Sensitive Teeth Causes: What are the Reasons for Sensitive Teeth?

​How does it feel to be God's beloved kid for people who simply bite into their preferred ice cream without feeling any discomfort in their teeth? 

For the rest of us, dental sensitivity is a daily struggle that affects even the most simple pleasures.

Daily tasks like drinking tea or a cold beverage, or even brushing your teeth vigorously, can throw you into a world of discomfort. 

We understand your agony, which is why we're here to assist you in understanding what's causing it and how to alleviate the tingling sensation and pain. 

But, before we get into what causes tooth sensitivity, let us first define it.​

Understanding Tooth Sensitivity

​Sensitivity in teeth is a frequent condition in which nerves are easily stimulated by specific external stimuli. 

This causes dental pain or discomfort in one or more teeth. Sensitive teeth symptoms typically include a sharp, shooting pain. It makes drinking or eating certain foods uncomfortable. 

Sensitive teeth can be remedied by seeing a dentist and taking certain precautions on your own. Hot and cold, sweet or spicy meals can all cause dental sensitivity.​

Dental Enamel Erosion: The Primary Culprit

Dental enamel degradation is one of the most common reasons for tooth sensitivity. 

Enamel erosion occurs when the hard outer layer of tooth enamel wears away gradually as a result of causes such as acidic foods and beverages, forceful brushing, and acid reflux. 

The underlying dentin is exposed as the enamel thins, causing sensitivity. To reduce enamel erosion, use gentle brushing techniques, avoid abrasive toothpaste, and limit your intake of acidic meals and liquids. 

Regular dental check-ups can also aid in the detection of early indicators of enamel erosion and the provision of prompt therapies.

Tooth Decay and Cavities: A Common Cause of Sensitivity

Tooth sensitivity may be caused by tooth decay and cavities. Cavities can develop when oral bacteria in the mouth overgrow and produce acids that attack the tooth enamel.

These cavities expose the sensitive inner layers of the tooth, causing discomfort and sensitivity. Tooth decay can be avoided by good oral hygiene practices such as regular brushing, flossing, and dental examinations. 

Additionally, reducing sugary and acidic food and drink consumption can aid in cavity prevention and reduce tooth sensitivity is also recommended.

Gum Recession: Exposing the Dentin

Gum recession occurs when the gum tissue surrounding your teeth begins to pull back, exposing the tooth roots and dentin. This condition can be caused by factors like gum disease, aggressive brushing, or genetics. Once the dentin is exposed, it becomes sensitive to external stimuli, resulting in tooth sensitivity.

To prevent gum recession, practising good oral hygiene is essential. Adopting gentle brushing techniques, such as using a soft-bristled toothbrush and avoiding excessive pressure, will help protect your gums.

Common Causes of Gum Recession and Tooth Sensitivity:

1. Brushing Too Vigorously
   Brushing with too much force, especially with a hard-bristled toothbrush, can wear down tooth enamel and push the gums back. This exposes the tooth base, leading to sensitivity.

2. Acidic or High-Sugar Diet
   Foods and drinks high in acid or sugar—such as soda, coffee, tomato sauce, candies, refined carbs, and citrus fruits—can erode enamel, exposing the dentin and increasing sensitivity.

3. Using Acidic Mouthwash
   Just like acidic foods, long-term use of acidic mouthwashes (especially those containing alcohol or harsh chemicals) can wear away enamel and worsen sensitivity.

4. Teeth Grinding
   Grinding or clenching your teeth, whether during the day or while sleeping, gradually wears down enamel, leaving the dentin exposed. This habit can lead to ongoing tooth sensitivity.

5. Gum Disease
   Inflamed gums can recede or peel away from the teeth due to gum disease, exposing sensitive areas and causing discomfort.

6. Temporary Sensitivity
   Some dental treatments, like teeth whitening, can cause temporary sensitivity. Fortunately, this usually subsides shortly after the procedure.

Brushing Habits: The Impact on Tooth Sensitivity

While proper oral hygiene is crucial, aggressive brushing techniques can contribute to tooth sensitivity. 

Brushing too hard or using a toothbrush with stiff bristles can wear down the tooth enamel, leading to dentin exposure and sensitivity.

It is recommended to use a soft-bristled toothbrush and brush gently in a circular motion. 

Using toothpaste specifically formulated for sensitive teeth can help alleviate sensitivity and protect the enamel.

Acidic Foods and Beverages: The Enemy of Enamel

Consumption of highly acidic foods and beverages can erode the tooth enamel over time, contributing to tooth sensitivity. 

Acidic foods and drinks include citrus fruits, carbonated drinks, wine, and certain types of vinegar. 

These substances weaken the enamel, making the teeth more susceptible to sensitivity. To minimize the impact of acidic foods and beverages, it is advisable to rinse the mouth with water after consumption. 

Waiting for at least 30 minutes before brushing the teeth can also prevent further enamel erosion, as brushing immediately after consuming acidic substances can further weaken the enamel.

Teeth Grinding (Bruxism): Wearing Down the Enamel

Bruxism, also referred to as teeth grinding or clenching, is characterized by the habitual and frequent grinding or clenching of teeth, often unconsciously. 

The continual friction and pressure can wear down the tooth enamel, exposing the dentin.

It's important to consult a dentist If bruxism is suspected. To address bruxism and lessen its negative effects on tooth sensitivity, they can provide a customized treatment plan. 

This may involve using a mouth guard or splint to protect the teeth during sleep or stress management techniques to reduce teeth grinding.

Dental Procedures: Temporary Sensitivity

Temporary tooth discomfort or pain can result from some dental procedures, such as teeth whitening, dental fillings, or professional cleanings. 

The manipulation of the tooth structures during the procedure or the exposure of the underlying dentin frequently causes this sensation.

Before getting any dental work done, it's important to communicate with your dentist about any existing tooth sensitivity. 

Dentists can accordingly take precautions to minimize discomfort and offer post-treatment recommendations.

Cracked Teeth: Nerves Under Attack

Another factor contributing to tooth sensitivity is cracked teeth. When a tooth is cracked or fractured, it exposes the nerves within the tooth. 

Due to this sensitivity to temperature changes or biting
"g pressure increases. Cracked teeth might occur due to various reasons, such as teeth grinding, biting on hard objects, or trauma.

If you suspect a cracked tooth, it is essential to seek dental attention promptly. Depending on the severity of the crack, treatment options may include dental bonding, a dental crown, or in severe cases, root canal therapy.

Excessive Plaque and Tartar Buildup: Affecting Tooth Sensitivity

Tooth sensitivity may be exacerbated by plaque and tartar buildup on the teeth. If not removed, plaque, which is a sticky film of germs that accumulates on the teeth, can harden into tartar. 

Plaque and tartar accumulation near the gumline can lead to gum disease and gum recession, thereby increasing the risk of tooth sensitivity.

Maintaining a consistent oral hygiene practice, such as brushing twice a day, flossing daily, and scheduling routine dental cleanings, is essential to preventing plaque and tartar buildup. 

Removing plaque and tartar, these steps might lessen the chance of dental discomfort.

What to do if you have Tooth Sensitivity?

1. Use Desensitizing Toothpaste
   Switch to toothpaste specifically designed for sensitive teeth. It helps reduce sensitivity by protecting exposed dentin. For extra relief, apply a small amount to sensitive areas before bed using a cotton swab or your fingertip.
2. Visit Your Dentist
   If sensitivity becomes severe, consult your dentist. They can assess your condition and recommend the most effective treatment for lasting relief.
3. Maintain Good Oral Hygiene
   Continue brushing twice daily with a soft-bristled toothbrush and floss regularly to prevent plaque buildup. Avoid acidic foods and drinks that can worsen sensitivity.
