Sensitive Teeth

What Are Sensitive Teeth?

Tooth sensitivity, or dentin hypersensitivity, refers to pain or discomfort that occurs when the teeth are exposed to certain stimuli, such as hot, cold, sweet, or acidic foods and drinks. The discomfort can range from mild to sharp and intense, depending on the cause of sensitivity.

Teeth sensitivity occurs when the dentin (the inner part of your tooth beneath the enamel) becomes exposed. Dentin is a porous material that contains tiny tubules filled with fluid. When these tubules are exposed to external stimuli, the fluid inside moves, triggering pain signals to the nerves inside the tooth.

Common Causes of Tooth Sensitivity

Several factors can lead to or contribute to tooth sensitivity. Identifying the root cause is essential for finding the most effective treatment. Common causes include:

1. Worn Enamel

Enamel is the hard outer layer of your teeth that protects the sensitive dentin underneath. Over time, enamel can wear away due to excessive brushing, using a hard-bristled toothbrush, grinding your teeth, or consuming acidic foods and drinks. As enamel thins, the underlying dentin becomes exposed, leading to increased sensitivity.

2. Gum Recession

Your gums protect the roots of your teeth. However, when the gums recede due to gum disease or aging, the tooth roots become exposed. Tooth roots are more sensitive than enamel, and when they’re exposed, you may experience discomfort or pain when eating hot, cold, or acidic foods.

3. Tooth Decay or Cavities

Cavities can cause areas of your teeth to become weakened and exposed to sensitivity. When decay reaches the dentin layer, it can lead to discomfort, especially when eating or drinking.

4. Cracked or Chipped Teeth

A cracked or chipped tooth can expose the dentin, which may result in pain when the tooth is exposed to temperature changes or certain foods. Cracks can also trap food particles, leading to further irritation of the dentin.

5. Teeth Grinding (Bruxism)

If you grind or clench your teeth, especially while sleeping, it can wear down the enamel and lead to tooth sensitivity. This habit can also contribute to gum recession, further exacerbating the problem.

6. Recent Dental Work

Sometimes, dental procedures such as fillings, crowns, or teeth whitening treatments can temporarily make your teeth more sensitive. This sensitivity usually improves as your teeth heal and adjust after the procedure.

7. Acidic Foods and Beverages

Foods and drinks like citrus, soda, and wine contain acids that can erode tooth enamel over time. If you regularly consume these items, they can contribute to tooth sensitivity.

8. Gum Disease

Gum disease, particularly in its advanced stages (periodontitis), can cause the gums to pull away from the teeth, exposing the tooth roots and leading to sensitivity.

How We Diagnose Tooth Sensitivity

If you’re experiencing tooth sensitivity, it’s essential to have it evaluated by a dentist. Our process includes:

1. Detailed Patient History
   We’ll ask about your dental history, habits, and any recent dental work you’ve had. This helps us determine potential contributing factors.
2. Clinical Examination
   Our dentist will carefully examine your teeth, gums, and jaw to check for signs of enamel wear, gum recession, cavities, cracks, or other dental issues that could be contributing to your sensitivity.
3. X-rays
   In some cases, we may take X-rays to evaluate the extent of enamel erosion, check for cavities or fractures, and identify other potential causes of your sensitivity that aren’t visible during a routine examination.
4. Sensitivity Tests
   We may perform a sensitivity test to assess how your teeth react to different stimuli, such as cold air or a cold drink. This helps pinpoint which areas of your mouth are the most sensitive and allows us to tailor treatment accordingly.

Treatment Options for Sensitive Teeth

Once we’ve diagnosed the cause of your tooth sensitivity, we can recommend a treatment plan to help relieve your discomfort and protect your teeth from further damage. Depending on the severity of your sensitivity and the underlying cause, treatment options may include:

1. Desensitizing Toothpaste

For mild sensitivity, we often recommend using desensitizing toothpaste, which contains compounds that block the pathways to the nerves in your teeth. These products can help reduce sensitivity over time and provide ongoing relief with regular use.

2. Fluoride Treatments

If enamel erosion is a concern, we may apply fluoride treatments to your teeth. Fluoride strengthens enamel, making it more resistant to acid erosion and reducing sensitivity. These treatments can be applied in-office or recommended for home use in the form of gels or rinses.

3. Dental Sealants

For exposed dentin, we may apply dental sealants, a protective coating that shields the sensitive areas of your teeth. Sealants help prevent further exposure to irritants and can reduce sensitivity.

4. Gum Grafting

If your sensitivity is caused by gum recession, we may recommend a gum graft. This procedure involves taking tissue from another part of your mouth (or using donor tissue) to cover the exposed tooth roots. Gum grafting not only helps alleviate sensitivity but also protects your teeth from further gum recession.

5. Bonding or Fillings

For cracked or chipped teeth, bonding or fillings can be used to seal the exposed dentin. Dental bonding involves applying a tooth-colored resin to the affected area to restore the tooth’s surface and reduce sensitivity.

6. Night Guards for Teeth Grinding

If teeth grinding is contributing to your sensitivity, we may recommend a night guard to wear while you sleep. Night guards help protect your teeth from the damaging effects of grinding and clenching, reducing wear on the enamel and preventing further sensitivity.

7. Root Canal Treatment

In severe cases where sensitivity is caused by deep decay or infection that has reached the tooth’s nerve, a root canal may be necessary. This treatment involves removing the infected tissue inside the tooth and sealing it to prevent further damage. While this treatment is typically reserved for more severe cases, it can provide long-term relief for chronic sensitivity.

8. Dietary and Lifestyle Modifications

We may recommend making some changes to your diet and lifestyle to help manage your sensitivity. This can include reducing the consumption of acidic foods and drinks, avoiding overly hot or cold foods, and using a soft-bristled toothbrush to prevent further enamel erosion.

How to Prevent Tooth Sensitivity

Preventing tooth sensitivity involves maintaining good oral hygiene and protecting your teeth from damage. Some simple habits to incorporate into your routine include:

• Brush Gently: Use a soft-bristled toothbrush and brush your teeth gently to avoid wearing down your enamel.
• Floss Daily: Regular flossing helps remove plaque and food particles from between your teeth and along the gumline, preventing gum disease and enamel erosion.
• Use Fluoride Toothpaste: Fluoride toothpaste helps strengthen enamel and prevent cavities, which can lead to sensitivity.
• Avoid Acidic Foods and Drinks: Reduce your intake of acidic foods and drinks like citrus, soda, and wine, which can erode enamel.
• Wear a Night Guard: If you grind your teeth at night, wearing a night guard can help protect your teeth from further wear and reduce sensitivity.
• Regular Dental Checkups: Regular visits for professional cleanings and exams help detect potential issues early and prevent tooth sensitivity from becoming a long-term problem.
