Periapical periodontitis gum pain?

Patients with periapical periodontitis, gums may show pain. For example, patients with acute suppurative periapical periodontitis, then the gums are swollen. When we touch the gums with our hands, then there is a clear pain reaction. If there is no suppuration, then the acute serous periapical periodontitis stage, gums are actually red, there is inflammation, with the hand to press the gums will also show pain reaction. In short, acute periapical periodontitis will most likely show pain in the corresponding part of the gums, this part of the gums is the root relative to the root apex of the gums. Therefore, when we do periapical periodontitis treatment, if you need to inject anesthetics as far as possible away from this part of the gum tissue, do not hit local infiltration anesthesia but hit local block anesthesia.
