Tooth Sensitivity: What Causes It and How to Find Relief

Solutions for the Zing That Disrupts Your Smile

Do you ever wince when sipping a hot coffee or biting into ice cream? That sudden jolt of discomfort might be more than just a fleeting annoyance—it could be a sign of tooth sensitivity, a common dental issue affecting millions of people.

At Hart Family Dentistry in Marietta, GA, we’re here to help you understand what’s behind that sharp pain—and what you can do to stop it.

What Is Tooth Sensitivity?

Tooth sensitivity (also called dentin hypersensitivity) happens when the outer layer of your tooth, called enamel, becomes worn or damaged—exposing the sensitive dentin underneath. This inner layer is filled with tiny tubules that lead to the nerve. When triggered by heat, cold, sweets, or acidic foods, those tubules can send pain signals straight to the nerve, causing that familiar zing.

Common Causes of Sensitivity

A variety of habits and conditions can wear down enamel or expose sensitive areas:

  • Brushing Too Hard: Using a hard-bristled brush or brushing with too much force can erode enamel over time.
  • Gum Recession: When your gums pull away from the tooth (often due to gum disease or overbrushing), they expose the unprotected roots.
  • Teeth Grinding (Bruxism): Grinding or clenching wears down enamel and can cause tiny cracks that increase sensitivity.
  • Acidic Foods and Drinks: Frequent exposure to citrus fruits, soda, vinegar, and wine can weaken enamel and trigger discomfort.
  • Recent Dental Work: Procedures like fillings, crowns, or whitening treatments can cause temporary sensitivity. This usually fades within a few days.

How to Reduce Tooth Sensitivity

The good news? Sensitivity is highly manageable with a few simple changes and professional care. Here’s what we recommend:

  • Switch to a Desensitizing Toothpaste: These formulas help block nerve signals and can significantly reduce pain over time.
  • Use a Soft-Bristled Toothbrush: Gentle brushing helps preserve enamel and prevent gum irritation.
  • Limit Acidic Foods and Rinse with Water: Reducing acid exposure and rinsing your mouth after meals helps protect enamel from erosion.
  • Consider a Custom Night Guard: If you grind your teeth at night, a professionally made guard can prevent further enamel wear.

Ask About In-Office Treatments

We offer solutions like fluoride varnishes, bonding agents, or gum treatments to help strengthen teeth and reduce sensitivity.

When to See Dr. Hart

Occasional twinges are common, but persistent or severe tooth sensitivity can signal deeper issues like cavities, cracked teeth, or gum disease. If you’re experiencing discomfort regularly, don’t wait—schedule a visit so we can identify the cause and create a personalized treatment plan.
