3M Cavit Temporary Filling

3M Cavit is the original and most trusted temporary dental filling material, used by dental professionals worldwide for over five decades. Its unique zinc oxide-based formula expands on contact with moisture from saliva and dentinal fluid, creating a self-sealing marginal adaptation that prevents bacterial microleakage and protects the tooth and any placed medicament between appointments. Cavit requires no mixing — it is dispensed directly from the tube and condensed into the prepared cavity using a suitable instrument, making it one of the fastest and most technique-insensitive temporary materials available. The material achieves an adequate hardness to withstand normal biting forces, maintaining a reliable seal throughout the interim period. Cavit is ideal for sealing root canal access cavities between endodontic appointments, covering post-extraction sockets, and providing short-term cavity coverage following caries removal. It is easily removed at the subsequent appointment using standard instruments.
