Help. I'm so embarrassed but I'm at the end of my tether with this. The problem is me. I've had bad breath for as long as I can remember. I've been checked over by dentist, they couldn't find a reason for it. I've had my tonsils out. I have good oral hygiene, brush my teeth 2 sometimes 3 times a day. I floss, and use mouthwash. I use a tongue scraper. Within 10 minutes of brushing my teeth, its rotten again. Dentist said they can't smell it. Doctor said they can't smell anything. However I have had this for so long now and so many people have made comments, or whispers that I know for sure that I stink. I don't know what else to do. It's affecting every aspect of my life! I'm never ever without mints and chewing gum. I have some childhood/teenage fillings that I thought the smell could have been coming from but the dentist ruled that out. Does anyone have any ideas? I just want to be normal :(
