How do braces work?
Braces are a dental solution which straighten teeth by applying constant and consistent pressure over a period of time to shift the position of the teeth and move the teeth in a specific direction. This is achieved by the arch-wire putting pressure on the brackets which transmit the force to the teeth. Sometimes, springs or rubber bands are employed by the orthodontist to exert more force.
The bio-mechanical process of teeth moving under pressure is known as bone remodelling. When pressure is exerted on teeth, the periodontal membrane is extended on one side and compressed on the other. This loosens the tooth and the bone changes shape and grows to anchor the tooth in the new position.
