Brushing my teeth every morning and evening, why do I still have bad breath?

When bad breath occurs, it may be related to poor oral hygiene, tooth decay, gingivitis, etc. Gastrointestinal disorders can also lead to bad breath.

1. Oral factors

1. Poor oral hygiene: If you do not pay attention to the cleanliness and hygiene of the oral cavity in daily life, food residues will accumulate on the teeth, thus breeding bacteria and causing bad breath;

2. Tooth decay: When the patient has tooth decay, it will cause holes on the surface of the teeth, which is easy to leave food residues after eating, and will also cause bacteria to multiply and cause bad breath;

3. Gingivitis: Due to inflammation and stimulation, the gums can be red, swollen and congested, and will be accompanied by obvious pain and bleeding symptoms, as well as bad breath.

2. Gastrointestinal factors

If you have a stomach disease such as chronic gastritis or peptic ulcer, it will affect the normal digestive function, and may even induce reflux esophagitis, in which the stomach contents pass through the esophagus and enter the throat, so bad breath may occur.

3. Other reasons

In addition, if you smoke or drink alcohol regularly, it may have an adverse effect on the oral mucosa, resulting in a peculiar smell, which can cause symptoms of bad breath.

It is recommended that patients go to the hospital for examination and treatment in time, and if it is caused by oral diseases, they can use mouthwash to relieve it according to the doctor's instructions, such as compound chlorhexidine gargle. At the same time, it is also necessary to do a good job of cleaning the mouth and develop a good habit of rinsing the mouth after meals.
