29 Oct Canker Sores
One of the most common mouth sores is a canker sore. They are small, shallow ulcers that can develop at the base of the gums or on the cheeks, and occasionally at the back of the throat. Also called “aphthous ulcers”, they are not to be confused with cold sores. Canker sores never develop outside the mouth and are NOT contagious. They can be very painful. Several factors can cause canker sores, eating spicy or acidic food, vitamin deficiencies, stress, hormones, autoimmune disorders and injury to the mouth. Most go away on their own within 2 weeks. You can use mild mouthwash or warm mild salt water to sooth the discomfort. Other treatments may be prescribed by your dentist such as steroid mouth washes.
