What type of material is commonly used to cement crowns and bridges?

Dental cement is the most commonly used material for cementing crowns and bridges due to its specific properties that make it ideal for this purpose. Dental cements are formulated to provide a strong bond between the restoration and the tooth structure, ensuring durability and longevity of the restoration. They can also accommodate the various materials used in crowns and bridges, such as porcelain or metal, and they often have properties that allow for some flexibility to absorb forces during chewing, which can help prevent the cement from failing over time.

Additionally, dental cements can possess antibacterial properties, contribute to the health of the surrounding tissue, and in some cases, they may even provide fluoride release, which can be beneficial for tooth health. These characteristics make dental cement particularly suitable for both temporary and permanent restorations in dentistry.
