Have you ever suffered from a canker sore? You’re not alone. According to International Association of Oral and Maxillofacial Surgeons, 1 and 5 people have experienced canker sores. A canker sore is an ulcerated lesion or sore that can develop virtually anywhere in your mouth. The most common places you will find them are on your tongue, inner cheeks, lips, gums, and the roof of your mouth. 

Canker sores can develop randomly and are not contagious. While no one is certain what exactly causes canker sores, there are some common factors that may contribute to their development:


  • Food sensitivities
  • Diet
  • Lack of vitamins
  • Hormonal changes
  • Diseases
  • Mouth injury


You may notice a tingling or burning sensation in the area where a canker sore is beginning to develop. The appearance of a canker sore is white or gray with an outer color of red. It is painful and sensitive when touched. Try to steer clear from spicy and acidic foods and drinks. Water plays a significant part in a healthy balanced diet and can prevent canker sores from occurring. 

You should not avoid brushing your teeth. Dental hygiene is very important, especially when dealing with a canker sore. Skipping out on your daily dental routine can cause more harm than good. Bacteria and plaque can build up, causing more issues. Try using a soft bristle toothbrush and gently brush around the sore area. Also use a mild toothpaste that will decrease a burning sensation. Be sure to rinse often and floss daily to remove food particles. 

If canker sores often occur, it would be good to seek your dentist’s professional advice. Your dentist may ask you when you’ve first noticed the symptoms and if you have ever been treated for similar sores in the past. It is important to mention any issues including canker sores before your dentist begins dental work to ensure a comfortable visit.
