When gum pain occurs one month after wisdom tooth extraction, it is very likely that new soft tissue has been created in the extraction socket. The new soft tissue is usually granulation tissue, which is not the same as normal gums and has no associated toughness, but only a soft tissue filling in the extraction socket, which is likely to bleed easily and have inflammation, which is relatively normal. If the patient brushes the newly grown soft tissue when brushing the teeth, it may feel different from the other gums and even painful. At this time, the patient should not give up cleaning this location to avoid the formation of plaque in this location, which will affect the front teeth decay, and wait for three months or so after the alveolar bone has completely grown flat, the state of the gums will return to the same state as other parts of the gums, and there will be no more gum pain at this time.
