Can drinking to much alcohol cuase thrush like symptoms in your mouth? which looks as though you were a bit dehydrated ?

Yes: Yes, as alcohol can change the normal flora in the mouth, leading to cases of thrush.

YES: Any condition that changes the natural balance of the microbial ecosystem of the mouth can potentially be the reason for an oral thrush infection. Poor oral hygiene, heavy smoking, excessive alcohol consumption, stress and certain medications that change the chemical balance of the mouth may have the same effect.( causing the fungus candida to grow out of control, causing infection).
