An open bite is a visible gap between your upper and lower front teeth when you bite down. Your back teeth touch but your front teeth don't meet. It affects how you eat, how you speak, and how you feel about your smile.
Open bites are less common than crowding or overbites, but they're very treatable, especially when we catch them early. Dr. Tahir and Dr. Lia treat the cause and the bite together so the problem doesn't come back. Your first visit is free.

When you close your mouth, your front teeth should overlap slightly. With an open bite, they don't. There's a visible gap between the upper and lower front teeth even when your jaw is fully closed. You can't bite through a sandwich. You can't tear lettuce with your front teeth. The gap is always there.
Most open bites happen in the front (anterior open bite), but they can show up on the sides or back of the mouth too.
The most common cause, especially in kids. The thumb sits between the upper and lower teeth and holds them apart. Do that long enough and the teeth grow around the habit. The bite stays open even after the thumb stops.
Every time you swallow, your tongue pushes forward. If it pushes against or between your front teeth, that repeated force keeps the bite from closing. Tongue thrust can create an open bite and it can prevent one from being fixed if it's not addressed.
Some people are born with a jaw that grows at a steep angle (orthodontists call it a high-angle pattern). This naturally pulls the front teeth apart and makes an open bite more likely. It's genetic and it's not caused by a habit.
Breathing through the mouth instead of the nose changes how the jaw develops and how teeth come in. Over time, it can contribute to an open bite, especially in kids whose jaws are still growing.
Swollen tonsils or adenoids can block the airway, which forces mouth breathing. That mouth breathing affects jaw development. It's a chain reaction that often ends with an open bite.
An open bite isn't something you grow out of. Without treatment, these problems either stay the same or get worse:
The bottom line: an open bite affects more systems than most people realize. Eating, speaking, breathing, jaw health, tooth longevity. So fixing it is about real function as much as your smile.
Before we touch the bite, we figure out what created it. If thumb-sucking is the driver, we help break the habit. If tongue thrust is the issue, we address it directly. If mouth breathing is a factor, we may recommend an ENT evaluation to check for airway obstruction.
This step matters more with open bites than almost any other case. Fix the bite without fixing the cause and the open bite comes right back. Dr. Tahir and Dr. Lia have seen that happen with patients who were treated elsewhere. We don't repeat that mistake.
For patients with tongue thrust or skeletal open bite patterns, a bite plane is one of our most effective tools. It's a fixed appliance that sits behind your lower teeth and does two things:
Bite planes work especially well in growing kids because we're not fighting biology. We're removing the obstacle and letting growth do the rest. Most patients wear a bite plane for 6 to 12 months, usually followed by braces for final alignment.

After the cause is addressed and any appliance phase is complete, braces finish the job:
The braces phase typically runs 18 to 24 months after any initial appliance work. Braces give us the control to make precise vertical movements that aligners can't reliably do, which is why we lead with braces for open bite cases.
If your child is still thumb-sucking or tongue-thrusting, we work with you and your child to break the habit. Sometimes starting treatment is the motivation kids need to stop. Having braces or an appliance in the mouth makes the habit physically harder to continue, and most kids adapt quickly once they understand why it matters.
Open bites respond to early treatment better than almost any other bite issue. Here's why:
Between ages 6 and 10, your child's jaw is still growing and their teeth are still coming in. If we catch the open bite during that window, we can stop the habit that's causing it, place a bite plane to let the teeth close naturally, and guide the jaw into a better growth pattern.
What could take 24 to 36 months to fix in a teenager can often be managed in 6 to 12 months in a younger child. The jaw is more flexible. The teeth are more responsive. The habit is easier to break.
Miss that window and the bite continues to develop around the problem. The open bite gets deeper. The skeletal pattern sets. Treatment gets more complex. In severe adult cases, surgery may be the only option.
That's why we recommend every kid comes in at age 7. Not to start treatment. To catch things like this while the fix is still simple.
Open bites are one of those issues that look small but affect a lot. Eating, speaking, breathing, jaw health, confidence. If you or your child has a gap between the front teeth when biting down, don't wait to see if it resolves on its own. It usually doesn't.
Dr. Tahir and Dr. Lia have been treating open bites for over 30 years. Bring your questions. Bring your concerns. Bring the kid who's still sucking their thumb and you're not sure what to do about it.
Your first visit is free, and you'll leave knowing what's causing the open bite and how we'll treat it.











Depends on severity. A small gap might be purely cosmetic. A larger one affects chewing, speech, and tooth wear over time. If it's caused by tongue thrust or mouth breathing, fixing it early prevents bigger problems down the road. Come in and let Dr. Tahir and Dr. Lia take a look. They'll tell you exactly what you're dealing with and what it needs.
It usually gets worse as permanent teeth come in. Thumb-sucking keeps teeth apart, speech can be affected, and treatment gets harder the longer you wait. Early treatment prevents all of that. Better to check now than wish you had later.
Depends on severity. With a bite plane first: 6 to 12 months on the appliance, then 18 to 24 months with braces. Braces alone: 18 to 24 months. Mild cases can wrap up faster. The real timeline depends on what's driving your open bite and how your teeth respond to treatment. Dr. Tahir and Dr. Lia will give you your specific timeline at a free visit.
Yes. Bite planes work best in growing kids, but braces work well for adults too. Most adult open bites respond well to orthodontic treatment alone. Severe skeletal cases may benefit from surgery, but we'd only bring that up if it actually applies to your case.
Not if we address it properly. That means correcting the bite, breaking the underlying habit if there is one (tongue thrust, thumb-sucking), and wearing your retainer consistently. Skip any of those and relapse is more likely. We'll set you up with a retention plan that keeps your bite stable long-term. And if a referral to another specialist helps with stability, we'll make that happen too.
