Sensitive Teeth: Causes, Relief and Expert Tips from Your Cambridge Dentist

Many people experience sharp or sudden discomfort when consuming cold foods, hot drinks, sweet treats or even just cold air. Sensitive teeth are a common problem and can affect your daily comfort — but there’s good news: with the right care, you can often reduce sensitivity and protect your smile.

At Dentistry & More in Cambridge, we help patients understand the causes of sensitivity and recommend effective, long-term solutions.

What Causes Tooth Sensitivity?

Tooth sensitivity occurs when the protective enamel wears thin or when gums recede, exposing the dentine layer underneath. Dentine contains microscopic tubules that connect to the nerve of the tooth, so stimuli (such as hot, cold, sweet or acidic foods) can trigger pain.

Common triggers include:

  • Brushing too hard or using a hard-bristled toothbrush
  • Gum recession
  • Acidic foods and drinks
  • Teeth grinding (bruxism)
  • Tooth decay, cracked teeth or exposed roots
  • Recent dental treatments (usually temporary)
Top Tips to Reduce Tooth Sensitivity

Here are practical, dentist-recommended ways to ease sensitivity and protect your teeth:

  1. Use a Toothpaste for Sensitive Teeth
    Switch to a desensitising toothpaste designed for sensitive teeth. These help block the pathways that send sensations from your tooth surface to the nerve. You’ll often see improvement over a few weeks with regular use.
  2. Brush Gently with a Soft Toothbrush
    Brush twice a day using light pressure and gentle, circular motions. Hard brushing wears enamel and can worsen sensitivity.
  3. Avoid Highly Acidic Foods and Drinks
    Acidic drinks (like fizzy drinks, fruit juices or wine) and foods can erode enamel over time. Try to reduce how often you have these, and rinse your mouth with water after enjoying them.
  4. Give Your Teeth a Break After Acidic Meals
    If you’ve eaten something acidic, wait at least 30 minutes before brushing. Immediately brushing can further wear enamel that’s been softened by acid.
  5. Use a Fluoride Mouthwash or Gel
    Fluoride helps to strengthen enamel and reduce sensitivity. Your dentist may recommend a daily fluoride rinse or a professional fluoride application during appointments.
  6. Treat Teeth Grinding
    If you clench or grind your teeth, especially at night, ask us about a custom mouthguard. This protects enamel from wear and helps reduce sensitivity.
When Should You See a Dentist?

If sensitivity is persistent, only affects one tooth, arises after trauma, or is accompanied by swelling, bleeding or pain when biting, it’s important to book an appointment. These could indicate underlying problems such as decay, gum disease or a cracked tooth.

At Dentistry & More, we offer tailored assessments and treatments, including:

  • Professional desensitising applications
  • Fluoride varnish treatments
  • Dental bonding to protect exposed roots
  • Gum health evaluation and treatments
