Do you ever flinch when eating ice cream or sipping hot coffee? You’re not alone. Tooth sensitivity is one of the most common dental complaints we hear at Pecan Tree Family Dentistry—and thankfully, it’s often simple to treat.

🧊 What Causes Sensitive Teeth?

Tooth sensitivity occurs when the protective enamel wears down or when gum recession exposes the tooth’s root. This allows hot, cold, sweet, or acidic stimuli to reach the nerve more easily.

Common causes include:

  • Brushing too hard or using a hard-bristled toothbrush
  • Gum recession from aging or gum disease
  • Tooth grinding (bruxism)
  • Tooth decay or damaged fillings
  • Whitening products—especially over-the-counter gels or strips
  • Acidic foods and beverages like soda, citrus, or vinegar

🩺 When to See a Dentist

Some mild sensitivity is normal, but if you experience:

  • Sharp, persistent pain
  • Discomfort that affects eating or drinking
  • Pain that lingers even without triggers

…then it’s time to schedule a dental exam. Sensitivity can be a symptom of:

  • Cavities
  • Cracked or fractured teeth
  • Worn dental restorations
  • Gum disease

At Pecan Tree Family Dentistry, we’ll determine the root cause and develop a customized plan for relief.

✅ How to Treat Tooth Sensitivity

The good news? Many cases of sensitivity respond to simple, conservative treatments:

  • Use desensitizing toothpaste (like Sensodyne®)
  • Switch to a soft-bristled toothbrush and brush gently
  • Limit acidic foods and rinse with water afterward
  • Apply fluoride gel or varnish to strengthen enamel
  • Use a custom nightguard if grinding is an issue
  • Repair damaged teeth with fillings, crowns, or other restorations
