Dental cement is a specialized material used in dentistry to bond various components, such as crowns, bridges, and orthodontic appliances, to teeth. It provides a strong and durable connection, ensuring that dental restorations remain securely in place. There are different types of dental cements, including glass ionomer, resin-modified glass ionomer, and zinc phosphate, each with unique properties suited for specific applications. These cements can also help seal gaps, preventing bacteria from entering and causing decay, thus contributing to overall oral health.
