Use this guide to correcting open bite to understand causes, braces and clear aligners, treatment timing, and what to expect at an orthodontic visit today.
An open bite can make a simple bite feel surprisingly complicated. You may notice that your front teeth do not touch when your back teeth come together, that biting into a sandwich is awkward, or that a child’s speech and chewing habits seem affected. This guide to correcting open bite explains what may be causing the gap, which treatments can help, and why an orthodontic exam is the best place to start.
An open bite is not just a cosmetic concern. For some patients, it affects how the teeth function, how the jaw feels, and how confidently they smile. The good news is that orthodontic treatment can often improve an open bite at many ages. The right approach depends on the cause, the patient’s growth stage, and the movement needed to create a healthy, stable bite.
An open bite means certain upper and lower teeth do not meet when the mouth is closed. The most common type is an anterior open bite, where the front teeth remain apart even while the back teeth touch. A posterior open bite is less common and occurs when the back teeth do not meet properly.
A small space may be easy to overlook, especially in a child with baby teeth. But if it continues as permanent teeth come in, it is worth an orthodontist’s attention. Waiting is not always harmful, but guessing at the cause can delay the care that would be most effective.
Open bites can develop for different reasons, and more than one factor can be involved. In younger children, thumb sucking, prolonged pacifier use, tongue thrusting, or mouth breathing may influence how the teeth and jaws grow. These habits are not a reason for blame. They are simply useful clues when planning treatment.
In teens and adults, an open bite may be related to tooth position, jaw growth, bite patterns, or a relapse after past orthodontic treatment. Some people naturally have a more vertical facial growth pattern that makes the bite more likely to open. Others may have teeth that have shifted because retainers were not worn as directed after braces.
This is why online photos and one-size-fits-all advice only go so far. Two patients can appear to have the same gap between their front teeth but need very different treatment plans.
Correcting an open bite is not always about simply pushing the front teeth together. If the underlying habit, jaw relationship, or tongue posture is not addressed, teeth may move back toward their old positions after treatment.
At an orthodontic consultation, the orthodontist will look at your teeth, bite, jaw relationship, facial growth, and dental history. Digital scans or X-rays may be recommended when they will help clarify what is happening beneath the surface. For children, the visit also considers what teeth are still developing and whether early treatment could guide growth in a helpful direction.
You should leave this conversation with a clear explanation of the recommended path, whether treatment should begin now or be monitored, and what the expected timeline and costs may look like. There should be no pressure to decide before you understand your options.
Traditional braces are a highly effective option for many open bites. Because brackets and wires give the orthodontist close control over individual tooth movement, braces can be especially useful for more complex cases, significant rotations, or bites that need careful vertical correction.
Metal braces are durable and efficient. Clear braces may be an option for adults and older teens who prefer a less noticeable look. The best choice is not about which treatment is “better” in general. It is about which one gives your orthodontist the control your bite needs.
Clear aligners, including Invisalign, can treat many mild to moderate open bites and some more involved cases. They are removable, discreet, and convenient for eating and brushing. For adults who want a lower-profile option, that can be a major advantage.
The trade-off is consistency. Aligners need to be worn for the number of hours your orthodontist recommends, typically most of the day and night. Taking them out often or forgetting to switch trays on schedule can slow progress and affect the result. In cases where compliance may be difficult or tooth movement is especially complex, braces may be the more predictable choice.
For children, stopping a thumb-sucking habit or addressing tongue posture may be part of treatment. In some situations, an orthodontic appliance can help discourage a persistent habit while guiding developing teeth and jaws. If speech or swallowing patterns are contributing, your orthodontist may recommend coordination with another qualified provider, such as a speech-language pathologist or myofunctional therapist.
Early treatment does not mean every child needs braces right away. Sometimes the most helpful plan is monitoring growth and checking in at the right intervals. An early evaluation gives families information before a developing issue becomes harder to manage.
When an open bite is primarily caused by a significant jaw discrepancy, orthodontics alone may not provide the best functional or stable outcome. In those cases, an orthodontist may discuss orthodontic treatment combined with jaw surgery. This is not the typical path for every adult open bite, but it can be the right one for certain skeletal cases.
It is a bigger commitment, with more planning and recovery time. It can also offer an important improvement in bite function when tooth movement alone cannot safely compensate for the jaw relationship. A candid conversation about benefits, limits, timing, and alternatives matters here.
Treatment time varies. A straightforward open bite involving mostly tooth position may improve in about 12 to 18 months, while more complex cases can take longer. Growth, treatment type, appointment attendance, aligner wear, and any ongoing habits all affect the timeline.
For families balancing school, work, and activities, the practical part matters too. Ask how often appointments are needed, whether evening or Saturday visits are available, and what home routines will help treatment stay on track. A plan should fit real life as well as your bite.
The day braces come off or the final aligner is completed is a milestone, not the end of care. Teeth can shift throughout life, and open bites can be particularly vulnerable to relapse if retainers are not worn as instructed.
Your orthodontist may recommend a removable retainer, a fixed retainer, or both. The exact plan depends on your bite and the treatment completed. Retainer wear is one of the simplest ways to protect the time, effort, and investment you put into your smile.
Consider an evaluation if front teeth do not meet, chewing feels inefficient, a child has a persistent thumb or pacifier habit, teeth appear to be shifting after past braces, or you are concerned about how your bite looks or feels. You do not need to know the diagnosis before making an appointment.
For West Hills and San Fernando Valley families, Chomp Orthodontics offers complimentary orthodontist-led consultations designed to make that first step feel straightforward. You can ask questions, review treatment choices, receive honest guidance, and understand the written cost estimate before committing to care.
A healthy bite should not feel like a puzzle you have to solve alone. Whether treatment begins now or later, a thoughtful orthodontic evaluation can replace uncertainty with a plan that feels clear, comfortable, and right for you or your child.
