Why Toothache Gets Worse at Night — The Real Reason Behind It.
Many people notice their toothache feels more intense when they lie down — especially at night. It’s not psychological. It’s biological.
When you lie flat, gravity shifts blood flow toward your head. This increases blood volume around the infected tooth, raising internal pressure in the pulp chamber — a closed space that can't expand.
The result? Throbbing, pulsing pain that worsens even if you’re resting.
In cases of irreversible pulpitis or deep decay, the inflamed nerve tissue reacts more aggressively when the body is in a horizontal position. Add to that the lack of distractions at night, and the pain feels magnified.
If your tooth hurts more when lying down, it's a red flag that the pulp may be severely inflamed or infected — and likely needs immediate dental treatment such as root canal therapy.
Delaying may lead to abscess, bone infection, or facial swelling.
