### How Sinus Infections Cause Toothaches and Treatments to Relieve Pain Sinus infections, also known as sinusitis, can cause toothaches due to the proximity of the sinuses to the upper teeth. When the sinuses become inflamed and swollen, the pressure can affect the roots of the upper teeth, leading to pain. This pain is usually felt in the upper rear teeth and can sometimes spread to the lower teeth. #### Symptoms of Sinus Infection - Facial pain or pressure, especially under the eyes or around the nose - Congestion or nasal blockage - Thick nasal discharge - Reduced sense of smell and taste - Fever - Fatigue #### Home Remedies 1. **Stay Hydrated**: Drink plenty of water to thin mucus and reduce pressure. 2. **Steam Inhalation**: Inhale steam from hot water to open nasal passages. 3. **Saline Rinse**: Use a saline solution to rinse your sinuses and clear away allergens. 4. **Hot Liquids**: Drink hot liquids like soup and tea to soothe the throat and reduce congestion. #### Over-the-Counter Treatments - **Decongestant Nasal Sprays**: Use for short-term relief, but not for more than 3 days. - **Nasal Steroid Sprays**: Can be used for longer periods to reduce inflammation. #### Prescription Treatments - **Antibiotics**: Only if a bacterial infection is suspected and other treatments are ineffective. - **Prescription Nasal Sprays**: Stronger medications to reduce inflammation and congestion. #### When to See a Doctor - If symptoms last longer than 12 days - If you experience severe pain or swelling - If over-the-counter treatments are ineffective Treating the sinus infection usually resolves the toothache. If tooth pain persists after sinus symptoms improve, consult a dentist to rule out dental issues.
