It will cover everything from identifying the signs and symptoms of canker sores, to the effectiveness of home remedies, over-the-counter solutions, and prescription treatments. Furthermore, preventative strategies aimed at minimizing the risk of future outbreaks will be discussed. By providing a comprehensive overview of canker sore relief and prevention, this article aims to equip readers with the knowledge to better manage this uncomfortable condition.
What Are Canker Sores?
Canker sores, also known as aphthous ulcers or recurring aphthous stomatitis, are small, shallow lesions that develop on the soft tissues inside the mouth. These painful sores can appear on the tongue, gums, roof of the mouth, inside of the lips, or under the tongue. Unlike cold sores, canker sores are not contagious and do not occur on the surface of the lips.
Approximately 20% of people will experience canker sores at some point in their life, although the exact cause remains unknown. Factors such as stress, injury to the inside of the mouth, acidic foods, nonsteroidal anti-inflammatory drugs (NSAIDs), and dental appliances like braces or ill-fitting dentures may trigger the development of these ulcers. Additionally, complex canker sores can be associated with immune system conditions, including lupus, Behcet’s disease, celiac disease, ulcerative colitis, Crohn’s disease, and AIDS.

Types of Canker Sores
There are three main types of canker sores:
- Simple or Minor Canker Sores: These are the most common type, accounting for around 80% of cases. They are typically small (less than 1 millimeter) but may grow to 1/2 inch in diameter. Simple canker sores usually heal within two weeks without leaving scars.
- Complex or Major Canker Sores: These sores are less common and larger than simple canker sores, often exceeding 1/2 inch in diameter. They can last for up to six weeks and may leave scars upon healing. Complex canker sores are more likely to occur in people with compromised immune systems.
- Herpetiform Canker Sores: Despite their name, these sores are not caused by the herpes virus. Herpetiform canker sores appear as clusters of several tiny lesions that often converge to form one large sore. They can last from one week to one month and tend to affect younger adults.
While canker sores can be uncomfortable and make eating and talking difficult, most cases resolve on their own within a few weeks. However, if you experience unusually large, painful, or persistent canker sores that do not heal after 14 days, it is advisable to consult a healthcare provider for proper diagnosis and treatment.
Symptoms and Diagnosis
Canker sores, also known as aphthous ulcers, are characterized by painful white or yellow sores that develop inside the mouth. These sores can appear on the tongue, gums, roof of the mouth, or inside the cheeks and lips. Symptoms may include a burning or tingling sensation prior to the appearance of the sore, followed by a round, white or yellow lesion with a red border.
Recognizing Symptoms
There are three main types of canker sores:
- Minor canker sores: These are the most common, measuring less than 1 centimeter in diameter. They typically heal within one to two weeks without scarring.
- Major canker sores: These are larger and deeper than minor canker sores, often exceeding 1 centimeter in diameter. They can be extremely painful and may take up to six weeks to heal, potentially leaving scars.
- Herpetiform canker sores: Despite their name, these sores are not caused by the herpes virus. They appear as clusters of multiple tiny lesions that may merge to form larger ulcers. Herpetiform canker sores usually heal within one to two weeks without scarring.
Distinguishing from Cold Sores
It is important to differentiate canker sores from cold sores, as they have different causes and treatments. Cold sores, also known as fever blisters, are caused by the herpes simplex virus and appear as fluid-filled blisters on or around the lips. Unlike canker sores, cold sores are contagious and can spread through close personal contact.
When to Seek Professional Help
While most canker sores resolve on their own within a few weeks, it is advisable to consult a healthcare provider if you experience:
- Unusually large canker sores
- Sores that persist for more than two weeks
- Frequent recurrences of canker sores
- Severe pain that interferes with eating or drinking
- High fever accompanying the canker sores
Your doctor or dentist can diagnose canker sores through a visual examination. In some cases, they may recommend tests to rule out underlying health conditions, especially if the sores are severe or recurrent. These tests may include blood work to check for nutritional deficiencies, food allergies, or immune disorders.
By recognizing the symptoms, distinguishing canker sores from cold sores, and knowing when to seek professional help, individuals can effectively manage and treat these painful oral lesions.
Home Remedies
While most canker sores resolve on their own within a few weeks, several home remedies can help alleviate pain and speed up the healing process. These natural treatments are readily available and easy to implement.
Salt Water Rinse
A simple salt water rinse can be an effective way to treat canker sores. Salt helps to reduce inflammation by restoring the pH balance in the mouth, creating an environment that makes it harder for bacteria to thrive. To make a salt water rinse, follow these steps:
- Mix one teaspoon of salt in a cup of warm water until fully dissolved.
- Take a sip of the solution, swish it around in your mouth for about 30 seconds, focusing on the affected area, and then spit it out.
- Repeat this process several times a day until the canker sore heals.
It is important to note that while a salt water rinse can provide relief, putting salt directly on the canker sore can worsen the pain and irritation.
Baking Soda Rinse
Similar to salt, baking soda can help neutralize acid in the mouth, reducing pain and promoting healing. Baking soda also has antibacterial properties that can help prevent infection. To make a baking soda rinse:
- Mix one teaspoon of baking soda with a cup of warm water until it dissolves.
- Swish the solution in your mouth for about 30 seconds, then spit it out.
- Repeat this process several times a day.
Alternatively, you can make a paste by mixing a small amount of baking soda with water and applying it directly to the canker sore. Leave the paste on for a few minutes before rinsing your mouth with water.
Honey Application
Honey has natural antibacterial and anti-inflammatory properties that can help reduce pain and promote healing of canker sores. To use honey as a treatment:
- Apply a small amount of honey directly to the canker sore using a clean finger or a cotton swab.
- Leave the honey on the sore for several minutes before rinsing your mouth with warm water.
- Repeat this process several times a day.
For best results, use raw, unprocessed honey, such as Manuka honey, which has been shown to have potent healing properties.
In addition to these remedies, it is important to maintain good oral hygiene and avoid irritating the canker sore further. Use a soft-bristled toothbrush and brush gently to prevent aggravating the sore. Avoiding acidic, spicy, or abrasive foods can also help reduce discomfort and promote healing.
Over-the-Counter Solutions
When home remedies fail to provide adequate relief from canker sore symptoms, over-the-counter treatments can be an effective alternative. These products are readily available without a prescription and offer a range of options to manage pain, promote healing, and prevent infection.
FDA-Approved Treatments
One notable FDA-approved treatment for canker sores is Kourzeq™, launched by MidAmerica Pharmaceuticals. While the exact mechanism of topical steroids is unclear, they are thought to reduce inflammation by inducing phospholipase A2 inhibitory proteins. Kourzeq is supplied in tubes containing 5g of dental paste and is available exclusively via telehealth through a partnership with BeyondMD.
Pain Relief Options
Over-the-counter pain relievers and oral anesthetic gels can help manage the discomfort associated with canker sores. Products containing benzocaine, a topical anesthetic, work by numbing the nerve endings in the affected area, providing temporary pain relief. These treatments are available in various forms, such as patches that can be placed directly over the sore, topical gels and ointments for application to multiple sores, and lozenges that melt in the mouth to distribute medicine over a wider area.

Healing Aids
In addition to pain relief, some over-the-counter products aim to speed up the healing process of canker sores. Mouthwashes containing ingredients like saltwater, alcohol-free commercial mouthwash, or a mixture of milk of magnesia and liquid allergy medicine can help keep the mouth clean and prevent bacterial growth that may worsen the sore. Regularly rinsing the mouth with these solutions can promote faster healing.
It is important to follow the instructions carefully when using any over-the-counter canker sore medicine to ensure the best possible results. Most products are intended for use only for a certain number of days, and if symptoms persist beyond that time, it is advisable to consult a medical professional for further guidance.
Prescription Treatments
For severe or persistent canker sores, prescription treatments may be necessary to alleviate pain and promote healing. These treatments often target the underlying cause of the canker sore, such as bacterial infections or inflammation. A healthcare professional can determine the most appropriate prescription treatment based on the individual’s specific needs and medical history.
Antibiotic Treatments
If a bacterial infection is suspected to be the cause of the canker sore, a dentist or healthcare provider may prescribe an antibiotic. However, prolonged use of antibiotics can lead to complications such as oral thrush or candidiasis, so it is essential to follow the prescribed duration of treatment.
Corticosteroid Ointments
Topical corticosteroids can be prescribed to reduce inflammation and promote healing of canker sores. These medications are available in various forms, including gels, pastes, and lozenges. Some common corticosteroids used for treating canker sores include:
- Hydrocortisone hemisuccinate (available as pellets or lozenges)
- Beclomethasone (available as mouthwash and inhaler sprays)
Corticosteroids should be used as directed by a healthcare professional, as prolonged or excessive use can lead to side effects such as oral thrush or adrenal suppression.
Prescription Mouthwashes
Prescription mouthwashes containing various medications can be effective in managing canker sore symptoms. One such example is magic mouthwash, also known as miracle mouthwash or Duke’s magic mouthwash. These mouthwashes typically contain a combination of ingredients, such as:
- An antibiotic to kill bacteria around the sore
- An antifungal to prevent fungal growth
- An antihistamine or anticholinergic to reduce pain
- A local anesthetic for pain relief
- An antacid to help spread the other ingredients throughout the mouth
The specific ingredients and concentrations may vary depending on the individual’s needs and the prescribing healthcare professional. It is essential to use prescription mouthwashes as directed and to avoid eating or drinking for at least 30 minutes after use to allow the medication to take effect.
In some cases, a healthcare professional may recommend a combination of prescription treatments to effectively manage canker sores. It is crucial to follow the prescribed treatment plan and to report any adverse side effects or persistent symptoms to the prescribing healthcare professional.
Preventing Canker Sores
While there is no guaranteed way to prevent canker sores, several strategies can help reduce their frequency and severity. These include nutritional supplements, avoiding trigger foods, and maintaining good oral hygiene practices.
Nutritional Supplements
Certain nutritional deficiencies have been linked to the development of canker sores. Supplementing your diet with the following nutrients may help prevent or reduce the occurrence of these painful ulcers:
- Vitamin B12: Studies have shown that a deficiency in vitamin B12 can contribute to canker sores. Ensuring adequate intake of this vitamin through diet or supplements may help prevent their development.
- Zinc: Zinc plays a crucial role in wound healing and immune function. Supplementing with zinc may help reduce the frequency and duration of canker sores.
- Folic acid: Low levels of folic acid have been associated with an increased risk of canker sores. Incorporating folic acid-rich foods or taking supplements can help maintain healthy levels and potentially prevent sores.
- Iron: Iron deficiency anemia has been linked to the occurrence of canker sores. If you are prone to these ulcers, it may be beneficial to have your iron levels checked and address any deficiencies through diet or supplementation.
Avoiding Trigger Foods
Certain foods can irritate the sensitive tissues in your mouth, potentially triggering the development of canker sores. Common trigger foods include:
- Acidic fruits and vegetables, such as lemons, oranges, pineapples, and tomatoes
- Spicy or hot foods
- Foods with sharp edges, like chips or pretzels
- Highly processed foods with artificial additives
By identifying and avoiding your personal trigger foods, you may be able to reduce the frequency of canker sore outbreaks.

Oral Hygiene Practices
Maintaining good oral hygiene is essential for preventing canker sores and promoting overall oral health. Consider the following practices:
- Use a soft-bristled toothbrush: Soft bristles are gentler on your gums and less likely to cause irritation that could lead to canker sores.
- Brush and floss regularly: Removing plaque and food particles through regular brushing and flossing can help prevent bacterial growth and reduce inflammation in your mouth.
- Avoid harsh oral products: Some toothpastes and mouthwashes contain sodium lauryl sulfate (SLS), which can irritate the delicate tissues in your mouth. Opting for SLS-free products may help reduce the risk of canker sores.
- Replace your toothbrush: If you have recently had a canker sore, replace your toothbrush to prevent reinfection from bacteria that may linger on the bristles.
By incorporating these preventative measures into your daily routine, you may be able to reduce the occurrence of canker sores and maintain a healthier, more comfortable mouth.
