While I think brushing, flossing, mouthwash all play an important role. Nobody is teaching you how to breakdown the actual problem. Besides genetics if your hygiene is sufficient. The food and drinks you consume are to blame. Bacteria are influenced from your diet. Change what you consume and your bodily systems will adjust accordingly, that being said cause and effect should be noted. Changing one system will modify others good or bad. Tailor your intakes based on the symptoms your trying to mitigate by learning how those systems work individually and then cohesively together. The fastest way albeit quite inconvenient is to log every food, drink, and consumable item that goes into your mouth each day for X number of days and find trigger foods which cause your symptoms. Analyze and extrapolate the data. Refine through trial and error. Tailor your diet to suit.
Because if I choose squirrel everytime I’ll never get anything done.
