12 min read

Canker sores, also known as aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums. They can be painful and usually last for 7 to 10 days. Canker sores are common and can affect anyone, but they are more common in women and people between the ages of 10 and 40.

Causes of Canker Sores

The exact cause of canker sores is unknown, but they may be triggered by a number of factors, including:

  • Stress
  • Hormonal changes
  • Certain foods, such as citrus fruits, tomatoes, and chocolate
  • Allergies to certain bacteria in the mouth
  • Toothpastes or mouth rinses containing sodium lauryl sulfate
  • Injury to the inside of the mouth, such as biting the inside of the cheek

Types of Canker Sores

Canker sores can be classified into three types:

  • Minor canker sores: These are the most common type of canker sores. They are small, round, and shallow, and usually heal without scarring within 7 to 10 days.
  • Major canker sores: These are larger and deeper than minor canker sores. They can take up to 6 weeks to heal and may leave a scar.
  • Herpetiform canker sores: These are clusters of many small canker sores that appear together. They are usually very painful and can take up to 3 weeks to heal.

Complications of Canker Sores

In some cases, canker sores can lead to complications, such as:

  • Infection
  • Scarring
  • Difficulty eating and drinking
  • Delayed healing

Symptoms

  • Painful sores inside the mouth

If you’re experiencing any of these symptoms, it’s important to see a doctor or dentist as soon as possible. They can help diagnose the cause of your canker sores and provide treatment to help reduce the pain and discomfort.

Causes

Genetics

Genetics may play a role in the development of canker sores. If you have a family history of canker sores, you may be more likely to develop them.

Stress

Stress can be a major factor in the development of canker sores. Stress can weaken the immune system, making it more difficult for the body to fight off infections and other irritants that can cause canker sores.

Hormonal Changes

Hormonal changes, such as those that occur during puberty, pregnancy, and menopause, can also increase the risk of canker sores.

Food Allergies

Food allergies can also be a cause of canker sores. Common food allergens that can trigger canker sores include dairy, wheat, eggs, and citrus fruits.

Vitamin Deficiencies

Vitamin deficiencies, such as a lack of vitamin B-12, folate, or iron, can also increase the risk of canker sores.

Injury

Injury to the mouth, such as from dental work or biting the inside of the cheek, can also cause canker sores.

Bacterial or Viral Infections

Bacterial or viral infections, such as the herpes simplex virus, can also cause canker sores.

Certain Medications

Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and chemotherapy drugs, can also increase the risk of canker sores.

Getting a Diagnosis

What to Expect During a Diagnosis

When you visit your doctor for a canker sore diagnosis, they will likely ask you about your symptoms and medical history. They may also perform a physical examination of your mouth. During this exam, they will look for any signs of canker sores, such as white or yellow patches, redness, or swelling. Your doctor may also take a sample of the sore to test for bacteria or viruses.

Other Tests

In some cases, your doctor may order additional tests to help diagnose your canker sores. These tests may include a blood test to check for any underlying medical conditions, such as anemia or vitamin deficiencies. Your doctor may also order an imaging test, such as an X-ray or CT scan, to look for any abnormalities in the mouth or throat.

Treatment Options

Once your doctor has diagnosed your canker sores, they will recommend a treatment plan. This may include over-the-counter medications, such as topical creams or gels, to reduce pain and inflammation. Your doctor may also recommend lifestyle changes, such as avoiding certain foods or reducing stress, to help prevent future outbreaks.

When to See a Doctor

If you have any signs or symptoms of canker sores, it is important to see your doctor for a proper diagnosis. Canker sores can be painful and uncomfortable, so it is important to get the right treatment as soon as possible. If your canker sores do not improve with treatment, or if they become worse, it is important to see your doctor right away.

Questions for Your Doctor

Symptoms

Describe your symptoms to your doctor. Be sure to include any pain, burning, or tingling sensations you may be experiencing. Also, let your doctor know if the canker sores are recurring or if they are new. This information can help your doctor determine the cause of the canker sores.

Treatment Options

Your doctor may recommend a variety of treatments for canker sores. These may include over-the-counter medications, prescription medications, or home remedies. Be sure to ask your doctor about the potential side effects of any medications they may prescribe.

Prevention

This may include avoiding certain foods, managing stress, and taking certain vitamins or supplements. Be sure to ask your doctor about any lifestyle changes you can make to reduce your risk of developing canker sores.

When to See a Doctor

If your canker sores are severe or do not respond to treatment, it is important to see a doctor. Your doctor may recommend further testing or treatment to help manage your symptoms. Additionally, if you experience any other symptoms, such as fever or difficulty swallowing, it is important to seek medical attention.

Discussing canker sores with your doctor can help you find the best treatment and prevention options for your individual needs. Be sure to provide your doctor with as much information as possible to ensure you receive the best care.

Treatment

Over-the-Counter Treatments

Over-the-counter treatments are the most common way to treat canker sores. These treatments typically contain ingredients such as benzocaine, which helps to numb the area and reduce pain. Other ingredients, such as menthol, can help to reduce inflammation and speed up the healing process. Many of these treatments come in the form of gels, creams, or ointments that can be applied directly to the sore.

Prescription Treatments

In some cases, a doctor may prescribe a stronger medication to help treat canker sores. These medications may contain corticosteroids, which can help reduce inflammation and pain. In some cases, a doctor may also prescribe an antibiotic to help prevent infection.

Home Remedies

There are also several home remedies that can be used to help treat canker sores. One of the most popular remedies is to rinse the mouth with a mixture of salt and water. This can help to reduce inflammation and pain. Other home remedies include applying a cold compress to the sore, or using a mixture of baking soda and water to create a paste that can be applied directly to the sore.

Preventative Measures

In addition to treating canker sores, it is important to take preventative measures to help reduce the risk of developing them in the first place. This includes avoiding foods that are known to trigger canker sores, such as citrus fruits and acidic foods.
