Toothaches often feel worse at night because lying down increases blood flow to the head, creating extra pressure that makes a sore tooth throb. Additionally, the lack of daily distractions makes you more aware of the pain, while nighttime habits like teeth grinding can further irritate inflamed nerves.

Common reasons for increased nighttime dental pain include:

• Blood Pressure: Lying flat causes blood to pool in the head, intensifying pressure on sensitive dental pulp.
• Bruxism: Unconscious clenching or grinding during sleep puts physical stress on decayed or cracked teeth.
• Sinus Pressure: Congestion can press against the roots of the upper teeth when you are in a horizontal position.
• Late-night Triggers: Consuming sugary, hot, or cold snacks before bed can aggravate existing cavities or sensitivity.
