Is it normal for the inside of a tooth extraction site to be yellowish in color?

Possible: Immediately after extraction, the extractions site may be yellow, gray or white...

Maybe: After the extraction the socket and the tissue goes through the process of healing and regeneration and might turn different colors. If however you feel a lot of pain and pus coming out of the socket , you should see your dentist. Make sure you swish wit warm salt water for the first couple of days after extraction.

Yes: White or yellow fuzziness in an extraction site is normal.

Yes: It is pretty normal during the healing process. I assume you aren't having any pain, so everything should be fine.

Tooth extraction: Yellowish tissue can be dead or infected tissue that is going to be released by the body during healing.
