Ever Wonder Why Your Teeth Are So Sensitive?

July 31, 2024

Tooth sensitivity is a common dental issue that can cause discomfort or pain when eating or drinking hot, cold, sweet, or acidic foods and beverages. Understanding the underlying causes can help you manage and prevent this condition.


Some of the top reasons for sensitivity that we see in the practice include:


  • Enamel Erosion: The enamel is the hard, protective outer layer of the teeth. It can wear down over time due to acidic foods and drinks, aggressive brushing, or teeth grinding (bruxism). When the enamel erodes, it exposes the underlying dentin, which is more sensitive to external stimuli.
  • Gum Recession: Gum recession occurs when the gum tissue surrounding the teeth pulls back or wears away, exposing the tooth roots. The roots do not have protective enamel, making them more vulnerable to sensitivity.
  • Tooth Decay: Cavities and tooth decay can create holes or cracks in the enamel, exposing the dentin and causing sensitivity.
  • Cracked or Chipped Teeth: Damage to the teeth, such as cracks or chips, can expose the dentin or the inner pulp, leading to sensitivity.
  • Recent Dental Procedures: Some dental treatments, such as fillings, crowns, or teeth whitening, can cause temporary tooth sensitivity.

Effective Treatments and Preventive Measures

Managing tooth sensitivity involves a combination of treatments and preventive strategies to protect your teeth and reduce discomfort. If you experience frequent sensitivity, you may want to consider one (or a few) of the following.


  • Desensitising Toothpaste: Using toothpaste designed for sensitive teeth can help block the transmission of pain signals from the tooth surface to the nerve. Look for products with ingredients like potassium nitrate or stannous fluoride.
  • Fluoride Treatments: Our team can apply fluoride gel or varnish to the sensitive areas of your teeth to strengthen enamel and reduce sensitivity. At-home fluoride treatments may also be recommended.
  • Proper Oral Hygiene: Maintaining good oral hygiene is crucial. Use a soft-bristled toothbrush and gentle brushing techniques to avoid damaging the enamel and gums. Floss daily to remove plaque and food particles.
  • Dietary Changes: Limit the consumption of acidic foods and drinks, such as citrus fruits, sodas, and wine, which can erode enamel. Rinse your mouth with water after consuming acidic substances to neutralise acids.
  • Mouthguards: If you grind your teeth at night, a custom-fitted mouthguard can protect your teeth from damage and reduce sensitivity.
  • Dental Treatments: For severe sensitivity caused by decay or damage, our team may recommend treatments such as fillings, crowns, inlays, or bonding to cover exposed dentin and protect the tooth.
  • Gum Grafting: If gum recession is the cause of sensitivity, a gum graft procedure can cover the exposed roots and reduce discomfort.


If you experience persistent or severe sensitivity, schedule an appointment to discuss your symptoms and receive personalised treatment with our team.

Lemon water first thing in the morning. Sparkling water throughout the day. A kombucha with lunch. These feel like healthy habits, and some of them genuinely are. But there's a side effect most people don't hear much about: what all that acidity is quietly doing to your tooth enamel. It's one of those things that happens slowly enough that you don't notice it, but eventually becomes impossible to ignore.
