Tooth pain rarely stays still. A dull throb becomes a sharp pulse, swelling spreads and sleep disappears. People try salt water, clove oil or leftover pain tablets, but these only mask symptoms. Worse, a cracked tooth can split further, a lost filling exposes the nerve, and a knocked-out tooth dries out. Waiting turns a fixable problem into a complex case. Infections can move from a localized abscess to facial swelling with fever.
