A typical commercial mouthwash contains alcohol which can actually contribute to the formation of more venues for bacteria to breed and cause bad breath. This is because alcohol causes the mouth to dry, and bacteria breeds quickly on dry mouth; becoming more powerful to produce volatile sulfur compounds (VSCs) that produce bad breath. When a person does not brush his teeth and tongue as often as he should, floss at least once a day, and use an oral antiseptic, food particles that remain in the mouth and in between teeth will emit hydrogen sulfur vapors and bacteria. Hydrogen sulfur vapors produce a rotten-egg like odor which causes bad breath. If you use toothbrush, make sure that you brush your tongue at least 15 times. Using spoon as an alternative to clean your tongue can also give you a good result. 3. Use dental floss and mouthwash. Regular toothbrush cannot cover the entire surface area of your teeth so you need to use dental floss at least once a day and mouthwash.
