Invisalign First: clear aligners designed for growing mouths
10 August 2026 · 4 min read
Invisalign First is made for children with a mix of baby and permanent teeth — including gentle arch expansion.

Built for mixed dentition
Invisalign First uses special attachment and eruption-compensation features so aligners fit around baby teeth and leave room for permanent teeth that are still coming through.
Expansion without a metal appliance
For many mild to moderate narrow arches, aligners can widen the dental arch gradually and create space, which children often find far more comfortable than a fixed expander.
What makes it succeed
Wear time is everything. We set a simple routine — in after breakfast, out for meals, back in immediately — and track progress at short review visits so small deviations are corrected early.
