Malocclusions are “bad bites,” or incorrect relationships between the upper and lower jaw. Sometimes they may even be a general misalignment of the teeth. Malocclusions are very common, and most individuals will experience this problem to some degree. The misalignment of the teeth and jaws is considered to be a result of genetics combined with poor oral habits and other factors in the early childhood years.

There are three main classifications of malocclusion:

  • Class I – malocclusion caused by spacing or overcrowding of the teeth
  • Class II – malocclusion caused by an overbite (when the upper jaw is positioned forward)
  • Class III – malocclusion caused by an underbite (when the lower jaw is positioned forward)


Malocclusions may lead to disharmony of the lower face, as well as an increased risk of tooth decay, an increased risk of a TMJ (temporomandibular joint) disorder, and difficulty maintaining good oral hygiene with regular brushing and flossing. Malocclusions are typically treated with braces or other orthodontic appliances, such as Invisalign® clear aligners, retainers, headgear and palatal expanders. In more severe cases, an orthodontist may also work with an oral surgeon to resolve the problem and reconstruct or reposition the jaw.
