Dental adhesives are specialized materials used in dentistry to bond various components, such as crowns, bridges, and fillings, to teeth. They create a strong connection between the dental material and the tooth structure, ensuring durability and longevity of dental restorations. These adhesives come in different forms, including resin-based, glass ionomer, and composite adhesives, each with unique properties suited for specific applications. Proper use of dental adhesives is crucial for successful dental procedures, as they help prevent issues like decay and leakage around restorations.
