What Is Dental Cement?

Dental cement is used to connect a fixed prosthesis, such as a crown or bridge, to the underlying tooth structure. It can also be used as a pulp-protecting agent, cavity-lining material or temporary filling. Most dental cements come as a powder which is mixed with water to form a viscous liquid. Modern cements, such as glass ionomer cement, also come in capsule form which is mixed in a special machine. Dental cements can be classified as either permanent or temporary. Permanent cement is used to permanently attach a prosthesis. Temporary dental cement is used between appointments mainly for evaluation purposes.
