Canker sores, also known as aphthous ulcers, are painful, small lesions that form on the soft tissues of the mouth. They are a common, but often painful, condition that affects many people at some point in their lives. According to the American Academy of Oral Medicine, around 20% of the population suffers from canker sores. While canker sores are not contagious, they can be recurring and irritating. This article will explore natural remedies, over-the-counter products, dietary tips, and lifestyle changes that can help prevent and alleviate canker sores.

Natural Remedies for Canker Sores

Natural remedies such as honey, aloe vera, and baking soda can help soothe the pain and promote faster healing of canker sores. Honey has natural antibacterial properties and can help reduce inflammation. Aloe vera is known for its healing properties and can be applied topically to the sore to reduce inflammation and pain. Baking soda has antiseptic properties and can help neutralize acids in the mouth that can trigger canker sores. To use these remedies, mix honey or aloe vera gel with a small amount of water and apply to the sore with a cotton swab, or mix baking soda with water to form a paste and apply it to the sore. Rinse with warm water after a few minutes.

Over-the-Counter Topicals and Oral Rinses

Over-the-counter products such as oral rinses and topical creams can also be effective in relieving pain and promoting faster healing of canker sores. Topical options such as benzocaine and lidocaine can provide quick pain relief, while oral rinses containing hydrogen peroxide, chlorhexidine, or baking soda can reduce inflammation and promote healing. When choosing an OTC product, consider the severity of the canker sore and personal preference. Be aware that some products may have side effects or precautions when used, such as numbing the mouth or causing discoloration. Always follow the instructions on the product carefully.

Dietary Tips for Healing Canker Sores

Proper nutrition plays a critical role in overall health and healing from canker sores. Eating foods high in vitamins and minerals can be beneficial in promoting faster healing. Yogurt, leafy greens, and vitamin B12 are all adequate examples of foods with essential nutrients that can help to heal canker sores. Incorporating these foods into a healthy diet will help minimize the chances of more canker sores developing.

Lifestyle Changes for Canker Sore Prevention

Stress, acidic foods, and trauma can trigger canker sores in many people. Preventing canker sores may require several lifestyle changes. Implementing stress management techniques, such as meditation or relaxation exercises, can help to promote general well-being. Avoiding acidic foods like citrus fruits and vinegar as well as foods with sharp edges like chips will also help. Additionally, being careful with dental hygiene could prevent new canker sores from developing.

When to See a Doctor for Canker Sores

Although canker sores are generally not a cause of concern, those that are severe or persistent could indicate an underlying condition. Symptoms like high fever, extreme pain, or difficulty drinking may warrant medical attention. In such cases, visits to a dentist or physician are recommended. They may recommend prescription medication or laser therapy as treatment options. If children are experiencing canker sores and their symptoms persist, they should also see a doctor for adequate care.


Canker sores can be painful and uncomfortable. Fortunately, there are many natural remedies, over-the-counter products, dietary tips, and lifestyle changes that can help prevent and alleviate the symptoms of canker sores. Experimenting with a variety of strategies may be required to get the best results.
