Sugar/acids wouldn't be as problematic if salivary flow (associated with acetylcholine and histamine) was normal and enriched with minerals (calcium, iodide, etc) and vitamin K2 MK-4. That is, the actions of saliva should normalize mouth pH in ~1 hour.Thanks for point that out. It prompted me to do a little more research into the pH of our mouth. Apparently in a healthy person, the pH of the mouth is kept at 7.5 or higher due to our saliva, which contains calcium, phosphate, arginine, and bicarbonate.
Coca Cola has an acidity of 2.5, oj has an acidity of 3.5, and milks acidity is 6.5
Coca Cola is definitely the worst offender, and oj doesn’t seem like it’s too clean either. Only oj causes gum discomfort and really worsens the inflammation for me, so there might be something more to oj than just the acidity, and in any case, I’ve noticed that too much sucrose isn’t good for my general well being anyways. Not that it needs to be eliminated, but moderated.

So perhaps rinsing the mouth with sodium bicarbonate after meals, on top of eating lots of calcium, vitamin D, And k2 is important as well for maintaining oral health.
Sugars and grains can indirectly affect oral health by wasting minerals/nutrients and vitamin C. In order to neutralize serum pH as blood sugar spikes, for example, the body enters a degenerative state to get calcium from bone. Cavities eventually occur if wasted nutrients aren't replenished or the body is consistently in a catabolic state, as teeth are broken down more than remineralized.
