tongue posture: Teaching the tongue to rest on the palate consistently, which provides gentle upward and forward pressure on the upper jaw
- Lip seal: Restoring the natural resting seal between the upper and lower lips to reduce forward pressure on the upper teeth
- Swallowing pattern: Correcting tongue thrust, where the tongue pushes forward or down during swallowing instead of rising to the palate
- Nasal breathing: Transitioning from habitual mouth breathing to nasal breathing, which supports proper tongue posture and jaw development
These are not quick fixes. They are habit changes that take consistency over weeks and months. But they address the forces that caused the overbite in the first place, which is something orthodontics alone rarely does.
Is Myofunctional Therapy a Replacement for Braces?
This is the question we hear most. The honest answer: it depends on the severity and cause of the overbite.
For mild to moderate dental overbites where muscle dysfunction is a significant driver, myofunctional therapy can produce meaningful improvement on its own. For more significant structural cases, it works best as part of a coordinated plan alongside an orthodontist or dentist. In those situations, therapy addresses the underlying muscle patterns before, during, or after orthodontic treatment, which dramatically reduces the chance of relapse.
Orthodontic treatment moves teeth. Myofunctional therapy changes the forces that act on those teeth every day. Both matter. Without addressing the muscular component, teeth are far more likely to drift back toward their original position after braces come off.
Many of our Wichita patients are referred by orthodontists and dentists who recognize that correcting the bite without correcting the muscle pattern is an incomplete solution. If your provider hasn't mentioned myofunctional therapy, it may be worth asking about it.
Who Is a Good Candidate?
Myofunctional therapy for overbite correction is appropriate across a wide age range. Children tend to respond fastest because their jaws are still developing, but adults see real results too. It's particularly worth exploring if you or your child have:
- Been diagnosed with a dental overbite
- A history of mouth breathing, open-mouth rest posture, or chronic snoring
- A tongue tie (ankyloglossia), which often contributes to low tongue posture
- Experienced orthodontic relapse after braces
- Jaw tension, TMJ discomfort, or difficulty chewing
A thorough assessment is the only way to know whether your overbite has a significant myofunctional component. During an initial evaluation, we look at tongue posture and strength, swallowing pattern, breathing habits, and lip function to understand what's driving the bite pattern.
What to Expect from Treatment
A typical myofunctional therapy program runs 6 to 12 months, with exercises practiced daily at home between sessions. Early sessions focus on building awareness of current habits, which most people have never consciously noticed. Subsequent sessions build new patterns progressively, with each exercise building on the last.
Progress is gradual but cumulative. Most patients start noticing changes in jaw comfort, breathing, and tongue posture within the first few months, with bite improvements visible over a longer horizon, especially when working in coordination with an orthodontist.

If you're looking for a non-braces approach to overbite treatment, or if you want to make sure your child's orthodontic results last, myofunctional therapy is worth a serious look. Our overbite treatment page has more detail on how we approach this at Myofunctional Therapy of Kansas.
You can also reach out directly to schedule an evaluation. We work with patients throughout Wichita and the surrounding Kansas communities, and we'd be glad to help you understand whether myofunctional therapy is the right fit for your situation.
