What Causes Sensitive Teeth and How Can I Treat It?

Tooth sensitivity can be caused by various factors including enamel erosion, gum recession, or cavities. Discover the causes and effective treatments.

Understanding Tooth Sensitivity

If you've ever winced at the thought of biting into ice cream or sipping hot coffee, you're not alone. Tooth sensitivity affects millions of people and can range from a mild twinge to severe discomfort that disrupts daily life.

What Causes Sensitive Teeth?

Tooth sensitivity occurs when the underlying layer of your teeth (dentin) becomes exposed. This can happen due to:

Enamel Erosion

  • Acidic foods and drinks - Citrus fruits, fizzy drinks, and wine can erode enamel over time
  • Acid reflux - Stomach acids reaching the mouth can damage enamel
  • Brushing too hard - Aggressive brushing wears away protective enamel
  • Teeth grinding - Clenching and grinding can wear down tooth surfaces

    • Gum Recession

    When gums pull back from teeth, the sensitive root surface becomes exposed. This can be caused by:

  • Gum disease (periodontitis)
  • Brushing too aggressively

    • Other Causes

  • Cavities - Decay creates holes that expose sensitive inner layers
  • Cracked teeth - Fractures can reach the nerve
  • Worn fillings - Old restorations may not protect as well as they once did
  • Recent dental work - Temporary sensitivity after fillings or crowns is normal

    • Symptoms to Watch For

    Sensitivity typically occurs with:

  • Alcohol-based mouthwashes

    • Treatment Options

    The good news is that sensitive teeth can usually be treated effectively:

    At-Home Remedies

  • Desensitising toothpaste - Contains compounds that block pain signals
  • Soft-bristled toothbrush - Gentler on enamel and gums
  • Proper brushing technique - Gentle, circular motions rather than harsh scrubbing
  • Fluoride mouthwash - Helps strengthen enamel

    • Professional Treatments

    At Buxton Dental, we offer several solutions for persistent sensitivity:

  • Fluoride varnish - Applied to sensitive areas to strengthen enamel
  • Dental bonding - Covers exposed root surfaces
  • Gum grafts - Replaces lost gum tissue to cover exposed roots
  • Root canal - For severe cases where other treatments haven't worked

    • Prevention Tips

    Protect your teeth from becoming sensitive:

  • Use a soft toothbrush and replace it every 3-4 months
  • Brush gently - Let the bristles do the work
  • Limit acidic foods and wait 30 minutes after eating them before brushing
  • Wear a night guard if you grind your teeth
  • Maintain regular dental check-ups - We can spot problems early

    • When to See a Dentist

    While mild sensitivity is common, you should book an appointment if:

  • Sensitivity persists for more than a week
  • The pain is severe or keeps you awake
  • You notice other symptoms like swelling or bleeding
  • Sensitivity affects your daily life
