Always look at your cell phone, you may have bad breath. Really? What's the reason
Is it true that people always look at mobile phones and may have bad breath
Recently, it was reported that Japanese stomatologist Takeshi Nakai said that he would have bad breath if he played with his mobile phone for more than half an hour.
A stone arouses a thousand waves, many people can not help but want to ask, why is this?
'there's a scientific basis for that. "Chen Weiqing explained that the smell in the mouth is related to people's lifestyle. When you look at your cell phone, you will look down. This posture will reduce saliva secretion. At the same time, if you don't speak to anyone when you look at your mobile phone, your jaw doesn't move, and you don't swallow, you won't be able to stimulate saliva secretion, and the metabolites of oral bacteria stay in your mouth. In the condition of insufficient saliva for 30 minutes, the bacteria causing halitosis will increase, which will lead to halitosis.
Chen Weiqing said that nowadays, there are more and more bow headed ethnic groups, from middle-aged and elderly people to primary and secondary school students, who are using mobile phones to buy online, watch TV dramas, play mahjong, play games and so on. They are more prone to halitosis than ordinary people.
"In order to prevent halitosis when looking at the phone, proper oral movement is required. "Chen Weiqing said that the upper and lower teeth were occluded and the chin moved 30 times, so that the mouth would secrete saliva. Saliva has a natural bactericidal effect and can also help to remove food residues.
How to see if you have bad breath
1. Lick the back of your hand with your tongue. After 10 seconds, when your mouth dries, smell if you have bad breath.
2. Cover your nose and mouth with your hands at the same time, and you can easily know your breath status.
3. Wipe the inside of your tongue with gauze or cotton swab. If it turns yellow, you may have bad breath.
4. Use a mirror to see the color of your tongue. A white inside means bad breath.
5. Use floss to clear the teeth. If floss has smell, it means that you have bad breath.
What causes halitosis
Generally speaking, there are several factors that cause bad breath in the mouth. First, oral problems, such as caries, gingivitis, periodontitis, oral mucositis, cavities, periodontal diseases and other oral diseases, are easy to breed bacteria in the mouth, especially anaerobic bacteria, which decompose to produce sulfides, give off the smell of corruption, and produce halitosis.
Second, bad oral hygiene, not brushing your teeth sooner or later, smoking, drinking alcohol, drinking coffee, eating spicy irritants such as onions, garlic, leeks, or eating stinky food such as stinky tofu, stinky salted eggs can also cause halitosis.
Third, patients with gastrointestinal diseases, such as peptic ulcer, chronic gastritis, functional dyspepsia, etc., may be accompanied by halitosis. Moreover, the incidence of halitosis in many patients with Helicobacter pylori infection is significantly higher than that in uninfected patients. The reason is that H. pylori produces sulfide directly, which causes halitosis.
Fourthly, dieting to lose weight, or being unable to eat due to illness, or the function of salivary glands of the elderly is reduced, and the endocrine disorder of women during menstruation leads to the decrease of salivary secretion, which is conducive to the growth of anaerobic bacteria and lead to halitosis.
Nowadays, due to the improper way of life, it has become another major cause of halitosis, but it is often overlooked. We should pay attention to oral cleaning and exercise, and maintain oral 'ecological environment' with healthy living habits.
