Cryogenic spray, dental

Cryogenic dental sprays deliver a cold refrigerant to a tooth to assess its vitality by testing how the patient responds to the sensation. Clinicians use this non-invasive method to evaluate whether dental pulp is healthy, inflamed, or dead, aiding in diagnostic decisions like root canal treatment or extraction.

These devices are single-use, disposable sprays and are not regulated as medical devices in all jurisdictions. They are typically classified based on their refrigerant composition and intended use, with supply and availability varying by country—always check local regulations before use.
