However by placing a tablet directly on your tooth or against your gums, will cause something called aspirin burn, which is also medically known as an ulceration, where the tissue is eroded, denuded, inflamed and/or dying (tissue necrosis). Therefore, if the cause of the pain is due to gum inflammation, aspirin placed on it will make it much worse. If the cause of the pain is from tooth decay and exposure of the nerve, placing aspirin in that area will make it MUCH worse.
