What is Malocclusion of the Teeth?

Malocclusion of the teeth refers to the misalignment of your teeth. It may cause problems such as an improper smile or flawed jawline and interfere with eating and speaking. It is also called by the names:

  • Crowded or crooked teeth
  • Overbite/underbite

The degree of malocclusion varies from person to person. The common approaches to treat malocclusion/misalignment of your teeth are braces and teeth removal.

What are the Problems Associated with Malocclusion/Misaligned Teeth?

Malocclusion or misaligned teeth need to be corrected for aesthetic reasons. A person may develop low self-esteem due to their appearance which can affect their quality of life. In addition, crooked teeth may cause tooth decay or tooth loss. People with a severe underbite or overbite may develop eating or speech problems.

What are the Different Types of Malocclusions/Misalignments of the Teeth?

Malocclusion/misalignment of the teeth is classified into three types:

Class 1 Malocclusion/Normal

In this type of malocclusion, the upper teeth overlap the lower teeth. Your bite remains normal and the overlap is slight. It is the most common type of malocclusion.

Class 2 Malocclusion/Severe overbite

In this type of malocclusion, the upper teeth and jaw significantly overlap the lower jaw and teeth. This condition is characterized by a severe overbite.

Class 3 Malocclusion/Severe underbite

In this type of malocclusion, the lower jaw protrudes forward and causes the lower teeth to overlap the upper teeth and jaw. This is a case of a severe underbite.
