How to treat mouth ulcers after tooth extraction?
Mouth ulcers (canker sores) can develop after a tooth extraction, often due to stress on the tissue or accidental trauma during eating. They usually heal on their own within 7–14 days. To soothe discomfort, rinse gently with warm salt water (½ teaspoon salt in a cup of water) 2–3 times a day, avoid spicy or acidic foods, and take over‑the‑counter pain relievers if needed.
If the ulcer is directly over the extraction site or accompanied by worsening pain, fever, or pus, it may be a sign of infection or dry socket rather than a simple ulcer. In that case, contact your dentist. For persistent ulcers that do not improve after two weeks, a dental evaluation is recommended. Do not apply topical anaesthetics without your dentist’s advice, as they can mask important symptoms.
• Most mouth ulcers heal within 7–14 days with salt water rinses and gentle care
• Avoid spicy, acidic, or rough foods that can irritate the ulcer
• Contact your dentist if the ulcer is near the extraction site and pain worsens or if you have fever
