When placing a Tofflemire matrix band, which side should go around the gingiva?

The smaller side of the Tofflemire matrix band is designed to go around the gingiva. This is because the smaller side allows for a better fit and helps to avoid unnecessary trauma to the surrounding gum tissue. When placing the band, it is important to ensure that it properly contours to the tooth while also being positioned away from the gingival margin to protect the delicate gingival area during the placement and setting of dental materials, such as composites or amalgams. Proper placement of the matrix band is essential for achieving an optimal restoration, ensuring that the contact points and marginal adaptations are correct while also minimizing irritation to the soft tissues.
