Why does toothache stop hurting after bleeding?

The phenomenon of toothache relief after bloodletting primarily stems from the rupture of inflammation and the discharge of pus. When an abscess occurs in the periodontal or periapical area, accumulated pus within the gums causes a sensation of pressure and pain. Once the pus is drained through bloodletting, the internal pressure in the gums rapidly decreases, significantly reducing or eliminating the pain. However, this relief does not mean the condition has been completely cured. Although bloodletting therapy may temporarily alleviate symptoms—such as clearing heat, detoxifying, cooling the blood, and relieving pain—it does not address the underlying dental or periodontal problem. Therefore, even though pain may temporarily subside after bloodletting, patients should still promptly visit the dental department of a正规 hospital for further examination and treatment to ensure the disease is fundamentally resolved. Additionally, maintaining good oral hygiene and avoiding spicy or irritating foods are crucial for preventing both the occurrence and recurrence of toothaches.
