What causes a little bad breath? Is it an accumulation of food?

A little bad breath for two or three days may be caused by non-pathological factors such as improper diet and poor oral hygiene, or it may be caused by pathological factors such as indigestion and periodontitis. Patients need to be treated according to the cause.

1. Physiological factors

1. Improper diet: If you have recently eaten too much spicy and irritating food or overeaten, you may have gastrointestinal disorders, which will cause symptoms of bad breath. It is recommended to pay attention to a light diet, avoid eating too much greasy food, and eat more fresh vegetables and fruits, which can promote gastrointestinal peristalsis and improve symptoms.

2. Poor oral hygiene: If you don't pay attention to oral hygiene and don't brush your teeth and rinse your mouth in time, it will lead to food residues remaining in the mouth, which will breed bacteria and produce odors. Therefore, it is necessary to develop good living habits, rinse your mouth in time after meals, and insist on brushing your teeth in the morning and evening.

2. Pathological factors

1. Indigestion: If you eat indigestible foods for a long time, such as fried chicken, fatty meat, etc., it will increase the burden on the gastrointestinal tract and affect the normal digestion and absorption capacity, which will also induce the above conditions. Under the guidance of a doctor, you can take drugs such as stomach digesting tablets and lactobacillus tablets to relieve symptoms.

2. Periodontitis: It is usually a disease caused by the infection of pathogenic bacteria caused by the tooth due to lack of attention to personal hygiene, and symptoms such as redness and swelling of the gums and pain will occur during the onset of the disease, and even accompanied by bad breath.At this time, it can be treated by scaling, or it can be rinsed with metronidazole gargle as prescribed.

In addition, it may also be related to tooth decay, so it is recommended to go to the hospital to determine the cause through relevant examinations before treatment.
