Overjet

This patient had crowding of the upper front teeth, which caused them to overlap. The upper teeth sat further forward than ideal, with a deep bite meaning the upper front teeth completely covered the lower front teeth on biting together. The back teeth also showed a mild imbalance, with the lower teeth positioned slightly behind the upper teeth.

Overjet is a common reason for patients asking us about Invisalign. If you'd like a more detailed look at how clear aligners correct these bite issues, our specialist orthodontists have written a longer clinical guide: Can Invisalign correct an overbite?

Underbite

A mild underbite, where the lower jaw sits slightly ahead of the upper jaw, together with a small chin asymmetry to the left. The front teeth met almost edge-to-edge. While the bite was well balanced on the left side, the lower teeth sat slightly further forward on the right.

Gap Teeth

Slightly protruding upper front teeth alongside a deep bite, where the upper front teeth completely overlapped the lower front teeth. The back teeth fitted together well, but this patient had recently had a lower front tooth extracted, which created spacing and alignment issues that treatment addressed.

Crooked Teeth

Moderate crowding of the lower front teeth made them appear crooked. The upper side front teeth were smaller than usual, and the lower teeth were slightly off-centre.

Crowded Teeth

Mild crowding of the upper teeth and moderate crowding of the lower teeth had caused some teeth to become crooked. This patient had previously had two upper teeth removed, which affected how the back teeth met together.

Crowding is one of the most common reasons patients come to see us. For more on what causes it and the full range of treatment options beyond Invisalign, see our guide to crowded teeth causes and treatment options.
