Why Straighten Teeth?

Straighter teeth perform chewing, biting and speaking functions more effectively than crooked teeth.  In addition, a straight smile boosts confidence, is aesthetically pleasing to look at, and can help stave off a wide variety of dental ailments.

There are several types of malocclusion including overbite, underbite, crossbite, and overcrowding.  Each of these alignment problems negatively impacts the functionality and cosmetic appearance of the teeth.

Here is a brief overview of some of the main disorders associated with crooked teeth:

Periodontitis – Periodontitis or gum disease begins with a bacterial infection.  The bacterial infection is caused by inadequate oral hygiene.  Crooked teeth are hard to clean effectively, which means that debris, plaque and bacteria can build up in hard-to-reach areas.  Straight teeth are much easier to clean and are at less risk of contracting gum disease.

Temporomandibular Disorder (TMJ) - Crooked teeth can lead to improper jaw alignment, which in turn causes a painful condition known as TMJ.  Severe headaches, jaw pain, lockjaw and the grinding of teeth characterize this debilitating disorder.

Tooth injury – Straight teeth creates a strong wall, which means injuries are less likely to occur.  Crooked teeth are weaker and often protrude, making them far more vulnerable to external injury.

Uneven wear – Crooked teeth cause some of the teeth to work harder than others when biting and chewing.  Straight teeth share the workload evenly, meaning less risk of injury and better aesthetics.


Reasons for orthodontic treatment:

  • Breathing or swallowing problems – Mouth breathing can lead to snoring and sleep apnea.
  • Crossbite – One or more upper teeth bite inside the lower teeth (towards the tongue).
  • Crowding – Involving extra teeth or malpositioned teeth.
  • Deep Overbite – The lower front teeth bite into the upper tissue of the upper teeth.
  • Disfiguring of the face & mouth – Affects the development of the jaw and position of the teeth.
  • Jaw & jaw joint pain
  • Missing or extra teeth – Due to tooth decay, injuries, or inherited problems.
  • Overjet (protruding upper teeth) – Upper teeth that protrude beyond normal and are usually associated with a short lower jaw.
  • Self-image – An attractive smile can boost a person’s self-image and confidence.
  • Spacing between teeth – Teeth are missing or may be too small or too large.
  • Speech, chewing or biting problems
  • Underbite (lower jaw protrusion) – Lower jaw is longer than the upper jaw

    Finger or thumb sucking – These habits can cause protrusion of the upper incisor teeth, and mouth breathing.
    Teeth erupting out of position – Can be guided to proper alignment.
