When the teeth don’t align as they should, it is called malocclusion, or a bad bite. There are different classes of malocclusion, all of which can lead to orthodontic problems and dental issues. Our orthodontist in Chapel Hill explains the different classes below.

What Causes Malocclusion?

Malocclusion is usually caused by genetic factors. Hereditary markers can cause your jaw or teeth to grow abnormally in size or shape. However, it can also be caused by excessive thumb sucking, extra teeth, missing teeth, or jaw injury. Symptoms of malocclusion include mouth breathing, difficulty chewing and biting, speech difficulties, and jaw pain.

Classes of Malocclusion

There are 3 classes of malocclusion that define the type and severity of the misalignment.

Class 1 is the most common — the bite is normal, but the upper teeth slightly overlap the lower teeth.

Class 2 is also referred to as overbite, where the upper jaw and teeth overlap the bottom jaw and teeth.

Class 3 is known as underbite, where the lower jaw protrudes, causing the lower jaw and teeth to stick out, overlapping the upper jaw and teeth.

If malocclusion is not treated, it can lead to tooth decay, gingivitis, and other problems.

Treatments for Malocclusion

It’s critical to realign the teeth and jaws to restore proper occlusion and correct any abnormalities in facial appearance. Treatment options include:

  • Traditional metal braces, which are effective for all levels of malocclusion
  • Invisalign®, which is a great discreet option for mild to moderate cases
  • Removal of extra teeth
  • Replacing missing teeth 
  • Repairing damaged teeth or restorations

In severe cases, jaw surgery or stabilization may be necessary to correct malocclusion. If this is the case for you, our orthodontist will discuss this option during your appointment.
