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

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?

Black Temporary

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

Tooth Turned Black Under a Temporary Crown

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!

Tooth turns black under temporary crown

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.

Black tooth under temp crown

There are billions of bacteria that live in the mouth and sometimes the conditions are just right that they will get under a temporary and turn it black. It is the bacteria that cause this and it can be cleaned off by brushing peroxide on the tooth. It doesn't do any damage, but if it is in front it can hinder the looks of the crown. Hope that helps!

Hey Mark,

I just wanted to let you know it is very unlikely the dentists will see your question in this section, as it is for community members to discuss the question. You are welcome to submit another Q&A if you would like.

I would also love it if you would post a review about your experience with your crown. It is a great way to get information and support from other community members.
