The Top Reasons You Have Sensitive Teeth
Posted on 10/1/2025 by Glen Perio |
 Ouch! That sharp, sudden pain when you take a bite of ice cream or sip a hot cup of coffee – that's tooth sensitivity, and it's no fun. But what causes it, and more importantly, what can you do about it?
The Culprits Behind Sensitive Teeth
Tooth sensitivity occurs when the dentin, the inner layer of your tooth, becomes exposed. Dentin contains tiny microscopic tubules that lead directly to the nerve of your tooth. When exposed, these tubules allow external stimuli – like hot, cold, sweet, or acidic foods and drinks – to reach the nerve, triggering that painful sensation.
Several factors can contribute to exposed dentin and tooth sensitivity, including:
| • |
Gum recession: As we age, our gums naturally recede, exposing the sensitive dentin at the root of the tooth. |
| • |
Tooth wear: Years of brushing too hard, using abrasive toothpaste, or grinding your teeth can wear down tooth enamel, exposing the dentin beneath. |
| • |
Cracked or chipped teeth: Damage to the outer enamel layer can allow access to the dentin. |
| • |
Dental treatments: Certain procedures like teeth whitening or fillings can temporarily increase sensitivity. |
| • |
Underlying medical conditions: Some medical conditions, like acid reflux or Sjogren's syndrome, can affect oral health and contribute to sensitivity. |
Taking Control of Sensitivity
The good news is that tooth sensitivity is often manageable and even preventable. Here are some tips to help you take control:
| • |
Practice gentle oral care: Use a soft-bristled toothbrush and avoid brushing too hard. Opt for a toothpaste formulated for sensitive teeth. |
| • |
Protect your gums: Flossing daily and using an antiseptic mouthwash can help maintain healthy gums and prevent recession. |
| • |
Be mindful of your diet: Limiting acidic foods and drinks can help reduce sensitivity. |
| • |
Seek professional help: If your sensitivity is severe or persistent, consult your dentist. They can identify the underlying cause and recommend appropriate treatment options, including fluoride treatments, desensitizing toothpaste, gum grafting, or restorative dentistry procedures like fillings or crowns. |
Preventing Future Sensitivity
By understanding the causes of tooth sensitivity and adopting good oral hygiene habits, you can significantly reduce your chances of experiencing this discomfort. Regular dental checkups and professional cleanings are also crucial for maintaining oral health and preventing future sensitivity issues.
Remember, sensitive teeth don't have to control your life. By taking the right steps, you can regain control and enjoy all your favorite foods and drinks without pain.
