What Causes Tooth Sensitivity and How to Treat It

Understand the Causes of Tooth Sensitivity

Best Family Dentistry in Pennsauken, NJ

Tooth sensitivity is more than a minor inconvenience—it’s a daily discomfort that can interfere with everything from your morning coffee to your favorite desserts. If you’ve ever felt a sharp, sudden pain when consuming something hot, cold, sweet, or acidic, you may be dealing with dentin hypersensitivity, commonly known as tooth sensitivity.

At Pennsauken Family Dental in Pennsauken, NJ, we understand how frustrating this condition can be, and we’re committed to helping our patients find lasting relief through modern, customized treatments.

What Is Tooth Sensitivity?

Tooth sensitivity occurs when the inner layer of your tooth, known as dentin, becomes exposed. This can happen due to worn enamel or gum recession, leaving the tiny tubules within the dentin vulnerable to external triggers like temperature changes or sugar.

These triggers send pain signals to the nerves inside your teeth, causing everything from mild discomfort to intense pain.

Common Causes of Tooth Sensitivity

  1. Enamel Erosion
    Enamel can wear away due to overbrushing, acidic foods and drinks, or acid reflux. When this protective layer thins, it exposes the dentin underneath.
  2. Gum Recession
    Aging, gum disease, or improper brushing techniques can cause gums to pull away from the teeth, revealing sensitive root surfaces.
  3. Tooth Decay or Damaged Fillings
    Cavities, cracked teeth, or old dental work can expose the inner structures of the tooth, leading to sensitivity.
  4. Teeth Grinding (Bruxism)
    Constant grinding can wear down the enamel and create microcracks, exposing the nerves and causing discomfort.
  5. Recent Dental Procedures
    After procedures like teeth whitening, fillings, or restorations, it’s common to experience temporary sensitivity.

Diagnosing Tooth Sensitivity at Pennsauken Family Dental

When you visit us, we start with a thorough evaluation of your dental health, including:

  • Reviewing your symptoms and lifestyle habits
  • Examining your teeth and gums
  • Taking digital X-rays if needed
  • Identifying worn enamel, receding gums, or other structural issues

Once we understand the root cause, we’ll design a treatment plan that works specifically for your situation.

How We Treat Tooth Sensitivity

  1. Desensitizing Toothpaste
    Special formulations can help block nerve responses and reduce pain over time. These are a good first step for mild cases.
  2. Fluoride Treatments
    In-office fluoride applications strengthen enamel and can reduce discomfort from exposed dentin.
  3. Dental Bonding
    A protective coating can be applied to exposed root surfaces to seal the tubules and reduce sensitivity.
  4. Gum Grafting
    If gum recession is the cause, a graft may help restore lost gum tissue and cover exposed areas.
  5. Root Canal Therapy
    If the sensitivity is severe and due to infection or nerve exposure, a root canal may be necessary to eliminate pain.

Preventing Tooth Sensitivity

  • Use a soft-bristled toothbrush and brush gently
  • Avoid acidic foods and beverages
  • Wear a nightguard if you grind your teeth
  • Maintain regular dental cleanings and exams
