Why do I have a bump on my gums after tooth extraction? Tissue Injury Leads to Mouth Ulcers When teeth are difficult to remove, for example, when the roots are deeply embedded such as in the case of wisdom teeth, dentists need to use more force to remove them.
If you notice a small amount of bleeding an hour after extraction, place a moist tea bag on the extraction site and bite down tightly to apply pressure to the area.
