Bleeding for pulpitis is useless, and dental treatment is necessary. In the early stages of pulpitis, the pulp can be soothed, which is often seen in reversible pulpitis, and early soothing can relieve pain. Sometimes the pulp can revert to a normal state. If it's the late stage, the tissue pressure inside the pulp is relatively high; in this case, pulp opening can be performed to relieve pressure, and dental treatment is necessary, as bleeding is useless. If the tooth undergoes fundamental treatment promptly in the early stages of pulpitis, the inflammation of the pulp can be controlled in time. Otherwise, further development may lead to inflammation of the root tip. Apical inflammation can sometimes result in abscesses or even facial swelling.
