Red Flags & When to Go In Person for Mouth Sores in Children

Audience: pediatric

Mouth sores in children are common and often caused by minor issues like irritation or viral infections. Many times, these can be safely evaluated and managed through telemedicine. However, some signs may indicate a more serious problem that requires in-person care. This guide helps parents and caregivers understand when it is safe to use telemedicine for mouth sores and when to seek urgent medical attention. Early recognition of warning signs can prevent complications and ensure your child receives the right care. Telemedicine can offer quick advice, symptom assessment, and guidance on home care, but it cannot replace physical exams or tests needed for serious conditions. Always watch for red flags such as difficulty swallowing, high fever, or persistent pain. Knowing these signs helps keep your child safe and comfortable.

Red flags — go in person / ER

• Difficulty swallowing or breathing — seek emergency care immediately.
• High fever above 38.5°C (101.3°F) lasting more than two days — arrange in-person evaluation.
• Mouth sores that spread rapidly, are very painful, or last more than two weeks — see a healthcare provider in person.

What telemedicine can do

• Assessment of mild mouth sores with no severe symptoms.
• Providing advice on home care and symptom management.
• Determining when in-person care is needed.

What telemedicine cannot do

• Physical examination to rule out serious infections or conditions.
• Emergency treatment for airway or swallowing difficulties.
• Diagnostic tests such as blood work or cultures.

Common Causes of Mouth Sores in Children

Mouth sores can appear for many reasons, including minor injuries from biting or brushing, viral infections like hand-foot-and-mouth disease, or allergic reactions. They often look like small ulcers or blisters inside the mouth or on the lips. Most sores heal on their own within one to two weeks without special treatment. Keeping the mouth clean and avoiding spicy or acidic foods can help ease discomfort.

When Telemedicine Can Help

Telemedicine allows you to connect with a healthcare provider remotely to discuss your child's mouth sores. Providers can ask about symptoms, look at pictures or videos of the sores, and give advice on home care. This is helpful for mild cases without worrying signs, saving time and avoiding travel. Providers can recommend pain relief options and when to watch for changes.
