Mouth Ulcer Types

Minor Ulcers:

  • These are the most common type of mouth ulcers.
  • Typically small in size, usually less than 1 centimeter in diameter.
  • Minor ulcers are shallow, with a white or yellowish center and a red border.
  • They usually heal within one to two weeks without scarring.

Major Ulcers:

  • Less common but more severe than minor ulcers.
  • Larger in size, often more than 1 centimeter in diameter.
  • Major ulcers are deeper and can be extremely painful.
  • Healing may take several weeks, and scarring is possible.

Herpetiform Ulcers:

  • These ulcers are characterized by multiple tiny lesions that cluster together.
  • Despite their name, herpetiform ulcers are not caused by the herpes virus.
  • They can be very painful and may persist for several weeks.
  • However, they usually heal without scarring.

Traumatic Ulcers:

  • These ulcers are caused by physical trauma to the mouth, such as accidentally biting the inside of the cheek or lip.
  • Traumatic ulcers are often irregular in shape and may be accompanied by swelling.
  • Healing typically occurs within a week once the source of trauma is removed.

Infectious Ulcers:

  • Caused by infections, such as oral thrush (a fungal infection) or herpes simplex virus.
  • These ulcers may present with additional symptoms such as fever, swollen lymph nodes, or systemic illness.
  • Treatment often involves addressing the underlying infection with antifungal or antiviral medications.

Systemic Disease-Related Ulcers:

  • Some systemic diseases, such as inflammatory bowel disease, Behçet’s disease, or autoimmune disorders, can manifest with mouth ulcers as a symptom.
  • These ulcers may be recurrent and resistant to conventional treatment.
  • Management typically involves addressing the underlying systemic condition in addition to managing the ulcers themselves.

Mouth Ulcer Causes


  • Accidental biting of the inside of the cheek, lip, or tongue.
  • Injury from dental appliances, such as braces or ill-fitting dentures.
  • Physical irritation from sharp edges of broken teeth or dental work.

Stress or Emotional Factors:

  • Psychological stress or anxiety can weaken the immune system, making the mouth more susceptible to ulcers.
  • Emotional stressors such as grief, depression, or trauma may trigger ulcer formation.

Nutritional Deficiencies:

  • Inadequate intake of essential nutrients like vitamin B12, iron, folic acid, or zinc.
  • Malabsorption disorders such as celiac disease or Crohn’s disease can lead to nutrient deficiencies and subsequently mouth ulcers.

Food Sensitivities:

  • Allergic reactions or sensitivities to certain foods, such as citrus fruits, chocolate, nuts, or spicy foods, may trigger ulcer formation.

Hormonal Changes:

  • Fluctuations in hormone levels during menstruation, pregnancy, or menopause can predispose individuals to mouth ulcers.

Autoimmune Conditions:

  • Conditions like Behçet’s disease, systemic lupus erythematosus (SLE), or pemphigus vulgaris involve the immune system mistakenly attacking healthy tissues, including the lining of the mouth.


  • Viral infections like herpes simplex virus (HSV) or bacterial infections such as Helicobacter pylori can cause mouth ulcers.
  • Fungal infections like oral thrush (caused by Candida albicans) can also contribute to ulcer formation.


  • Some medications, including nonsteroidal anti-inflammatory drugs (NSAIDs), beta-blockers, or chemotherapy drugs, can cause oral mucosal irritation and ulceration as side effects.

Mouth Ulcer Symptoms


  • Mouth ulcers often cause discomfort or pain, especially when eating, drinking, or speaking.

Redness and Inflammation:

  • The area around the ulcer may appear red and swollen.

Round or Oval Sores:

  • Ulcers typically present as round or oval-shaped sores with a white or yellow center and a red border.


  • The affected area may be sensitive to touch or pressure.

Difficulty Eating:

  • Due to pain and discomfort, individuals may have difficulty eating certain foods.

Tingling or Burning Sensation:

  • Some people experience a tingling or burning sensation before the ulcer appears.


  • In severe cases or if the ulcer becomes infected, fever may occur.

Enlarged Lymph Nodes:

  • Swelling of the lymph nodes in the neck may occur if the body is fighting off an infection associated with the ulcer.


  • Most mouth ulcers heal within 1-2 weeks. If an ulcer persists for more than 2 weeks or recurs frequently, medical attention may be necessary to rule out underlying conditions.

Risk Factors for Mouth Ulcer


  • Psychological stress or anxiety can weaken the immune system and increase the likelihood of developing mouth ulcers.


  • Accidental bites, cuts, or injuries to the mouth from sharp foods or dental work can trigger the formation of ulcers.

Hormonal Changes:

  • Fluctuations in hormone levels, such as those occurring during menstruation, pregnancy, or menopause, may contribute to the development of mouth ulcers.

Dietary Factors:

  • Consuming certain foods and beverages, such as spicy or acidic foods, citrus fruits, chocolate, coffee, and tea, can irritate the lining of the mouth and lead to ulcer formation.

Nutritional Deficiencies:

  • Deficiencies in essential nutrients like vitamin B12, iron, and folate can weaken the immune system and increase susceptibility to mouth ulcers.

Oral Hygiene:

  • Poor oral hygiene practices, including inadequate brushing, flossing, and mouth rinsing, can create an environment conducive to the development of ulcers.

Medical Conditions:

  • Underlying medical conditions such as autoimmune diseases (e.g., Crohn’s disease, celiac disease), viral infections (e.g., herpes simplex virus), and gastrointestinal disorders (e.g., inflammatory bowel disease) may predispose individuals to recurrent mouth ulcers.

Diagnosis of Mouth Ulcer

Medical History:

  • The healthcare provider will begin by taking a detailed medical history, including information about the onset, duration, and frequency of mouth ulcers, as well as any associated symptoms or triggers.

Physical Examination:

  • A thorough examination of the oral cavity will be conducted to assess the size, location, and appearance of the ulcers. Special attention will be given to any signs of infection or inflammation.

Laboratory Tests:

  • In some cases, blood tests may be recommended to evaluate for underlying medical conditions or nutritional deficiencies that may be contributing to the development of mouth ulcers.


  • A biopsy may be performed if the ulceration appears unusual or if there is concern about the possibility of oral cancer. During a biopsy, a small sample of tissue is taken from the ulcer and examined under a microscope for further evaluation.

Allergy Testing:

  • Allergy testing may be considered if there is suspicion that certain foods, medications, or oral care products may be triggering the ulcers.

Imaging Studies:

  • In rare cases, imaging studies such as dental X-rays or computed tomography (CT) scans may be ordered to evaluate for underlying dental or bone abnormalities associated with the ulcers.

Referral to Specialist:

  • Referral to a dental specialist or oral and maxillofacial surgeon may be necessary for further evaluation and management of complex or persistent mouth ulcers.

Mouth Ulcer Management

Home Care Remedies:

  • Topical Treatments: Over-the-counter topical gels, creams, or mouth rinses containing ingredients such as benzocaine, lidocaine, or hydrogen peroxide can help relieve pain and promote healing.
  • Saltwater Rinse: Gargling with warm saltwater several times a day can help soothe the ulcer and keep the area clean.
  • Avoid Irritants: Avoiding spicy, acidic, or rough-textured foods that can irritate the ulcer and prolong healing.
  • Maintain Oral Hygiene: Brushing teeth gently with a soft-bristled toothbrush and using alcohol-free mouthwash can help keep the mouth clean and prevent infection.


  • Pain Relief: Over-the-counter pain relievers such as acetaminophen or ibuprofen can help alleviate pain and discomfort associated with mouth ulcers.
  • Prescription Medications: In some cases, prescription medications such as corticosteroids or antiviral drugs may be prescribed to reduce inflammation or treat underlying infections.

Lifestyle Changes:

  • Stress Management: Practicing stress-reduction techniques such as meditation, deep breathing exercises, or yoga may help reduce the frequency and severity of mouth ulcers.
  • Dietary Modifications: Avoiding trigger foods or substances such as spicy foods, acidic fruits, and tobacco can help prevent recurrent ulcers.
  • Hydration: Drinking plenty of water and staying hydrated can help promote healing and prevent dehydration, especially in cases of severe oral ulceration.

Professional Treatment:

  • Cauterization: In severe or persistent cases, a healthcare provider may recommend cauterizing the ulcer with a chemical agent to promote healing.
  • Steroid Therapy: Corticosteroid medications may be injected directly into the ulcer to reduce inflammation and speed up healing.
  • Antibiotics: If the ulcer is caused by a bacterial infection, a course of antibiotics may be prescribed to clear the infection.
  • Dental Procedures: In cases where underlying dental issues are contributing to the ulcers, dental procedures such as filling cavities or extracting teeth may be necessary for resolution.

Follow-up Care:

  • Monitoring: Regular follow-up appointments with a healthcare provider or dentist may be recommended to monitor the healing progress of the ulcer and adjust treatment as needed.
  • Preventive Measures: Practicing good oral hygiene, avoiding known triggers, and managing underlying medical conditions can help prevent recurrence of mouth ulcers.
