What to do when a 53 year old woman loses an old tooth and the root hurts?

The correct term for old teeth is permanent teeth, permanent tooth stump pain can be extracted, can also be thoroughly anti-inflammatory after restorative treatment, specific as follows.
1. Extraction: For the stumps that have no significance to be retained and are often inflamed, swollen and painful, affecting normal life, they should be extracted as soon as possible.
2. Restorative treatment: If there are fewer teeth left in the mouth, anti-inflammatory and pain-relieving treatments can be carried out on the stump, and after the inflammation has been completely eliminated, titanium or cobalt-chromium alloy stumps can be cemented to the root canals with glass ionomer cementing and then crowns can be restored, or overdentures can be directly designed and made on the stumps to exercise the function of mastication.
If the pain of the stump is severe, or accompanied by other symptoms, you should go to the hospital in time.
