Why Do You Have Sensitive Teeth?
Posted on 8/1/2025 by West End Dental |
 We all know the feeling: a sharp, sudden pain in your teeth when you eat or drink something hot, cold, or sweet. This pain is often described as a "zing" or a "stab," and it can be quite uncomfortable. If you experience this frequently, you might be one of the millions of people who suffer from sensitive teeth.
In this article, we'll explore the causes of sensitive teeth, how to prevent them, and what you can do to find relief.
What Causes Sensitive Teeth?
The outermost layer of your teeth is called enamel. It's a hard, protective coating that shields the inner layers of your teeth, including the dentin and pulp. The dentin contains tiny tubes that lead to the pulp, which is where the nerves and blood vessels are located.
When the enamel is worn away or damaged, the dentin tubules become exposed. This can happen due to several factors, including:
| • |
Tooth decay: Cavities can eat away at the enamel, exposing the dentin beneath. |
| • |
Gum recession: As gums recede, the root surface of your teeth becomes exposed. The root surface doesn't have enamel, so it's more sensitive. |
| • |
Cracked teeth: Cracks in your teeth can allow bacteria to reach the dentin and pulp, causing sensitivity. |
| • |
Worn fillings: Over time, fillings can wear down and leave gaps around the edges of the tooth. This can expose the dentin and make the tooth sensitive. |
| • |
Aggressive brushing: Brushing your teeth too hard or using a hard-bristled toothbrush can wear away the enamel and irritate the gums. |
| • |
Acidic foods and drinks: Acidic foods and drinks, such as citrus fruits, soda, and wine, can erode the enamel and make teeth more sensitive. |
| • |
Grinding your teeth: Grinding your teeth (bruxism) can put stress on the teeth and cause them to become sensitive. |
How to Prevent Sensitive Teeth
There are several things you can do to prevent sensitive teeth:
| • |
Practice good oral hygiene: Brush your teeth twice a day with a soft-bristled toothbrush and fluoride toothpaste. Floss daily to remove plaque and food particles from between your teeth. |
| • |
See your dentist regularly: Get regular checkups and cleanings to catch any problems early. Your dentist can also recommend treatments to strengthen your enamel or protect exposed dentin. |
| • |
Use a toothpaste for sensitive teeth: These toothpastes contain ingredients that can help block the dentin tubules and reduce sensitivity. |
| • |
Avoid acidic foods and drinks: Limit your intake of acidic foods and drinks, and rinse your mouth with water after consuming them. |
| • |
Don't grind your teeth: If you grind your teeth, talk to your dentist about getting a mouthguard to wear at night. |
What to Do If You Have Sensitive Teeth
If you already have sensitive teeth, there are several things you can do to find relief:
| • |
Use a toothpaste for sensitive teeth: As mentioned above, these toothpastes can help block the dentin tubules and reduce sensitivity. |
| • |
Apply a desensitizing gel: These gels contain ingredients that can help numb the nerves in your teeth. |
| • |
Use a fluoride rinse: Fluoride can help strengthen your enamel and make your teeth less sensitive. |
| • |
Avoid triggers: Identify the things that trigger your sensitivity and try to avoid them. This may include hot or cold foods and drinks, acidic foods, or sugary foods. |
| • |
See your dentist: If your sensitivity is severe or doesn't improve with home treatment, see your dentist. They may be able to identify the underlying cause of your sensitivity and recommend more specific treatment options. |
Prevention Dentistry is Key
The best way to deal with sensitive teeth is to prevent them from happening in the first place. By practicing good oral hygiene, seeing your dentist regularly, and avoiding triggers, you can keep your teeth healthy and strong.
