What Are Canker Sores?
Canker sores are small, round, or oval ulcers with a white or yellow center and a red border. They typically occur inside the mouth, on the tongue, inside cheeks, lips, or at the base of the gums. According to the Cleveland Clinic, the exact cause of canker sores is unclear, but several factors may contribute to their development.
Symptoms of Canker Sores
The most common symptoms of canker sores include:
- A painful sore or sores inside your mouth: on the tongue, soft palate, or inside your cheeks.
- A tingling or burning sensation before the sores appear.
- Sores in your mouth that are round, white, or gray, with a red edge or border.
Causes and Contributing Factors
Several factors can contribute to the development of canker sores, including:
- Minor mouth injury from dental work, overzealous brushing, sports mishaps, or an accidental cheek bite.
- Toothpastes and mouth rinses containing sodium lauryl sulfate.
- Food sensitivities, particularly to chocolate, coffee, strawberries, eggs, nuts, cheese, and spicy or acidic foods.
- A diet lacking in vitamin B-12, zinc, folate (folic acid), or iron.
- An allergic response to certain bacteria in your mouth.
- Hormonal shifts during menstruation.
- Emotional stress.
- Celiac disease, inflammatory bowel diseases, Behcet's disease, and HIV/AIDS, which cause immune system weakening.
WebMD and MedlinePlus note that canker sores are not caused by viruses or bacteria and are not contagious.
Prevention
While it's not always possible to prevent canker sores, some steps can help reduce their frequency:
- Avoid foods that irritate your mouth, including citrus fruits, acidic vegetables, and spicy foods.
- Chew slowly to avoid accidental cheek bites.
- Use a soft-bristled toothbrush and brush gently.
- Avoid toothpaste and mouth rinses containing sodium lauryl sulfate.
- Manage stress through relaxation and stress-reduction techniques.
- Maintain good oral hygiene.
- Ensure a well-balanced diet with adequate nutrition.
Taking these preventative measures can help reduce the risk of developing canker sores. If you frequently experience painful canker sores, it might be worthwhile to discuss this with a healthcare provider, who can recommend further steps for management and prevention.
Diagnosis and Testing
Canker sores are usually diagnosed based on their appearance. A healthcare provider will look at the sores and review your medical history. According to the American Academy of Oral Medicine, in most cases, tests are not needed. However, if canker sores are unusually large, recurrent, or persistently painful, additional tests may be conducted to rule out other conditions.
Complications
Complications from canker sores are rare but can include:
- A secondary bacterial infection.
- Cellulitis, especially if the sores are large.
- Scarring in severe cases.
Treatment
The National Institute of Dental and Craniofacial Research highlights that treatment for canker sores focuses on relieving pain and speeding up healing. Options include:
- Over-the-counter topical products (creams, gels, or liquids).
- Mouth rinses with a corticosteroid or antibacterial agent.
- Oral medications when sores are severe.
- Cautery of sores in extreme cases.
At-Home Remedies
Simple home remedies can alleviate discomfort:
- Rinsing the mouth with a solution of saltwater or baking soda.
- Applying a damp tea bag to the sore for a few minutes.
- Avoiding spicy, acidic, or hot foods that can irritate the sores.
