Dental cement

Dental cement fills the tiny gap between a restoration and your tooth. It holds the piece in place and seals the edge against germs and saliva. Several kinds exist, such as glass ionomer, resin, and zinc-based cements. A review in the NIH library says cementation aims to bond the prosthetic restoration to the prepared enamel or enamel and dentine. A dentist may use a weaker cement for a temporary crown so it can be removed later. The choice depends on the material, such as zirconia or porcelain, and on how much tooth is left. If a crown feels loose, call the office. See glass ionomer and our dental crown page.
