Time-indicating syringe mixing systems for mixing, storing, and dispensing a two-part dental composition that becomes less stable upon mixing including a first plunger comprising an elongate stem and a plug at a distal end of the elongate stem, a hollow first chamber configured to contain a first component, a hollow second chamber configured to contain a second component, and means for indicating a recorded date when a first component initially contained within the hollow first chamber is mixed with a second component initially contained within the hollow second chamber. The inventive syringe mixing systems may be configured as syringe-in-syringe systems and/or syringe-to-syringe systems.
