Can Orthodontic Expansion Help Children Avoid Ear Tubes?

 

Posted on 08/27/2026

Parents usually think of orthodontic treatment as a way to straighten teeth and improve a child's bite. But early orthodontic treatment can sometimes influence much more than tooth alignment. Research is continuing to examine how the development and width of the upper jaw may affect breathing, airway function and even the health of the middle ear. A recent study published in the European Journal of Pediatric Dentistry examined the relationship between orthodontics and chronic middle ear fluid, also known as otitis media with effusion (OME). Researchers found that rapid maxillary expansion (RME) may improve Eustachian tube function in certain children who have both chronic middle ear fluid and a narrow upper jaw.

For children who are appropriate candidates, this creates another reason an early orthodontic evaluation can be valuable.

What Does the Upper Jaw Have to Do with the Ears?

The Eustachian tubes connect the middle ears with the back of the throat. Their job is to help equalize pressure and allow fluid to drain from the middle ear.

When these tubes do not function properly, fluid can accumulate behind the eardrum. Persistent fluid may contribute to temporary hearing loss, recurring ear problems and, in some children, the recommendation for middle ear ventilation tubes. A narrow upper jaw or palate can be associated with changes in the surrounding anatomy and muscle function.

Rapid maxillary expansion is an orthodontic treatment designed to gradually widen the constricted upper jaw. Research suggests that expansion can also affect the muscles involved in opening the Eustachian tubes, potentially improving drainage and middle ear function.

What Does Research Show?

Research involving children with maxillary constriction and persistent middle ear fluid has produced encouraging results.

One clinical study compared children treated with rapid maxillary expansion with children receiving traditional middle ear ventilation tubes. Both groups demonstrated significant improvements in hearing, and researchers found similar improvements between the two treatments over the study period.

More recent research has continued to examine the relationship between orthodontic expansion and Eustachian tube function, supporting greater collaboration between orthodontists, pediatricians and ear, nose, and throat specialists.

This does not mean orthodontic expansion replaces ear tubes for every child.

It does suggest that, in appropriately selected children, the structure of the upper jaw may be one factor worth evaluating.

When Might Orthodontic Expansion Be Considered?

Rapid maxillary expansion is primarily an orthodontic treatment and is only appropriate when there is an orthodontic reason to widen the upper jaw.

A child may benefit from an orthodontic evaluation when there is:

  • A narrow upper jaw or palate
  • A crossbite
  • Crowding related to inadequate jaw width
  • Mouth breathing or airway concerns
  • Chronic Eustachian tube dysfunction
  • Persistent middle ear fluid
  • A combination of orthodontic and ear-related concerns

The original research specifically involved children with maxillary constriction. If a child's upper jaw is already developing normally, orthodontic expansion would not ordinarily be recommended simply to address an ear problem.

Why Early Evaluation Matters

Timing is important because orthodontists can often influence jaw development more effectively while a child is still growing.

The American Association of Orthodontists recommends that children receive their first orthodontic evaluation by approximately age seven. An early evaluation does not automatically mean treatment will begin at that age.

Instead, it gives the orthodontist an opportunity to evaluate:

  • Jaw growth
  • Upper jaw width
  • Bite development
  • Tooth eruption
  • Facial development
  • Airway-related concerns
  • The best timing for treatment is necessary.

For some children, identifying a narrow upper jaw early can create treatment opportunities that may become more difficult later in adolescence.

Orthodontists, Pediatricians and ENTs Working Together

Perhaps the most important message from this research is the value of a multidisciplinary approach. A child experiencing chronic middle ear fluid should continue to be evaluated by the appropriate pediatrician or ENT specialist. Ear tubes remain an important and well-established treatment when rapid drainage or hearing improvement is medically necessary.

However, when a child also has a narrow upper jaw, crossbite or other orthodontic developmental concerns, an orthodontic evaluation may provide another important piece of the puzzle.

Instead of looking at the teeth, jaw, airway and ears as separate systems, healthcare providers can work together to evaluate the child's overall growth and development.

Could Your Child Benefit from an Early Orthodontic Evaluation?

If your child experiences recurring or persistent middle ear fluid and you have also noticed a narrow smile, crossbite, crowding, mouth breathing or other concerns about jaw development, an orthodontic evaluation may be worthwhile. At Tollgate Orthodontics, we evaluate much more than whether the teeth are straight. Early orthodontic evaluations allow us to look at jaw development, bite relationships, facial growth, and airway-related factors while a child is still growing.

For the right child, addressing an underlying orthodontic problem early may provide benefits that extend well beyond the appearance of the smile.

Schedule an early orthodontic evaluation with Tollgate Orthodontics to learn whether your child's jaw and bite are developing properly.

Orthodontic treatment is not a substitute for evaluation or treatment by a pediatrician or ear, nose, and throat specialist. Children experiencing persistent ear fluid, the appropriate medical professional should evaluate hearing changes, pain, or recurring ear infections.

 

Frequently Asked Questions

Can orthodontic expansion help a child avoid ear tubes?

In some children, rapid maxillary expansion may improve Eustachian tube function and middle ear drainage when chronic ear fluid occurs along with a narrow upper jaw. It is not a replacement for ear tube surgery in every case, but research suggests it may be worth evaluating in appropriately selected children.

Can a narrow palate contribute to chronic ear fluid?

A narrow upper jaw or palate may be associated with changes in the anatomy and muscle function surrounding the Eustachian tubes. Because these tubes help regulate pressure and drain fluid from the middle ear, jaw development may be one factor to consider in children with persistent ear fluid.

What is rapid maxillary expansion?

Rapid maxillary expansion, or RME, is an orthodontic treatment used to gradually widen a constricted upper jaw. It is commonly used to address problems such as a narrow palate, crossbite, crowding, and certain developmental concerns while a child is still growing.

What age should a child have an orthodontic evaluation?

The American Association of Orthodontists recommends an initial orthodontic evaluation at approximately age seven. An evaluation at this age does not necessarily mean treatment will begin immediately. It allows the orthodontist to assess jaw growth, bite development, upper jaw width, tooth eruption, and other developmental factors.

Should a child with chronic ear fluid see an orthodontist?

If a child has recurring or persistent middle ear fluid along with a narrow upper jaw, crossbite, crowding, mouth breathing, or other concerns about jaw development, an orthodontic evaluation may be helpful. Children with ongoing ear problems should also continue to be evaluated by their pediatrician or ear, nose, and throat specialist.

Does orthodontic expansion replace treatment from an ENT?

No. Orthodontic treatment does not replace medical evaluation or treatment from a pediatrician or ENT specialist. Ear tubes remain an important treatment when rapid drainage or hearing improvement is medically necessary. Orthodontists, pediatricians, and ENTs can work together when both orthodontic and ear-related concerns are present.
