What Are Mouth Ulcers?

Mouth ulcers, also known as canker sores, are small, painful sores that develop on the tongue, gums, inner lips, or inside the mouth. They can make eating, drinking, and talking uncomfortable, but they are not contagious. While most ulcers heal within 7 to 14 days, large or frequent mouth ulcers may be a sign of an underlying medical condition.

Common Causes of Mouth Ulcers

There are several possible causes of mouth ulcers, including:

• Stress or anxiety
• Minor mouth injuries from sharp teeth, braces, or hard food
• Vitamin B12, iron, or folic acid deficiency
• Hormonal changes
• Food allergies or acidic foods
• Poor oral hygiene
• Certain medicines like painkillers or beta blockers

Symptoms to Watch Out For

Common symptoms of mouth ulcers include:

• Small round or oval sores with a white or yellow center
• Redness or swelling around the ulcer
• A burning or tingling sensation before the sore appears
• Pain while chewing, swallowing, or brushing
• In some cases, fever and swollen lymph nodes

Treatment and Home Remedies

Most mouth ulcers heal naturally, but some home remedies can speed up recovery and reduce pain:

• Rinse your mouth with warm salt water twice daily
• Apply honey or coconut oil directly on the ulcer for faster healing
• Avoid spicy, hot, or acidic foods
• Use an antiseptic medicated mouthwash
• Use over-the-counter gels containing benzocaine or lidocaine for pain relief

If ulcers don’t heal within two weeks, consult a dentist or doctor for further evaluation.

How to Prevent Mouth Ulcers

You can prevent mouth ulcers by following these healthy habits:

• Maintain good oral hygiene
• Eat a balanced diet rich in vitamins and minerals

When to See a Doctor

You should see a doctor if:

A doctor may suggest vitamin supplements, medicated mouthwash, or tests to check for other conditions like oral infections or nutritional deficiencies.
