Crowding and Spacing of Teeth

Crowding 

Crowding is the lack of space for all the teeth to fit normally within the jaws. The teeth may be twisted or displaced. Crowding occurs when there is disharmony in the tooth to jaw size relationship, or when the teeth are larger than the available space. Crowding can be caused by improper eruption of teeth and early or late loss of primary teeth. Crowding should be corrected because it can:

  • prevent proper cleaning of plaque removal on all the surfaces of your teeth.
  • increase the chances of gum disease and dental decay.
  • prevent proper functioning of teeth.
  • make your smile less attractive.

    How can crowding be orthodontically corrected?

    Extra space can be created by expansion of the arches or extraction of teeth. Once space is created, braces will eliminate crowding and align the teeth.

Spacing 

Spacing (the opposite of crowding), is an excess of space which results in gaps between your teeth. This generally occurs when the teeth are smaller than the available space. Spacing can also be caused by protrusive teeth, missing teeth, impacted teeth or abnormal tissue attachments to the gums.

Spacing should be corrected because it can:

  • result in gum problems due to the lack of protection by the teeth.
  • prevent proper functioning of the teeth.
  • make your smile less attractive.

How can spacing of the teeth be orthodontically corrected?

The spaces can be closed by moving the teeth together and properly aligning them within the arch.
