Braces hurt so much because they are dissolving your jawbone

Misaligned teeth can put you at risk for tooth decay, gum disease, and even tooth loss. Braces shift teeth by applying pressure, which constricts blood flow to the surrounding tissue that holds those teeth in place. That in turn causes special immune cells called osteoclasts to rush in and dissolve part of the jawbone, creating a space for the tooth to slide over and relieve the pressure.
