Canker sores: Canker sores can be caused by stress, an injury such as biting the lip, acidic foods. The exact cause is unknown. Canker sores heal on their own in 5-7 days. For protection from irritation during eating, apply orabase ointment (non prescription), which sticks to the sore to keep it covered.
