Found myself liking to breath in through my mouth until i feel a dryness where my tongue sticks to the roof of my mouth. like the air taste. help.

Decay prone: I can't explain why you like to dry your mouth, but i can tell you that a dry mouth makes it easier to get decay. Your saliva is your first defense against decay. It neutralizes the decay causing acids.

Habit or blockage?: Is yor mouth breathing habit or due to an obstruction such as a sinus problem? This is worth knowing because mouth breathing can increase dental decay and other problems.
