I have what I call canker sores from time to time. I read that vitamin B1 was good for this, so each time I start having them again, I take 100mg of B1 for a while and it works.

As far as the TMJ, that is an indicator of a magnesium deficiency. The muscles in your jaw are contracting. Mercury interfers with magnesium, so we all need to take extra. My TMJ went completely away several years ago.
