What Causes Canker Sores in Children and How Can They Be Treated?

Canker sores are a common condition that affects many children. They are small, painful ulcers that develop inside the mouth, on the tongue, and on the lips. Although canker sores can be quite uncomfortable, they are not contagious, and they usually go away on their own within a few days to a couple of weeks. 

In this article, we will discuss the causes, symptoms, and treatments for canker sores in kids.

CAUSES OF CANKER SORES IN KIDS

The exact cause of canker sores is still unknown. However, there are several triggers that can lead to the development of these sores. Some of these triggers include stress, injury, a weak immune system, food allergies, and nutritional deficiencies. When a child is under stress or has an injury in the mouth, it can trigger the development of canker sores. 

Additionally, children who have a weak immune system, such as those with HIV or undergoing chemotherapy, are more susceptible to canker sores. Certain foods, such as citrus fruits, chocolate, and nuts, can also trigger the development of canker sores in some children.

COMMON CAUSES:

  • Stress or anxiety

  • Injury or trauma to the mouth, such as biting the inside of the cheek or lip

  • Weak immune system

  • Hormonal changes, such as during puberty

  • Nutritional deficiencies, including deficiencies in vitamin B12, folate, or iron

  • Food allergies or sensitivities to certain foods, such as citrus fruits, chocolate, or nuts

  • Mouthwash or toothpaste containing sodium lauryl sulfate

  • Certain medical conditions, such as celiac disease or inflammatory bowel disease

  • Genetic predisposition

  • Hormonal changes during menstrual cycles in adolescent girls

    SYMPTOMS OF CANKER SORES IN KIDS

    The symptoms of canker sores in kids can vary in severity. They often begin with a burning or tingling sensation in the affected area, followed by the development of a red or white spot that is surrounded by a red halo. The sore can be quite painful, especially when eating or drinking. In severe cases, a child may experience fever, swollen lymph nodes, or difficulty swallowing.

    COMMON SYMPTOMS:

    • Small, round or oval-shaped sores that develop inside the mouth, on the tongue, or on the lips

    • A burning or tingling sensation in the affected area prior to the development of the sore

    • Redness or inflammation around the sore

    • White or gray coloration in the center of the sore with a red border

    • Pain or discomfort when eating, drinking, or speaking

    • Swollen lymph nodes in the neck or under the jaw

    • Fever or other flu-like symptoms in severe cases

    • Difficulty swallowing or talking in severe cases

    TREATMENTS FOR CANKER SORES IN KIDS

    Most canker sores will heal on their own within a week or two. However, there are several treatments available to help alleviate the pain and speed up the healing process. 

    Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to reduce pain and inflammation. Topical gels or pastes containing numbing agents, such as benzocaine or lidocaine, can also be applied directly to the sore to alleviate pain. Rinsing with salt water or a baking soda solution can help to reduce inflammation and promote healing. Additionally, it is important to avoid spicy, acidic, or hard foods that can irritate the sore. 

    Maintaining good oral hygiene by brushing and flossing regularly can also help to prevent the development of canker sores. In severe cases, a medicated ointment or steroid may be prescribed by a doctor to help heal the sore.

    COMMON TREATMENTS:

    • Over-the-counter pain relievers, numbing gels or pastes

    • Rinsing with salt water or baking soda solution

    • Avoiding spicy, acidic, or hard foods

    • Maintaining good oral hygiene

    • Medication or supplements prescribed by a doctor, in severe cases

    DIFFERENCES BETWEEN CANKER SORES & COLD SORES

    It is important to note that canker sores and cold sores are two different conditions. Canker sores are not contagious and are caused by a variety of triggers, as discussed earlier. Cold sores, on the other hand, are caused by the herpes simplex virus and are highly contagious. Cold sores typically develop on the lips, outside of the mouth, and are often accompanied by fever or swollen lymph nodes.
