Theory? What else other than bacteria would rot and eat away at the enamel and pulp of a tooth? If you can’t get to the dentist or can’t afford the dentist and have a cavity, put some raw garlic on it, that kills the bacteria and helps with the pain, well it does after you get over the burn of the raw garlic itself. Cloves or clove oil will do the same but not quite such a burn. You’ll eventually have to get a filling, but doing this will minimize the pain and infection for the duration until you do.
Does fluoride kill bacteria? And yes re garlic...my husband thought he was going to have to have a root canal...used garlic...seems to have cured his problem...for n I w...I’ll tell him about clove oil...the garlic blistered his gums.
