Does tooth extraction for braces at the age of 12 permanently alter your face’s development or is it reversible?

The space for the tongue and size of the airway are both affected adversely when Extraction (amputation) orthodontics are done.  It is far better to grow the bone to make room for the teeth that to extract and the downsize bone and airway.You can reverse the effects of extraction orthodontics with orthopedic growth appliances.My favorite system is the DNA Appliance by Vivos and Dr David Singh.  It reliably grows the bone orthoppedically and the airway orthopedically.

The removal of teeth generally does not change the underlying bone of your mouth and none of the bones that make up your face.   If you had an over bite or your teeth were protrusive, there may have been a change in how much your lips had to stretch to get them over your teeth but usually this is an improvement and can give your chin better definition.  The main cause of facial change is puberty, both your nose and chin grow and your face can significantly lengthen or shorten.  Changes due to orthodontic treatment are minimal compared to just normal pubertal growth.Your face looks like it does because of your parent genes.  To make it look like it did when you were 12 years old requires significant facial surgery.
