I wouldn't imagine you could heal a cavity. It is a whole in the tooth where it decayed. I don't think you can grow back your tooth.
I know the body can slowly regrow enamel.
I actually got cavities for the first time after becoming vegan. I doubt it's correlated but they haven't healed or anything like that.
Thanks for your testimony. I agree.
I noticed too that healing of superficial cavities is easy (I had one just becoming brown and it is now almost the same color as my teeth) but it seems to be stabilized for the other ones.
Anyway, if healing is possible, it can only comes from the inside, so, from a healthy body and sufficient minerals.
A friend asked a dentist about this the other day and the dentist confirmed that yes, this can be done.
I think you are on the right track. I'll see if I can get more details from my friend's dentist.
Would be great ;-)
