What are “crowded teeth”?

“Crowded teeth” is a common orthodontic condition that occurs when there is insufficient space in a patient’s mouth. This causes the teeth to rotate and overlap each other – hence the term “crowded” teeth.

Crowded teeth can cause a number of problems, including oral health problems and self-esteem issues. Fortunately, we can treat this condition through orthodontic treatment!

Here’s what you need to know:

What causes crowded teeth?

Genetics is the most common reason why some people develop crowded teeth. The teeth may be disproportionately larger than the jaw, the jaw bones may be underdeveloped, or the jaw bones are too narrow to provide enough space for the teeth.

What can crowded teeth lead to?

Depending on whether it’s a case of mild crowded teeth or severely overcrowded teeth, crowding teeth can lead to a number of conditions, including:

  • Gum disease & tooth decay – It’s difficult to properly brush and floss all surfaces of crowded teeth, which can lead to gum disease and tooth decay.
  • Digestive issues – It may be difficult to chew food sufficiently with crowded teeth, which can cause poor digestion and an upset stomach.
  • Speech impediment – Misaligned teeth may cause the mispronunciation of words and affect speech patterns.

How to Fix Crowded Teeth

There are a few crowded teeth treatment options through orthodontics.


Braces are the most common appliance used to fix overcrowded teeth among children and adults. Usually, this treatment method is suggested for moderate to severe cases of crowded teeth. Braces will likely be worn for at least a year, followed by a retainer after treatment to avoid teeth from shifting back into their original position.

Clear Aligners

Invisalign clear aligners and Spark clear aligners are alternatives to braces! Clear aligners work similarly to braces by exerting gradual, gentle force to move the teeth into place. Clear aligners are made of high-technology plastics, custom-designed to fit each patient’s smile. This treatment may be suitable for adults with mild to moderate cases of overcrowding. (And a bonus benefit—with transparent aligners, nobody will know you’re undergoing treatment!)

Tooth Extractions

Extraction of select teeth may be the most effective way to make more space in a crowded mouth for severe cases. If necessary, this procedure will be performed by a dentist and is done prior to wearing braces.
