Most bad breath is caused by bacteria. Bacteria that produce bad breath can easily breed behind the tongue, in the nasal cavity, between teeth and gums. When bacteria multiply in the mouth, they will produce putrescine and isovaleric acid similar to foot odor contained in carrion, thus forming an unpleasant breath. In addition, if the child's breath becomes bad, it may also be caused by sinus obstruction.
In addition, bad breath may also be caused by the brain. About 1/4 people who go to the dentist to solve the problem of bad breath actually don't really have bad breath, but they are too scared to think that they have bad breath. The best way to know your tone evaluation is to ask a trusted family member or a friend who won't be embarrassed.
Provide the following good ways to eliminate bad breath. As long as you are diligent and continue to care about oral health, you won't let bad breath become an insulator between yourself and your popularity:
1. Brush your teeth and rinse your mouth regularly every day, and remember to clean your tongue.
2, mouthwash can also help remove tartar, but if it contains alcohol, it will dry the mouth and make the breath worse.
3. Drink plenty of water to promote the flow of oral bacteria.
