Mouth Ulcers in Children: Causes, Treatment, and Prevention

  • Share this:

Mouth ulcers, also known as canker sores or aphthous ulcers, are small, painful lesions that develop in the mouth, often on the gums, inner cheeks, lips, or tongue. While adults commonly experience mouth ulcers, they can also affect children, causing discomfort and making eating and talking painful. Understanding the causes, treatment options, and prevention measures can help parents manage and alleviate their child's discomfort.

Causes of Mouth Ulcers in Children

Minor injury or irritation: Accidental biting of the cheek, braces, rough brushing, or dental appliances can cause small cuts or abrasions in the mouth, leading to ulcers.

Infections: Viral infections, such as herpes simplex (cold sores), can cause mouth ulcers. Bacterial infections can also lead to ulceration.

Nutritional deficiencies: Insufficient intake of certain vitamins and minerals, particularly vitamin B12, iron, folate, and zinc, can contribute to mouth ulcers in children.

Food allergies or sensitivities: Certain foods can trigger an immune response in some children, leading to mouth ulcers. Common culprits include acidic foods like citrus fruits, spicy foods, chocolate, nuts, and certain food additives.

Stress or hormonal changes: Emotional stress, anxiety, or hormonal changes in the body can sometimes lead to the development of mouth ulcers.

Underlying medical conditions: In some cases, mouth ulcers can be a symptom of an underlying health condition such as celiac disease, Crohn's disease, Behçet's disease, or autoimmune disorders.

Genetic predisposition: Some children may have a genetic predisposition to developing mouth ulcers.

Oral hygiene: Poor oral hygiene can lead to bacteria build-up, increasing the risk of mouth ulcers.

Symptoms of Mouth Ulcers in Children

Pain or discomfort: Mouth ulcers can cause significant discomfort, especially when eating, drinking, or brushing teeth.

Red or white sores: The ulcers typically appear as round or oval-shaped sores with a reddish border and a whitish or yellowish center.

Difficulty eating or drinking: Due to the pain, children may experience difficulty eating certain foods or drinking acidic or spicy beverages.

Irritability or fussiness: Young children may become irritable or fussy due to the discomfort caused by mouth ulcers.

Swelling or inflammation: The area around the ulcers might appear swollen or inflamed.

Increased saliva production: Some children may experience excessive saliva production due to the presence of mouth ulcers.

Symptoms of Mouth Ulcers in Children

If your child experiences severe pain, difficulty eating or drinking, or if the ulcers last longer than two weeks, it's advisable to consult a Pediatrician.

Treatment Options for Mouth Ulcers in Children

Topical treatments: Over-the-counter gels or creams containing benzocaine or lidocaine can help numb the area and reduce pain. Antimicrobial mouth rinses or gels containing ingredients like chlorhexidine can help prevent infection and promote healing.

Pain relief: Acetaminophen or ibuprofen can help alleviate pain and reduce inflammation. Ensure you're using the appropriate dosage according to your child's age and weight.

Avoiding irritants: Encourage your child to avoid spicy, acidic, or rough foods that could irritate the ulcers. Also, acidic fruits and juices might exacerbate the pain.

Hydration and nutrition: Ensure your child stays hydrated and consumes a balanced diet rich in vitamins and minerals. Sometimes, deficiencies in vitamins like B12, iron, and folate can contribute to mouth ulcers.

Preventive Measures for Mouth Ulcers

Maintain good oral hygiene: Encourage regular and proper brushing and flossing to prevent bacteria buildup in the mouth. This helps to reduce the risk of infections that can lead to mouth ulcers.

Healthy diet: Ensure your child consumes a balanced diet rich in fruits, vegetables, and whole grains. Avoid or limit acidic, spicy, or rough-textured foods that might trigger ulcers.

Avoid trigger foods: Some children may have specific foods that trigger mouth ulcers. Pay attention to your child's diet and notice if certain foods consistently precede the appearance of ulcers. Common triggers can include citrus fruits, tomatoes, nuts, and spicy foods.

Proper hydration: Ensure your child drinks an adequate amount of water throughout the day to maintain oral health and prevent dry mouth, which can contribute to mouth ulcers.

Protective mouthguards: If your child plays contact sports, using a mouthguard can help prevent injuries to the mouth that may lead to ulcers.

Regular dental check-ups: Schedule regular dental visits for your child to ensure any oral issues are addressed promptly and to receive professional guidance on oral hygiene.

Avoid irritants: Discourage habits like chewing on pens, pencils, or biting the inside of the cheeks, as these can lead to mouth injuries that might result in ulcers.

When to Seek Medical Attention

Frequent or Persistent Ulcers: If your child frequently develops mouth ulcers or if the ulcers persist for more than two weeks without showing signs of healing, it's advisable to consult a healthcare professional.

Severe Pain or Difficulty Eating/Drinking: If the ulcers are causing significant pain, making it difficult for your child to eat, drink, or swallow, medical attention might be necessary to manage the discomfort and prevent dehydration or malnutrition.

Fever or Other Symptoms: If your child has a fever, swollen lymph nodes, or other symptoms accompanying the mouth ulcers, it could indicate an underlying condition that requires medical evaluation.

Large Ulcers or Spreading Sores: If the ulcers are exceptionally large, spreading, or showing signs of infection (increased redness, swelling, or pus), seeking medical advice is recommended.

Association with Other Health Conditions: If your child has an underlying health condition such as inflammatory bowel disease, celiac disease, or a compromised immune system, it's important to consult a healthcare provider as these conditions might influence the severity or frequency of mouth ulcers.

Mouth ulcers in children can be discomforting, but they are often manageable with proper care and attention. By understanding the causes, employing appropriate treatment methods, and taking preventive measures, parents can help their children find relief and prevent recurrent ulcers. However, consulting a healthcare professional for persistent or severe cases is essential to ensure proper diagnosis and treatment. Encouraging healthy habits and maintaining oral hygiene play a significant role in reducing the likelihood of mouth ulcers, and promoting overall oral health in children.

If your child experiences severe pain, difficulty eating or drinking, or if the ulcers last longer than two weeks, it's advisable to consult a Pediatrician.
