Some experts believe that these sores might be a result of rubbing or bite injury. Stress also plays a role in bringing them on. Other factors that can trigger them are exposure to certain foods or chemicals, Dehydration and hormonal shifts.


Is It Really a Canker Sore?
It is important to differentiate whether the ulcer in your mouth is a canker sore or a cold sore because a cold sore is contagious while a canker sore is not.


The main differences between the two are:



  • Location: A canker sore is almost always inside the oral cavity, on the inside of lips, tongue or on the gums, while a cold sore is always present outside the moth, on or around the lips.

  • Appearance: Canker sores are small open ulcers with a white, yellow or grey base, surrounded by inflamed soft tissue. They can be single or multiple. Cold Sores are typically found in groups of red, fluid filled blisters.

  • Cause: While the exact cause of canker sores is unknown, they are definitely non-infectious and are brought out by a number of triggers as mentioned above. Cold sores are caused by Hpv virus (Herpes Simplex virus). Besides, fatigue, stress, exposure to certain conditions and injury can trigger them.
