Crowding happens when there isn't enough room in the jaw for every tooth, so teeth overlap, twist or sit out of line. Beyond appearance, crowded teeth trap plaque in places a brush can't reach, which raises the risk of decay and gum disease.

1How we create space
Mild to moderate crowding is usually resolved by gently expanding the arch and, where needed, creating fractions of a millimetre of space between teeth — a painless procedure called interproximal reduction.
Severe crowding occasionally still needs an extraction to create room. We'll always tell you honestly if that's the case, and show you the digital plan either way.
2Treatment with Invisalign
A digital scan produces a treatment simulation showing how your teeth will move week by week and what the end result looks like before you commit.
Aligners are changed roughly weekly and worn 20–22 hours a day. Most crowding cases finish within six to eighteen months, followed by retainers to hold the result.
