Question:
vitamin deficences that cause the tongue to get cut.

I have cuts on my tongue and today I was told that it might be a vitamin deficience.    — insideout (posted on November 16, 2010)

It could be a lack of folic acid or B12. I would suggest some blood work if you haven't had one lately

Do some research on geographic tongue or tongue fissures. It can be a vitamin deficiency, so it's a good idea to get bloodwork done. It's not always a vitamin deficiency though. It's more common than you think. I had never heard of it when I was diagnosed with it nearly 15 years ago. At the time I had kidney issues and was on prednisone. I've always wandered if that's what caused it because all the blood tests show no vitamin defiencies for me then or now.

I actually had an allergic reaction to a strong antibiotic (Augmentin, to be precise), which caused a severe case of "glossitis"....my tongue started to feel burned or scalded, it seemed to lose all its taste buds, it became moderately swollen so it made talking a fairly interesting proposition....and the inside of my cheeks began to hurt. Even after I'd been off the medication for quite a while, it still stayed sore. This happened back in mid-August, and even though appearances have returned to normal, I am still not able to tolerate even the mildest of spicy foods. You could be suffering from an allergic reaction. But, a vitamin deficiency could also be the culprit - OR too much of a particular vitamin, like vitamin C.
