Expanders & early treatment
Sometimes the best time to act is while your child is still growing. Appliances such as palatal expanders can guide jaw development and create room for adult teeth — often making any later treatment simpler.
Guiding growth at the right time
For children aged 7 to 12, our Growth Guidance Program keeps a close, friendly eye on how your child's smile and jaw are developing — so we can act at exactly the right moment, not too early and not too late.
If treatment is needed later, that might mean braces or Invisalign® — but acting early can make that next stage shorter and simpler.
What is a palatal expander?
A palatal expander gently widens the upper jaw by easing apart the natural growth join in the roof of the mouth. As it widens, new bone fills the space, creating room for adult teeth to come through in better positions.
It's most effective while children are still growing, and is often used to correct a crossbite, relieve crowding, or make space for teeth that don't have room — and it can sometimes help with mouth breathing too.
What to expect with an expander
The expander is adjusted a little each day with a small key — something we'll show you exactly how to do. Your child may feel mild pressure for the first few days, notice a slight change to their speech, or have a little more saliva than usual. Most children adapt within about a week.
Soft foods help in the early days, and a small gap may appear between the front teeth — that's a normal, healthy sign the expander is working, and it usually closes on its own.
