What should I do about drooling and bad breath during sleep?

Drooling during sleep accompanied by bad breath may be caused by various factors, including improper sleeping posture, oral ulcers, gingivitis, dental caries, periodontitis, and other oral problems, as well as digestive system disorders such as gastroesophageal reflux disease. To address this issue, the following measures can be taken: 1. Adjust sleeping position: Avoid lying on one side for prolonged periods to reduce facial pressure and saliva accumulation. 2. Maintain good oral hygiene: Brush teeth in the morning and evening, rinse mouth after meals, and use fluoride-containing mouthwash to kill oral bacteria and reduce bad breath. 3. Treat oral conditions: Seek timely medical attention for issues such as oral ulcers or gingivitis, and follow medical advice regarding appropriate medication. 4. Improve dietary habits: Avoid spicy and irritating foods; consume more fresh fruits and vegetables to maintain gastrointestinal health. 5. Medication: If a digestive disorder such as gastroesophageal reflux is suspected, treatment with medications like omeprazole enteric-coated tablets may be used under a doctor's guidance.
