Temporary crown

A temporary crown (white) on a tooth after Endodontic therapy

A temporary crown (provisional crown, interim crown) is a temporary (short-term) crown used in dentistry. Like other interim restorations, it serves until a final (definitive) restoration can be inserted. Usually the temporary crown is constructed from a chemical-cure composite, although alternative systems using aluminium crown forms are occasionally used.[1] Temporary crowns function to protect the tooth, prevent teeth shifting, provide cosmetics, shape the gum tissue properly, and prevent sensitivity.[2]

A temporary crown will usually be cemented in place with a soft temporary dental cement.[3] This allows for easy removal when fitting the permanent crown.

If a temporary crown becomes decemented, it is important that a dentist examine the patient as overeruption of the opposing teeth may prevent accurate fitting of the final crown.[4] If a dentist cannot be seen in a timely manner, the temporary crown may be recemented by applying temporary cement to the temporary crown.
