Canker sores, also called aphthous ulcers, can be painful and interfere with your daily activities. Although they usually heal by themselves, there are several over-the-counter (OTC) treatments that can help to reduce discomfort and speed up recovery. This guide explores the top OTC treatments for canker sores, their benefits, how they work, and how to select the right option for you. Whether you’re dealing with one sore or frequent outbreaks, this post will help you make an informed choice and find relief fast.
Understanding Canker Sores:
Canker sores are small, painful ulcers that show up inside the mouth, usually on soft tissues like the tongue, inner cheeks, or the roof of the mouth. Unlike cold sores, which are caused by the herpes simplex virus, canker sores aren’t contagious. They typically have a round or oval shape with a white or gray center and a red ring around it.
Causes of Canker Sores:
The exact cause of canker sores isn’t fully understood, but several things might contribute to their development:
- Stress: Emotional stress or anxiety can trigger or worsen canker sores.
- Dietary Factors: Certain foods, especially acidic or spicy ones, can irritate the mouth and cause canker sores.
- Nutritional Deficiencies: Lack of important nutrients such as vitamin B12, folic acid, and iron may be linked to canker sores.
- Hormonal Changes: Some women get canker sores during hormonal changes, like menstruation.
- Genetics: A family history of canker sores may make you more likely to get them.
- Underlying Health Conditions: Conditions like Crohn’s disease or Behçet’s disease can cause recurring canker sores.
Symptoms and Diagnosis:
Canker sores usually show up as:
- Pain and Sensitivity: They’re often painful, particularly when eating or talking.
- Lesion Appearance: The sores are usually round or oval, with a white or gray center and a red border.
- Size and Duration: They can vary from a few millimeters to a centimeter in size and usually heal in 1-2 weeks without treatment.
Diagnosis is typically based on the appearance of the sores and your medical history. If canker sores are unusually large, persistent, or come with other symptoms, it’s a good idea to see a healthcare provider.
