The main characteristic of a T band matrix is that it consists of a loop that holds the shape, which allows it to securely fit around the tooth during restorative procedures, particularly in pediatric dentistry. This design provides the necessary contour for proper cavity preparation and helps in shaping the restoration to match the natural anatomy of the tooth. The T band allows for easy placement and removal, making it practical for use on children's teeth where access may be more challenging.

This attribute distinguishes it from fixed appliances, which are more permanent and not designed for single-use applications like the T band. Although it can be applied without local anesthesia, that is not its defining characteristic. Moreover, it is not associated with whitening procedures, which involve different materials and techniques aimed at improving the shade of teeth rather than creating a restorative shape. Thus, the looped shape of the T band matrix plays a pivotal role in its function and utility in dental practice.
