371 devices · GMDN 45232
Dental coating, tooth-desensitizing devices are applied to exposed dentin to relieve sensitivity caused by factors like temperature changes, pressure, or acid exposure. They work by creating a protective barrier within the microscopic tubules of the tooth, reducing nerve irritation and often incorporating fluoride or antimicrobial agents to further strengthen enamel and prevent decay.
These products are typically available over-the-counter (OTC) and designed for home use or in clinical settings, though they are single-use and not reusable after application. Regulation varies by jurisdiction, but they are generally classified as low-risk medical devices due to their minimal systemic interaction and intended temporary use.
