A dispensing device for a dental substance is provided which has an outlet for the dental substance, and a valve for opening and closing the outlet. The device is switchable between a storage mode and an operative mode. In the storage mode a cannula is locked in the device and the valve opens the outlet, and in the storage mode the cannula can be released from the device and the valve closes the outlet. The device may facilitate handling and may be relatively inexpensive. |
