Overview of Canker Sores and Fever Blisters

• Canker sores are non-contagious ulcers inside the mouth. Fever blisters, or cold sores, are contagious blisters caused by the herpes simplex virus, usually around the lips.

Over-the-Counter (OTC) Medications and Ointments

• For canker sores: Use benzocaine gels like Anbesol or protective pastes like Orabase.
• For fever blisters: Consider antiviral creams such as acyclovir ointment (e.g., Zovirax).

Prescription Medications

• If OTC treatments are ineffective, consult a healthcare provider for stronger antiviral creams or oral antivirals.

Supportive Care and Home Remedies

• Use pain relievers like paracetamol or ibuprofen for discomfort.
• Maintain oral hygiene and avoid irritants like spicy foods.

When to Seek Medical Advice

• Seek professional evaluation for severe pain, spreading lesions, or frequent recurrences.

Relevant Medical Specialties

• Dentists and dermatologists can provide specialized care for these conditions.
