Like yourself (and the other posters) I'm prone to tooth pain that's not explained by "conventional" science.
I've linked it to the fact that I have hyperactive nerves throughout my body.
In fact, computer monitor flurescence somehow triggers my nerves body-wide, causing many pains, including eye pain, tooth pain, muscle aches/weakness, headache, speedy metabolism.
Other nerve triggers:
Acids, menthol (found in most tooth-care products), cold, heat, sugar
(YET NOTE THAT YOU NEED TO BE AWARE OF THIS TIGHTROPE, BECAUSE:
CONVERSELY:
sweet side-dishes/desserts & warm drinks (such as mullein-mallow/dandelion/cherryberry tea) ought to be accompanied with healthy meals in order to avoid constipation
Some stuff which helps to relax nerves:
GABA, Neurontin, rinsing mouth w/salt water
berries, black-cherry, peach-yogurt, celery, mullein, mallow, hops, licorice, lysine, bitters, greens, oils, rice...
