A pediatric dentist’s guide to the signs, causes, and when to see an orthodontist.
Jaw alignment can influence how a child’s teeth line up, how their face grows, and everyday functions like eating, speaking, and breathing. Knowing what to look for helps you act while your child is still growing.
Common signs of a jaw alignment issues in kids include crowded teeth, chewing difficulty, mouth breathing, jaw clicking, and an uneven bite. Early evaluation lets specialists guide jaw development while a child is still growing, which can reduce the need for more complex treatment later. Your pediatric dentist screens for early signs at regular visits and refers you to an orthodontist when orthodontic care is the right next step.
At Lake Sammamish Kids Dentistry in Sammamish, WA, Dr. Annikka Freelove watches for early signs of jaw and bite concerns at regular visits and works with local orthodontists and other specialists. When orthodontic care is the right next step, she refers families to Dr. Cameron Freelove at Freelove Orthodontics, with locations in Sammamish and Kent, WA.
Jaw alignment problems often have more than one cause, from genetics and childhood habits to airway issues and injuries, so the first step is a careful look at the whole picture.
This guide covers the common types of jaw alignment problems, the signs to watch for, what causes them, and when it makes sense to see an orthodontist.
What Are Jaw Alignment Issues in Children?
Jaw alignment issues happen when the upper and lower jaws or teeth do not line up in a healthy way. Dentists often call this jaw misalignment or malocclusion, and it can range from mild to more serious.
There are two main kinds of problems:
- Dental problems involve the teeth, such as crowding, spacing issues, or teeth that tip in or out.
- Skeletal problems involve the bones of the face and jaws, including growth issues where one jaw is too far forward, too far back, or too narrow.
As children grow, their jaws and teeth change. Normal growth helps the teeth and jaws come together in a balanced way, but jaw development issues can leave the bite uneven. That can lead to bite misalignment such as overbites, underbites, crossbites, and open bites.
Common Types of Jaw Alignment Problems
Several common jaw alignment problems can affect chewing, speaking, and comfort.
Overbite and Overjet
An overbite happens when the upper front teeth cover too much of the lower front teeth when your child bites down. An overjet is when the upper front teeth stick out far past the lower front teeth. Both can make it harder to bite into foods and may affect a child’s smile and confidence.
Underbite
An underbite happens when the lower teeth sit in front of the upper teeth. This is often due to a lower jaw that is too large or an upper jaw that is too small. Over time, an underbite can lead to jaw pain, tooth wear, and chewing problems.
Crossbite
A crossbite happens when some of the upper teeth bite inside the lower teeth instead of outside. It can affect the front teeth, the back teeth, or both, and it can cause uneven jaw growth, facial asymmetry, and extra wear on certain teeth.
Open Bite
An open bite happens when the upper and lower front teeth do not touch when your child bites down, leaving a gap between them. It can make biting into foods and speaking clearly more difficult, and it is often related to habits like thumb sucking, prolonged pacifier use, or tongue thrusting.
Each of these problems can affect your child’s ability to chew, speak, and smile with ease.
Bite Problems at a Glance
| Problem | What It Looks Like | What It Can Affect |
| Overbite | Upper front teeth cover too much of the lower front teeth when biting down | Biting into foods, smile, confidence |
| Overjet | Upper front teeth stick out far past the lower front teeth | Biting into foods, smile, confidence |
| Underbite | Lower teeth sit in front of the upper teeth, often from a large lower jaw or small upper jaw | Jaw pain, tooth wear, chewing |
| Crossbite | Some upper teeth bite inside the lower teeth, in the front, back, or both | Uneven jaw growth, facial asymmetry, extra tooth wear |
| Open bite | Upper and lower front teeth do not touch when biting down | Biting into foods, clear speech; often linked to thumb sucking, prolonged pacifier use, or tongue thrusting |
Signs of Jaw Alignment Issues to Watch For
It can be hard to know what is normal when it comes to jaw growth. The good news is that there are clear signs you can look for at home.
Facial and Physical Signs
- Asymmetry in the face, where one side of the jaw looks different from the other
- A chin that sticks out too far or not far enough
- Mouth breathing or an open-mouth posture, even when your child is resting
- Trouble closing the lips comfortably without strain
These signs can point to jaw development or jaw growth issues that may need an evaluation.
Dental Signs
- Crowding of the teeth, meaning not enough space
- Spacing issues, such as gaps between the teeth
- Teeth that do not fit together well when your child bites down
- Teeth that seem to tilt in different directions
- Early or delayed tooth loss compared to other kids their age
These warning signs can show that the jaws and teeth are not working together in a balanced way.
Functional and Behavioral Signs
- Chewing difficulties, like taking a long time to chew or avoiding certain foods
- Speech difficulties, such as lisping or trouble pronouncing certain sounds
- Clicking or popping sounds in the jaw when chewing or opening wide
- Teeth grinding (bruxism), especially at night
- Jaw clenching, during the day or at night
- Frequent headaches, jaw pain, or earaches
- Jaw stiffness or pain with opening, which can be a sign of temporomandibular joint (TMJ) issues
If you notice several of these symptoms, it may be time to schedule an examination and consultation.
What Causes Jaw Alignment Issues in Kids?
Jaw alignment problems often have more than one cause. Common factors include:
- Genetics and family history: If a parent has an underbite, overbite, or another bite problem, a child may be more likely to have one too.
- Thumb sucking and pacifier use: When these habits last past age 3 to 4, they can push teeth and jaws out of position and lead to an open bite or overjet.
- Tongue thrusting: When the tongue pushes forward between the teeth during swallowing or at rest, it can affect jaw development and front tooth position.
- Airway issues: Large tonsils, adenoids, or chronic allergies can lead to mouth breathing. Over time, this can change the growth patterns of the jaw and face.
- Trauma or injury: A fall or a hit to the jaw can affect how the jaw bones grow and fit together.
Dr. Annikka considers all of these possible causes when evaluating your child’s bite and jaw development.
Why Early Evaluation Matters
Early evaluation is one of the most important steps you can take for your child’s smile and overall health. The benefits of early intervention include:
- Interceptive orthodontics can guide jaw and tooth growth while your child is still growing.
- It can reduce the need for more complex or invasive treatments, like jaw surgery, later on.
- Early treatment options may improve your child’s chewing, speech, and breathing.
- It can support healthy jaw development, facial balance, and self-confidence.
By checking for jaw alignment issues at a young age, concerns can often be addressed before they turn into bigger bite misalignment and jaw development issues in the teen years.
How Jaw Alignment Issues Are Treated
Treatment depends on your child’s age, growth stage, and jaw needs, and orthodontic treatment is planned and provided by an orthodontist. Pediatric dentists and orthodontists in Sammamish work together to choose the best plan.
Growth Modification Treatments
For growing children, an orthodontist may use special tools that gently guide jaw growth:
- Palatal expanders widen the upper jaw to fix a narrow arch or crossbite and create more room for incoming teeth.
- Other functional appliances help shift the jaw into a better position, especially in cases of underbites or overbites.
These devices work best while your child is still growing, which is why early intervention is so valuable. According to Dr. Jiayu (Fiona) Shi, a board-certified orthodontist at Emerald City Orthodontics in Kirkland, WA, guiding jaw growth while kids are young can help the upper and lower jaws match better and make teen braces much easier.
Orthodontic Treatment
Some children need more direct orthodontic care:
- Braces move teeth into better positions and improve the bite. They can also help correct some malocclusion and bite issues linked to jaw growth.
- Aligners: In some older kids and teens, clear aligners can help fix mild to moderate alignment problems.
When Orthodontic Treatment Alone Isn’t the Whole Answer
Jaw alignment is often a team effort, and some concerns need another specialist alongside or before an orthodontist. Dr. Annikka may coordinate with:
- ENT doctors (ear, nose, and throat specialists) to address airway or breathing issues
- Speech therapists to help with speech difficulties that come from bite or jaw problems
- Other dental specialists to manage TMJ issues or temporomandibular joint disorders when needed
This collaborative care helps create a complete plan to support jaw health, facial growth, and function.
When Should Your Child See an Orthodontist?
Consider an earlier consultation if you notice:
- Early or very late loss of baby teeth
- Difficulty biting or chewing
- Mouth breathing most of the time
- Jaw pain, clicking, or popping
- Chronic headaches or earaches
- Clear asymmetry in the face or bite
A screening visit with Dr. Annikka is a good first step. She can look at your child’s bite and jaw development and help you decide whether an orthodontic evaluation is the right next move.
What a Screening Visit Can (and Can’t) Tell You
During a visit in Sammamish, WA, you can expect a gentle examination, child-friendly X-rays if needed, and a clear talk about your child’s jaw alignment concerns. Dr. Annikka explains what she sees, what it means, and any next steps. The goal is to make both kids and parents feel at ease and well informed.
What a screening visit can’t do is replace an orthodontic treatment plan. It can flag early signs and point you toward the right specialist, but diagnosing the specific jaw problem and planning braces or other orthodontic care happens with an orthodontist, and no single visit can predict exactly how a child’s jaws will keep growing.
If you’ve noticed any signs of jaw alignment issues in your child, don’t wait to seek help. Schedule a jaw alignment evaluation today to give your child the best chance for proper jaw development, improved function, and a confident, healthy smile.

FAQs: Jaw Alignment Issues in Kids
What are the signs of jaw alignment issues in children?
Jaw alignment problems can show up in different ways. Watch for facial asymmetry, a chin that sticks out or is recessed, mouth breathing, or trouble closing the lips comfortably. Dental signs include crowded or spaced teeth, teeth that don’t fit together when biting, and early or delayed tooth loss. Functional signs can include chewing difficulties, speech issues, jaw clicking or popping, teeth grinding, jaw clenching, and frequent headaches or earaches. Noticing these symptoms early helps guide proper jaw growth.
What causes jaw alignment problems in kids?
Jaw alignment issues often have multiple causes. Genetics can play a role if a parent has bite problems. Prolonged habits like thumb sucking, pacifier use, or tongue thrusting can affect jaw development. Airway issues, such as enlarged tonsils or chronic allergies, can lead to mouth breathing that changes jaw growth. Trauma or injuries to the jaw can also affect alignment. Early evaluation helps identify the causes and guide next steps.
How are jaw alignment issues treated in children?
Treatment depends on the child’s age and growth stage and is planned by an orthodontist. Early intervention may involve growth modification tools like palatal expanders or functional appliances to gently guide jaw development. Orthodontic treatments such as braces or clear aligners can correct bite and alignment issues. Collaborative care with ENT specialists, speech therapists, or other dental providers may also be recommended to address airway, speech, or TMJ concerns.
Can thumb sucking or pacifier use affect my child’s jaw alignment?
Yes. When thumb sucking or pacifier use continues past age 3 to 4, it can push teeth and jaws out of position and lead to an open bite or overjet. Tongue thrusting can also affect jaw development and the position of the front teeth. If your child has any of these habits, mention them at your next visit so they can be taken into account.
Who treats jaw alignment problems, and what does my pediatric dentist do?
Braces and other orthodontic treatment are provided by an orthodontist. At Lake Sammamish Kids Dentistry, Dr. Annikka screens for early signs of jaw and bite concerns and coordinates with local orthodontists and other specialists.
