Tooth Sensitivity: 4 Causes and 3 Easy Solutions


Do you ever feel a sharp, shooting pain when biting into something too cold or too hot? If so, you may be experiencing tooth sensitivity. Tooth sensitivity is a common dental issue that can occur in people of any age and can cause considerable discomfort. Knowing the causes and solutions of sensitive teeth can help you treat them quickly and accurately. Here, we’ll discuss four common causes and three easy solutions for tooth sensitivity.

One of the most common causes of tooth sensitivity is exposed dentin. Dentin is a layer of tissue located just beneath the enamel, the hard protective outer layer of your teeth. If this layer becomes exposed due to gum recession or erosion, it can lead to an uncomfortable sensation when coming into contact with hot and cold temperatures.

Another common cause of tooth sensitivity is gum disease. This occurs when plaque builds up on the teeth and causes infection in the gums. If left untreated, it can lead to recession of the gums and, ultimately, exposed dentin.

Damaged enamel is also a potential cause of sensitive teeth. This can occur from excessive brushing or acidic foods and drinks. Enamel erosion can cause the dentin to become exposed and create sensitivity when eating.

Finally, tooth decay is another possible source of tooth sensitivity. Decay weakens the enamel, which can lead to pain when biting down on certain foods or drinking cold beverages.


4 Causes of Tooth Sensitivity

  1. Abrasion: Abrasions occur when the enamel is worn away due to brushing with too much force or using a hard-bristled toothbrush over time. This exposes the roots of the teeth, increasing their sensitivity.
  2. Gum Recession: This is when the gums pull away from the teeth, allowing bacteria to get into the further reach of the tooth root and cause irritation.
  3. Tooth Decay: If a cavity has not been treated, it can lead to exposed dentin and cause an increase in sensitivity.
  4. Acidic Foods: Citrus fruits and acidic juices can cause the enamel to wear away over time, leading to tooth sensitivity.

3 Easy Solutions for Tooth Sensitivity

  1. Use a Soft-Bristled Toothbrush: Using a soft-bristled brush helps minimize abrasions and irritation of the gums.
  2. Flouride Toothpaste: A toothpaste with fluoride can help protect the enamel and reduce sensitivity over time.
  3. Desensitizing Products: There are a variety of desensitizing products on the market designed to fill in microscopic openings and block off nerve endings, helping to reduce tooth sensitivity.


Tooth sensitivity is a common issue that can lead to significant discomfort. Knowing the causes and solutions of sensitive teeth can help you manage your symptoms effectively and easily. With proper care and attention, you can keep your mouth healthy, happy, and pain-free!
