Hello sir, I m suffering from bad breath, right after one hour post brushing my breath starts stinking. I brush in morning and at night while going to bed. In evening, I massage my teeth with manjan. I clean my tongue daily twice which becomes white. I also do scaling once in six months. Mouthwash helps for 4-5 hours but I want to naturally maintain fresh breath. Dentists had done all types of fillings and always recommend mouth wash. So now after being so particular and hygienic, what else can I do? Which is the appropriate type of doctor I should visit? Please help.
