A toothache that stops hurting as soon as the blood is released is not a normal clinical manifestation, and one of the possible explanations is that the inflammation breaks down and flows out. Normally if inflammation occurs in the pulp of a tooth, the pain will be very severe because the dentin and enamel that surround it are so strong that the pus between them is very difficult to flow out. However, the pain passes through other parts of the root tip or other soft tissues so that the pus overflows, and at this time, the pressure is significantly relieved and the clinical symptoms are manifested in the absence of pain. However, the absence of pain does not mean that the disease is cured, but rather a more serious situation, it is recommended to go to the stomatology department of the regular hospital for further treatment as soon as possible.
