Airway, Growth & Early Orthodontics

Looking Beyond the Teeth

When we evaluate a growing child, we're looking at much more than whether the teeth are straight.

We're looking at the development of the jaws and palate, how the teeth are coming in, the bite, tongue position and function, oral habits, and how your child breathes and sleeps.

All of these things can affect how the mouth and face develop during childhood, which is why we believe they should be evaluated together.

Why Breathing and Oral Function Matter

Children should primarily breathe through their nose. When we see chronic mouth breathing, snoring, restless sleep, difficulty breathing through the nose, or a child who constantly rests with their mouth open, we want to know why.

We also pay close attention to the tongue. Where the tongue rests, how it moves and how a child swallows are all part of the functional environment in which the teeth and jaws are developing.

Sometimes what we find is primarily dental. Other times, we may recommend an evaluation with an ENT, physician, sleep specialist, myofunctional therapist, speech or feeding therapist, or another provider.

What Are We Looking For?

Some of the things that may catch our attention include:

• Mouth breathing or difficulty breathing through the nose
• Snoring, noisy breathing or restless sleep
• Lips that remain apart at rest
• A narrow or high palate
• Crossbites
• Crowding or lack of space for developing teeth
• Abnormal bite or jaw relationships
• Prolonged thumb, finger or pacifier habits
• Tongue thrust or low tongue resting posture
• Teeth grinding
• Enlarged tonsils or chronic nasal congestion
• Concerns with tongue mobility or oral restrictions
• Facial or jaw growth patterns that we want to monitor

Having one or even several of these findings does not automatically mean that something is wrong or that your child needs treatment. They simply tell us that we may need to look a little closer.

Why Consider Orthodontics So Early?

This is probably one of the most common questions we hear from parents.

“My child is only 4 or 5. Why are we already talking about orthodontics?”

Because at this age, we're not necessarily talking about braces or trying to straighten every tooth. We're evaluating how the jaws, palate, bite and dental arches are developing while your child is still actively growing.

There are certain problems that may be better addressed during growth rather than waiting until all of the permanent teeth have erupted.

That doesn't mean every child should be treated early. Many children are evaluated and simply monitored until the timing is right.

What Can Early Treatment Address?

Depending on the child, early treatment may be considered for concerns such as a narrow palate, crossbite, significant crowding, abnormal jaw relationships, harmful oral habits or other problems affecting dental and facial development.

Treatment may include palatal expansion, growth modification, habit correction, limited orthodontic treatment or other approaches based on your child's individual needs.

Early treatment also does not necessarily mean your child will never need braces or orthodontic treatment again. The purpose is to address problems that make sense to address now, while growth is on our side.

An Individual Approach

There isn't one appliance, one treatment plan or one “right age” that applies to every child.

We consider your child's age, stage of dental development, jaw growth, bite, oral function, habits, breathing and sleep history before deciding whether anything needs to be done.

Sometimes we recommend treatment. Sometimes we recommend another evaluation. And very often, we simply watch your child grow.

Our goal is to intervene when there is a reason to intervene, and not simply because we can.

how does your child sleep?

The answer is typically, "they sleep fine." Most parents do not sleep in the same room as their child, which is why Dr. Hannanvash takes a deep dive into your child's sleep structure. Having a bedtime routine, regulating screen time, and having a peaceful space for slumber are just a few things to consider. If you have these down pat and your little one is still waking you in the middle of the night, there are other signs Dr. Hannanvash will explore.

what are the signs?

breathing

If your child is not getting enough oxygen in their sleep, they are not getting enough oxygen to their brain. Abnormal breathing is an indication of potential airway obstruction. This may ultimately result in the following symptoms:

  • Snoring
  • Teeth grinding (bruxism)
  • Heavy breathing
  • Gasping/waking with a startle
  • Holding of breath
  • Mouth breathing

restless sleep

Your child may seem to sleep through the night, but that sleep might not be quality. If your child does the following, it may be an indication of poor quality sleep:

  • Toss and Turn
  • Wake in a tangle of blankets
  • Sleep in odd positions (head extended back, on their tummy with bottom up)
  • Have trouble falling asleep
  • Have trouble staying asleep
  • Wet the bed

behavior

A diagnosis of ADHD might actually be symptoms due to an underlying sleep issue. Children who do not reach their REM cycle will have impaired executive functioning skills, which includes working memory, cognitive flexibility, and inhibitory control. Here are a few of those symptoms:

  • Hyperactivity or fidgeting
  • Emotional or irritable behavior
  • Easily distracted
  • Daytime sleepiness
  • Difficulty focusing or hyperfocusing
  • Trouble with learning
  • Trouble with organizational skills

how to diagnose it

Pediatric sleep issues are complex and require accurate diagnosis. The signs are just a piece of the puzzle. If Dr. Hannanvash suspects the presence of abnormal breathing during sleep, she will want to find out what is causing the obstruction and will work with your ENT to explore the underlying cause. This requires a good understanding of your child's sleep environment, craniofacial structure and function. Dr. Hannanvash may use the following diagnostic tools to get the bigger picture:

  • Pediatric Sleep Questionnaire
  • Imaging (cone beam computed tomography or CBCT)
  • High resolution pulse oximetry (HRPO)
  • Orthodontic models
  • Oral motor functional assessment
  • Breathing assessment

surgeon

Dr. Hannanvash refers to the best ENTs who know how to work with children. Airway obstruction can occur at any level of the pharynx. It is imperative that nothing gets missed. Such obstructions may include:

  • Enlarged nasal turbinates
  • Enlarged adenoids
  • Enlarged tonsils
  • Tongue tie (or ankyloglossia)

therapist

Therapy is essential to establishing correct breathing habits before and after surgery. Dr. Hannanvash refers to therapists who will focus on properly establishing the following through myofunctional therapy and breathing retraining:

  • oral rest posture
  • lip seal
  • nasal breathing
  • deeper breathing

Research shows that palatal expansion will increase airway volume! For this reason, Dr. Hannanvash is able to provide early orthodontic services to help your child's craniofacial growth and development. Dr. Hannanvash keeps up with the most recent literature regarding early orthodontic intervention and believes it is vital to improving long term outcomes. Learn more under early orthodontics.

goals to treatment

Dr. Hannanvash ultimate goal is to help your child learn proper nasal breathing on their own during sleep. This means establishing:

  • Proper oral rest posture where the tongue is rested up against the palate
  • Lips sealed
  • Nasal breathing

It requires a full comprehensive treatment plan and a good team. Dr. Hannanvash makes it a point to work with the most experienced and knowledgeable providers in the field of pediatric airway.
