I'm just wondering what are some causes of bad breath are. My breath does not have the most pleasant smell. Every time I talk the smell comes out. The bad breath is at its worst in the morning. Also there is this white sticky thing on my tongue at the back. I'm not sure if that is what is causing it. I have tried using a tongue cleaner (it is on the back of my toothbrush) but it barely gets off. Its pretty much always there so I need to use my fingernail to scrape it off. Is there such thing as a tongue scraper or something? If so where can I buy it? Could you give me some names of shops and their suburbs? Also how are you supposed to floss the your very back teeth? That job for me is pretty much impossible. I can barely even reach the back. Could you send me a video showing me how to floss all my teeth or can you explain to me how to do it?
