There is always a smell in the mouth, first check the periodontitis

I wake up every morning and there is always an unpleasant odor in my mouth. After brushing my teeth, the odor cannot be eliminated. This makes Mr. Zhang, 35, very troubled. Not long ago he walked into the clinic of the oral periodontal specialist, hoping to solve a problem that was plagued for a long time-oral odor.

Oral odor, the professional term is called "respiratory odor", its main cause is caused by local problems of the oral cavity, accounting for 80% to 90% of this disease. Some serious systemic systemic diseases: diabetes, kidney failure, esophageal reflux and other diseases of the digestive system can cause exhaled gas to smell, and chronic inflammation of organs near the mouth such as the nose and pharynx can also cause oral odor. Also, taking certain drugs can produce an unpleasant odor, but it is generally temporary, and can disappear after the drug is stopped.

For example, Mr. Zhang has no serious systemic disease, no medication, no rhinitis and pharyngitis, which can rule out systemic factors. The people around him reacted when they contacted Mr. Zhang, and the doctor had already smelled a bad odor when examining him, so mental factors could be ruled out. Then, it can be preliminarily judged that Mr. Zhang is "pathological breath odor". The problem should all come from the oral cavity.

There are two main causes of odor due to oral problems: periodontitis and thick tongue and tongue fur. In addition, deep caries, also known as insect teeth, or wisdom teeth that are often inflamed, are also causes of odor.

Poor oral hygiene, with a lot of calculus and plaque. There are many bacteria and calculus in the periodontal pocket, that is, the gums, which are the causes of odor. Smoking will aggravate inflammation and promote the growth of plaque, and the smell of tobacco itself is not good, it will also increase the odor of the mouth.

It is bacteria that cause inflammation, and it is these bacteria that catabolize the proteins of food residues in the mouth during the process of reproduction and survival, and produce unpleasant gas molecules. Among them, the most important are sulfides, including hydrogen sulfide, methyl mercaptan and dimethyl sulfide, of course, there are some fatty acids and amine compounds. These bacteria are best hidden in places that are not easy to clean. Professionally called "anaerobic bacteria", such as in periodontal pockets, tongue fur on the back of the tongue, deep caries holes, or in the gums around wisdom teeth, as long as it is not easy to clean Are easy to grow.


For Mr. Zhang, the first step is to treat periodontitis, quit smoking, wash teeth, deeply clean the calculus bacteria in the periodontal pocket, learn the correct brushing method, clean the interdental space with dental floss, and regularly review the treatment to maintain the effect. If you have caries, you need to fill your teeth. If the tongue coating is too thick, you can use a tongue scraper to clean the tongue coating.


Use the right brushing method

Brush your teeth twice a day, no less than 3 minutes each time.

Use a small head and soft hair health toothbrush. Brush the upper and lower teeth separately, focusing on cleaning the roots near the gums.
