The most common cause of bad breath is poor oral hygiene. Perhaps you forget to brush your teeth or are not doing it thoroughly enough. You can also chew mint gum after each meal, but no more than 10 minutes. If this does not help, you should see your doctor, as bad breath can be a symptom of a number of serious medical conditions.
Well, the reason may be not only in improper oral hygiene, but also in the food eaten! Some foods make the situation worse. For example ice cream! I myself did not know about it, but it turns out because of him it smells in the mouth! Look on the Internet for a list of foods that smell out of your mouth
Does this change with age? Guys, I ask you without banal vulgarities, you know what about.
