What Causes the Whole Tooth to Turn Black Under a Temporary Crown?

Question

I had a back tooth that was chipped and the filling was old so the Dr. recommended a crown. After all the prep work, a temp crown was put on and i returned 3 weeks later for the permenant one. when the Dentist took off the temp crown the whole tooth had turned black. He basically wiped it clean as best he could but the whole tooth was "stained". He has nott seen this before and searching for and answer.. as am I??? might anyone know what could cause this?

If the tooth turns black under your temporary crown, it is because of micro leakage, and the fit of the temporary crown is not perfect. Most often if you used peridex or chlorohexidine, also or stained foods and drinks, that also contributes to color of black under temporary crown.

Norman Huefner, DDS · Answer

Actually this is not uncommon.  Somehow your temporary crown loosened up a bit, probably from chewing on it, and this allowed a microscopic space for bacteria and fungi to set up residence under the temporary crown.

	When the dentist took of the temporary crown there might have been an annoying odor and the tooth would have appeared black.  It is often times known as "black scuz" to dentists (not a technical name).

	The black scuz and odor can easily be removed in about three seconds by bathing the tooth with regular old hydrogen peroxide solution.  No harm, no foul.  No permanent damage either.

You should return to the dentist to have the temporary checked as it is not sealed well.  Leaving the temp with the black stain could lead to a lot of sensitivity on that tooth once the final restoration is seated.  The black stain can be removed from the tooth with pumice and peroxide by the dentist

This is not so unusual. When the temporary crown leaks, it happens. Tooth can usually be returned to its original color by polishing with a mixyure of dental pumice and hydrogen peroxide. Not to worry!

Carlo Biasucci, DDS · Answer

This is usually due to leakage of saliva under the crown - it can be cleaned with peroxide and a brush and is of little consequence as long as the tooth isn't sensitive.
