Understanding Tooth Sensitivity

Have you ever experienced a sudden, sharp pain in your teeth when drinking cold water? If so, you’re not alone. This common phenomenon is known as tooth sensitivity, and it affects many people worldwide.

What is Tooth Sensitivity?

Tooth sensitivity, also known as dentin hypersensitivity, is a common dental condition characterized by discomfort or pain in the teeth when encountering certain substances or temperatures. It can be a temporary issue or a chronic problem, and it can affect one tooth or several teeth.

Dentin hypersensitivity occurs when the dentin – the layer beneath the tooth’s hard surface (enamel) – becomes exposed. This exposure can lead to discomfort or pain when eating or drinking certain foods, particularly hot or cold ones. For more detailed information, you can check out this resource.

Causes of Tooth Sensitivity

There are several causes of tooth sensitivity:

  • Enamel erosion: The enamel is the hard, protective layer that covers your teeth. When the enamel wears down, it can expose the dentin, leading to sensitivity. Acidic foods and drinks, poor dental hygiene, and certain medical conditions can cause enamel erosion.
  • Gum recession: This occurs when the gum tissue that surrounds the teeth wears away or pulls back, exposing more of the tooth or the tooth’s root. This exposure can lead to sensitivity.
  • Tooth decay: Also known as cavities, tooth decay can cause sensitivity. When a tooth decays, it can create holes in the tooth, which can reach the dentin and cause pain.
  • Tooth grinding and clenching: These habits can wear down the enamel and lead to sensitivity. Many people grind or clench their teeth in their sleep without realizing it, which can lead to this issue over time.

How Cold Water Affects Sensitive Teeth

When you drink cold water, the temperature change can cause the fluid within tiny tubes located in the dentin to move, causing a nerve in the tooth to react with a sharp, short pain. This is why your teeth might hurt when you drink cold water.

The pain is essentially a warning from your nerves that something is wrong. If you’re experiencing this kind of pain regularly, it’s important to seek advice from a dental professional. They can help identify the cause of your sensitivity and suggest appropriate treatments. For more information on how to deal with tooth sensitivity, you can visit this link.


How to Deal with Tooth Sensitivity

If you’re dealing with tooth sensitivity, there are several ways you can manage it:

  • Special toothpaste: There are toothpastes specifically designed for sensitive teeth. These toothpastes contain compounds that help block the transmission of pain signals from the tooth surface to the nerve.
  • Changing brushing habits: Brushing too hard or using a hard-bristled toothbrush can cause enamel erosion and gum recession, leading to sensitivity. Switch to a soft-bristled toothbrush and brush gently to help alleviate the issue.

Treatment Options for Tooth Sensitivity

If home remedies aren’t enough to manage your tooth sensitivity, it might be time to seek professional help. Here are some treatments your dentist might recommend:

  • Fillings: If your sensitivity is due to cavities, your dentist might recommend fillings to cover the exposed dentin.
  • Fluoride gel: This is a technique used by dentists to strengthen tooth enamel and reduce the transmission of sensations.
  • Surgical gum graft: If your tooth root has lost gum tissue, a small amount of gum tissue can be taken from elsewhere in your mouth and attached to the affected site. This can protect exposed roots and reduce sensitivity.

Prevention of Tooth Sensitivity

Prevention is always better than cure. Here are some preventive measures you can take:

  • Proper oral hygiene: Brushing and flossing regularly can help maintain good oral health and prevent conditions that contribute to sensitivity.
  • Diet: Acidic foods and drinks can cause enamel erosion. Try to limit your intake of these items to protect your teeth.
  • Regular dental check-ups: Regular visits to the dentist can help detect and treat oral health issues early before they lead to sensitivity.


  • Can tooth sensitivity go away? Yes, tooth sensitivity can sometimes go away on its own, especially if it’s due to a temporary cause like a tooth whitening procedure. However, if the sensitivity is due to an underlying dental issue, it won’t go away until the issue is addressed.
  • Why are my teeth sensitive to cold but not hot? Teeth can be sensitive to any extreme temperatures. However, cold sensitivity is more common because cold substances can cause the fluid in the dentinal tubules to move, triggering a pain response from the nerves in your teeth.
