A device for dispensing a dental material comprises a container for containing the material and an outlet which is closed by a closure. A breakable seal is arranged between the closure and the container. The device further is operable between a storage position in which the outlet is closed and an operational position in which the outlet is open. An initial operation toward the operational position causes the seal to break, whereby the closure is captured in the device. The device may provide a relatively long shelf life for the material, and may facilitate preparation of the material for use.
