You might be wondering, how the heck does braces work? All they are doing is just sticking two wires in my mouth for about two years and then out of nowhere, boom, straight teeth. Don't worry, they aren't using black magic or anything strange. All the orthodontists are using are laws physics, particularly, Newton's laws. In this case, when the wire is bent, the two tension forces create a vector force towards the back of the mouth. These continuous forces signal for the teeth to encourage the movement. But, if there is an interruption in the force, the teeth will not be signaled to move. Osteoclasts are released which signal for some bone to be removed in order for the teeth to move around. The constant force being applied is crucial for braces to work. So the science behind physics lies in the forces exerted by the wire!
