IMO, you may have both.
This is just my perspective:
Your teeth problems regardless of what the label you give your illness,always comes from acidosis.
This means that whatever the illness is that you have, it has set up your system to lean towards being acidic.
If your teeth problems were only on the outside of your teeth, I would say to treat your mouth topically…but acidosis means you can take all kinds of topical meds for skin and teeth, but they are being damaged first from the inside (as skin is also the way we eliminate).
I would work towards alkalizing your diet (not your tummy acid, thats all together different).
Then I would get your lymph moving so that you eliminate/move that acid.
I was told I was too acidic by my naturopath and I had a hard time with it.
Im mostly raw vegan prior to this candida problem, so I refused to believe I could be acidic on such an alkalizing diet.
Turns out I wasnt moving my lymph, so all my natural cellular debris, which is naturally acidic, couldnt be eliminated, and the diet couldnt neutralize it.
So, whatever it is you have, to simplify it all, you still have to get all your systems functioning well so that the body can heal itself.
I have to keep reminding myself, the body is brilliant. Its capable of healing itself. We just got to stop doing whatever it is we are doing that keeps it from doing its job 🙂
