Why Are My Teeth Sensitive?

Are you experiencing that sharp, uncomfortable sensation in your teeth when you indulge in your favorite ice cream or sip a hot cup of coffee? If so, you’re not alone. Tooth sensitivity is a common dental issue that affects people of all ages. But why are your teeth sensitive, and what can be done about it?

In this article, we’ll explore the various factors that contribute to tooth sensitivity and shed light on the solutions that can bring you relief. At Fit To Smile Dental, we understand the importance of addressing tooth sensitivity, and we’re here to guide you through the process of finding the right solutions for your unique needs.

So, if you’ve ever wondered, “Why are my teeth sensitive?” or “What can I do about it?” – you’re in the right place. Let’s dive into the world of tooth sensitivity and uncover the answers you’ve been searching for.

Common Causes of Tooth Sensitivity

To understand why your teeth may be sensitive, it’s essential to consider the various factors that contribute to this discomfort. Here are some common causes of tooth sensitivity:

Exposed Tooth Roots

Sometimes, the roots of your teeth become exposed due to gum recession or enamel erosion. Since the roots aren’t as well-protected as the crown (the visible part) of your tooth, they can be sensitive to temperature and pressure changes.

Enamel Wear

The enamel is the protective outer layer of your teeth. Over time, it can wear down due to aggressive brushing, acidic foods and drinks, or teeth grinding (bruxism). As enamel thins, it can expose the underlying dentin, leading to sensitivity.

Tooth Decay

Cavities, or dental caries, can create small openings in your tooth’s surface. These openings allow sensations like cold, heat, or sweets to reach the nerve inside your tooth, causing discomfort.

Cracked or Chipped Teeth

Trauma, biting down on hard objects, or even sudden temperature changes can lead to cracked or chipped teeth. These cracks can extend into the tooth’s inner layers, leading to sensitivity.

Dentin Hypersensitivity

Dentin is the layer beneath your enamel, and it contains tiny tubules that connect to your tooth’s nerve center. When dentin becomes exposed, it can transmit sensations more easily, resulting in sensitivity.

Acidic Foods and Drinks

Consuming highly acidic foods and beverages, such as citrus fruits, soda, or vinegar-based dressings, can erode tooth enamel over time, making teeth more sensitive.

Teeth Whitening Products

While teeth whitening can enhance your smile, it may cause temporary sensitivity. This occurs as the active ingredients penetrate the enamel to remove stains.

Oral Hygiene Practices

Brushing your teeth too vigorously or using a hard-bristle toothbrush can lead to enamel erosion and gum recession, increasing sensitivity.

Gum Disease

Advanced gum disease can lead to the loss of gum tissue and bone, exposing tooth roots and causing sensitivity.

Dental Procedures

Some dental treatments, such as root canal therapy or tooth extraction, may cause temporary sensitivity as your mouth heals.

Identifying the specific cause of your tooth sensitivity is crucial for finding the right treatment or preventive measures. At Fit To Smile Dental, our experienced team can help diagnose the root of your sensitivity and develop a personalized plan to address it effectively.

Understanding Enamel Erosion

Enamel erosion is a common factor contributing to tooth sensitivity. This protective outer layer of your teeth is essential for shielding the sensitive dentin underneath. When enamel erodes, your teeth become more vulnerable to various stimuli, leading to sensitivity.

There are several factors that can lead to enamel erosion:

Acidic Foods and Drinks

Consuming acidic items like citrus fruits, carbonated sodas, and fruit juices can expose your teeth to acid attacks. Acid softens and wears away the enamel, gradually eroding its protective qualities.

Acid Reflux

Gastroesophageal reflux disease (GERD) or frequent heartburn can introduce stomach acids into your mouth, leading to enamel erosion over time.

Dry Mouth

Saliva plays a crucial role in maintaining oral health. It helps neutralize acids and remineralize enamel. Conditions that reduce saliva production, such as medication side effects or certain medical conditions, can contribute to enamel erosion.

Abrasive Toothpaste or Brushing

Brushing your teeth with abrasive toothpaste or using a hard-bristle toothbrush can physically wear down the enamel, especially if done vigorously.

Teeth Grinding (Bruxism)

Grinding or clenching your teeth, especially during sleep, can exert significant pressure on the enamel, leading to its gradual erosion.

Chewing Ice or Hard Objects

Biting down on hard objects like ice, pens, or bottle caps can chip or crack your teeth, which can expose the underlying dentin and lead to sensitivity.

Medical Conditions

Some medical conditions, such as acid reflux, eating disorders, or certain autoimmune diseases, can contribute to enamel erosion.

Frequent Snacking

Constantly snacking or sipping on acidic or sugary beverages throughout the day can create an environment where enamel is under constant attack.

Understanding the causes of enamel erosion is essential for addressing tooth sensitivity effectively. If you suspect that enamel erosion is the reason for your sensitive teeth, consulting with our team at Fit To Smile Dental can help identify the underlying issues and develop a personalized plan to protect and strengthen your enamel.

Gum Recession and Tooth Sensitivity

In addition to enamel erosion, gum recession is another leading cause of tooth sensitivity. Your gums play a vital role in protecting the roots of your teeth and the sensitive dentin beneath. When your gums recede or pull away from the tooth surface, it can expose the dentin, leading to heightened sensitivity.

Several factors can contribute to gum recession:

Aggressive Brushing

Brushing your teeth too vigorously or using a hard-bristle toothbrush can lead to gum recession. It’s important to brush gently with a soft-bristle toothbrush to avoid damaging your gums.

Gingivitis and Gum Disease

Untreated gum disease can cause your gums to recede over time. This is why it’s crucial to maintain regular dental check-ups and address gum issues promptly.


As we age, our gums naturally tend to recede. This is a normal part of the aging process, but it can contribute to tooth sensitivity.

Tobacco Use

Smoking or using other tobacco products can increase the risk of gum disease, which can, in turn, lead to gum recession.


Oral piercings, such as tongue or lip piercings, can contribute to gum recession if the jewelry comes into contact with the gums.

Orthodontic Treatment

In some cases, orthodontic treatment can lead to temporary gum recession. However, this is typically a manageable side effect.

If you’re experiencing gum recession and tooth sensitivity, it’s essential to address the underlying causes. Our team at Fit To Smile Dental can assess your gum health, recommend appropriate treatments, and provide guidance on maintaining healthy gums to reduce sensitivity and protect your oral health.

Tooth Decay and Sensitivity

Tooth decay, commonly known as cavities or dental caries, can also be a significant factor contributing to tooth sensitivity. This condition occurs when the enamel of your tooth is eroded by acid-producing bacteria, leading to the formation of small holes or cavities in the tooth’s structure.

Here’s how tooth decay can lead to sensitivity:

Enamel Damage

As tooth decay progresses, it can result in the weakening and thinning of the enamel, the outer protective layer of your teeth. When the enamel is compromised, it leaves the underlying dentin exposed.

Dentin Sensitivity

Dentin, the layer beneath the enamel, contains microscopic tubules that connect to the nerve center of the tooth. When the dentin is exposed, it becomes more sensitive to external stimuli, such as hot, cold, sweet, or acidic foods and beverages.

Sensitivity to Sweet and Sour

People with tooth decay often experience increased sensitivity, especially when consuming sugary or acidic foods. The damaged enamel and exposed dentin make it easier for these substances to reach the nerve, causing discomfort.

Painful Sensations

Tooth decay-related sensitivity can manifest as sharp, shooting pain when you consume something hot or cold. It can also lead to a persistent ache or discomfort in the affected tooth.

Addressing tooth decay is crucial not only for alleviating sensitivity but also for preventing the progression of the decay and potential complications. Our team at Fit To Smile Dental can provide comprehensive dental examinations, identify areas of concern, and recommend appropriate treatments to restore your oral health and reduce tooth sensitivity caused by tooth decay.

Other Causes of Sensitivity

While enamel erosion, gum recession, and tooth decay are common causes of tooth sensitivity, several other factors can contribute to this issue. Understanding these additional causes is essential for comprehensive dental care:

Tooth Grinding (Bruxism)

Grinding or clenching your teeth, often involuntarily during sleep, can wear down enamel over time. This can lead to tooth sensitivity and even cracked or chipped teeth. A custom-made nightguard can help protect your teeth if you grind them while sleeping.

Tooth Whitening

Over-the-counter or professional teeth whitening treatments can cause temporary sensitivity. This occurs because the whitening agents can penetrate the enamel and irritate the nerves. Sensitivity typically subsides after treatment but can be managed with desensitizing toothpaste.

Cracked Teeth

Cracks or fractures in your teeth can expose the sensitive dentin layer, leading to pain and sensitivity when chewing or consuming hot and cold foods. Depending on the severity of the crack, treatment may involve bonding, a crown, or in severe cases, extraction.

Acidic Foods and Drinks

Frequent consumption of acidic foods and beverages like citrus fruits, sodas, and certain sports drinks can erode enamel and lead to tooth sensitivity. Reducing your intake of these acidic items and practicing good oral hygiene can help prevent sensitivity.

Age-Related Recession

As you age, your gums may naturally recede, exposing the tooth roots. This can lead to sensitivity, especially in older adults. Proper oral hygiene and regular dental check-ups are crucial for maintaining gum health.


Some medications, including antihypertensives, antidepressants, and antihistamines, can cause dry mouth. Reduced saliva production can increase the risk of tooth decay and sensitivity. If you experience dry mouth as a side effect of medication, speak with your dentist for strategies to mitigate its impact on your oral health.

Recent Dental Procedures

Tooth sensitivity can be a temporary side effect of certain dental procedures, such as fillings, crowns, or root canals. This sensitivity usually subsides within a few days or weeks.

If you’re experiencing tooth sensitivity, it’s essential to identify the underlying cause and seek appropriate dental care. At Fit To Smile Dental, we specialize in diagnosing and treating tooth sensitivity, tailoring our approach to your specific needs. Whether you’re dealing with enamel erosion, gum recession, or other causes, our team is here to help alleviate your discomfort and improve your oral health.

Preventing Tooth Sensitivity

Preventing tooth sensitivity involves maintaining good oral hygiene practices and making lifestyle choices that protect your teeth and gums. Here are some strategies to help keep your teeth comfortable and sensitivity-free:

Regular Dental Check-Ups

Schedule routine dental check-ups with Fit To Smile Dental. These appointments allow your dentist to identify and address potential issues before they lead to sensitivity. Professional cleanings can also help remove plaque and tartar buildup, reducing the risk of tooth decay.

Brushing Technique

Use a soft-bristled toothbrush and gentle brushing techniques. Aggressive brushing can wear down enamel and contribute to gum recession. Brush for at least two minutes, reaching all surfaces of your teeth and gums.

Desensitizing Toothpaste

Consider using a desensitizing toothpaste. These toothpaste varieties contain compounds that help block pain signals from reaching the nerves in your teeth. Your dentist can recommend an appropriate brand for your needs.

Fluoride Toothpaste

Choose toothpaste with fluoride, as it strengthens enamel and helps prevent tooth decay. Fluoride can also reduce sensitivity by repairing minor enamel damage.

Avoid Acidic Foods and Beverages

Limit your consumption of acidic foods and drinks, such as citrus fruits, vinegar-based dressings, soda, and energy drinks. If you do consume acidic items, rinse your mouth with water afterward to neutralize acids.

Wear a Mouthguard

If you grind or clench your teeth, especially at night, wear a custom-made mouthguard. This will protect your teeth from enamel wear and potential cracks.

Balanced Diet

Maintain a balanced diet rich in calcium and vitamin D, which are essential for strong teeth and bones. Dairy products, leafy greens, and fortified foods are good sources.

Stay Hydrated

Drink plenty of water throughout the day. Water helps maintain saliva production, which is crucial for protecting teeth from sensitivity and decay.

Quit Smoking

Smoking can contribute to gum disease and enamel erosion. If you smoke, consider quitting for the benefit of your oral and overall health.

Stress Management

Manage stress through relaxation techniques like yoga, meditation, or deep breathing exercises. Stress can contribute to teeth grinding, which can lead to sensitivity.

By adopting these preventive measures and maintaining a healthy oral care routine, you can reduce the risk of tooth sensitivity and enjoy a comfortable, pain-free smile. Fit To Smile Dental is here to support you in your journey towards optimal oral health and well-being.
