can occur for a few days after extraction of the wisdom teeth because the extraction can be a bit different from the other teeth. When the drainage accumulates, it subsequently is invaded by the bacteria giving rise to the horrible smell. This is not infection and usually does not require antibiotics. The cavity that is present would decrease in size with packing so also the drainage. However, there can be quite a bit of pain and swelling till about 2 weeks after extraction and especially following packing but this would also subsequently come down if there is no infection.
