As children grow, their jaws and teeth grow. Sometimes, the upper and lower jaws do not grow in harmony. This can lead to issues such as protruding teeth, an underbite, or an imbalanced facial appearance.
What is growth modification?
Growth modification is an early orthodontic procedure that guides jaw growth while your child is growing. It focuses on guiding jaw growth so that the upper and lower jaw develop in a more balanced way. As child is growing, orthodontists can work with natural growth to reduce the need for more complex treatment later in life.
When should parents consider it?
Most children benefit from an orthodontic check-up by around 7 years of age. Growth modification usually starts between 8 and 14 years, depending on child growth rate. An early check-up helps the orthodontist decide if treatment is needed and when is the best time to begin.
What problems can it help with?
Growth modification can help with:
- Controlling excessive jaw growth
- Encouraging growth of a smaller or backward-positioned jaw
- Widening a narrow upper jaw
- Correcting abnormal jaw positions
- Improving facial balance
- Correcting harmful oral habits
Treating these concerns early can prevent them from becoming more complicated as your child grows. It can also improve jaw balance, child’s facial profile, and boost confidence.
How does the treatment work?
Growth modification uses special orthodontic appliances that gently guide jaw growth. These appliances may be fixed in the mouth or removable, depending on your child’s needs.
Common appliances include:
Devices that help bring the lower jaw forward (e.g., Twin Block, Herbst appliance)
Devices that help bring the upper jaw forward (e.g., Facemask)
Devices that control upper jaw growth (e.g., Headgear)
Devices that widen a narrow upper jaw (e.g., HYRAX)
- Devices that improve jaw and teeth position (e.g., Bite plates or Bite planes)
The orthodontist will the child regularly to monitor growth and adjust the appliance as needed.
Will the child be in pain during treatment period?
Most children experience only mild pressure or discomfort when the appliance is first fitted or adjusted. This usually settles within a few days and can be managed with soft foods and simple pain relief if needed.
Final note for parents
Growth modification works best when started at the right stage of growth. It supports your child’s natural jaw development and helps build a healthy, confident smile.
If you are concerned about your child’s bite, jaw position, or improper alignment of teeth, an early visit to an orthodontist can be a very helpful first step.
