Why Does Cold Reduce Dry‑Socket Pain Only Briefly?
Cold constricts superficial vessels and slows nerve conduction, providing fast numbing and swelling control. Dry socket (alveolar osteitis) exposes bone and nerves after a clot dislodges; cold tempers that acute inflammation. Yet sustained vasoconstriction beyond 24 h may limit oxygen and nutrients, extending healing time.
Key data: A 2024 meta‑analysis reported 30 % lower pain scores on surgery day in patients using three cold cycles versus none. The benefit vanished by day two, while those who added warmth healed 1.3 days faster.
