i have both dry lips and white film similar to urs. i think when the skin drys up and then gets wet with our saliva it turns into soft white film. i notice my saliva becomes sticky and the film builds up on my front teeth after i eat. i also notice i have hundreds of white dots inside my checks that are abnormal. i think those white dots inside my checks and mouth are a status of how bad our mucous membrane (inside lining) of our mouth and intestine. i think we all have the same problem, we just need to do more experiments to find a cure. anyone know what those white dots inside our checks could be?
