Growth modification treatment helps guide jaw development in growing children to create a healthier, more balanced bite. By addressing skeletal issues early, this treatment supports proper facial growth and can reduce the need for complex orthodontic work later.
Growth modification treatment is an early orthodontic approach that guides the development of a child’s jaw bones during their active growing years. This is when permanent teeth begin to emerge and when early signs of jaw over- or under-development can first be detected. If skeletal imbalances are identified, growth modification allows us to gently correct or reduce their severity, potentially minimising the need for future braces or even jaw surgery.
Growth modification works by using orthodontic appliances that apply gentle, consistent pressure to the jaws, encouraging them to grow in a more balanced way. These appliances are custom-designed based on your child’s specific skeletal needs and are typically worn for several months to a few years, depending on the case. Rather than moving teeth alone, this treatment focuses on guiding the actual growth of the jawbones, helping to create the right conditions for the teeth to erupt in their proper place later on.
Growth modification can reposition the lower jaw forward to correct an excessive overbite, improving bite function and facial balance.
By encouraging proper jaw alignment, treatment can reduce or eliminate an underbite where the lower jaw protrudes too far forward.
Palatal expanders and similar appliances widen the upper jaw to correct crossbites, ensuring the teeth fit together correctly.
Growth modification can help close an open bite by guiding jaw growth and improving how the upper and lower teeth meet.
At i.Dental, we offer a range of growth modification appliances to help correct jaw imbalances and improve bite alignment during your child’s key developmental years.
Invisalign Mandibular Advancement is a modern solution for tweens and teens with Class II malocclusions caused by a lower jaw that sits too far back. It is built into the overall Invisalign treatment and uses clear aligners with integrated precision wings that gradually shift the lower jaw forward while straightening the teeth. This dual-function approach offers a more comfortable and aesthetic alternative to traditional functional appliances, with no need for separate hardware.
The Invisalign Palatal Expander is a modern, screw-free alternative to traditional metal expanders, designed specifically for growing children and early teens. It works by gradually widening the upper jaw using a series of doctor-prescribed expanders that are replaced in small increments.
After expansion is complete, your child will transition to palatal holders to stabilise the jaw, which are typically changed every 2 to 4 weeks.
The Herbst appliance is a fixed orthodontic device used primarily in children and teens to correct Class II malocclusions by encouraging forward growth of the lower jaw. It helps improve bite alignment in cases of overbite, overjet, or an underdeveloped lower jaw. Made of metal bands and connecting arms, the appliance stays in the mouth throughout the treatment period and is most effective during a child’s active growth phase.
Twin block appliances are removable bite blocks to help correct jaw alignment. They consist of one part for the upper teeth and another part for the lower that fit together when you bite, gently guiding the lower jaw forward into a better position.
These appliances are usually used in children and teens while their bones are still growing. Once the jaw is properly aligned, the twin blocks are removed and braces are often placed to straighten the teeth and complete the treatment.
Traditional palatal expanders are metal orthodontic devices used to widen the upper jaw, typically in children and teens whose jawbones are still developing. The device is attached to the upper molars using dental bands or bonding and features a small central screw.
By turning this screw regularly, gentle pressure is applied to gradually expand the upper arch. While the process may sound intimidating, it is usually well tolerated and can make a big difference in creating space for crowded teeth and improving bite alignment.
Orthodontic face masks are external devices used to correct underbites, most often in children and teens whose jawbones are still growing. They are typically paired with an expander or other orthodontic appliance and work by encouraging forward growth of the upper jaw.
The device rests on the forehead and chin, with elastics connecting it to hooks on the dental appliance inside the mouth. By wearing the face mask as instructed, gentle, consistent pressure is applied to gradually improve jaw alignment and bite. While it may look unusual at first, the process is generally well tolerated and can have a significant impact on facial balance and long-term dental health.
Growth modification helps achieve a more balanced facial structure. This early correction promotes harmony between the upper and lower jaws, improving both appearance and long-term dental health.
Proper jaw alignment makes it easier for children to bite, chew, and speak effectively. It can also contribute to better breathing, especially in cases where jaw discrepancies affect airway space.
Treating skeletal imbalances early can reduce or even eliminate the need for more invasive procedures like jaw surgery in the future. By intervening during the natural growth window, we can also often achieve results that are more stable.
Growth modification treatment is most effective when started during the early to mid-pubertal years, typically between ages 11 and 17, when the jaws are still actively developing. This timing allows us to harness the body’s natural growth to guide the jaws into better alignment. While treatment can occasionally be considered for adults, it is much less common, as their bones have largely stopped growing.
The cost of growth modification treatment in Singapore ranges from $500 – $8,000, depending on the complexity of the case and the specific treatment plan required.

Growth modification treatment helps correct jaw discrepancies and guides facial development during the growing years, setting the stage for better dental alignment. However, your child may still require braces later on to fine-tune tooth positioning. The benefit of early treatment is that it often simplifies future orthodontic work, reducing both the complexity and duration of braces.
During growth modification treatment, regular visits to the clinic are important to monitor your child’s progress and make any necessary adjustments. While the exact frequency may vary depending on the type of appliance used and the child’s individual needs, appointments are typically scheduled every 4 to 8 weeks. These visits ensure that the treatment is on track and adapted to your child’s growth patterns over time.
If your child is older and their jaw growth is nearly complete, growth modification may no longer be as effective, since this type of treatment relies on harnessing natural growth to correct skeletal discrepancies.
However, orthodontic options are still available. Braces or clear aligners can be used to align teeth, and in more severe cases involving jaw imbalance, a combined approach with orthodontics and orthognathic (jaw) surgery may be recommended.
It’s important to assess your child’s specific needs with a qualified dentist. i.Dental provides comprehensive orthodontic care for individuals at all stages of development, including tailored solutions for older children and teens.
Growth modification using functional appliances can be effective if the device is worn as prescribed and the patient is still in their active growth phase. However, effectiveness decreases if the appliance is not worn consistently or if the patient is older than around 14 years, when jaw growth slows down. In such cases, your dentist may recommend alternative approaches, such as:
Your dentist will guide you toward the best treatment option based on your child’s growth and specific needs.
Growth modification treatment is generally not painful, but some initial discomfort is normal, especially in the first few days after an appliance is fitted or adjusted. Children may feel pressure or mild soreness as their jaws and teeth begin to adapt, but this typically subsides as they get used to the appliance. Most find the discomfort manageable and temporary.
Children should ideally have their first orthodontic evaluation by around 7 years of age. This allows the dentist to assess jaw growth, dental alignment, and bite development early on. Evaluating your child at this stage helps identify any issues that may benefit from growth modification treatment while natural growth is still occurring.
