### Common Causes of Sudden Tooth Pain and When to See a Dentist Sudden tooth pain can be alarming, but it is often treatable. Here are 10 common reasons why your teeth might hurt and when you should see a dentist: 1. **Tooth Sensitivity**: Caused by worn enamel or exposed nerves. Pain occurs with hot or cold foods and drinks. 2. **Gum Recession**: As gums wear away, roots of teeth become exposed, leading to sensitivity and increased risk of infections. 3. **Dentin Hypersensitivity**: Affects about 12% of people. Caused by acidic diets, hard brushing, and other factors. 4. **Tooth Decay**: Cavities can progress to infections, causing pain. 5. **Gum Disease**: Affects over 47% of adults over 30. Early stages are called gingivitis. 6. **Cracked Tooth or Crown**: Even slight cracks can cause pain and sensitivity. 7. **Sinus Infection**: Can cause pain in teeth and jaw due to pressure on nerve endings. 8. **Teeth Grinding**: Leads to chronic sensitivity by wearing down enamel. 9. **Recent Dental Work**: Fillings or drilling can temporarily increase sensitivity. 10. **Teeth Whitening**: Whitening products can cause temporary sensitivity. If you experience sudden tooth pain, consult your dentist. They can recommend treatments like sensitivity-reducing toothpaste or necessary procedures like fillings or extractions. Don't ignore severe symptoms; seek professional help immediately.
