What causes cancer sores?

My health app logged that my mouth ulcers usually pop up when my sleep tracker shows poor deep sleep and high stress. Nutritional deficiencies, like low vitamin B12 or iron, are also very common triggers. Tracking your symptoms alongside your diet can give you great insights before you visit your dentist.

Please do not apply random pastes or home remedies you read about online on chronic mouth sores. A persistent, non-healing ulcer in the mouth can sometimes be a sign of oral cancer, especially if there is a history of tobacco use. Get it clinically examined by a dentist or an ENT specialist to get an accurate diagnosis.

I was researching this because I get them often, and I found out they are actually called canker sores, which are non-contagious. They can be triggered by minor mouth injuries, acidic foods, or even an immune reaction. It is quite annoying but usually harmless, though persistent ones definitely need medical evaluation.

Oh, these are so painful and make eating absolute torture! I usually get them when I am super stressed during my exams or if I accidentally bite the inside of my cheek. I use a soothing oral gel recommended by my doctor and try to avoid spicy food until it heals.
