Bite problems

Overbite, underbite or crossbite: how our orthodontists decide whether aligners can correct it

The appliance comes last. First we find out whether the problem is in the teeth or the jaws, and whether growth is on your side.

How aligners correct each type of bite, with elastics, attachments and staged movements, is explained in the clear aligners for overbite guide at MapleRidgeClearAligners.com. This page covers the step before that: how a certified specialist orthodontist works out which tool your bite actually needs.

The three questions we answer at the evaluation

  1. Is the problem dental or skeletal? Teeth tipped out of position respond well to aligners. A jaw that sits too far forward, too far back or is too narrow is a different problem. Photographs, the scan and, when indicated, an x-ray tell us which one you have.
  2. Is the patient still growing? In children and teens, jaw growth can be guided. In adults it cannot, so skeletal problems are camouflaged, accepted or corrected surgically.
  3. Is something else driving the bite? Mouth breathing, a tongue thrust, a thumb habit or jaw joint symptoms all change the plan. We screen for breathing and airway concerns at every assessment.

What we typically recommend

What we findOur usual recommendation
Mild to moderate deep overbiteAligners, which handle these well
Upper teeth sticking out (overjet) in a growing teenAligners with elastics, or braces, timed to use growth
Mild dental underbite or a single-tooth crossbiteAligners, sometimes with elastics
Narrow upper jaw in a childA palatal expander in early treatment, with aligners or braces later
Mild open bite in an adultAligners, often a good tool for this
Severe deep bite with heavy wear, or an open bite from a tongue habitBraces or a combination, sometimes with myofunctional therapy
Significant skeletal underbite or overjet in an adultOrthodontics combined with jaw surgery, whichever appliance is used

A guide, not a diagnosis. The recommendation for your bite comes from your own records.

When we recommend braces instead

When the movement your bite needs is one aligners do less predictably, or when we doubt the daily wear will happen. Sometimes the answer is both: braces for a few months to do the difficult part, then aligners to finish. Braces or Invisalign: how we decide sets out that reasoning.

Why children are assessed early

A crossbite or a jaw growing in the wrong direction is far easier to guide at 8 than to correct at 28. That is why a first orthodontic check by about age 7 is recommended, and why an adult's skeletal bite problem has fewer options. See what age a child should first see an orthodontist.
