5 Common Causes of Tooth Sensitivity

That sharp, sudden twinge of pain when your teeth get exposed to hot, cold, sweet, or acidic foods can be jarring. This reaction is tooth sensitivity, or dentin hypersensitivity. Dr. Ginger Rome, Dr. Maurina Brooks, and our team at The Dentists at North Cypress in Houston, Texas, are here to explain what might be causing your discomfort and how we can help.

Tooth sensitivity occurs when the protective outer layer of your teeth (enamel) wears down, or your gums recede, exposing the softer layer underneath called dentin. This dentin contains tiny tubes that lead directly to the tooth's nerve. When triggers like temperature or sweetness reach these tubes, you feel that characteristic sharp pain.

Understanding the culprits behind sensitive teeth

Here are five of the most common reasons you might be experiencing tooth sensitivity:

1. Worn-down enamel

Your tooth enamel is the strongest substance in your body, but it’s not invincible. Aggressive brushing with a hard-bristle toothbrush or using abrasive toothpaste can wear it down over time. A diet high in acidic foods and drinks, like citrus fruits, sodas, and wine, can also erode enamel, leaving the sensitive dentin exposed.

2. Gum recession

Your gums play a crucial role in protecting the roots of your teeth; enamel does not cover them.  If your gums start to pull away from your teeth, a condition known as gum recession, these sensitive roots become exposed. Gum disease is a primary cause of recession, which is why we emphasize preventive care and offer periodontal treatments to keep your gums healthy.

3. Teeth grinding

Many people grind or clench their teeth, often without realizing it, especially during sleep. This condition, known as bruxism, places immense pressure on your teeth, which can wear down the enamel and lead to tooth sensitivity. If we suspect you’re grinding your teeth, Dr. Rome or Dr. Brooks may recommend a custom-fitted mouthguard to protect your teeth at night.

4. A cracked or chipped tooth

A crack or chip in your tooth, no matter how small, can be enough to expose the underlying dentin. These cracks can also allow bacteria to enter the tooth, leading to nerve irritation and further sensitivity or pain. It's critical to have any damage to your teeth evaluated promptly to prevent more serious issues.

5. Tooth decay or a new filling

A cavity is a hole in your tooth caused by decay, which directly exposes the sensitive inner parts of the tooth. Additionally, it’s common to experience temporary sensitivity after a dental procedure, such as a filling or a crown. This type of sensitivity usually resolves on its own within a few weeks. If it persists, please let us know.
