At some point, many of us have suffered from canker sores, which should not be confused with cold sores or fever blisters. Cold sores are caused by the herpes virus and usually occur on or around the lips. Canker sores are small, painful, red bordered ulcers with a white or yellowish base. They occur inside the mouth generally on the more movable tissue; like under the tongue, cheeks, and inside the lips. While their exact cause is uncertain it is thought that fatigue, stress, and trauma seem to increase the likelihood of occurrence. Canker sores are not contagious and they usually heal on their own in 7 to 10 days. To promote healing of a canker sore you can:
-rinse with warm saltwater or an antimicrobial mouthrinse
-maintain good oral hygiene
-avoid hot or spicy foods
See your dentist for any further guidance or diagnosis.
