This DIM sounds very promising actually. But it doesn’t sound like it needs to be ingested for staph mutans biofilm busting, rather be topically applied instead. And my problem with it is that apparently it tastes nasty. Might still give it a whirl though.
Xylitol tastes great and pretty much does she same thing: it doesn’t kill staph mutans but rather hacks away at its ability to stick to other staph cells and / or teeth — basically loosens staph biofilm so it can be either swallowed and killed in the stomach or removed with a toothbrush.
Also I don’t think it’s possible or at least not advisable even if it were possible to get rid of all mouth biofilm. I think you mean infected biofilm so that’s a meaningful distinction. Most bacteria in the mouth are commensal and even beneficial. Again both xylitol and DIM seem to selectively impair staph biofilm while leaving the other critters be, and in xylitol’s case at least, even feeding them.
Apparently saliva itself, provided we eat well, had decent digestion, and give it enough time to do its job, will remineralize teeth. It creates hydroxyapatite crystals of the right size and shape to be properly grafted on to tooth enamel. The problem, according to Ellie Phillips, is most people don’t let their mouths be long enough for this to happen — if you keep eating / snacking / drinking as the day is long, the saliva gets diluted and acidified and doesn’t get enough time to do its repair job. At night it’s also suboptimal in flow and composition for circadian rhythm related reasons. Our job is to practice “mouth rest” — intermittent fasting, including abstinence from water, throughout the day. And by intermittent she means 1-2 hours at a time at least going without putting anything in the mouth.
She also recommends small amounts of xylitol throughout the day (6-10g) to prevent plaque from taking hold and loosening any existing one.
Last but not least, a sequence of certain over the counter products every morning and night, and certain kinds of toothbrushes, used a certain way. I’m loth to get into details as I’m sure whoever reads my abridged take will miss important details but suffice it to say, there are compelling reasons why these products work when used in a sequence but might not work separately. I’ll just give one example: Listerine Original or Cool Mint have ingredients which are very beneficial for gums and also can kill staph and lessen its biofilm hopefully down to nothing when used regularly. HOWEVER the formulation is highly acidic which makes it really bad for teeth IF you leave it on as the last thing before going to bed. So it needs to be followed by something that will alkalize the mouth.
Anyway I highly recommend her YT materials. My teeth feel as if I’ve just had them cleaned at the dentist with zero plaque anywhere, and that’s a first. I used to think they were in good shape but now I realize that means zero plaque at all and zero cavities and it’s finally achievable.
