My tooth got brown under the crown (Photo)

Question

Today I went to my dentist to replace crown that he did a month ago. There was too much of metal margain sticking out so he’s replacing it with one that has porcelain margain at the front.Today when I had my old own crown taken out I realized that my tooth (thats still alive) has darkened out significantly. Does the discoloration means that there’s something wrong with a tooth?Should I be worried (Sorry for grammar mistakes English is my 4th language).

Hi:The color of your tooth appears to be ok.  This is a normal color of the dentin under the enamel of the tooth.‘Best,Dr. Maddahi

Amber Garcia, DDS · Answer

That is a normal color for a tooth after the enamel has been removed. The enamel of the tooth is whiter in color. The dentin under the enamel is darker naturally.

Andy Shieh, DMD · Answer

Tooth discoloration is very common under crowns. Often the discoloration comes from old silver filling staining. Your tooth most likely had a large silver filling on it at one point and that’s why the color of tooth is darker. Another potential is that the old crown’s metal stained the tooth but this theory is much less likely since the old crown was only on the tooth for short period of time. Other potential reasons for tooth staining includes decay and tooth dying but I don’t believe either of these two are the reasons why your tooth is dark.
