Invisalign Palatal Expander System

What is Invisalign® First?

Invisalign® First is a treatment designed just for little smiles – it’s a phase 1 treatment option that provides effective results. And even better, it’s designed to treat a host of issues in growing smiles – ranging from the simple to the complex. Whether your child has spacing issues, crowding or narrow arches, Invisalign® First can help.

What are the benefits to Invisalign® First?

Invisalign® First provides a comfortable and easy way for your child to correct their orthodontic issues. The aligners fit snugly over their teeth and gently work to correct whatever issues are present in your child’s developing mouth. Your child doesn’t have to worry about trying to brush and floss around brackets and between wires because the aligners are removable. That means oral care is a snap – just remove the Invisalign aligners and brush and floss as always. And because there are no brackets or wires, Invisalign® provides a more comfortable experience for our youngest patients.

When is Invisalign First used?

Invisalign First is used as a Phase 1 treatment. This typically occurs in our youngest patients between the ages of six and 10. The goal of this treatment is to help intervene to correct developing issues in order to make room for all of the permanent teeth. Invisalign First can:

  • Prevent existing bite issues from worsening
  • Straighten teeth
  • Improve the smile’s appearance
  • Correct issues caused by habits such as thumbsucking or tongue thrusting
  • Make the next phase of treatment more efficient and effective.

Invisalign First can treat a host of orthodontic issues in developing mouths and is designed specifically for our youngest patient’s smiles. If you’re wondering whether Invisalign First may be the right solution for your child, call Hawaiian Smiles Orthodontics today.

Palate Expansion with Invisalign

Some children have a narrow upper jaw, which can lead to crowding, crossbites, or breathing concerns. A palatal expander used with Invisalign First gently widens the upper arch while staying comfortable, clear, and removable. Unlike traditional expanders with metal hardware and daily screw-turning, Invisalign expansion is digitally guided, providing a cleaner, more precise, and more natural-feeling process. Kids can brush normally, eat comfortably, and feel confident during treatment — without the bulk and visible metal of older expanders.

How It Works

  • A digital scan is used to create a series of custom expanders.
  • Each stage gradually widens the upper arch.
  • Small, tooth-colored attachments help keep the expander secure.
  • After expansion, a short holding phase maintains the new width.

Wear & Care

  • Full-time wear is important (remove only to brush and floss).
  • Safe to eat with the expander in — just avoid sticky or chewy foods.
  • Clean with a soft toothbrush and cool water (no hot water).
  • Temporary speech changes or light pressure are normal at first.

What to Expect

  • Expansion is gradual and generally comfortable.
  • Speech may sound different for a few days as the tongue adjusts to the appliance.
  • A small space between the front teeth may appear – this is expected and temporary.
  • Most children adapt in just a few days.

If your child has crowding or bite concerns, we’ll let you know whether Invisalign First plus palate expansion is a good fit during their evaluation.
