A dental device for shaping matrix bands. The device has a first arm pivotally connected to a second arm. A male head component having a curved, convex inner sidewall with a flattened surface centrally disposed thereon is connected to a bar portion of the first arm. A female head component having a curved, concave inner sidewall with a flattened surface centrally disposed thereon is connected to a bar portion of the second arm. When a handle portion of the first arm is pivoted towards a handle portion of the second arm, the first bar portion pivots toward the second bar portion. The male head component mates with the female head component such that the inner sidewall of the male head component interfaces with the inner sidewall of the female head component, and the flattened surface of the male head component interfaces with the flattened surface of the female head component.
