What causes sour mouth when eating?

I believe everyone has experienced this situation: after eating, if you don’t brush your teeth in time to clean your mouth, you will feel that the inside of your mouth is very sour. Since the sour feeling inside the mouth does not have much impact on a person's body, most people ignore the occurrence of this situation. But some people with a curiosity for knowledge still want to know why eating causes sour mouth.

1. The most common non-pathological situation is having just eaten sweets.

Because there is a kind of lactic acid bacteria in our mouth, it will ferment and produce lactic acid after eating sweets. The lactic acid content increases as the sugar stays in the mouth for a longer time. In addition, sweets will increase the secretion of gastric acid, causing gastric acid in the mouth. Therefore, after eating sweets, there will be a sour feeling in the mouth.

This situation is easy to handle:

1. After eating sweets, rinse your mouth several times with tap water or light salt water.

2. If conditions permit, it is best to brush your teeth in time.

After eating, rinsing your mouth promptly can keep your oral cavity in good condition, reduce bacteria and food residues, and keep your breath fresh.

2. If this situation has never occurred before and only happens once or twice suddenly, it may be caused by catching a cold. After catching a cold, gastric acid and saliva secretion are more than usual. The gastric juice and saliva will break down the starch in the mouth into sugars, and then form acidic substances.

In this case:

1. Keep warm and drink plenty of hot water.

2. It is recommended not to eat cold drinks or the like.

3. Don’t eat sweets and cold drinks together.

3. If this situation has not occurred before, but has occurred frequently in recent period, it may be caused by recent indigestion or stomach fire.

Indigestion of food usually leads to accumulation of toxins in the body, causing symptoms such as bad breath and constipation. It can be judged based on whether there are other symptoms.

In this case:

1. Eat more whole grains;

2. Take some health care products that promote digestion;

3. Pay attention to drinking light and easily digestible drinks, and eat less raw, cold, greasy and irritating foods.

4. If you often feel sour taste in your mouth, it may be a stomach disease such as gastritis or peptic ulcer.

Traditional Chinese medicine believes that "liver heat causes sour mouth" and "weak spleen and stomach qi, wood takes over the earth position and causes sour mouth", so sour mouth is mostly caused by spleen deficiency and excessive liver fire. Some people have measured the saliva of patients with oral acidosis and found that the levels of lactate, phosphatase and carbonic anhydrase were higher than those of normal people, and the pH was more acidic.

1. It is necessary to go to the hospital for pathological examination in time and take Chinese or Western medicine for treatment.

2. Pay attention to maintaining the liver, spleen and stomach in your daily diet.

5. If our diet is very healthy but the problems mentioned above still occur, we should consider whether there is a disease in our oral cavity.

Oral hygiene problems may also cause a sour mouth when eating. You can check your oral hygiene and rinse your mouth in time.
