Hello, I am 15 years old and I'm struggling with bad breath. I have a dentist but he is a family friend and I am to embaressed and nervous to ask him for help. I have tried ProFresh and it kills most bacteria in my mouth and tongue but there is a white film over the back of my tongue. I have also tried the OraBrush and that has not worked for me either. I am in search for a cure, please get back to me please, thank you.
