What Causes Tooth Sensitivity—and How to Treat It

Sharp pain when eating or drinking? Tooth sensitivity is common, but it’s also treatable with the right care.

Why Do Teeth Become Sensitive?

Tooth sensitivity occurs when the protective layers of your teeth wear down, exposing the inner dentin. This layer contains tiny tubules that connect directly to the tooth’s nerve, making your teeth more reactive to hot, cold, sweet, or acidic foods.

At Mark Bilello DDS, we help patients identify the cause of sensitivity and provide targeted solutions to restore comfort.

Common Causes of Tooth Sensitivity

Several factors can lead to sensitive teeth:

  • Enamel erosion from acidic foods and drinks
  • Gum recession exposing tooth roots
  • Tooth decay or cavities
  • Cracked or chipped teeth
  • Aggressive brushing or using a hard-bristled toothbrush
  • Teeth grinding (bruxism)

Routine visits through our general and restorative dentistry services help detect these issues early.

When Sensitivity Signals a Bigger Problem

Occasional sensitivity is common, but persistent or severe discomfort may indicate:

  • A cavity requiring treatment
  • Advanced gum disease
  • A cracked tooth
  • Worn dental restorations

Ignoring these symptoms can lead to more serious problems that require extensive treatment.

How Tooth Sensitivity Is Treated

Treatment depends on the underlying cause:

  • Desensitizing toothpaste to block nerve signals
  • Fluoride treatments to strengthen enamel
  • Dental bonding or sealants to protect exposed areas
  • Gum treatments for recession
  • Nightguards for teeth grinding

Comfort-focused care is available through our patient comfort services to ensure a relaxed experience.

Simple Ways to Reduce Sensitivity at Home

You can minimize sensitivity with a few daily changes:

  • Use a soft-bristled toothbrush
  • Avoid overly acidic foods and drinks
  • Brush gently using proper technique
  • Use toothpaste designed for sensitive teeth
  • Wear a nightguard if you grind your teeth

For families, teaching proper brushing habits early is essential. Preventive guidance is part of our approach to family dentistry.

When to See a Dentist

If sensitivity lasts more than a few days or worsens over time, it’s time for a professional evaluation. Early treatment prevents further damage and restores comfort quickly.
