Re: Tonsil stones/bad breath/tongue coating
Your white coating on tongue could be off post nasal drip that accumulates on your tongue when you sleep and thats probably what makes you have bad breath. If you scrap the white film on you tongue and has an odor , that's mostly where the odor is coming from and causing you to have bb.
Use an over-the-counter antihistamine or decongestant to reduce the mucus production in your nose and throat.
Also use a nasal irrigation kit , 2-3 times a day .
