A viscous material dispenser, and dispenser system and kit, can include a dispenser without a dispensing tip and one or a plurality of separate dispensing tips that are removably attachable to the dispenser. The dispenser can be used with many different types of viscous material containing capsules and cartridges, such as those containing composites, dental cements, glass ionomers and the like. In embodiments, the dispenser can incorporate an integral activator for multi-component composition cartridges, such as glass ionomer cartridges.
