The sensitivity has subsided even more today, so that I don't feel much of anything when I drink liquids now.
I'm thinking that it must have to do with the combination of flushing and OP at the same time. I know that the megadose of magnesium can cause some mineral shifts especially with calcium(often reducing calcium levels), and I would guess that since teeth absorb calcium from saliva that the oil MAY be capturing that calcium during OP. So, perhaps the calcium/magnesium shift that any other time might go unnoticed is prolonged a bit, in term of teeth, because of the removal of some of the calcium by the oil. If someone knows this line of thinking to be totally off-base, please let me know, and clarify, thanks.
I have read that the teeth are in a constant state of losing and reincorporating calcium, magnesium, and other minerals into the matrix from the saliva and with the help of xylitol. I can only guess that this system was affected by the flush/OP combination. I supplemented calcium(no magnesium) last night and this morning, and believe that may be helping to get the ratios balanced again.
I'm just glad the sensation is passing, that had me a little worried.
