Sometimes yes. If the tooth structure underneath is sound, and the cement has simply separated from the tooth, the crown can be cleaned and cemented back on. Sometimes, however, the crown breaks at the gum line or with some tooth structure in it. In these cases, an alternate treatment may be necessary.  This could be a new crown if there is enough tooth structure or an extraction . If this is the case, Dr. Parsa will discuss possibilities such a crown, dental implant, a bridge, or partial denture.
