The invention relates to a dental impression composition and method of use thereof for taking impressions of the teeth amd gums and/or for the delivery of actives thereto; containing a color change indicator to signal when the temperature of the dental impression material is at the "warm impression" state, so that the impression composition is soft and malleable to conform to and engulf the teeth and gums. Further, the color indicator subsequently signals when the dental impression composition has cooled to a solid state and can be removed from the dentiture without deforming, so as to maintain an accurate impression. |
