This is termed as a 'traumatic ulcer' in the dental literature. Nothing to worry about though as it's a common occurrence. It requires no treatment and will go down on its own within a week or two depending on its severity. You can apply local anesthetic gel if it's bothering you, or if you're having pain or burning sensation while eating hot/spicy foods.
If it persists after week 2, consider a consult with your dentist.
Wishing you a good health.
