Common treatments for cold sores in the mouth include taking over-the-counter painkillers such as acetaminophen and ibuprofen to manage pain, rinsing with a mouth rinse containing baking soda and using products like Orajel and Anbesol to numb pain in the mouth, notes WebMD. These treatments are used to manage pain and speed healing.
Another common way to speed the healing of cold sores in the mouth is to avoid acidic foods, which irritate and inflame affected areas, according to WebMD. In addition to these methods of treatment, cold sore outbreaks can be made less frequent by avoiding prolonged exposure of lips to sunlight and avoiding intimate contact with those who have cold sores.
Cold sores can also be made less frequent by avoiding indirect contact with those who have cold sores. Common examples of indirect contact include sharing cups, razors or other objects with people who have cold sores. Another common method of treating and avoiding cold sores is to pay attention to and avoid foods that seem to induce outbreaks. These vary from person to person, but some prevalent examples are gelatin, nuts and chocolate, explains WebMD. Most of these methods manage symptoms and prevention, since cold sores tend to heal on their own without intervention.
