Types of Bad Bites and Their Treatments


What is a bad bite? A bad bite, also called a malocclusion, is when the upper and lower teeth don’t fit together the way they should.

Depending on the type of malocclusion, this can cause a variety of problems, from impacting speech to making digestion less efficient to worsening TMD troubles, and they can even increase the risk of breaking a tooth!

What Makes a Bite Go Bad?

Malocclusions happen for different reasons. Some are caused by genetics. If a child inherits large teeth from Dad and a small jaw from Mom, there’s a good chance their teeth won’t be able to fit together well. Other causes include injuries and bad oral habits in the developmental years, including thumbsucking, lip sucking, tongue thrusting, nail biting, mouth breathing, and teeth clenching.

By discouraging these kinds of bad habits, parents can help their children grow up with healthier bites. If one of these habits does cause a malocclusion, it’s still important to break the habit so that bite problems don’t come back after orthodontic treatment. Luckily, we can help with that.

Different Types of Malocclusions

When the teeth and jaws are aligned correctly, the upper teeth rest slightly over the lower teeth while the jaw is closed, and the points of the upper molars fit nicely into the grooves of the lower molars. Here are the five most common ways a bite can differ from this healthy ideal:

  • Open Bite. The front upper teeth flare out, creating a gap between them and the lower front teeth even when biting down. (Can be caused by thumbsucking beyond toddler years or a tongue thrust.)
  • Underbite. When biting down, the lower teeth overlap or partially cover the upper teeth.
  • Crossbite. Some upper teeth bite down on the inside of the lower teeth while others bite down on the outside.
  • Excessive Overbite. The upper teeth overjet or overlap the lower teeth beyond what we want to see in a healthy bite.
  • Deep Bite. An overbite so severe that, when biting down, the upper front teeth completely overlap the lower front teeth, which sometimes drive into the gums behind the upper teeth, risking gum injury and other problems.

Fixing Malocclusions with Orthodontic Treatment

Each of these types of malocclusions and others can be corrected through orthodontic treatment. Now, before you start picturing bulky headgear, remember that the field of orthodontics has come a long way. Surgery and headgear are still sometimes necessary for extreme cases, but we can typically correct a bad bite in very low profile and hassle-free ways.
