Mouth Sores in Children: Causes and When to See a Doctor - Dentistry

More Info

---

Mouth sores in children, particularly recurrent ones, can be a source of concern for parents. In your case, your 9-year-old child has been experiencing mouth sores almost every month for the past two years, with each sore healing within about ten days. Understanding the potential causes and when to seek medical advice is crucial for managing this condition effectively.


Common Causes of Mouth Sores in Children
1. Aphthous Ulcers (Canker Sores): These are the most common type of mouth sores in children. They are usually small, painful lesions that can appear on the inside of the cheeks, gums, or tongue. The exact cause of canker sores is not well understood, but they may be triggered by stress, certain foods (like citrus or spicy foods), or nutritional deficiencies (such as vitamin B12, folate, or iron).

2. Viral Infections: Conditions like hand, foot, and mouth disease, caused by viruses such as Coxsackievirus, can lead to mouth sores. These sores are often accompanied by other symptoms like fever and rash.

3. Bacterial Infections: Sometimes, bacterial infections can lead to sores in the mouth, particularly if there is an underlying issue like poor oral hygiene or a dental abscess.

4. Allergic Reactions: Allergies to certain foods or dental products can also cause mouth sores. If your child has recently started using a new toothpaste or mouthwash, this could be a factor.

5. Underlying Health Conditions: In some cases, recurrent mouth sores can be a sign of an underlying health issue, such as an autoimmune disorder or a systemic condition that affects the immune system.


When to See a Doctor
Given that your child has been experiencing these mouth sores regularly for two years, it is advisable to consult a healthcare professional. While occasional mouth sores are common and often benign, recurrent sores may require further investigation to rule out any underlying conditions.

1. Frequency and Duration: If the sores are occurring monthly and have been persistent over two years, this frequency warrants a medical evaluation.
2. Associated Symptoms: If your child experiences additional symptoms such as fever, difficulty swallowing, or significant pain, these could indicate a more serious condition that needs prompt attention.

3. Impact on Quality of Life: If the mouth sores are affecting your child's ability to eat, speak, or engage in normal activities, it is essential to seek medical advice.


Which Specialist to See
For recurrent mouth sores in children, the best course of action is to consult a pediatrician first. They can perform an initial evaluation and determine if a referral to a specialist is necessary. Depending on the findings, your child may be referred to:
- Pediatric Dentist: If the sores are suspected to be related to dental issues or oral hygiene.

- Pediatrician with a focus on Infectious Diseases: If there is a concern about viral or bacterial infections.

- Pediatric Gastroenterologist: If there are concerns about nutritional deficiencies or gastrointestinal issues that could be contributing to the sores.


Conclusion
In summary, while occasional mouth sores are common in children, the recurrent nature of your child's sores suggests that a medical evaluation is warranted. Consulting a pediatrician will help determine the underlying cause and appropriate treatment. Early intervention can help manage symptoms and improve your child's quality of life. Remember to keep track of any additional symptoms and the frequency of the sores, as this information will be valuable during your consultation.
