Viral cold sore therapies are designed to help reduce the symptoms and shorten the healing time for patients who are infected with herpes simplex virus that causes cold sores. These sores can be painful and embarrassing for patients, and being ready to prescribe a remedy or recommend an over-the-counter option is a great way to help patients. Dental professionals may notice oral cold sores before other medical professionals, so they are best positioned to care for patients who suffer from cold sores.
