Why Do Teeth Hurt During Sinus Infections? Referred Pain
By Dr. Navaneeth K. Unni•Published on 2027-09-20•Patient Group: Adults
Clinical Overview & Pathophysiology
It is common for individuals with a sinus infection to experience a dull, throbbing ache in their upper teeth, leading them to suspect a dental cavity. This referred pain occurs because the floor of the maxillary sinus cavity rests directly above the roots of the upper molar and premolar teeth, sharing nerve pathways.
Key Clinical Facts & Indicators
- Referred Upper Dental Ache: Dull, aching pain in the upper rear teeth, often affecting multiple teeth simultaneously.
- Maxillary Sinus Pressure: Facial pressure and tenderness when pressing on the cheekbones.
- Pain on Impact: Increased tooth discomfort when walking, jumping, or when tapping the teeth gently.
- Nasal Congestion Block: Accompanying symptoms of thick nasal discharge and sinus headache.
Lifestyle & Nutritional Guidelines
Treat the underlying sinus congestion. Use warm steam inhalations and nasal saline rinses to drain sinuses. Apply warm compresses to the cheeks. Stay hydrated (use our Water Intake Calculator) to keep mucus thin. Consult a dentist if tooth pain persists after sinus clearing.
Frequently Asked Questions
Q: How can I tell if tooth pain is from a sinus infection or a cavity?Sinus-induced tooth pain usually affects multiple upper teeth, worsens when bending forward, and is accompanied by nasal congestion.
Q: Can sinus pressure damage my teeth?No, sinus pressure causes nerve irritation and referred pain but does not damage the tooth structure or cause cavities.
