What Causes Sensitive Teeth? - Unveiling the Mystery!

Sensitive teeth can be a real pain, quite literally. Sensitive teeth, or dentin hypersensitivity, affects millions of people worldwide, making everyday activities like eating, drinking, and brushing teeth uncomfortable. In this blog post, we'll dive deep into What Causes Sensitive Teeth and explore how to address this common dental issue.

What Causes Sensitive Teeth

What Causes Sensitive Teeth?

There are several potential causes of sensitive teeth, including:

Tooth Decay

Tooth decay can lead to cavities, which expose the dentin layer of the tooth. This can cause increased sensitivity when consuming hot, cold, or sweet foods and beverages.

Gum Recession

Receding gums can expose the tooth's root, which is not protected by enamel, leading to sensitivity.

Tooth Enamel Erosion

Acidic foods and beverages, as well as aggressive tooth brushing, can wear away the tooth enamel, exposing the sensitive dentin layer underneath.

Cracked Teeth

Cracks or fractures in teeth can expose the dentin, causing sensitivity and pain when pressure is applied.

Teeth Grinding (Bruxism)

Grinding your teeth can wear down the enamel, exposing the dentin and leading to sensitivity.

Dental Procedures

Some dental procedures like teeth whitening, fillings, or dental cleanings can temporarily cause tooth sensitivity.

How to Treat Sensitive Teeth

If you're experiencing sensitive teeth, there are several ways to address the issue and find relief:

At-Home Remedies

  1. Desensitizing toothpaste: Switch to a toothpaste specifically designed for sensitive teeth, as mentioned earlier. These toothpastes often contain ingredients like potassium nitrate or strontium chloride, which can help alleviate sensitivity.

  2. Soft-bristled toothbrush: Using a toothbrush with soft bristles can help prevent enamel erosion and gum recession, which are common causes of sensitive teeth.

  3. Saltwater rinse: Rinsing your mouth with warm salt water can help reduce inflammation and alleviate some tooth sensitivity.

  4. Fluoride mouthwash: Using a fluoride mouthwash can help strengthen tooth enamel, providing added protection against sensitivity.

Professional Dental Treatments

  1. Dental bonding: Your dentist can apply a tooth-colored resin to the exposed tooth surface, protecting the exposed dentin and reducing sensitivity.

  2. Fluoride gel or varnish: A dentist can apply fluoride gel or varnish directly to the sensitive teeth, which can help strengthen the enamel and reduce sensitivity.

  3. Root canal treatment: If the sensitivity is caused by severe tooth decay or damage, a root canal may be necessary to remove the affected tooth pulp and relieve pain.

  4. Gum grafting: If gum recession is the cause of your sensitive teeth, gum grafting can help cover the exposed root surfaces and reduce sensitivity.

It is important to consult with your dentist to determine the best course of action for treating your sensitive teeth. They can help identify the underlying cause and recommend the most appropriate treatment.

People Also Ask

Can sensitive teeth be reversed?

The reversal of sensitive teeth depends on the cause. In some cases, addressing the underlying issue, such as tooth decay or gum recession, can help reduce sensitivity. In other cases, using desensitizing toothpaste or receiving dental treatments can help manage sensitivity.

How long do sensitive teeth last?

The duration of tooth sensitivity varies depending on the cause and treatment. For some, sensitivity may only last for a few days or weeks, while others may experience sensitivity for months or years if not properly addressed.

What is the best toothpaste for sensitive teeth?

Desensitizing toothpaste, specifically designed for sensitive teeth, can help provide relief. Look for toothpaste containing ingredients like potassium nitrate or strontium chloride, which are known to help reduce tooth sensitivity. Popular brands include Sensodyne, Colgate Sensitive, and Pronamel.

How can I prevent sensitive teeth?

To prevent sensitive teeth, maintain good oral hygiene by brushing and flossing regularly, using a soft-bristled toothbrush, and avoiding overly acidic foods and beverages. Additionally, try not to brush too hard, and consider using a night guard if you grind your teeth. Regular dental checkups and cleanings can also help prevent dental issues that cause sensitivity.


Sensitive teeth can have a significant impact on your daily life, but understanding the causes and treatments can help you find relief. By maintaining good oral hygiene, using desensitizing toothpaste, and seeking professional dental care when necessary, you can effectively manage and prevent tooth sensitivity.
