Why You Need to Tell Us if Your Teeth Become Sensitive to Hot or Cold
Posted on 1/1/2025 by Office - Boone DMD |
 Many people experience sensitivity in their teeth from time to time. But what does it mean if your teeth become sensitive to hot or cold? And when should you see a dentist about it?
Understanding Tooth Sensitivity Tooth sensitivity, also known as dentin hypersensitivity, occurs when the dentin, the inner layer of your tooth, becomes exposed. Dentin contains tiny tubules that lead directly to the nerve of the tooth. When exposed, these tubules can be triggered by external stimuli like hot, cold, sweet, or acidic foods and drinks, causing a sharp, shooting pain.
Common Causes of Sensitive Teeth Several factors can contribute to tooth sensitivity, including:
| • |
Gum recession: As gums recede, the dentin becomes exposed. |
| • |
Worn tooth enamel: Enamel is the hard outer layer of your teeth. Over time, it can wear down due to brushing too hard, grinding your teeth, or acidic foods and drinks. |
| • |
Cracked or chipped teeth: Cracks and chips in your teeth can expose the dentin. |
| • |
Receding fillings: Fillings can wear down over time, leaving gaps where the dentin is exposed. |
| • |
Certain dental procedures: Teeth whitening and some restorative dentistry procedures can temporarily increase sensitivity. |
Why You Should See a Dentist While occasional sensitivity may not be a cause for concern, it's important to see a dentist if you experience:
| • |
Sudden or severe sensitivity |
| • |
Sensitivity that lasts for more than a few weeks |
| • |
Sensitivity that interferes with your daily life |
Seeing a dentist can help determine the underlying cause of your sensitivity and recommend the best course of treatment.
Treatment Options for Sensitive Teeth Depending on the cause of your sensitivity, your dentist may recommend various treatments, including:
| • |
Fluoride treatments: Fluoride can help strengthen tooth enamel and make it more resistant to sensitivity. |
| • |
Desensitizing toothpaste: These toothpastes contain ingredients that block the tubules in the dentin, reducing sensitivity. |
| • |
Gum grafts: If gum recession is the cause, a gum graft can cover the exposed dentin. |
| • |
Fillings or crowns: If a cracked or chipped tooth is causing sensitivity, a filling or crown can restore the tooth and protect the dentin. |
| • |
Bonding: Bonding can be used to repair small chips or cracks in teeth. |
Maintaining Good Oral Care In addition to seeking treatment, maintaining good oral hygiene habits can help prevent and manage sensitive teeth:
| • |
Brush twice a day with a soft-bristled toothbrush and fluoride toothpaste. |
| • |
Floss daily to remove plaque and food debris between your teeth. |
| • |
Use a desensitizing toothpaste if recommended by your dentist. |
| • |
Avoid acidic foods and drinks, such as citrus fruits, sodas, and coffee. |
| • |
See your dentist for regular checkups and cleanings. |
By following these tips and addressing sensitivity promptly, you can keep your teeth healthy and comfortable. |
