I've had plaque psoriasis for 7 years, all over my body and scalp. 8 months ago, I began to experience SEVERE tongue sensitivity. Everything burned except milk and water (NO visual symptoms on the tongue). Last week, saw dentist and he said my tastebuds were GONE, that the surface of my tongue was smooth and glossy. He had no idea what to think. I forgot to remind him that I have psoriasis, so I'm getting in touch with him after Labor Day. What I have read so far on the internet is that normally tastebuds, like your skin, regenerate every 28 days. With psoriasis of the tongue, the turnover can be as little as 3-7 days. This would explain why my tongue sensitivity comes and goes (carbonated beverages are REALLY painful!). Is anyone else having these symptoms?
