How much toothpaste should I squeeze? Most people are wrong! The dentist's 3 tricks are cleaner and away from bad breath.

The problem of bad breath in Zhang Chengyu is always embarrassing. Many people often don't realize that they have bad breath, which makes the interviewee extremely embarrassed but embarrassed to say that it has unconsciously affected interpersonal relationships. Bad breath may also be a warning sign of too many bacteria in the mouth. Japanese dentists suggest that you just rinse your mouth with olive oil before going to bed every day, which will help prevent and improve bad breath! Don't use too much toothpaste, and don't get your toothbrush wet first. Gargling with olive oil helps to maintain oral hygiene. Japanese health programs point out that you can know if you have bad breath by brushing your toothbrush back and forth for 3 to 4 times. In addition, Yamami Kobayashi, director of RUKA Dental Clinic in Nanqingshan, Japan, suggested three ways to improve oral health and bad breath: just use a little toothpaste and 1 mouthwash. Yamami Kobayashi said that only a small amount of toothpaste can clean teeth, and only a small amount of toothpaste will make people spend more time brushing their teeth unconsciously, thus making the cleaning effect better. As long as you rinse your mouth 1 time, it will help fluoride in toothpaste stay in your mouth and help prevent tooth decay. Brush your teeth 30 minutes after meals. Don't get your toothbrush wet first. Amano Katsumi, president of Amano Dental Hospital in Japan, said that after eating, the mouth is in an acidic state, saliva will help neutralize the acidity, and calcium in it will also penetrate into the tiny gaps on the surface of teeth. If you brush your teeth immediately, it will hinder saliva and help prevent tooth decay. Therefore, you should wait for 30 minutes after eating, and brush your teeth after the acidity in your mouth is neutralized, which can prevent tooth decay. Amano also suggested that when brushing your teeth, don't wet your toothbrush first to avoid too much foam. According to the actual measurement of Japanese programs, less foam can play a better grinding effect and is more conducive to cleaning teeth. Rinse your mouth with olive oil Kobayashi said that dirt that can't be completely removed by brushing your teeth will dry out and produce odor after contact with the air, leading to bad breath. So after brushing your teeth before going to bed, you can rinse your mouth with 1 teaspoon olive oil 1 minute and spit it out. If you don't like the taste of olive oil, you can rinse your mouth with clear water again to remove the residual dirt in your mouth. Olive oil can also adhere to the surfaces of teeth and tongue, which helps to inhibit the reproduction of oral bacteria during sleep. It not only has the effect of preventing halitosis, but also may help to prevent oral diseases such as tooth decay, periodontal disease and aspiration pneumonia. The program also invited 44-year-old comedian Kato Bubu to conduct actual measurement. The standard value of halitosis is 0.37, and the initial value of Kato is 2.63. Later, after gargling with 1 week olive oil, the halitosis value actually dropped to 0.03.
