Dental adhesive is a specialized material used in dentistry to bond various components, such as crowns, bridges, and fillings, to teeth. It helps create a strong connection between the dental restoration and the natural tooth structure, ensuring durability and longevity. These adhesives come in different forms, including resin-based and glass ionomer types, each suited for specific applications. The choice of adhesive depends on factors like the type of restoration, the location in the mouth, and the condition of the tooth. Proper use of dental adhesive is crucial for successful dental treatments.
