What are crowded teeth?

If there is too little space in the jaw for the teeth or if they are too big or too wide in relation to the jaw, they can overlap. There are many causes of overcrowded teeth. Contrary to what many people think, it's not the wisdom teeth that are usually responsible for crowding. Growth-related and genetic factors play a considerable role.

Causes of dental crowding

  • Teeth too big or wide compared to the size of the jaw
  • Narrow jaws
  • Premature loss of baby teeth, with adult teeth growing into the gaps
  • Imbalance between the tongue, cheek and lip muscles

Why correct crowded teeth?

It's often difficult or impossible to practice good oral hygiene if the teeth are overlapping. It's also not aesthetically ideal to have crowded teeth, leading many people to feel self-conscious about laughing or smiling.


  • Asymmetric wear and tear on teeth
  • Reduced ability to clear one's teeth
  • Impaired oral hygiene increases risk of cavities, gingivitis and periodontitis


  • Unharmonious smile

Everyday issues

  • Mental health issues due to feeling self-conscious about laughing or smiling

How Aligners correct crowded teeth

In most cases, crowded teeth can be corrected with removable braces. How it works:

  • Every 2 weeks you switch to a new Aligner tray.

  • play

    Each Aligner tray pushes the teeth slightly more in the desired direction.

  • Your crowding issues will be slowly and gently corrected over a period of 3 to 12 months.

Crowded teeth FAQs

Is it possible to correct crowded teeth without using braces?

Extend Extend

It's necessary to use either orthodontic treatment or dental extractions to correct crowded teeth. In many cases, crowding can be successfully treated with conventional braces or with Aligner treatment. First, space needs to be created between the teeth so that they have room to move into the right position. This is known as slicing, or interproximal enamel reduction (IPR).

Is it possible to correct crowded teeth without slicing or enamel reduction?

Extend Extend

Very slight crowding of the front teeth can be corrected to a certain extent without slicing, depending on the patient's situation – for instance via tilting the teeth or slightly expanding the dental arch. Usually these techniques are done in combination with gentle tooth slicing or stripping, however.

Slicing is an alternative to dental extractions. Conventional treatment methods with metal braces often involve the extraction of several teeth to make sufficient room for teeth to move. At bestsmile, this is usually not necessary. We prefer gentle interproximal reduction, which can create the space needed to correct your bite.

The mini-gap created by dental slicing is not visible to the naked eye and will be closed over the course of the Aligner treatment. A fine polishing strip is used to remove a minimal layer of the enamel surface.

Does health insurance cover treatment for crowded teeth?

Extend Extend

This depends on the severity of the malocclusion and the terms of your insurance policy. You should contact your insurer directly for more information.
