What is the purpose of orthodontic elastics?

Orthodontic elastics are an essential component in orthodontic treatment, specifically designed to apply consistent pressure on teeth and dental arches. Their primary function is to assist in the movement of teeth into desired positions by providing a gentle and continuous force. This pressure helps to align the teeth and jaws, making it crucial for achieving the overall goals of orthodontic therapy.

While creating space between teeth, supporting the arch wire, or improving gum health may be goals related to orthodontic treatment, they do not capture the primary function of elastics. Creating space between teeth is usually achieved through other means, such as tooth extraction or orthodontic appliances that specifically create gaps. Supporting the arch wire is the role of brackets and other fixed appliances, not elastics. Improving gum health is vital in dental care but is not directly associated with the purpose of orthodontic elastics, which focus on tooth movement. Hence, the mechanism of applying targeted pressure for tooth movement is the core reason elastics are used in orthodontics.
