What is the reason for a sour taste in the mouth

A sour taste in the mouth may be caused by ulcers or periodontitis inside the mouth, or it may be caused by indigestion, and it is also related to dampness and heat in the spleen and stomach.

1. Ulcers inside the mouth: Eating spicy or greasy food frequently may cause internal inflammation, which may cause oral ulcers. If you do not pay attention to the hygiene of the oral area, it may also cause bad breath in the mouth.

2. Periodontitis: Not having a good habit of brushing teeth will cause food debris to remain in the gaps between teeth, which can easily breed bacteria and cause periodontitis. It is possible that this will cause bad breath and symptoms of halitosis.

3. Indigestion: Frequent overeating or eating indigestible food may cause indigestion in the body, which usually causes food to stagnate in the stomach and rot, and there will be a sour taste in the mouth.

4. Damp-heat in the spleen and stomach: Damp-heat in the spleen and stomach will usually result in hydrogen being unable to rise and turbid air being unable to descend, thus causing sour mouth. The improvement effect can be achieved by drinking water soaked with medicinal materials such as malt and honey.

When a sour taste appears in the mouth, you should pay attention to keeping your diet light and easily digestible, avoid eating spicy and irritating foods, and do not eat healthy foods. Develop good brushing habits, use a soft-bristled toothbrush, and brush your teeth using the Bass brushing method.
