Rinse with warm salt water (1/2 teaspoon salt in a cup of warm water) 3–6 times daily
Rinse with baking soda solution (1/2 teaspoon baking soda in a cup of water) 3–4 times daily
Apply honey (especially raw honey) directly to the ulcer 2–3 times daily
Dab with aloe vera gel (pure, preservative-free if possible) 2–3 times daily
Use a cold compress on the area for 5–10 minutes to reduce pain
Avoid spicy, acidic, salty, and very hot foods until healed
Choose soft, bland foods (yogurt, oats, soups, mashed foods)
Avoid alcohol-based mouthwashes and smoking/vaping
Keep the mouth clean with gentle brushing and flossing
Use a soft toothbrush and avoid aggressive brushing over the sore
Stay hydrated and consider sugar-free chewing gum to stimulate saliva
Consider OTC protective oral gels/pastes (e.g., benzocaine or protective barriers) if you want faster relief
If you suspect a trigger, avoid it (e.g., certain toothpaste/whitening products, hard/rough foods)
If ulcers persist more than 10–14 days, are very large, recur frequently, or are accompanied by fever or swollen neck glands, seek medical/dental care
Seek urgent care if you have trouble swallowing, severe pain, spreading sores, or you’re immunocompromised
