What causes bleeding gums and dry mouth?

Bleeding gums and symptoms of dry mouth may be caused by various factors, mainly including: 1. Oral diseases: Inflammatory conditions such as gingivitis and periodontitis may result from local irritants like dental plaque and calculus, leading to redness, swelling, and bleeding of the gums. These conditions can also affect saliva secretion, causing dryness of the mouth. 2. Lifestyle habits: Poor lifestyle habits such as prolonged lack of water intake or excessive consumption of salty foods may lead to oral dryness, which can subsequently cause gum bleeding. 3. Vitamin deficiency: A deficiency of vitamin B2 in the body may cause conditions like angular cheilitis and gingivitis, resulting in bleeding gums and dry mouth. 4. Other diseases: Systemic diseases such as diabetes can also affect oral health, leading to gum bleeding and dry mouth. If you experience such symptoms, it is recommended to seek timely medical examination to determine the cause and receive appropriate treatment.
