Unlock the Secret to a Pain-Free Smile: The Top Causes of Tooth Sensitivity

Updated: Jul 6, 2023

Have you ever experienced a sharp pain or discomfort in your teeth when you consume something hot or cold? If yes, then you might have sensitive teeth. Sensitive teeth can be a common dental problem that affects millions of people worldwide. In this blog post, we will discuss sensitive teeth, their causes, and the various treatment options available.

What are Sensitive Teeth?

Sensitive teeth are a dental condition where the teeth become sensitive to hot, cold, sweet, or sour substances. The pain or discomfort can be sharp, sudden, or lingering. This sensitivity can make it difficult to eat, drink, or even breathe.

What Causes Teeth Sensitivity?

Teeth sensitivity can be caused by a variety of factors, including:

  1. Brushing too hard: Overbrushing or brushing too hard can wear down the enamel of the teeth, which can lead to sensitivity.

  2. Tooth decay: Tooth decay can cause small holes or cavities to form in the teeth, which can expose the sensitive inner layers of the teeth.

  3. Gum disease: Gum disease can cause the gums to recede, which can expose the sensitive root of the tooth.

  4. Teeth grinding: Grinding or clenching your teeth can wear down the enamel and expose the sensitive layers of the teeth.

  5. Acidic foods and drinks: Consuming acidic foods and drinks can erode the enamel of the teeth, making them more sensitive.

Symptoms of Teeth Sensitivity

The symptoms of teeth sensitivity can vary from person to person, but common symptoms include:

  • Pain or discomfort when eating or drinking hot or cold foods and drinks.

  • Pain or discomfort when consuming sweet or acidic foods and drinks.

  • Pain or discomfort when brushing or flossing.

  • Sensitivity to cold air or water.

Preventing Teeth Sensitivity

Fortunately, there are several things you can do to prevent teeth sensitivity, including:

  1. Brushing gently: Brushing gently with a soft-bristled toothbrush can help prevent enamel erosion and gum recession.

  2. Using desensitizing toothpaste: Desensitizing toothpaste can help reduce tooth sensitivity by blocking the nerve endings in the teeth. Look for toothpaste that contains potassium nitrate or strontium chloride.

  3. Maintaining good oral hygiene: Brushing and flossing regularly can help prevent tooth decay and gum disease, which can lead to tooth sensitivity.

  4. Limiting acidic foods and drinks: Try to limit your consumption of acidic foods and drinks, such as citrus fruits, soda, and sports drinks. If you do consume them, rinse your mouth with water afterward to help neutralize the acid.

  5. Wearing a mouthguard: If you grind or clench your teeth, wearing a mouthguard at night can help prevent enamel erosion and tooth sensitivity.

  6. Getting regular dental checkups: Regular dental checkups can help catch and treat dental problems before they lead to tooth sensitivity.

And if you do experience sensitivity already, here are some treatment options:

Sensitive teeth can be treated with a variety of options. The treatment option depends on the severity of the sensitivity and its underlying cause. Some of the common treatment options are:

  • Desensitizing Toothpaste

Desensitizing toothpaste is a commonly used treatment option for sensitive teeth. It contains compounds that help block the transmission of sensations from the tooth surface to the nerve. This helps to reduce the sensitivity and pain. It is recommended to use desensitizing toothpaste for at least two weeks to see the results.

  • Dental Bonding

Dental bonding is a process where a tooth-colored resin material is applied to the tooth surface to cover the exposed root surfaces. This can help to reduce sensitivity and improve the appearance of the teeth.

  • Dental Sealants

Dental sealants are a thin, protective coating applied to the chewing surfaces of the molars to protect them from decay. They can also help to reduce sensitivity.

  • Gum Graft Surgery

Gum graft surgery is a process where a small amount of tissue is taken from the roof of the mouth and grafted onto the exposed root surfaces. This can help to protect the root surfaces and reduce sensitivity.

  • Root Canal Treatment

If the sensitivity is caused by tooth decay or infection, root canal treatment may be necessary. This treatment involves removing the infected or decayed pulp from the tooth and sealing the tooth with a filling or crown.


As you can see, teeth sensitivity can be a frustrating and painful condition, but it is preventable and treatable. By taking good care of your teeth and visiting your dentist regularly, you can reduce your risk of tooth sensitivity and maintain a healthy, beautiful smile. Remember to brush gently, use desensitizing toothpaste, limit acidic foods and drinks, and wear a mouthguard if you grind your teeth.

Oh, and did you know?:

  1. Professional and over-the-counter teeth whitening procedures are a big culprit of sensitive teeth because these products can temporarily cause teeth to feel sensitive.

  2. Women are more likely than men to experience tooth sensitivity.

  3. The most common teeth affected by sensitivity are the incisors and premolars.

  4. Tooth sensitivity can be a sign of a more serious dental problem, such as a cracked tooth or gum disease.

  5. Teeth sensitivity can also be caused by certain medical conditions, such as acid reflux or bulimia.

  6. Braces can cause thinning of enamel or gumline when you aren’t cleaning thoroughly enough around the brackets, and particularly around the back molars. Other signs that you may not be brushing well enough include bad breath, bleeding gums or unexplained tooth pain.
