Find out the three major causes of bad breath and help you say goodbye to bad breath for many years:

First, bad breath.

COVID-19 made everyone wear masks, which made many people realize how smelly their mouths were. Most people have breath more or less. When the nose, mouth and exhaled gas are enclosed in a narrow space, any smell will be infinitely amplified. When the mask is taken off and the breath is diluted by air, the smell is naturally less scary. If your mouth smells bad or even emits strong bad breath, you must first confirm whether you have a problem with your mouth. If you don't brush your teeth carefully or brush your teeth in the wrong way, don't floss, and don't have the habit of washing your teeth once every six months to one year, then the food residue and bacteria in your mouth will turn into dental plaque and develop into soft dirt, that is, soft and white substances on the tooth surface that can be dug up by hand. With the passage of time, soft scale will soon be transformed into dental calculus, firmly rooted in the gingival margin, lingual side of teeth, crevices and other positions, which will not only produce a strong taste, but also lead to. According to a survey conducted by the Chinese Stomatological Association, the incidence of periodontitis in China remains high, especially among adults over 30 years old. The incidence of periodontitis has reached as high as 90%, ranging from bad breath, gingival swelling and bleeding, to tooth loosening or even falling off. In addition to gingivitis and periodontitis, oral problems such as dental caries, residual roots, residual crowns, poor repair and dentition deformity can also cause bad breath. Solution: 1 Choose your favorite toothbrush. The brush head is moderate in hardness. There are so many toothbrushes on the market, there is always one you like best. This will help to cultivate the habit of brushing your teeth carefully and enhance the fun of brushing your teeth. 2. Brush your teeth 2-3 times a day for 3 minutes each time. 3. Don't believe in miracles. Transverse pulling will not make teeth cleaner, but also cause tooth problems such as gum damage and wedge-shaped defect. 4. Use the wrist to drive the toothbrush, so that the toothbrush is inclined at 45 degrees with the tooth surface and gum edge, with gentle movements, vertical brushing and circular brushing. Refer to the following videos for details: 5. Don't miss the inside of the teeth, especially the inside of the front teeth. Brush the tongue coating lightly after brushing your teeth. 6. If the bristles are deformed or used for 3 months, a new toothbrush is needed. 7. Develop a good habit of flossing. 8. Wash your teeth every six months to one year and have an oral examination. 9. If you have a problem with your teeth, you should seek medical advice as soon as possible, and don't escape. Second, living and eating habits lead to smoking, drinking and staying up late to make your mouth stink. I believe everyone has the experience of being smoked by smokers. The chemical components in tobacco will reach the lungs through the nose and mouth, and then exhale from the lungs through the nose and mouth, forming a more unpleasant smell. Therefore, the "faint smell of tobacco" written in novels and lyrics is suspected of pulling the calf, which may only be caused by love in the passionate period. People who smoke a lot have a strong smell of smoke. Cherish life, care for relatives and friends, and smoke less. As for eating habits, it is easier to understand. Leek, green onion, garlic, snail powder, durian, onion ... are all pungent foods, and they won't leave after eating for a while, as if the whole person had been pickled. Eat raw garlic with roasted kidneys, and whoever eats bad breath will smell it on his head. Solution: 1 Quit smoking and drinking, go to bed early. Drink more water and eat fruits and vegetables. If you have an important appointment, work or meeting the next day, don't eat food with pungent smell the day before. Third, non-oral bad breath Many non-oral diseases can lead to bad breath 1. Upper respiratory tract diseases: rotten rhinitis, sinusitis, tonsillitis, pharyngolaryngitis, etc. A lot of mucus will be secreted, some of which will form nasal mucus, and the other part will flow into the pharynx along the nasal passage and be swallowed at last. In fact, everyone has to swallow a lot of snot every day, and a lot of protein in the mucus will stick to the root of the tongue and oropharynx, producing a rotten taste. 2. Gastropathy: acute or chronic gastritis, reflux esophagitis, peptic ulcer, etc. Will make the mouth sour, mostly vomiting caused by digestive problems or diseases. 3. Diabetes: Diabetic patients who eat rotten apples or nail polish remover have too many ketone bodies, which can't be metabolized in time, leading to the accumulation of acetone in the lungs, and some of them are excreted with breathing, giving off the smell of rotten apples or nail polish remover, which is characteristic and typical. 4. Liver failure: It smells like excrement. Patients with liver failure have portal hypertension and abnormal liver function. Thiol in the blood increases, and then some of it is discharged through the lungs, so the mouth is sweet, but it smells like excrement. Some people also call this smell "the smell of death". In addition to the above four kinds, uremia, leukemia, vitamin deficiency, etc. will all cause bad breath. Solution: If oral problems and eating habits are ruled out, and symptoms such as nasal congestion, runny nose, sore throat, stomach pain, indigestion, emaciation, nausea and vomiting, dry mouth and pain in a certain part of the body occur at the same time, you should go to the hospital for local or general examination and symptomatic treatment. Eat a healthy diet and eat more fruits and vegetables. If you are complained of bad breath, besides paying attention to your oral and general health, you can save face by eating citrus fruits, drinking tea, eating celery, using mouthwash and chewing gum. It is worth noting that dry mouth and decreased saliva can also lead to or aggravate bad breath. Because in a dry oral environment, bacteria will accelerate reproduction and make your mouth stink. Getting up early has a big breath, and it tastes great if you don't talk or drink water for a long time. This is a fact.
