Yes there is a connection between dental infections and parasites. The doc that knows this the best is Dr. Simon Yu in St. Louis
FYI-it doesn't matter if you have your wisdom teeth in or out you may still have an infection site there. Many people are waling around with a caviation right where the wisdom teeth were and that over years that lowers the immune system and opens the door to many issues-like lyme-ibs-fatigue-cancer-ect. The person is never cured until the jaw is fixed. Low level infection for years is very bad for health
