Health Benefits of Orthodontic Treatment

Health Benefits of Orthodontic Treatment

27th May 2026

Orthodontic treatment is often associated with improving the appearance of a smile. However, orthodontic treatment can also provide functional and dental health benefits in certain situations.

In the UK, orthodontic treatment need is commonly assessed using the Index of Orthodontic Treatment Need (IOTN). This clinical index helps determine whether orthodontic treatment may provide functional or dental health benefits for a patient.

What is the Index of Orthodontic Treatment Need?

The Index of Orthodontic Treatment Need (IOTN) is widely used by orthodontists to assess the severity of orthodontic problems and the potential benefits of treatment.

The index considers factors such as:

• Severe crowding of teeth
• Large overjets
• Crossbites
• Open bites
• Impacted teeth

Patients with higher IOTN scores are more likely to benefit from orthodontic treatment from a functional or dental health perspective.

Improving bite function

One goal of orthodontic treatment is to improve how the upper and lower teeth fit together. When the bite is not well balanced, certain teeth may experience greater forces during chewing.

Orthodontic treatment can help improve the alignment of the teeth and distribute biting forces more evenly.

Reducing the risk of dental trauma

Large overjets, where the upper front teeth protrude significantly, may increase the risk of trauma to the front teeth. In some cases orthodontic treatment can help reduce this risk by improving the position of the front teeth.

Supporting oral hygiene

When teeth are significantly crowded it may sometimes be more difficult to clean effectively between them. Aligning the teeth can help improve access for brushing and flossing, which may support long-term dental maintenance.
