Why consult from age 7?

At age 7, the first permanent molars appear and the bite begins to take shape. This is the ideal time to detect any growth or alignment problems.

Early interceptive treatment can prevent future complications and significantly reduce the duration and complexity of later orthodontic treatment.

Dr Benguira has unique expertise acquired over 15 years at Sainte-Justine Hospital, specializing in treating children of all ages.

What we evaluate

During the first consultation, Dr Benguira thoroughly examines several aspects of your child's dental and facial development:

  • Jaw growth to detect any imbalance between the upper and lower jaws
  • Available space to ensure all permanent teeth can emerge properly
  • The bite how the upper and lower teeth fit together
  • Habits thumb sucking, mouth breathing, atypical swallowing or tongue thrust (pushing the tongue against the teeth when swallowing)

This early evaluation allows us to intervene at the optimal time to guide growth and simplify future treatment.

The two-phase treatment

Interceptive orthodontics allows us to intervene when your child's growth is our greatest ally. Instead of waiting for all problems to develop, we act in two strategic phases for optimal results.

1 Phase 1 – Interceptive orthodontics

Age: Between 6 and 9 years old, while the jaw bones are actively growing.

Duration: 6 to 18 months depending on the problem to correct.

The goal of Phase 1 is not to perfect the final alignment, but to create ideal conditions for permanent teeth to grow in correctly. At this age, the bones are still malleable and respond very well to orthopedic appliances.

Problems treated in Phase 1:

  • Narrow palate palatal expansion to create the necessary space
  • Crossbite correction of lateral jaw misalignment
  • Prognathism the lower jaw extends beyond the upper
  • Retrognathism the lower jaw is too far back compared to the upper
  • Persistent habits thumb sucking, mouth breathing
  • Severe space shortage to avoid future extractions

2 Phase 2 – Complementary treatment

Age: During adolescence, once all permanent teeth are in place.

Duration: Generally shorter thanks to Phase 1.

Phase 2 aims to perfect the final alignment of all permanent teeth and optimize the bite. It uses fixed brackets (braces) or clear aligners.

Thanks to the work done in Phase 1, this treatment is often:

  • Shorter the foundation is already in place
  • Simpler fewer complex corrections to make
  • Less invasive extractions and surgery often avoided

💡 Good to know: Between the two phases, an observation period allows us to monitor growth and permanent teeth eruption. No appliance is worn during this period.

The advantages of two-phase treatment

Avoid surgery

By guiding jaw growth early, orthognathic surgery in adulthood can often be avoided.

Create space

Palatal expansion in children is simple and effective. It creates space for permanent teeth and improves nasal breathing.

Improve function

Chewing, breathing and speech are optimized. Some children even see their school focus improve.

Protect teeth

Protruding teeth are vulnerable to trauma. Early correction significantly reduces the risk of dental fracture.

Appliances used in interceptive orthodontics

Based on your child's diagnosis, Dr Benguira will choose the best-suited appliance to correct the problem at the optimal time during growth.

🦷 Palatal expansion

The rapid palatal expander (RPE) is one of the most commonly used appliances in pediatric orthodontics. Fixed to the palate, it gradually widens the upper jaw by acting directly on the palatal suture, which is still flexible in children.

Indications:

  • Narrow palate creating space for permanent teeth
  • Crossbite correcting lateral misalignment between the jaws
  • Dental crowding avoiding future extractions by creating space
  • Mouth breathing improving nasal airflow by widening the nasal floor

💡 Good to know: Palatal expansion is only effective in growing children. In adults, the suture is fused and a surgical approach may be necessary. This is why it is crucial to intervene at the right time.

🦷 Space maintainer

When a child loses a baby tooth prematurely (cavity, trauma), the adjacent teeth can drift and block the space meant for the permanent tooth. The space maintainer prevents this problem.

Types of maintainers:

  • Band-loop fixed on the adjacent tooth with a wire maintaining the space (most common)
  • Lingual arch fixed on both lower molars to preserve bilateral space
  • Nance arch similar to the lingual arch, but for the upper jaw

Result: the permanent tooth erupts normally in the preserved space, avoiding dental crowding and more complex orthodontic treatment.

🦷 Face mask (protraction mask)

The face mask is an extra-oral appliance used to correct prognathism (skeletal Class III) in growing children. It stimulates upper jaw growth by pulling it forward.

How it works:

  • An appliance fixed to the palate is connected by elastics to the mask worn on the face
  • The elastics exert a forward pulling force on the upper jaw
  • Worn 12 to 14 hours a day, mainly in the evening and at night

Results:

  • Upper jaw advancement to correct the discrepancy
  • Improvement of facial profile and aesthetics
  • Avoiding orthognathic surgery in adulthood in many cases

💡 Treatment window: The face mask is most effective between ages 7 and 10, when upper jaw growth can still be stimulated. After puberty, this option is no longer available.

🦷 Tongue thrust

Tongue thrust is a habit where the child pushes their tongue against the front teeth when swallowing. This repeated force (we swallow more than 1,000 times a day) can cause significant deformities.

Consequences of tongue thrust:

  • Anterior open bite teeth don't touch at the front
  • Incisor protrusion upper teeth are pushed forward
  • Lisping pronunciation difficulties
  • Treatment failure if the thrust is not corrected, relapse is frequent

Our approach: We identify tongue thrust from the initial consultation. Myofunctional re-education exercises combined, when needed, with an orthodontic appliance (lingual crib or Bluegrass appliance) help correct this habit and ensure treatment stability.

When to consult quickly?

Some signs warrant an orthodontic consultation without waiting until age 7. If you notice any of these problems, book an appointment quickly:

  • Jaw deviation your child's chin is off-center to the left or right
  • Lower jaw too far forward the lower teeth extend beyond the upper teeth
  • Significant open bite the upper and lower teeth don't touch even when the mouth is closed
  • Severe crowding significant lack of space for permanent teeth
  • Difficulty eating or speaking related to a bite problem

Early intervention can avoid heavier and longer treatments during adolescence.

What parents ask us

About the first visit

No, it's never too early if you have concerns. Although the recommended age is 7, some problems warrant an earlier consultation, such as a deviated jaw, an open bite or persistent thumb sucking. An evaluation helps determine the optimal time to intervene.

Yes, absolutely. The initial orthodontic consultation is free with no obligation. It allows us to get acquainted, examine your child and discuss your concerns. If additional tests are needed (X-rays, 3D scan), they will be offered at a subsequent appointment with a cost estimate.

If interceptive treatment is recommended, we will present a detailed plan including the objectives, estimated duration, proposed appliances and costs. You will have all the time you need to ask your questions and make an informed decision. We never start treatment without your full consent.

About the treatment

Modern orthodontic treatments are designed to be comfortable. There may be slight sensitivity during the first few days after placing an appliance or after an adjustment, but it is generally minor and resolves quickly. We use modern techniques and materials to minimize discomfort.

Duration varies depending on the nature of the problem. Early interceptive treatment can last 6 to 18 months, while complete treatment with braces during adolescence generally lasts 18 to 24 months. Early treatment can often reduce the duration and complexity of future treatment.

Special needs

Yes, absolutely. Dr Benguira has extensive experience treating children with ADHD, autism, Down syndrome and other special needs, acquired during his 15 years at Sainte-Justine Hospital. We adapt our approach, appointment duration and appliances used to ensure comfort and treatment success.
