Through extensive research, scientists have found that tongue coating and periodontal disease are the main causes of breath, and our traditional oral care method that focuses on brushing often ignores these parts.

Bad breath can be divided into physiological and pathological. When we eat foods such as green onions and garlic that emit a strong irritating smell, the breath produced in our mouths is physiological, and this taste is temporary; pathological bad breath is mostly related to the gas released by bacteria when they decompose organic matter, and its appearance also reminds that our body may need your attention.

1. The main source of tone

1. Bacterial decomposition of food residues

Scientists have found through a large number of studies that tongue coating and periodontal disease are the main causes of tone, and our traditional oral care method that mainly brushes teeth often ignores these parts.

Bacteria gathered together at the root of the tongue and periodontal bags, which were easy to colonize, forming a breeding ground for anaerobic bacteria and microaerobic bacteria in the oral cavity.

study found that the composition of bacteria in tongue coating is very complex, and the bacteria in each population may have different characteristics. If the bacteria in your mouth just happen to be like to produce gases such as hydrogen sulfide , the result is conceivable. scientists studied and analyzed the tongue coating of patients with "breathing" and found that about 60% of patients' breath source is at one-third of the tongue coating. When brushing teeth and cleaning the tongue coating, breath troubles can be greatly improved.

2, Helicobacter pylori

The oral cavity is the window of the digestive system, and the production of tone may also come from bacterial infection in the stomach. However, due to the presence of gastric acid, it is unlikely that bacteria generally want to survive in the stomach.

But there is a bacteria called Helicobacter pylori that is naturally acid-resistant. It is one of the few bacteria that can survive in the stomach. Its reproduction and growth in the stomach may cause diseases such as gastric ulcers and .

3, smoking

In addition to bacterial infection, smoking is also closely related to having a breath. This may be related to the sulfur-containing compounds in the smoke, or it may also cause changes in the oral environment due to smoking, which is conducive to bacterial growth. Of course, another reason is that smoking can cause gum disease, which can induce breath.

2. How to solve the problem of bad breath?

First of all, the most important thing is naturally to maintain oral hygiene. remember the word "oral" and don't just focus on brushing your teeth. Brush your teeth with fluoride toothpaste every morning and evening. The most important thing is to brush the tongue surface lightly. As long as you clean the tongue surface and add the effect of mouthwash, you can clean the entire oral environment to the greatest extent.

Secondly, on the basis of good oral care, developing a healthy lifestyle is also a prerequisite for maintaining a fresh tone. For example, staying away from tobacco and unclean food, paying attention to a balanced and reasonable diet can effectively prevent diseases such as periodontitis and Helicobacter pylori infection that are closely related to embarrassing tone.

In addition, scientific research shows that 's practice of improving breath by chewing gum is just a stopgap measure and does not solve the fundamental problem. chewing sugar-free chewing gum can indeed block bad odor at the beginning, but after 3 hours, whether it smells or sulphide monitoring values are no different from chewing gum. In addition, those chewing gums that use syrup as sweetener may also cause other oral problems such as caries .
