How to Stop Teeth Sensitivity Immediately?

Teeth sensitivity, or dentin hypersensitivity, is a common dental problem. People experience discomfort or pain when they eat, drink, or breathe something hot or cold or sweet or sour. Sometimes, even a burst of cold air can make sensitive teeth twinge. This pain can be sharp and sudden, but it’s usually temporary.

The reason behind teeth sensitivity lies in the structure of our teeth. Underneath the tooth’s protective outer enamel layer is a porous layer called dentin. The dentin becomes exposed when the enamel gets worn down or the gums recede. This layer contains tiny, fluid-filled tubes that lead to the tooth’s nerve center, or pulp. When heat, cold, or pressure touches these tubes, it triggers the nerves, resulting in pain.

Tooth sensitivity can affect one or more teeth. It’s most common in people aged between 20 and 50. While it’s a common problem, you don’t have to live with the pain. Many at-home remedies and professional dental treatments are available to help relieve the sting of sensitive teeth.

Causes of Teeth Sensitivity

Several factors can contribute to the development of tooth sensitivity. Here are the most common:

  1. Tooth Erosion: The consumption of acidic foods and beverages, such as citrus fruits and soda, can erode tooth enamel over time and expose the dentin.
  2. Tooth Decay: Cavities and decay can cause tooth sensitivity, particularly when the decay is near the gum line.
  3. Gum Recession: This occurs when the gums pull away from the teeth, exposing the root surfaces. These surfaces don’t have a protective enamel layer, which can lead to sensitivity.
  4. Periodontal Disease: Gum disease can lead to sensitivity by causing gum recession and inflammation, both exposing the dentin and teeth’ roots.
  5. Tooth Grinding: Grinding or clenching your teeth can wear down the enamel and expose the underlying dentin, causing sensitivity.
  6. Tooth Whitening Products: Many tooth whitening products contain harsh chemicals that can lead to tooth sensitivity.
  7. Dental Procedures: Teeth may become temporarily sensitive after certain dental procedures, such as professional cleanings, root planing, crown placement, and tooth restoration. This type of sensitivity usually resolves within four to six weeks.
  8. Cracked Teeth: A cracked or chipped tooth can cause pain that goes beyond tooth sensitivity. If the crack extends down to the root, eating or drinking can cause intense pain.

Sensitive Teeth Symptoms

Tooth sensitivity, also known as dentin hypersensitivity, typically manifests as a sudden, sharp flash of pain when the teeth encounter triggers such as hot, cold, sweet, or acidic foods and drinks. The following are common symptoms associated with sensitive teeth:

  1. Sharp, Sudden Pain: This is the most common symptom of sensitive teeth. You might experience a sudden, sharp flash of pain in response to certain triggers. The pain usually subsides once the trigger is removed.
  2. Pain When Brushing or Flossing: If you experience discomfort or pain when brushing or flossing your teeth, this could be a sign of tooth sensitivity.
  3. Discomfort When Eating or Drinking Certain Foods and Beverages: Sensitivity can cause discomfort when consuming hot, cold, sweet, or acidic foods and drinks. Even breathing in cold air can trigger sensitivity pain in some people.
  4. Pain When Consuming Cold Drinks or Ice Cream: The nerves within your teeth can be particularly sensitive to cold temperatures, causing pain when you consume cold items.
  5. Pain From Sweet Foods and Drinks: Sweets can also cause a sharp, sudden pain if you have sensitive teeth.
  6. Discomfort or Pain When Eating Acidic Foods: Foods and drinks that are high in acid, such as citrus fruits, tomatoes, pickles, and fresh fruit juice, can cause discomfort or pain in people with sensitive teeth.

Why Are Sensitive Teeth So Painful?

Sensitive teeth are painful because the protective layers of the teeth have been worn down, exposing the dentin or, in severe cases, the tooth’s nerve. Let’s take a closer look at why this leads to pain.

The tooth is made up of several layers. The outermost layer, the enamel, is the hardest and acts as a protective shield for the rest of the tooth. Underneath the enamel is the dentin, which is not as hard and contains tiny tubules that lead to the nerve center of the tooth, known as the pulp.

When the enamel is eroded, or the gum line has receded to expose the roots of the teeth (which do not have the protective layer of enamel), the dentin becomes exposed. The tubules within the dentin allow heat, cold, acidic, or even sticky substances to reach the nerves inside the tooth, resulting in sharp, sudden pain, which we experience as tooth sensitivity.

This is why sensitive teeth are so painful – the nerve of the tooth, which is extremely sensitive to environmental changes, is being stimulated by triggers it would normally be shielded from. Every sip of hot coffee, every bite of ice cream, even a breath of cold air is enough to provoke a jolt of pain.

Preventing enamel erosion and gum recession can help prevent tooth sensitivity pain. If you already have sensitive teeth, there are treatments available to help reduce the pain. Always consult with a dental professional if you’re experiencing tooth sensitivity.

Is Tooth Sensitivity Serious?

While tooth sensitivity is quite common and often isn’t serious, it can lead to significant discomfort and impact your quality of life. It may cause you to avoid certain foods and drinks that trigger the sensitivity, potentially limiting your diet. Furthermore, the experience of sudden, sharp pain can be distressing, affecting your daily activities.

The seriousness of tooth sensitivity really depends on its underlying cause. For instance, if sensitivity is due to exposed dentin from aggressive toothbrushing, changing your brushing habits and using desensitizing toothpaste can significantly improve the condition. However, if your sensitivity is due to gum disease, cracked teeth, or decay, these are more serious conditions that require professional dental treatment.

Persistent or severe tooth sensitivity can sometimes indicate a more serious underlying dental problem, such as a cavity, a cracked or fractured tooth, a worn filling, or gum disease. If left untreated, these issues can worsen over time, leading to more severe dental problems, including tooth loss. Therefore, if you’re experiencing tooth sensitivity, it’s important to consult with a dental professional to identify the cause and determine the most effective treatment strategy. It’s always better to address the issue sooner rather than later to prevent further complications.

How to Stop Sensitive Teeth Pain?

There are various ways to manage tooth sensitivity:

1. Sensitive Teeth Home Remedies

Proper Oral Hygiene: Keeping your teeth and gums clean can help reduce sensitivity. This includes brushing your teeth at least twice a day and flossing regularly to remove plaque, the sticky film that forms on teeth. A clean mouth is less likely to develop tooth decay and gum disease, two significant causes of tooth sensitivity.

Use a Soft-Bristled Toothbrush: A toothbrush with hard bristles can contribute to gum recession and wear down the tooth enamel. Switching to a soft-bristled toothbrush can help prevent further damage to your teeth and gums. Be sure to replace your toothbrush every three to four months or when the bristles become frayed.

Avoid Acidic Foods and Drinks: Acidic substances can gradually wear away the tooth enamel, exposing the dentin and making your teeth more sensitive. Foods and drinks like citrus fruits, tomatoes, pickles, tea, and soda are high in acid. Try to limit your intake of these items and rinse your mouth with water after consuming them.

Use a Toothpaste for Sensitive Teeth: Special toothpaste designed for sensitive teeth contain compounds like potassium nitrate or strontium chloride, which help block the transmission of pain signals from the tooth surface to the nerve. It may take a few weeks for these toothpaste to take effect, so be patient and consistent with your usage.

Use a Fluoride Mouthwash: Using a fluoride mouthwash daily can strengthen tooth enamel and reduce sensitivity. It’s best to use it at a different time from brushing to allow the fluoride to adhere to your teeth.

Avoid Teeth Grinding: Teeth grinding, or bruxism, can wear down the enamel and lead to sensitivity. If you grind your teeth, especially while sleeping, consider getting a mouth guard from your dentist. This device can protect your teeth from the damaging effects of grinding.

Warm Salt Water Rinse: A warm salt water rinse can help soothe sensitive teeth. Dissolve half a teaspoon of salt in a cup of warm water, and then swish the solution around your mouth for about 30 seconds before spitting it out. Salt is a natural antiseptic that can reduce inflammation and improve oral health.

While these home remedies can provide relief from tooth sensitivity, they are not permanent solutions.

2. Sensitive Teeth Dental Treatments

If home remedies fail to alleviate tooth sensitivity or if the sensitivity is due to a more serious underlying issue, professional dental treatments may be necessary. Here are some dental procedures that can help alleviate tooth sensitivity:

Desensitizing Agents: If sensitivity persists despite using desensitizing toothpaste, your dentist can apply stronger desensitizing agents directly to the affected teeth. These agents work by blocking the tubules in the dentin, reducing the transmission of pain signals to the nerves.

Fluoride Gel or Varnish: Your dentist can apply fluoride gel or varnish to your sensitive teeth. This treatment strengthens tooth enamel, reduces the transmission of sensations, and helps protect the teeth against decay and sensitivity.

Dental Filling: If tooth decay has caused cavities in your teeth, leading to sensitivity, you may require a filling. This process involves removing the decayed tooth material, cleaning the affected area, and filling the cleaned-out cavity with a filling material. This prevents further decay and alleviates sensitivity.

Surgical Gum Graft: If your tooth sensitivity is due to gum recession, your dentist might recommend a gum graft. In this procedure, a small amount of gum tissue is taken from another part of your mouth and attached to the affected area. This protects the exposed root and reduces sensitivity.

Root Canal: If the other treatments are ineffective and your tooth sensitivity is severe or chronic, your dentist may recommend a root canal. This procedure treats problems in the tooth’s soft core or dental pulp, thereby alleviating pain and sensitivity. It is considered one of the most successful techniques for eliminating sensitivity.

Bonding: If the root surfaces of your teeth are exposed due to gum recession, your dentist may apply bonding resin to the sensitive root surfaces to reduce sensitivity.

Each of these treatments has its own benefits and potential drawbacks, and the best option for you will depend on the cause and severity of your tooth sensitivity. Your dentist can advise you on the most appropriate course of action to manage your sensitivity effectively.


In wrapping up, tooth sensitivity can be more than just a minor inconvenience; it can affect your ability to enjoy simple pleasures like cool ice cream or a warm cup of tea. However, remember that you’re not alone in this experience, and a wealth of solutions are available to help manage this condition.

Implementing at-home remedies, and combining them with professional dental treatments when necessary, can pave the way to overcoming tooth sensitivity. Moreover, prevention plays a key role here – maintaining proper oral hygiene can ward off the causes of sensitivity in the first place. 

So, let’s not allow tooth sensitivity to steal our joy of savoring our favorite food and drinks. With the right care, you can keep your teeth strong, your smile bright, and your life full of the flavors you love.
