Foul taste in mouth after tooth pulled?

Putrefaction... The contents of a recent tooth extraction socket is the "perfect storm" for bad smell: warmth, moisture, bacteria, and abundant fermentable organic debris, blood clot, and exuding serous exudate. Every recent extraction smells and tastes bad until the natural healing process allows the wound to close over, bringing resolution to the problem.
