Canker sores, also known as aphthous ulcers, are small, shallow lesions that develop on the soft tissues in the mouth or at the base of the gums. They usually have a white or yellow center and a red border and can be extremely painful. Canker sores occur singly or in clusters on the inside surfaces of the cheeks or lips, on or under the tongue, at the base of the gums, or on the soft palate. They are not contagious like cold sores and typically go away on their own within a week or two. However, larger or more painful canker sores may require medical attention.

Types of Canker Sores
There are three main types of canker sores: minor, major, and herpetiform. Understanding the characteristics of each type can help identify and manage these troublesome mouth ulcers.
Minor Canker Sores
Minor canker sores are the most common type, accounting for about 80% of cases. These sores are usually small, oval-shaped, and have a red edge. While they can be painful, they typically heal without scarring within one to two weeks.
Major Canker Sores
Less common than minor canker sores, major canker sores are larger and deeper. They are usually round with defined borders, although they may have irregular edges when very large. Major canker sores can be extremely painful and may take up to six weeks to heal. In some cases, they can leave extensive scarring.
Herpetiform Canker Sores
Herpetiform canker sores are the least common type and often develop later in life. They are characterized by pinpoint-size sores that occur in clusters of 10 to 100, which can merge into one large ulcer. These sores have irregular edges and typically heal without scarring within one to two weeks.
While canker sores can be uncomfortable and frustrating, knowing the types can help you understand and manage these painful mouth ulcers.
Causes of Canker Sores
The exact cause of canker sores is still unclear, but researchers believe that a combination of factors contributes to their development. These factors include:
- A minor injury to the mouth, such as from dental work or accidental cheek biting
- Toothpastes and mouth rinses containing sodium lauryl sulfate
- Food sensitivities to chocolate, coffee, strawberries, eggs, nuts, cheese, and spicy or acidic foods
- Deficiencies in vitamin B-12, zinc, folate (folic acid), or iron
- An allergic response to certain mouth bacteria
- An infection with Helicobacter pylori
- Hormonal shifts during menstruation
- Emotional stress
- Underlying conditions such as celiac disease, inflammatory bowel diseases, Behcet’s disease, and immune system disorders like HIV/AIDS
While these factors are believed to play a role in the development of canker sores, it’s important to note that not everyone who experiences these triggers will develop canker sores. The exact interplay between these factors and an individual’s susceptibility to canker sores is still being studied.
While the exact cause of canker sores is not fully understood, research suggests that factors such as minor mouth injuries, toothpastes with sodium lauryl sulfate, food sensitivities, nutrient deficiencies, and underlying conditions can contribute to their development.
In addition to these potential causes, it’s worth noting that emotional stress and hormonal shifts can also increase the likelihood of developing canker sores. The body’s response to stress and hormonal fluctuations can sometimes manifest as canker sores. Although the exact mechanism is not fully understood, it is believed to involve changes in the immune system and inflammation.
It’s important to remember that canker sores are highly variable and can be influenced by multiple factors. Identifying and avoiding triggers that may exacerbate canker sores can help individuals reduce their frequency and duration. If you are experiencing frequent or severe canker sores, it is recommended to consult with a healthcare professional for further evaluation and management.
Symptoms of Canker Sores
Canker sores are a common oral condition that can cause significant discomfort. Recognizing the symptoms of canker sores is essential for early detection and proper management.
Canker sores typically appear as round or oval-shaped sores in the mouth. They have a white or yellow center and a red border, making them easily distinguishable from other oral lesions. These sores can form on the inside surfaces of the cheeks or lips, under the tongue, at the base of the gums, or on the soft palate.
Prior to the appearance of canker sores, individuals may experience a tingling or burning sensation in the affected area. This sensation usually occurs a day or two before the sores become visible. It is important to note that the size and shape of canker sores may vary depending on the type. Minor canker sores are small and oval-shaped with a red edge, while major canker sores are larger and round with defined borders. Herpetiform canker sores are pinpoint size and often occur in clusters.
Overall, being aware of the characteristic features of canker sores, such as their round or oval shape, white or yellow center, red border, and associated tingling or burning sensation, can help individuals identify and manage these uncomfortable oral sores.
| Type of Canker Sores | Description |
|---|---|
| Minor Canker Sores | Small, oval-shaped sores with a red edge |
| Major Canker Sores | Larger and deeper than minor canker sores, usually round with defined borders |
| Herpetiform Canker Sores | Pinpoint size, often occurring in clusters of 10 to 100 sores, with irregular edges |
When to See a Doctor for Canker Sores
If you experience unusually large canker sores, recurring or frequent outbreaks, persistent sores, sores that extend into the lips, uncontrolled pain, difficulty eating or drinking, or a high fever along with canker sores, it may be time to seek medical attention. While most canker sores go away on their own within a week or two, these symptoms could be indicative of a more serious underlying condition that requires professional evaluation.
Unusually large canker sores that are significantly larger than the typical size may require medical attention. These larger sores can be more painful and may take longer to heal. Recurring or frequent outbreaks of canker sores, where new sores appear before old ones have healed, could be a sign of an underlying issue that needs to be addressed.
If you have persistent sores that last for more than two weeks, it is recommended to see a doctor. Sores that extend into the lips themselves can be particularly concerning and should be examined by a healthcare professional. Additionally, if you are experiencing uncontrolled pain or difficulty eating and drinking due to canker sores, medical intervention may be necessary to provide relief.
Finally, if you develop a high fever along with canker sores, it is essential to seek medical attention. A fever could indicate an infection or other systemic issue that requires treatment. By consulting a doctor, you can ensure appropriate evaluation and management of your canker sores based on the severity of your symptoms.
Prevention of Canker Sores
Preventing canker sores can help reduce their frequency and minimize discomfort. By following a few simple steps, you can significantly decrease the likelihood of developing these painful mouth ulcers.
Avoiding Irritants
Avoiding foods and substances that irritate your mouth is crucial in preventing canker sores. Stay away from nuts, chips, pretzels, spices, salty foods, and acidic fruits, as they can trigger or worsen canker sores. Opt for a diet that consists of plenty of fruits, vegetables, and whole grains to ensure you’re getting the necessary nutrients to maintain oral health.
Practicing Good Oral Hygiene
Maintaining good oral hygiene is essential in preventing canker sores. Brush your teeth after meals with a soft-bristled toothbrush and use a toothpaste that does not contain sodium lauryl sulfate, as this ingredient can irritate the mouth. Additionally, floss daily to remove food particles and bacteria from between your teeth and rinse your mouth with a mild mouthwash or saltwater solution to promote good oral health.
Protecting the Mouth
If you have braces or dental appliances, be mindful of any sharp edges that could potentially injure your mouth. Apply orthodontic wax to cover these sharp edges and prevent canker sores from developing. It’s also important to avoid any accidental cheek biting or trauma to the mouth, as these can contribute to the formation of canker sores.
Reducing Stress
Reducing stress is beneficial for overall health and well-being, including the prevention of canker sores. Engage in stress-reduction techniques such as meditation, deep breathing exercises, or guided imagery to help manage stress levels. Finding healthy outlets for stress can contribute to a healthier mouth and reduce the likelihood of canker sores.
The prevention of canker sores involves avoiding irritants, practicing good oral hygiene, protecting the mouth, and reducing stress. By implementing these strategies, you can minimize the occurrence of canker sores and maintain a healthy mouth.
Treatment Options for Canker Sores
When it comes to treating canker sores, there are several options available to help relieve pain and promote healing. These treatments range from over-the-counter gels and natural remedies to prescription medications and addressing underlying conditions.
One of the most common treatment options for canker sores is the use of over-the-counter gels or ointments. These products often contain numbing agents that can help alleviate the pain associated with canker sores. Simply apply the gel directly to the sore as directed by the product’s instructions.
Salt water rinses can also be an effective way to treat canker sores. Mixing a teaspoon of salt in a cup of warm water and swishing the solution around in your mouth can help reduce inflammation and promote healing. Repeat this process several times a day for best results.
In addition to over-the-counter gels and salt water rinses, there are also various natural remedies that can be used to treat canker sores. For example, hydrogen peroxide and milk of magnesia can be applied directly to the sore to help reduce pain and promote healing. These natural remedies can often be found in your local grocery or pharmacy.
In more severe cases, prescription medications may be necessary to treat canker sores. These medications can include corticosteroids or chlorhexidine mouthwash, which can help reduce inflammation and prevent infection. It’s important to consult with a healthcare professional to determine the best course of treatment for your specific situation.
Lastly, addressing any underlying conditions that may be contributing to the development of canker sores is also an important part of treatment. If canker sores are a recurring issue, it may be helpful to undergo further testing or evaluation to identify and treat any underlying conditions or deficiencies that may be contributing to their occurrence.
Differences between Canker Sores and Fever Blisters
Canker sores and fever blisters (cold sores) are two different conditions with distinct characteristics. While canker sores occur inside the mouth, specifically on the soft tissues, fever blisters form on the outside of the mouth around the lips.
Canker sores are typically round or oval with a white or yellow center and a red border, while fever blisters are clusters of small fluid-filled blisters.
Canker sores have various triggers, such as minor injuries, toothpastes with sodium lauryl sulfate, and nutrient deficiencies, while fever blisters are caused by an infection with the herpes simplex virus.
Canker sores are not contagious, but fever blisters are highly contagious. The treatment options for fever blisters include antiviral medications, while canker sores can be managed with over-the-counter gels and natural remedies.
Table: Differences between Canker Sores and Fever Blisters
| Characteristics | Canker Sores | Fever Blisters |
|---|---|---|
