hi i would like to ask some questions.
i had white tongue, is it normal?
is it because of hot weather? i never mentioned my tongue color before, until i read some HIV articles.
so worried about it. i took HIV test and the result was negative.
is it because of heat? 上火?
or because of lack of hygiene of my mouth?
some articles said because of dehydration, stress, anxiety. i had anxiety about HIV, since i received strangers SMS. thats the reason why i took the HIV test too.
thanks for your time and please reply me as soon as possible.
