What should I do about mouth ulcers caused by betel nut chewing?

When oral ulcers are caused by betel nut chewing, the following measures should be taken: 1. **Stop chewing betel nut**: Alkaloids such as arecoline in betel nut can irritate the oral mucosa, causing congestion, swelling, and ulcers. Therefore, it is essential to stop chewing betel nut immediately to avoid further irritation. 2. **Oral hygiene and care**: Maintain good oral hygiene through regular mouth rinsing and tooth brushing to reduce bacterial infection and promote wound healing. 3. **Medication**: For individuals experiencing significant pain or inflammation, anti-inflammatory and analgesic medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) or oral ulcer powders may be used under a doctor's guidance to alleviate symptoms and accelerate healing. 4. **Vitamin supplementation**: Oral intake of B-complex vitamins and vitamin C can support metabolic processes involved in oral tissue repair and positively aid in improving oral ulcers. 5. **Improve lifestyle habits**: Drink plenty of water and consume more fresh fruits and vegetables to provide the body with sufficient nutrients and hydration, which helps in the recovery from oral ulcers. Additionally, avoid smoking, alcohol consumption, and eating excessively hot or hard foods to prevent irritation of the ulcerated areas.
