What Causes Tooth Sensitivity and How to Fix It – A Guide from Your Oxfordshire Green Dentist

Do you wince when sipping a hot drink or biting into ice cream? If so, you’re not alone. Tooth sensitivity is one of the most common dental complaints we see at John Miller Dental Practice & Implants in Oxfordshire But what causes it-and more importantly, how can you fix it?

Let’s break it down.

What Is Tooth Sensitivity?

Tooth sensitivity, or “dentin hypersensitivity”, occurs when the protective enamel on your teeth wears down or your gums recede, exposing the softer dentin layer underneath. This layer contains microscopic tubules that lead to the nerves of your teeth, making them more reactive to temperature changes, pressure, and even sweet or acidic foods.

Common Causes of Tooth Sensitivity

At our Oxford dental clinic, these are the most frequent causes we identify:

1. Brushing Too Hard
   Aggressive brushing or using a hard-bristled toothbrush can wear down enamel and cause gum recession.
2. Tooth Decay or Cavities
   Untreated decay exposes dentin, which increases sensitivity.
3. Gum Disease (Periodontitis)
   Inflammation can lead to gum recession, exposing the roots of your teeth.
4. Teeth Grinding (Bruxism)
   Grinding or clenching can erode enamel and expose nerves.
5. Acidic Foods and Drinks
   Frequent consumption of citrus, wine, or fizzy drinks can erode enamel over time.
6. Recent Dental Treatments
   Procedures like fillings, whitening, or crowns can temporarily increase sensitivity.

How to Treat Tooth Sensitivity

At John Miller Dental Practice, we tailor treatment based on the cause. Here are the most effective options:

1. 🪥 Use Desensitising Toothpaste
   Switch to a toothpaste designed for sensitive teeth, such as Sensodyne. These contain compounds that block nerve signals.
2. 🦷 Apply Fluoride Treatments
   We offer in-clinic fluoride gels or varnishes in Oxfordshire to strengthen enamel and reduce discomfort.
3. 🧼 Practice Gentle Brushing
   Use a soft-bristled toothbrush and gentle, circular motions. Avoid whitening toothpaste unless recommended.
4. 🛑 Avoid Acidic and Sugary Foods
   Cut down on citrus, fizzy drinks, and sugary snacks that can wear enamel.
5. 🛏️ Wear a Night Guard
   If grinding is the issue, we can custom-make a night guard to protect your teeth while you sleep.
6. 👨‍⚕️ Address Underlying Conditions
   In cases involving decay, gum disease, or exposed tooth roots, we may recommend a filling, gum treatment, or even a root canal for severe cases.
