ve also experienced sporadic pain that radiated from the LL to LR each month like clockwork. I eventually got a root canal and crown on one side. Health wise, my
calcitonin levels are elevated but my TSH levels are normal. I take synthroid daily, brush, floss, rinse. Could there be a correlation between thyroid hormone levels and tooth decay. I admit to having extensive dental work, but I've never had this amount of deteriation over the past two years.
