Sensitivity Struggles: What Causes Tooth Sensitivity and How to Find Relief


Last Modified: July 17, 2023


Tooth sensitivity can be a painful and bothersome condition that affects many people. It occurs when the tooth enamel wears down, exposing the underlying dentin and nerve endings, resulting in sensitivity to hot, cold, sweet, or acidic foods and beverages. In this blog post, we will explore the causes of tooth sensitivity and provide tips on finding relief for this common dental issue.

Causes of Tooth Sensitivity

  • Enamel erosion: The outer layer of the tooth, known as enamel, can gradually wear away due to factors such as aggressive brushing, acidic foods and drinks, or tooth grinding. When the enamel thins, it exposes the sensitive dentin layer beneath, leading to tooth sensitivity.
  • Gum recession: Gum disease or improper brushing techniques can cause the gums to recede, exposing the tooth roots. Since the roots lack a protective layer of enamel, they are more susceptible to sensitivity.
  • Tooth decay: Cavities can form on the surface of teeth, causing sensitivity when the decay reaches the inner layers of the tooth, including the dentin and nerve endings.
  • Cracked or fractured teeth: When a tooth is cracked or fractured, it can create pathways for sensitivity-inducing substances to reach the nerve endings inside the tooth.

Finding Relief from Tooth Sensitivity

  • Switch to a soft-bristled toothbrush: Brushing with a hard-bristled toothbrush or applying excessive pressure can contribute to enamel erosion and gum recession. Switching to a soft-bristled brush and using gentle circular motions can help prevent further damage.
  • Use desensitizing toothpaste: Special toothpaste formulated for sensitive teeth can help alleviate discomfort. These toothpaste brands contain ingredients like potassium nitrate or strontium chloride that help block the nerve endings, reducing sensitivity over time.
  • Practice proper oral hygiene: Maintaining good oral hygiene is crucial for preventing and managing tooth sensitivity. Brush your teeth at least twice a day with fluoride toothpaste and floss daily to remove plaque and prevent gum disease.
  • Avoid acidic and abrasive substances: Acidic foods and drinks, such as citrus fruits, sodas, and sports drinks, can erode enamel. Similarly, abrasive substances like tooth whitening products or hard candies can contribute to sensitivity. Limiting your exposure to these substances can help protect your teeth.
  • Limit teeth grinding: If you grind your teeth, especially during sleep, it’s important to address this issue. Teeth grinding can lead to enamel erosion and tooth fractures, causing sensitivity. Your dentist may recommend a mouthguard or other treatments to reduce grinding.
  • Visit your dentist regularly: Regular dental check-ups are essential for identifying and addressing tooth sensitivity. Your dentist can perform a thorough examination, address any underlying issues, and provide professional treatments such as fluoride varnishes or dental sealants to reduce sensitivity.
  • Modify your diet: Incorporate foods rich in calcium, phosphorus, and vitamin D to promote strong teeth and enamel. Additionally, avoid extreme temperature changes while eating or drinking, as they can trigger sensitivity.
  • Consider dental procedures: In severe cases, your dentist may recommend procedures to treat tooth sensitivity. These may include dental bonding, gum grafting to cover exposed roots, or applying dental sealants to protect sensitive areas.


Tooth sensitivity can significantly impact your daily life, causing discomfort and restricting your food choices. By understanding the causes and following the tips outlined in this blog post, you can find relief from tooth sensitivity. Remember, maintaining good oral hygiene, using desensitizing toothpaste, and seeking professional dental care are key to managing and preventing tooth sensitivity. Prioritize your dental health, and consult with your dentist for personalized guidance and treatment options.
