How do braces work?
In: Engineering
The metal wire held in by the brackets can be tightened and shaped in order to put long term pressure on the teeth that are out of shape. When teeth have had pressure on them for about 10 hours, the bone that is holding the tooth in place sends out an enzyme to break down the exact area of bone where the pressure is being placed onto the bone, and makes new bone at the opposite side where there is now a tiny gap due to the tooth moving. Over time the metal wire can be tightened by a special brace dentist who decides what teeth need to be moved and to where, and the process is repeated until the patient has the desired result.
