Eighteen months after the patient stopped thumb sucking most of the changes to the positions of the teeth that had been caused by the thumb sucking have corrected.
The upper teeth are now in a reasonable vertical position.
The upper posterior teeth have moved laterally so there is no crossbite tendency now.
While this improvement without active management can occur, it is unusual.
The younger habits can be ceased the more likely the improvement will happen without orthodontic intervention.
This example goes to show that at any age it is worth giving nature her chance to improve the positions of teeth.
