Braces and aligners are devices designed for straightening crowded or crooked teeth, as well as a misaligned jaw (malocclusion). Orthodontic treatments move your teeth by applying pressure on them for a long period of time. Eventually, your jaw gradually adapts and conforms to the applied force. Contrary to common notion, the teeth are not connected directly to the jawbone. There is a membrane underneath our gums surrounded by bones that connects the teeth to the jaw. The membrane is flexible and responsive to pressure, making the teeth move when orthodontic treatments are applied.
