Canker Sores

Canker sores, also known as aphthous ulcers, are small, painful ulcerations that occur inside the mouth. They are not contagious and are believed to be caused by a combination of factors, including stress, genetics, hormonal changes, and an immune system reaction.

There are three main types of canker sores:

  1. Minor canker sores: These are the most common type and usually measure less than 1 centimeter in diameter. They usually heal on their own within 1-2 weeks.
  2. Major canker sores: These are larger and more severe than minor canker sores and can take several weeks to heal. They can also cause significant pain and make it difficult to eat and drink.
  3. Herpetiform canker sores: These are clusters of small canker sores that occur together and can cause significant discomfort.

Canker sores can be treated with over-the-counter pain relievers and topical creams. In severe cases, prescription medications may be necessary to manage pain and speed up the healing process.


Although the exact cause of canker sores is unknown, several factors have been identified that may contribute to their formation. Some of the main causes of canker sores include:

  1. Stress and trauma: Physical or emotional stress can trigger the formation of canker sores. Biting the inside of your cheek or having dental work done can also cause canker sores.
  2. Hormonal changes: Hormonal changes, such as those that occur during menstruation, can lead to the formation of canker sores.
  3. Foods: Certain foods, such as chocolate, coffee, and acidic fruits, can irritate the mouth and trigger canker sores.
  4. Allergies: Allergies to certain foods, such as gluten, can cause canker sores.
  5. Nutritional deficiencies: A lack of certain vitamins and minerals, such as iron, folic acid, and vitamin B-12, can increase the risk of canker sores.
  6. Infections: Certain infections, such as the herpes simplex virus, can cause canker sores.
  7. Immune system disorders: Chronic immune system disorders, such as Crohn’s disease or HIV/AIDS, can increase the risk of canker sores.

In conclusion, canker sores can be caused by a variety of factors, including stress, hormonal changes, food allergies, nutritional deficiencies, infections, and immune system disorders. It is important to seek medical treatment if canker sores become frequent or persistent.


The main symptoms of canker sores include:

  1. Pain: The sores are usually painful and can make eating and speaking difficult.
  2. Appearance: Canker sores are usually round or oval in shape, with a red border and a white or yellow center. They can range in size from a tiny dot to several centimeters in diameter.
  3. Tingling or burning sensation: Before the appearance of a canker sore, many people experience a tingling or burning sensation in the area where the sore will appear.
  4. Swelling: Canker sores can cause swelling and redness in the surrounding area.
  5. A number of sores: Canker sores can appear one at a time or in clusters.
  6. Duration: Canker sores usually heal within 10-14 days without leaving a scar.
  7. Recurrence: Some people experience recurrent outbreaks of canker sores, which can be a sign of an underlying health condition.

If you are experiencing any of these symptoms, it is important to consult a healthcare provider to determine the cause and receive proper treatment.


The main diagnosis of canker sores involves the following steps:

  1. Physical examination: A dentist or doctor will visually inspect the canker sores to determine their size, location, and number.
  2. Medical history: The doctor will ask about any recent stress, injury, or illness that may have triggered the canker sores.
  3. Tests: In some cases, additional tests may be needed to rule out other underlying conditions. These may include:
  • Blood tests: To check for anemia or other underlying health conditions
  • Biopsy: A small sample of tissue may be taken for laboratory analysis to rule out other conditions such as oral cancer
  • Culture: A swab of the canker sore may be taken to identify any infections

The results of these tests will help the doctor determine the underlying cause of the canker sores and develop a treatment plan. In most cases, canker sores are diagnosed based on physical examination and medical history.


The main treatment of canker sores includes:

  1. Pain relief: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help reduce pain and discomfort.
  2. Topical creams: Anesthetic creams, such as benzocaine, can also be applied directly to the sore to relieve pain.
  3. Antiseptic mouthwash: Rinsing the mouth with an antiseptic mouthwash can help soothe the sore and reduce the risk of infection.
  4. Vitamin supplements: Taking vitamin B-12, folic acid, and iron supplements may help improve the healing process and prevent future outbreaks.
  5. Avoiding irritants: Avoiding spicy or acidic foods, and using a soft-bristled toothbrush can help reduce irritation to the sore.
  6. Prescription medication: If the canker sores are severe or persistent, a doctor may prescribe a topical steroid, an antiviral medication, or an immunomodulator.

It is important to seek medical advice if the canker sores persist for more than two weeks or if they are accompanied by other symptoms such as fever, swelling, or difficulty swallowing.
