What is the purpose of using elastics in orthodontic treatment?

The primary purpose of using elastics in orthodontic treatment is to apply specific directional forces to the teeth. These elastic bands help in adjusting the positioning of teeth by creating tension that guides them into their desired alignment gradually. This is essential in ensuring that the teeth move into the correct positions within the jaw, allowing for improved occlusion and overall alignment.

Elastics can be customized in their placement and degree of force, enabling orthodontists to target particular issues such as overbites, underbites, or midline discrepancies. This targeted approach allows for more precise movements than what could be achieved with braces alone, leading to effective treatment outcomes.

Other options do not accurately reflect the primary use of elastics in orthodontics. For example, while chewing ability is important for overall dental function, elastics do not directly enhance this ability. Similarly, although colors might be an aesthetic preference for braces, this is not a functional purpose of elastics. Lastly, preventing decay is essential in orthodontic care, but elastics do not serve this role; rather, good oral hygiene practices are what contribute to decay prevention during treatment.
