Teeth Sensitivity

Teeth sensitivity typically arises when the inner layer of your teeth, known as dentin, becomes exposed. This exposure can occur due to factors like erosion and gum recession, where the gum tissue recedes from the teeth, revealing the underlying roots.

The roots of your teeth, which lack the protective enamel, contain numerous small channels called dentinal tubules that lead to the innermost part of the tooth, the pulp. These dentinal tubules serve as pathways for various stimuli, such as hot, cold, or sweet foods, to reach the nerve within the tooth, causing the discomfort associated with tooth sensitivity.

It's important to note that dental sensitivity can also be indicative of other dental issues, including cavities, gum disease, or tooth fractures.

Possible Causes: What prompts sudden tooth sensitivity?

Multiple factors can contribute to the development of tooth sensitivity, including:

  1. Vigorous brushing: Over time, excessive brushing or the use of a hard-bristle toothbrush can wear down enamel and expose the dentin. It can also lead to gum recession.
  2. Gum recession: Some individuals may have genetically thin gum tissue, while others may experience gum recession due to periodontal disease. Gum recession results in the exposure of tooth roots.
  3. Gum disease: Inflammation and tenderness in the gum tissue can lead to sensitivity by causing the loss of supportive ligaments, exposing the root surface that leads directly to the tooth nerve.
  4. Cracked teeth: Chipped or broken teeth can harbor bacteria from plaque, which can infiltrate the pulp, causing inflammation.
  5. Teeth grinding: Grinding or clenching teeth can wear down the enamel, exposing the underlying dentin.
  6. Teeth whitening products: These products can be a significant contributor to teeth sensitivity. Consult a dentist for teeth whitening options suitable for sensitive teeth.
  7. Age: Tooth sensitivity is often most prevalent between the ages of 25 and 30.
  8. Plaque buildup: The presence of plaque on the root surfaces can trigger sensitivity.
  9. Mouthwash use: Certain over-the-counter mouthwashes contain acids that can exacerbate teeth sensitivity when dentin is exposed. These acids further damage the dentin layer. Consult your dentist about using a neutral fluoride solution if you have dentin sensitivity.
  10. Acidic foods: Regular consumption of highly acidic foods, like citrus fruits, tomatoes, pickles, and tea, can contribute to enamel erosion.
  11. Recent dental procedures: Some people may experience teeth sensitivity following dental work such as fillings, cleanings, or restorations. This sensitivity is typically temporary and subsides within four to six weeks.

Is sensitive tooth pain indicative of infection?

Not always. Tooth sensitivity may stem from tooth erosion, gum recession, or, in some cases, a cracked or infected tooth. Infection-related tooth pain can manifest as a dull, persistent ache or sharp, throbbing discomfort.

If you have severe and persistent tooth sensitivity, it's advisable to promptly contact a dentist for further guidance.

Care and Treatment: Can tooth sensitivity resolve on its own?

Yes, tooth sensitivity may spontaneously subside in certain cases, especially when linked to recent dental procedures like fillings or root canals. However, if your sensitivity persists and doesn't alleviate, consulting a dentist is recommended. This may be an indication of worn enamel or exposed tooth roots, which could necessitate treatment.

How can you alleviate tooth sensitivity?

The appropriate treatment depends on the underlying cause of your sensitivity. If you experience persistent sensitivity or discomfort, it's vital to schedule an appointment with your dentist. They will assess your condition to rule out any serious issues and recommend suitable treatments.

To diminish the risk of sensitivity due to normal wear and tear:

  • Use desensitizing toothpaste: Various brands offer toothpaste for sensitive teeth. Regular use can reduce sensitivity. You may need to try several brands to find the most effective one. It's also recommended to apply a thin layer of toothpaste to exposed tooth roots before bedtime.
  • Maintain proper oral hygiene: Continue to follow correct brushing and flossing techniques for thorough dental care.
  • Utilize a soft-bristled toothbrush: This minimizes toothbrush-related abrasion on the tooth surface and reduces gum irritation.
  • Monitor your dietary choices: Regular consumption of highly acidic foods can gradually erode tooth enamel and expose dentin, intensifying sensitivity and causing discomfort.
  • Use fluoride dental products: Daily use of fluoride mouth rinse can help reduce sensitivity. Consult your dentist for suitable at-home products.
  • Prevent teeth grinding: If you grind or clench your teeth, consider using a mouth guard during the night.
  • Regular dental check-ups: Attend routine professional exams, cleanings, and fluoride treatments.

If you continue to experience discomfort, consult your dentist. Some dental procedures may help alleviate sensitivity, including:

  • Dental bonding to cover exposed root surfaces.
  • Application of fluoride varnishes to exposed root surfaces.
  • Use of dentin sealers on exposed root surfaces.

When should you contact your dentist for tooth sensitivity?

It's advisable to arrange a dental appointment if you experience tooth sensitivity to cold, heat, or sweets.

Questions to ask your dentist may include:

  • What is the cause of my tooth sensitivity?
  • Do I require treatment for my sensitive teeth?
  • Are there preventive measures to avoid tooth sensitivity in the future?
  • Which over-the-counter products do you recommend?
  • How often should I schedule teeth cleanings?

Tooth sensitivity can result from various factors, and its treatment depends on the underlying cause. Consulting with a dentist is essential to diagnose the issue and determine the appropriate treatment to address it.
