Why Do My Teeth Feel So Sensitive?
Posted on 10/15/2025 by Cooley Smiles Kenmore |
 We've all experienced that sudden, sharp pain when enjoying a cold treat or a hot cup of coffee. While a fleeting moment of discomfort is normal, persistent tooth sensitivity can be a sign of an underlying issue.
What is Tooth Sensitivity?
Tooth sensitivity, also known as dentin hypersensitivity, is a short, sharp pain that arises when the inner layer of your tooth, called dentin, is exposed. Dentin contains tiny tubules that lead directly to the nerve of your tooth. When these tubules are exposed due to receding gums, worn enamel, or a chipped tooth, external stimuli like hot, cold, sweet, or acidic foods and drinks can trigger a painful response.
Causes of Tooth Sensitivity
Several factors can contribute to tooth sensitivity:
1. Receding Gums: As we age or due to gum disease, the gums can recede, exposing the dentin.
2. Worn Enamel: Enamel is the hard, outer layer of your teeth. Over time, acidic foods and drinks, teeth grinding, and improper brushing can wear down the enamel, exposing the dentin.
3. Cracked or Chipped Teeth: Damage to the tooth's surface, such as a crack or chip, can expose the dentin.
4. Dental Procedures: Certain dental procedures like fillings, crowns, and professional teeth whitening can temporarily increase sensitivity.
5. Other factors: Teeth grinding, certain medications, and medical conditions like acid reflux can also contribute to tooth sensitivity.
Treatment Options for Tooth Sensitivity
The good news is that tooth sensitivity is often treatable. Depending on the cause and severity, different options are available:
1. Desensitizing Toothpaste: These toothpastes contain ingredients that block the tubules in the dentin, reducing sensitivity.
2. Fluoride Treatment: Fluoride strengthens tooth enamel and can help remineralize areas where enamel has been eroded.
3. Bonding or Fillings: If the sensitivity is caused by a chipped or cracked tooth, a filling or bonding can help restore the tooth's surface.
4. Gum Grafts: In cases of severe gum recession, a gum graft can be performed to cover the exposed root surface.
5. Restoration Dentistry: In some cases, crowns or other restorative procedures may be necessary to address the underlying cause of the sensitivity and protect the tooth.
Tips for Managing Tooth Sensitivity
While seeking professional care is essential, you can also manage tooth sensitivity at home:
1. Use a soft-bristled toothbrush and gentle brushing technique.
2. Avoid acidic foods and drinks.
3. Use a straw when drinking cold beverages.
4. Consider desensitizing toothpaste or mouthwash.
5. Consult your dentist to rule out any underlying dental issues.
If you experience persistent or severe tooth sensitivity, don't hesitate to schedule an appointment with your dentist. They can diagnose the cause of your sensitivity and recommend the most appropriate treatment to restore your oral comfort and enjoy your favorite foods and drinks without pain.
