Question: What is this white spot on the inside of my cheek?
Answers:
That's called a canker sore. They're a real pain. Everyone says to wash your mouth out with warm salt water, it'll help clean it. If you notice there's a tiny hole in the middle, DON'T PICK AT IT. Just leave it be, I know it hurts. Brush your teeth well and avoid irritating it. If it doesn't go away for a week or more, I'd consider seeing your doctor.
Called mouth ulcers in UK. They're caused by poor diet or illness or stress. Your body is run down in some way. Get some fruit and veg inside you. In the meantime you can treat it with Bonjela or similar, salt water rinse or I use lavender essential oil.
