Orthodontics

Orthodontics is the dental specialty focused on correcting irregularities in the teeth and jaw. When teeth are crowded, spaced too far apart, or misaligned, or when the upper and lower jaws do not sit together correctly, orthodontic treatment can bring them into proper position.

Treatment typically involves braces, clear aligners, or jaw appliances, and lasts anywhere from 6 months to 2 years depending on the complexity of the case. Beyond aesthetics, orthodontic correction reduces the risk of tooth decay, gum disease, and long-term jaw problems. This guide covers what orthodontics treats, how treatment works, what the options are, and when to start.

What Conditions Does Orthodontics Treat?

Orthodontics addresses a wide range of dental and jaw irregularities. Some are primarily aesthetic, while others have a direct impact on chewing function, speech, and long-term oral health. The table below covers the most commonly treated conditions.

How Is Orthodontic Treatment Performed?

Orthodontic treatment follows a structured process from initial assessment through to retention. The specific approach depends on the type and severity of the problem, the patient’s age, and whether fixed or removable appliances are most appropriate.

Examination and Treatment Planning

Treatment begins with a comprehensive assessment of the teeth, jaw, and facial structure. Panoramic X-rays and cephalometric films are taken to evaluate bone structure and tooth positions. Digital impressions or 3D models may also be made. From this data, the orthodontist develops a detailed treatment plan that maps out the sequence and method of tooth and jaw movement.

Active Treatment

The active phase of treatment involves wearing the prescribed appliance consistently over a period of months or years. The orthodontist monitors progress at regular appointments — typically every four to eight weeks — and makes adjustments as needed. The duration of this phase varies from around six months for simple cases to two years or more for complex ones.

Retention

Once active treatment is complete, retainers are worn to hold the teeth in their new positions. Without retention, teeth have a natural tendency to drift back toward their original alignment over time. Retainers may be fixed — a thin wire bonded to the inside of the teeth — or removable, worn at night. Your orthodontist will advise on the appropriate type and duration based on your case.

Orthodontic Treatment Methods

Several different appliances and techniques are used in orthodontics, each suited to different situations and patient needs.

Metal Braces

Metal braces are the most established and widely used orthodontic appliance. Brackets are bonded to the front surface of each tooth and connected by a wire that applies controlled pressure to move the teeth gradually. Because they are fixed in place, there is no compliance issue — the appliance works continuously.

Metal braces are the most effective option for complex cases involving significant crowding, bite correction, or jaw movement. They are also the most cost-effective choice. The main drawback is their visibility, though many patients — particularly children and teenagers — adapt to them quickly.

Ceramic (Clear) Brackets

Ceramic brackets work in the same way as metal braces but use tooth-coloured or clear materials that blend with the natural tooth shade. They are a more discreet alternative to metal brackets while offering similar effectiveness. They are slightly more prone to staining over time and typically cost more than standard metal braces.

Lingual Braces

Lingual braces are attached to the inside surface of the teeth rather than the front, making them completely hidden from view. They are a highly discreet option for patients who cannot use clear aligners but want an invisible appliance. Lingual braces require more adjustment time initially, as the tongue needs to adapt to the appliance, and they are generally more expensive than conventional braces.

Clear Aligners

Clear aligners use a series of custom-made removable trays to move teeth incrementally. Each tray is worn for one to two weeks before being replaced by the next in the series. Because they are removable, eating and cleaning the teeth remain straightforward throughout treatment.

Clear aligners are best suited to mild to moderate cases. They require strong patient commitment — the trays must be worn for 20 to 22 hours per day to be effective. They are not suitable for all cases, particularly those involving significant jaw correction or complex bite issues.

Removable Plates and Functional Appliances

Removable appliances are most commonly used in children to guide jaw development during the growth phase. Functional appliances redirect jaw growth — for example, encouraging the lower jaw to develop forward, or restraining excessive growth. Palatal expanders widen the upper jaw in children with a narrow arch, creating space for the developing teeth.

These appliances are most effective while the jaw is still growing, which is why early assessment at age 7 is recommended. By the time growth is complete, the window for influencing jaw development with removable appliances has largely closed.

Jaw Masks (Face Masks)

A jaw mask is an external appliance worn over the face to encourage forward development of the upper jaw in cases where it is underdeveloped relative to the lower jaw. It is used primarily in children and works by applying gentle forward traction to the upper jaw during the growth period. Like other functional appliances, it is most effective when started early.

When Should Orthodontic Treatment Begin?

Permanent teeth begin to emerge around age 6 and are typically fully developed by ages 12 to 13. The American Association of Orthodontists recommends that children have their first orthodontic assessment by age 7. At this age, enough permanent teeth have emerged to identify developing problems, but the jaw is still growing — making early intervention possible where it is needed.

The most common window for comprehensive orthodontic treatment is between ages 12 and 14, when the last baby teeth have been lost and the permanent teeth are fully in place. However, orthodontic treatment is effective at any age. Adults make up a significant proportion of orthodontic patients, and the biological process of tooth movement is the same regardless of age — treatment timelines may be slightly longer in adults, but the outcomes are comparable.

Who Is Orthodontic Treatment Suitable For?

Orthodontic treatment is suitable for most people with healthy teeth and gums. Before treatment begins, any active decay or gum disease must be addressed — orthodontic appliances are not placed on teeth with untreated problems, as this would accelerate damage.

Treatment is appropriate for patients who:

• Have crowded, overlapping, or widely spaced teeth
• Have a bite problem such as an overbite, underbite, open bite, or crossbite
• Have jaw misalignment affecting chewing, speech, or facial balance
• Are missing teeth and need space created or maintained for implants or bridges
• Have completed prior dental treatment and are ready to begin orthodontic correction

It may not be immediately suitable for patients with advanced untreated gum disease, significant bone loss, or active infections. In cases involving severe jaw discrepancies, a combination of orthodontics and jaw surgery may be required. Your orthodontist will assess your full dental picture before recommending a treatment approach.

Orthodontic Tooth Extraction: When Is It Needed?

In some cases, the jaw does not have sufficient space to accommodate all the teeth in proper alignment. When crowding is severe and cannot be resolved by expanding the arch, selective extraction of one or more teeth may be necessary before or during orthodontic treatment.

Extraction is not a routine part of every orthodontic plan — it is reserved for situations where the teeth genuinely cannot be aligned without creating space. Your orthodontist will explain whether extraction is part of your plan and why, before any decision is made.

How to Choose an Orthodontist

Because orthodontic treatment is a long-term process — often spanning one to two years or more — the relationship with your orthodontist matters. Look for a specialist with recognised orthodontic qualifications, experience with the type of appliance or case you require, and a clinic with modern imaging and planning technology.

At your initial consultation, pay attention to how thoroughly the orthodontist assesses your case and how clearly they explain the proposed treatment plan, alternatives, and expected timeline. A good orthodontist will take the time to answer your questions and set realistic expectations before treatment begins.
