### Common Causes of Tooth Pain and When to See a Dentist Tooth pain can be caused by various factors, some more serious than others. Identifying the cause is the first step to alleviating the pain. Here are some common causes and what you can do about them: **1. Cavities:** Holes in the teeth caused by decay. Poor dental hygiene and sugary foods can lead to cavities. **2. Tooth Abscess:** A pocket of pus caused by bacterial infections, often from untreated cavities or gum disease. **3. Pulpitis:** Inflammation of the tooth's pulp, often due to untreated cavities. **4. Enamel Erosion:** Worn-down enamel can make teeth sensitive to hot, cold, and sweet foods. **5. Old or Cracked Fillings:** These can expose inner layers of teeth, increasing sensitivity. **6. Receding Gums:** Gum tissue pulling away from the tooth, exposing the root and causing pain. **7. Gingivitis:** A mild form of gum disease that can escalate if untreated. **8. TMJ Disorders:** Pain in the jaw joint that can radiate to the teeth. **9. Sinus Infections:** Can cause upper rear teeth to hurt due to pressure. **10. Impacted Teeth:** Teeth that don't break through the gumline, often wisdom teeth. **11. High Blood Sugar:** Can increase bacteria and plaque, leading to gum disease and cavities. **12. Heart Conditions:** Jaw pain can sometimes indicate serious conditions like angina or a heart attack. **When to See a Dentist:** If your tooth pain is severe, lasts more than a day or two, or is accompanied by other symptoms like fever or swelling, see a dentist immediately. Good dental habits like brushing and flossing daily can prevent many causes of tooth pain. If you have underlying conditions like diabetes or heart disease, consult your doctor for appropriate treatment. **Emergency Situations:** If you experience jaw pain along with symptoms like chest pain, shortness of breath, or dizziness, seek emergency medical attention immediately. **Treatment Options:** Depending on the cause, treatments can range from fillings and root canals to antibiotics for infections. Always consult a professional for the best course of action.
