Orthodontics

What is orthodontics?

Orthodontics is concerned with the normal and abnormal growth and development of the face, jaws and teeth.

Orthodontics is a special branch of dentistry that deals with the diagnosis, prevention and correction of dental and facial irregularities occurring as a result of:

  • A bad bite or malocclusion
  • Missing or extra teeth
  • Misaligned teeth
  • Crooked teeth
  • Crowed teeth
  • An overbite
  • An underbite
  • Misaligned or incorrect jaw position
  • A disorder of the jaw joint

Orthodontic irregularities are generally treated with as braces. Braces are usually made from wires and springs attached to tiny metal plates or a plastic mould. Braces apply gentle forces to teeth and encourage them to to move slowly to adopt a different alignment. The best orthodontic results are achieved with children when their teeth are still growing; many adults have orthodontic treatment, but the process takes much longer. Visit our main braces page to read more about how they work and how to look after them.

The orthodontist will assess the teeth that need to be aligned and create either a fixed or removable brace, which can be adjusted during the course of the treatment to achieve the desired effect. The fixed braces, as their name implies, are permanent fixtures and are removed at the end of the treatment period, whereas removable braces can be taken off for eating and cleaning but are generally worn at all other times. Braces will improve the function of the teeth and the general appearance of the person.

What is a bad bite or malocclusion and what causes it?

A bad bite is the misalignment of teeth, jaws or the tempromandibular joint (TMJ), which causes functional problems such as difficulty in chewing and talking, and may well affect the appearance of a person. It may occur genetically or as a result of the following conditions:

  • Trauma —fractured or knocked-out teeth in a growing child that, on replacement, fuses with the bone that surrounds them, resulting in an improper line up in the jaw

  • Prolonged thumb-sucking or pacifier use — can result in pronounced protrusion of upper teeth over the lower teeth.

  • Tongue-thrusting while swallowing — can result in pronounced protrusion of upper teeth over the lower teeth.

  • Premature loss of baby teeth — causing:
    • The permanent tooth to erupt incorrectly, resulting in crowded or partially erupted teeth.
    • The teeth next to the primary tooth to move into the vacant space and prevent the eruption of permanent tooth.

Why is orthodontic treatment crucial?

Beneficial in long-term dental health:
  • Properly aligned teeth are easier to maintain with proper oral hygiene.
  • Reduces the risk of tooth decay.

Improves chewing and digestion:

  • Since people with bad bites chew less efficiently, it can, in severe cases, result in nutritional deficiencies.

Improves speech:

  • Misaligned upper and lower teeth can cause speaking difficulties.

Prevents premature wearing of back-tooth surfaces:

  • Since the teeth withstand a tremendous amount of force when one bites down, in the case of people with improper bites, the back teeth are likely to wear out more quickly.

At what age can one start orthodontic screening and treatment?

  • Early childhood - you can have an orthodontic screening from the age of 7, by which time enough of the permanent teeth would have emerged, helping to identify potential problems. Do not wait for all the permanent teeth erupt in the mouth, as the earlier you start, the more the advantages.
  • During adolescent and teenage years – all permanent teeth would have come in by now, and treatment is most effective at this age
  • At adulthood - more complicated and often requires more than one dental professional to fully correct a problem.

What does orthodontic treatment involve?

There are two stages in orthodontic treatment
  • The active phase — which involves the use of braces or other appliances to correct the alignment and bite.
  • The retention phase —use of a retainer to hold the teeth that have been brought into their new position and ensure long-term results.


Orthodontics: Creating a Well-Aligned Smile

Years ago, orthodontic treatments were used only for pre-teens and teens having problems with their bite (malocclusion). Today, orthodontic treatments like dental braces are not only for pre-teens and teens, but for adults as well.

Close to 30 percent of all orthodontic patients in the United States are adults. Despite this growing trend towards adult orthodontics, it pays to start orthodontic treatment early for maximum effectiveness. The American Dental Association recommends that children receive an orthodontic evaluation by age seven.

The Restorative and Esthetic Nature of Orthodontics

Since malocclusion may interfere with eating and speaking, it is usually considered a restorative issue. Although, because a malocclusion may prevent the development of a beautiful, well-aligned smile or facial jaw lines, it may also be classified as an esthetic issue and categorized as cosmetic dentistry.

No matter what your age, orthodontics can protect your bite (occlusion), maximize your teeth's effectiveness in performing their functions and create a well-aligned smile. Today's orthodontics involves repositioning of the teeth and underlying roots, providing better support for the crown of the tooth. Orthodontic treatment is now associated with the benefits of greater esthetic appeal, increased comfort and reduced treatment time.

Orthodontic treatment can also rejuvenate your facial appearance by reshaping the jaw, neck and lips, especially when combined with maxillofacial surgical procedures. In addition, well-aligned teeth make oral hygiene easier to maintain.

The Orthodontic Evaluation

If you are a candidate for orthodontics, you will likely be referred by your general dentist to an orthodontist for evaluation of your bite. During your first orthodontic visit, your orthodontist may use several methods to develop an individualized treatment plan, including:

  • Oral, facial and functional evaluation (examination).
  • Intraoral and facial photographs.
  • Panoramic and cephalometric X-rays.
  • Impressions for models of the teeth and bite.

An orthodontist reviews your dental records, performs a clinical assessment, takes X-rays of your mouth and head and makes models of the teeth by creating an accurate impression of them. The results of this evaluation are studied in order to formulate the best orthodontic treatment plan.

Typically during the second visit, your orthodontist reviews the treatment plan and estimates the number of months for the active phase of treatment. The standard treatment phase is two years. Following treatment, you may be required to wear a retainer for a period of time.

The duration of orthodontic treatment varies based on your age, the extensiveness of the procedure (some people require more work than others) and how closely you follow your treatment plan. For example, younger patients may respond more quickly to treatment than older patients because the bones supporting young teeth are more pliable than those supporting older teeth. However, adults tend to follow treatment instructions more consistently than pre-teens.

Types of Braces

Metal Braces

Orthodontic treatment with standard nickel titanium braces






Ceramic Braces

Orthodontic treatment with ceramic material braces which have the same strengths but more aesthetic with its tooth tone color which similar to natural teeth


Self Legating Braces

Shorten treatment time with its self-legating ability and suitable for patient that known allergic to nickel or chromium with its fully titanium biomaterial
