What causes dry mouth and bad breath?

In daily life, when we feel dry mouth, we will choose to drink more water, but have you ever found that sometimes even if you drink a lot of water, you still have dry mouth symptoms, and even cause bad breath. So, what is the reason for dry mouth and bad breath? I will find the reason for you.

1. Oral diseases:

People with oral diseases such as caries, gingivitis, periodontitis, oral mucositis, tooth decay, and periodontal disease are prone to the growth of bacteria in their mouths, especially anaerobic bacteria, which decompose to produce sulfides, emit a putrid smell, and cause bad breath.

2. Vitamin B2 deficiency:

When the body lacks vitamin B2, it can also cause dry mouth, as well as symptoms such as oral ulcers, dry throat, and tongue ulcers.

3. Gastrointestinal diseases

For example, peptic ulcer, chronic gastritis, functional dyspepsia, etc. may be accompanied by bad breath. Recently, we have also found that the incidence of bad breath in patients infected with Helicobacter pylori, which causes many gastric diseases, is significantly higher than that of uninfected patients. After the eradication of Helicobacter pylori, the symptoms of bad breath are significantly alleviated.
