Understanding Dental Sensitivity: Causes, Symptoms, and Solutions

Dental sensitivity, or tooth sensitivity, is a prevalent issue that many people encounter at some point in their lives. It can manifest as a transient discomfort or a persistent problem that necessitates attention. At Monread Dental, we recognise the impact that sensitivity can have on your day-to-day life and oral health. In this blog post, we will delve into the causes, symptoms, and solutions for dental sensitivity.

Causes of Dental Sensitivity:

  1. Enamel Erosion: The outer layer of your teeth, known as enamel, shields the underlying dentin and nerves. When enamel wears away due to factors such as acidic foods, vigorous brushing, or teeth grinding, it exposes the dentin, resulting in sensitivity.

  2. Gum Recession: Receding gums expose the sensitive tooth roots. This can occur due to gum disease, improper brushing techniques, or ageing. Exposed roots are more susceptible to sensitivity, particularly to hot and cold temperatures.

  3. Tooth Decay: Cavities can lead to sensitivity as they progress and reach the inner layers of the tooth, where nerves are located.

  4. Cracked Teeth: Hairline cracks in teeth can permit external stimuli to reach the nerves, causing sensitivity. This can result from trauma, teeth grinding, or biting hard objects.

Symptoms of Dental Sensitivity:

  • Sharp, shooting pain when consuming hot or cold foods and beverages.

  • Discomfort when eating sugary or acidic foods.

  • Pain when brushing or flossing teeth, especially along the gumline.

  • Lingering pain after exposure to triggers like temperature changes.

Solutions for Dental Sensitivity:

  1. Desensitising Toothpaste: Specialised toothpaste containing ingredients like potassium nitrate or strontium chloride can help block the transmission of pain signals from the tooth surface to the nerve.

  2. Fluoride Treatment: Professional fluoride applications can strengthen enamel and reduce sensitivity. This treatment is often recommended for patients with enamel erosion.

  3. Dental Sealants: Applying dental sealants can help protect exposed tooth surfaces and reduce sensitivity.

  4. Proper Oral Hygiene: Maintaining good oral hygiene practices, such as using a soft-bristle toothbrush and avoiding aggressive brushing, can prevent enamel erosion and gum recession.

  5. Mouthguards: For those who grind their teeth, a custom-fitted mouthguard can prevent further damage and reduce sensitivity.

  6. Dietary Changes: Limiting the consumption of acidic and sugary foods can prevent enamel erosion and decay, addressing the root causes of sensitivity.

  7. Professional Dental Treatment: In some cases, dental procedures such as fillings, crowns, or bonding may be recommended to address underlying issues causing sensitivity.
