Two years after a having a pituitary tumor removed, I had 9 crowns replaced on my top row of teeth. Within 6 months of these replacements almost half of all of my teeth (on both top and bottom) have separated. I have been tested for acromegalia a couple of times, but always negative. My tongue has been swollen for 10+ years, and prior to these new crowns, I did have some minor teeth separation. Also around age 10 I did break my upper palate, and I am now 52. What else could possibly be causing this separation? Thank you.
