What Are Canker Sores?
Aphthous ulcers, also called canker sores, are small, shallow lesions in the mouth. Usually, white or yellow in the center with a red border. Cold sores, also known as herpes simplex virus, are generally different from canker sores (aphthous ulcers) and appear away from the mouth, often around the lips. Canker sores are not contagious and they are very painful, particularly when eating foods that are acidic, spicy, or hot.

While the exact cause of canker sores remains unclear, several factors may contribute to their development:
- Injury or Trauma: This can also be caused by accidentally biting the inside of your cheek, brushing too hard, or a dental procedure.
- Stress: Removal of canker sores can occur due to emotional stress and anxiety causing the weakening of the immune system.
- Hormonal Changes: Canker sores can be triggered by hormonal changes during menstruation or pregnancy.
- Nutritional Deficiencies: Mouth ulcers can occur due to a lack of essential nutrients, like vitamin B12, folate, zinc, or iron.
- Food Sensitivities: Canker sores can be triggered or irritated by acidic foods (such as citrus fruit and tomatoes) and spicy foods.
- Underlying Health Conditions: Canker sores can be more likely in people who have conditions such as celiac disease, Crohn’s disease, or HIV.
Canker Sore Symptoms
The most prominent sign of a canker sore is a painful ulceration in the mouth. Other common symptoms include:
- Feeling burning or tingling just before the ulcer develops.

Most canker sores go away in 7 to 10 days and don’t require medical treatment. However, it may take some people longer depending on how painful or large the sores are. When canker sores are frequent, then it’s time to visit one’s doctor to find out if there are any conditions (and underlying reasons) that might be causing them to develop.
Effective Canker Sore Treatments
There’s no cure for canker sores, but it is possible to reduce pain, help heal cankers more quickly, and help prevent infection by using certain treatments. Here are the most common and effective remedies for canker sore treatment:

- Antiseptic Mouth Rinses: If you have mouthwashes such as with hydrogen peroxide or alcohol in them, you can clean the affected area and help to prevent infection. Listerine mouthwash, for example, contains an antiseptic that may be soothing as well as disinfecting the sore.
- Corticosteroid Ointments: Severe cases may be treated using prescription ointments made up of corticosteroids, e.g. triamcinolone acetonide, to reduce inflammation and help heal the infection.
2. Saltwater Rinse

Make the rinse by putting 1 teaspoon of salt into a glass of warm water. Swish the solution around in your mouth for 30 seconds and spit it out. Do this at least several times a day, especially after meals.

4. Aloe Vera Gel
Aloe vera is famous for its soothing and anti-inflammatory properties. Putting some aloe vera gel directly onto the canker sore will help reduce pain and speed up the healing.

Canker sores can be soothed and also help the healing process if honey helps as a natural antibacterial agent. Honey rubbed directly on the sore helps lessen irritation and prevents the area from drying out. Besides that, honey is also anti-inflammatory and can help in pain relief.
6. Coconut Oil

Slicking coconut oil back and forth in your mouth (often called oil pulling) for several minutes can ward off bacteria and dull the ghostly white fire of a painful canker sore. You can also apply a small amount of coconut oil directly to the sore to alleviate pain or inflammation.
7. Avoid Irritating Foods
