My dentist gave me a permanent cement on my temporary crown. How long does permanent cement last? Should I see my dentist again?

When a dentist thinks the crown may not be held in well with temporary cement, he might use "permanent" cement.  Permanent cement is a term used for cements that are used in final restoration.  They are harder, more retentive, and dissolve less that "temporary" cement.  Temporary cement is more rubber, can be removed easier, and can dissolve faster. There are many "permanent" cements for various situations.  They can last a year with a temporary crown.  Did you know that crowns can be done in a single visit?  It's call CEREC.

Probably longer than the temporary crown. See your dentist when you are ready to do a permanent crown.
