First of all, bad breath has nothing to do with heredity. Generally speaking, bad breath will not be passed on to children. There are many reasons for bad breath. Maybe our oral hygiene is not very good, maybe we have decayed teeth, or maybe our wisdom teeth are inflamed, which leads to bad breath. Of course, it may also be related to chronic diseases of the digestive system, or it may be like getting angry. Some minor symptoms can be solved perfectly as long as we check them out and prescribe the right medicine. If your mouth smells bad, you should first go to the stomatological hospital to check your mouth to see if the bacteria in your mouth exceed the standard, or if there are any other lesions. Also check your teeth to see if there are many calculus on them. Or there is tooth decay, or inflammation of wisdom teeth, which causes our bad breath. If it is an oral problem, we only need to fill and wash our teeth, or rinse our mouth with mouthwash frequently, and then we can solve our bad breath problem. If there is nothing wrong with the mouth, then we should check whether there is gastroenteritis, because our digestive organs are connected with our mouth. If our stomach or intestines are not good, it will lead to a certain degree of bad breath. We can go to the hospital for a helicobacter pylori test to see if there is chronic gastritis. If there is, active treatment and conditioning can also solve our bad breath problem perfectly. Of course, we should also pay attention to the normal diet health, and don't just pay attention to the diet. If you are stressed for a while, getting angry can also lead to bad breath. As long as you relax and drink plenty of water, this symptom will disappear at will. In the process of treating bad breath, if we need to talk with people at close range, we can choose to use oral spray to temporarily relieve the symptoms, or we can eat some chewing gum and sugar to avoid feeling inferior because of bad breath and not being able to talk with close people, which will affect our work, study and feelings.
