Mouth Ulcers | Causes, Types & Effective Treatment Options

Mouth ulcers (also known as oral ulcers or canker sores) are small, painful sores that appear inside the mouth—on the cheeks, lips, tongue, gums, or palate. While most ulcers heal on their own, recurrent or long-lasting ulcers may indicate vitamin deficiencies, infections, stress, sharp teeth, or underlying medical conditions.

At our clinic, we provide accurate diagnosis and advanced treatment options to relieve pain, promote healing, and prevent frequent recurrences.

Types of Mouth Ulcers

  1. Aphthous Ulcers (Canker Sores)
    The most common type. Painful, round or oval ulcers with a yellow‑white center.
    Minor: Small, heal in 7–10 days • Major: Larger, deeper, may leave scars • Herpetiform: Multiple tiny ulcers merging together
  2. Traumatic Ulcers
    Caused by biting the cheek, sharp teeth, braces, ill‑fitting dentures, or accidental trauma.
  3. Viral Ulcers
    Seen in viral infections such as herpes simplex, hand‑foot‑mouth disease, etc.
  4. Ulcers Due to Deficiencies
    Caused by lack of Vitamin B12, iron, folic acid, or anemia.
  5. Ulcers Linked to Systemic Conditions
    Associated with stress, acid reflux, hormonal imbalance, gastrointestinal disorders, and autoimmune diseases. Needs professional evaluation.

Frequently Asked Questions (FAQs) About Mouth Ulcers

1. What are mouth ulcers?

Mouth ulcers (canker sores/oral ulcers) are small, painful sores that develop on the inner cheeks, tongue, lips, or gums. They are usually harmless but can be very uncomfortable.

2. What causes mouth ulcers?

Common causes include:

  • Stress and lack of sleep
  • Vitamin B12, iron, or folic acid deficiency
  • Accidental biting
  • Sharp teeth or braces
  • Spicy or acidic foods
  • Viral infections
  • Hormonal changes
  • Dry mouth
  • Food allergies
  • Autoimmune disorders

A proper evaluation helps identify the exact cause.

3. Are mouth ulcers contagious?

Most mouth ulcers (especially aphthous ulcers) are not contagious. Viral ulcers—such as those from herpes—can be contagious and need specific treatment.

4. How long do mouth ulcers take to heal?

Minor ulcers heal in 7–10 days, while major or recurrent ulcers may take longer. If an ulcer doesn’t heal within 2 weeks, you should see a dentist.

5. When should I worry about a mouth ulcer?

Seek professional care if the ulcer:

  • Lasts longer than 14 days
  • Recurs frequently
  • Is unusually large or very painful
  • Occurs with fever or swollen glands
  • Is associated with weight loss or fatigue
  • Does not respond to home remedies

Persistent ulcers may indicate an underlying condition.

6. How are mouth ulcers treated?

At our clinic, treatment may include:

  • Medicated gels and mouthwashes
  • Vitamin supplements
  • Laser therapy for instant relief
  • Adjusting sharp teeth or braces
  • Antiviral or antifungal medication (if needed)
  • Dietary and lifestyle guidance

Treatment depends on the cause and severity.

7. Can stress cause mouth ulcers?

Yes. Stress and lack of sleep are major triggers for recurrent mouth ulcers.

8. Do certain foods trigger mouth ulcers?

Yes. Common triggers include:

  • Spicy foods
  • Citrus fruits
  • Tomato-based foods
  • Nuts
  • Chocolate
  • Gluten (in some individuals)

Avoiding triggers helps prevent recurrence.

9. Can mouth ulcers be prevented?

Prevention includes:

  • Proper brushing and flossing
  • Managing stress
  • Treating sharp teeth or faulty fillings
  • Taking vitamin supplements if deficient
  • Staying hydrated
  • Avoiding trigger foods

Regular dental check-ups can prevent repeated ulcers.

10. Are mouth ulcers related to digestive problems?

Yes. Gastric acidity, IBS, celiac disease, and inflammatory bowel conditions may trigger recurrent oral ulcers. Professional evaluation helps rule out systemic issues.

11. Do mouth ulcers come from poor hygiene?

Not always. While poor hygiene can cause bacterial buildup, many ulcers result from deficiency, stress, allergies, or immunity-related conditions.

12. Can children get mouth ulcers?

Yes. Children commonly develop ulcers due to accidental biting, viral infections, nutritional deficiencies, or stress from school. Treatment is safe and effective for kids.

13. Is laser treatment safe for mouth ulcers?

Yes. Laser therapy provides instant pain relief, reduces healing time, and is completely safe and non-invasive.

14. Should I stop using toothpaste when I have an ulcer?
