There are instances when the upper and lower jaws do not align properly affecting bite and nutrition. The problem is more associated as a misalignment with one part of the jaw protruding over the other. There are products such as coil springs which forces or align the jaws together in conjunction with braces to fix the teeth alignment. This is usually done at the same time to minimize the discomfort associated with braces which exists in the first phases. The braces are first fitted onto a mold that is taken of the teeth and placed using semi-permanent laser activated dental glue which has the consistency of ceramic as it is cures (usually using a laser). The braces are then fitted and adjusted as needed to achieve the desired result. The initial phases are painful due to the pushing/pulling on the tooth and the underlying structures of the jaw as the teeth are re-aligned. Treatment can take a few years to achieve the proper alignment for it gives time for the teeth and other tissue to heal.
