Why do people have bad breath when they sleep, why do they have bad breath as soon as they wake up,

Because there is food residue in the mouth, in the closed environment of the mouth, through the secretion of saliva, the food is thought to be a fermentation process, so the mouth will feel smelly. You should insist on brushing your teeth in the morning and evening, and rinse your mouth after meals, so that the protection of your teeth is more in place, and your mouth will not smell so much.

Smelly mouth when sleeping is a common symptom, mainly due to the presence of a certain amount of bacteria in the mouth itself, when sleeping, the chewing and swallowing function of the mouth is weakened, and the bacteria in the mouth multiply rapidly, coupled with the relatively small flow of saliva, the saliva becomes viscous, at this time the bacteria increase, the secretion increases, and there will be symptoms of bad breath.

When you sleep, the saliva secretion decreases, and the amylase in the saliva also decreases accordingly, and the killing effect on bacteria is reduced, so bacteria (don't think that the inside of the mouth is very clean, in fact, there are resident flora) breed in large quantities, and metabolize the production of amines to emit odors.

The landlord feels bad breath, it may be a stomach fire. You can go to the pharmacy to buy honeysuckle, chrysanthemums soaked in water and drink the fire. Rinse your mouth with clove.

Because the temperature in the mouth is about 37 degrees, the food you eat is sometimes not brushed clean in the root of the teeth, and there are bacteria in the mouth, which will ferment after a long time, so the mouth will have a little taste.

There are many types of bad breath, some brush your teeth at night, and there are food residues between your teeth, and after one night, bad breath will form. And bad teeth. And whether you have any stomach diseases. are all causes of bad breath. Rule it out for yourself.

Bad breath is mostly caused by oral problems, and the other reason is that stomach fever is the most common cause. Actively go to the hospital to check the cause and then treat the symptoms**. Brushing your teeth after each meal and eating fruit before meals can help avoid or reduce bad breath.

Because the mouth is closed when you sleep, the leftover food in the mouth will ferment, so some flavor will develop. Brush your teeth more before going to bed and this will reduce a lot of light.

This is because the food for dinner is digested and broken down in the stomach and esophagus.

Bad mouth is that the teeth and mouth are not cleaned before going to bed, and the food residue will ferment after sleep to produce bacteria, causing the mouth to smell, and the second is because of physical health. In this way, it is necessary to go to the hospital to check the physical condition and prescribe the right medicine.

You say why people sleep with a very bad mouth, generally bad breath is divided into oral cavity and stomach and intestines, unhygienic oral health will also cause bad breath, bad stomach will also cause bad breath, you have to go to the doctor to consult clearly, and then according to which one is caused and then prescribe the right medicine.

If you wake up every day and feel bad breath, then you need to pay attention! In addition to brushing your teeth every day, try mouthwash, dental floss, and tonklee finger covers. If it still doesn't work, you must go to the doctor in time to see if there is a problem with your stomach.

There is a fire in the stomach, and the rise and fall are out of balance, just lower the fire.

Bad breath is not an independent disease, but a condition caused by physical discomfort. If you want to get rid of bad breath, the method should be comprehensive.

1. Maintain oral hygiene. Brush your teeth morning and evening to keep them clean. Don't forget to brush your tongue when brushing your teeth, as your tongue contains a lot of fermentable food bacteria.

2. Eat more vegetables and fruits. Vegetables contain a lot of fiber, which can help digestion and prevent constipation. Vegetables and fruits also benefit gum health and drain excess mucosal secretions from the mouth.

3. Drink plenty of water, or lemonade. Adequate hydration keeps the cells in the body alive. Water keeps the mouth moist and prevents bad breath caused by fermented food.

4. Tea deodorization method. After eating garlic and onions, there is a peculiar smell in the mouth, and you can chew some tea leaves to eliminate bad breath.

5. Rinse your mouth with salt water. Gargling with salt water destroys oral bacteria and thus bad breath.

Smokers are like this, and their mouths stink when they wake up in the morning!

Basically, if it is a bad smell in the mouth, it is generally caused by the decomposition of filth by bacteria in the mouth overnight, etc., and it is not a big problem, everyone has it.

However, if you still feel a bad smell in your esophagus on an empty stomach after brushing your teeth, you may need to see a gastroenterologist, and you may have stomach problems or are prone to food accumulation. In addition, it is easy to cause odors when it is on fire.

Although not everyone wakes up with a smelly mouth, but for a large number of people, it is normal to have bad breath in the morning, even if you brush your teeth the night before and go to sleep, after a night, there will still be a lot of bacteria in the mouth, resulting in changes in the oral environment, making people have bad breath. So, how to solve the phenomenon of bad breath.

Drink tea. For people who often have bad breath, the first thing you need to pay attention to in your daily life is to drink some tea often, which is more significant for you to relieve bad breath, which is mainly because tea contains more tea polyphenols, and this substance is more significant for cleaning the mouth and removing the odor in the mouth.

People who suffer from bad breath must pay attention to cleaning their teeth in daily life, so as not to let bacteria grow in the mouth and cause bad breath to worsen.

It may be that after eating before going to bed, the remaining food residues are left between the teeth, which cannot be digested, and if you don't brush your teeth, these residues can only be between the teeth, and you may not smell before going to bed, but after waking up, the taste will be greater, because the food residues will ferment in the teeth, and there are other microorganisms and bacteria. Therefore, it is not recommended to eat half an hour before going to bed, and you should brush your teeth and rinse your mouth in time after eating. Because when you sleep at night, the various organs of the body are also in a dormant state, and the digestive function is weakened, which is neither good for health nor conducive to digestion.

The above is my personal opinion and I hope it helps.
