Braces Dissolve Parts Of Your Jawbone
Though it sounds torturous, the process of breaking down and rebuilding bone in the body is a natural one. In fact, it can make your bones stronger! When subjected to a steady force, like the one applied by braces, areas of bone are broken down by cells called osteoclasts. When the force is removed, cells called osteoblasts arrive to rebuild the bone. The dissolving process takes around 72 hours to begin, whereas the rebuilding takes around 90 days. However, for permanent and fortified results, the affected area should be stabilized for around 10 months.
