Hi, I am really scared! I think I may have an ulcer or worse, mouth cancer. I have had my 4 back teeth on left hand side of my mouth for a couple of days however, they only began to hurt after eating. Now on the 3rd day of this, my ear is starting to ache. Also today after brushing my teeth I noticed a bump on my gum, on the same side of my mouth. Is this cancer?
This is not cancer midday, probably. Avoid eating and brushing on the side where teeth are removed for 1 week. Take antibiotics and analgesics for 5 days. This bump on your gym may be because of some trauma during extraction. If your problems don't resolve within a week you need to visit your dentist.
