Prescription Medication
Medications with corticosteroids, analgesics and anesthetics can also be indicated by the dentist, depending on the patient’s condition. Taking antiviral drugs can help speed up the healing of canker sores and accelerate its natural remission. These drugs, which include valacyclovir, famciclovir, and acyclovir, require a prescription from your dentist or primary care physician. These drugs are most effective if taken before the blisters appear. When you notice that a sore is about to break out — burning, tingling, redness, and swelling in the area — drugs can make it easier to heal or even prevent it from happening. Oral steroid [6] are also very effective against canker sores.
