Oral Canker Sores: Causes and Remedies for White Spots - Otolaryngology

Oral canker sores, also known as aphthous ulcers, are painful lesions that can develop inside the mouth, including on the tongue, gums, and inner cheeks. They typically appear as small, round, white or grayish spots with a red halo, and can be quite uncomfortable, especially when eating or speaking. The exact cause of canker sores is not fully understood, but several factors may contribute to their development.

One of the primary triggers for canker sores is stress. Emotional stress can lead to a weakened immune response, making the body more susceptible to various ailments, including oral ulcers. In your case, you mentioned experiencing insufficient sleep and increased stress levels, which could indeed be contributing factors. Sleep deprivation can affect your overall health and immune function, potentially leading to the development of canker sores.

Another common cause of canker sores is nutritional deficiencies. Deficiencies in vitamins and minerals, particularly vitamin B12, folic acid, iron, and zinc, can increase the likelihood of developing these sores. If your diet has been lacking in these essential nutrients, it might be worth considering dietary adjustments or consulting a healthcare professional for advice on supplementation.

Additionally, certain food sensitivities or allergies can trigger canker sores. Foods that are acidic or spicy, such as citrus fruits, tomatoes, and hot peppers, can irritate the mucous membranes in the mouth and may lead to the formation of sores. If you have recently consumed more of these types of foods, it could be a contributing factor.

Hormonal changes, particularly in women, can also play a role in the occurrence of canker sores. Some women report an increase in the frequency of these sores during their menstrual cycle due to hormonal fluctuations.

In terms of remedies, there are several approaches you can take to alleviate the discomfort associated with canker sores. Over-the-counter topical treatments, such as benzocaine or hydrogen peroxide, can help numb the area and promote healing. Additionally, rinsing your mouth with a saltwater solution can help reduce inflammation and promote healing. It’s important to avoid irritating foods and beverages, such as spicy or acidic items, until the sores have healed.

If your canker sores persist for more than two weeks, or if you experience severe pain, difficulty swallowing, or a high fever, it is advisable to seek medical attention. A healthcare provider can evaluate your condition and may recommend prescription medications or further investigations to rule out underlying health issues.

In summary, your recent experience with canker sores may be linked to stress, lack of sleep, dietary factors, or other triggers. By addressing these potential causes and implementing some home remedies, you can help manage the symptoms and promote healing. If the sores do not improve or worsen, it is essential to consult a healthcare professional for further evaluation and treatment options.
