Which material is used in orthodontic separators to ensure they do not damage the teeth?

Orthodontic separators are designed to create space between teeth to facilitate the placement of orthodontic bands and appliances. The use of rubber in orthodontic separators is particularly beneficial because rubber is flexible yet resilient, allowing it to exert a gentle pressure on the teeth without causing any harm to the enamel or surrounding soft tissues. This flexibility helps to accommodate variations in tooth size and shape, ensuring that the separator can fit snugly while minimizing the risk of injury or discomfort.

Rubber's material properties also allow it to compress and adapt as needed, providing a cushioning effect that further protects the teeth. In contrast, more rigid materials such as metal could exert excessive force that might damage the enamel or lead to discomfort. While plastics and silicones are also commonly used in various dental applications, rubber specifically has the right balance of flexibility and durability to perform effectively as a separator without compromising the health of the teeth.
