What's wrong with night pain?

1. Poor oral hygiene

If you don't brush your teeth carefully before going to bed at night, you don't pay attention to oral hygiene at ordinary times. Food residues ferment in the mouth and breed bacteria, which may lead to bitter taste in the mouth at night.

2. Bad prostheses

If there are bad prostheses in the mouth, such as irregular root canal treatment, unqualified dental filling materials, etc., it is easy to cause bitter taste in the mouth of patients at night.

3. Bile reflux

such

as acute cholecystitis, biliary stones, duodenal ulcer and other diseases may lead to bile reflux. Long-term bile reflux is easy to cause bitter taste in the mouth of patients.
