oral b...? can you link me to the one you're using so i know what to buy ^^ and I think you're right. When I pull back my bottom lip, theres a white line inside, and my entire tongue is white. I'm going to buy a scrapper and scrap ALL the white stuff off my tongue and use the mouth wash to clean my mouth. I think this is it. Let me know exactly what mouth wash you're using please and ty.
