How to Avoid Sensitive Teeth
Posted on 4/1/2025 by Dr. Michael Wockenfus |
 Have you ever winced at the feeling of ice cream on your teeth, or gasped after taking a sip of hot coffee? If so, you're not alone. Millions of people experience sensitive teeth, a condition that can range from mildly annoying to downright painful.
But the good news is that there are several things you can do to avoid sensitive teeth and enjoy your favorite foods and drinks without discomfort.
What Causes Sensitive Teeth?
Sensitive teeth occur when the dentin, the layer beneath the enamel of your teeth, becomes exposed. Dentin contains tiny tubules that lead directly to the nerve of the tooth. When these tubules are exposed, external stimuli like hot, cold, sweet, or acidic foods and drinks can trigger pain.
There are several factors that can contribute to sensitive teeth, including:
| • |
Receding gums: As gums recede, they expose the dentin, making teeth more sensitive. This can occur due to gum disease, aggressive brushing, or even the natural aging process. |
| • |
Tooth enamel erosion: The enamel is the hard outer layer of your teeth that protects them from wear and tear. Over time, the enamel can erode due to factors like acidic foods and drinks, grinding your teeth, or even certain medications. |
| • |
Chipped or cracked teeth: Damage to the enamel, such as chips or cracks, can expose the dentin and lead to sensitivity. |
| • |
Dental procedures: Certain dental procedures, such as fillings or crowns, can temporarily increase tooth sensitivity. |
How to Prevent Sensitive Teeth
The good news is that there are several things you can do to prevent sensitive teeth and reduce the pain you may already be experiencing. Here are a few tips:
| • |
Practice good oral hygiene: Brush your teeth twice a day with a soft-bristled toothbrush and fluoride toothpaste. Be sure to brush gently and avoid scrubbing too hard. Floss daily to remove plaque and food particles that can contribute to gum disease. |
| • |
Use a toothpaste for sensitive teeth: Many toothpastes are specially formulated to help desensitize teeth by blocking the tubules that lead to the nerve. Look for a toothpaste that contains potassium nitrate or strontium chloride. |
| • |
Avoid acidic foods and drinks: Acidic foods and drinks, such as citrus fruits, juices, and sodas, can erode the enamel and increase sensitivity. Try to limit your intake of these foods and drinks, or rinse your mouth with water after consuming them. |
| • |
Don't grind your teeth: Teeth grinding, or bruxism, can wear down the enamel and increase sensitivity. If you grind your teeth, talk to your dentist about wearing a mouthguard at night. |
| • |
See your dentist regularly: Regular dental checkups and cleanings are essential for maintaining good oral health. Your dentist can identify and treat any problems that may be contributing to your sensitive teeth. |
Additional Tips
| • |
Use a straw: When drinking cold or acidic beverages, use a straw to minimize contact with your teeth. |
| • |
Eat crunchy foods: Crunchy foods, such as carrots and apples, can help stimulate saliva production, which can help to neutralize acids in the mouth. |
| • |
Avoid using whitening products: Whitening products can increase tooth sensitivity. If you want to whiten your teeth, talk to your dentist about options that are less likely to cause sensitivity. |
With a little effort, you can avoid sensitive teeth and enjoy a pain-free smile. If you are experiencing sensitive teeth, be sure to see your dentist to rule out any underlying problems.
