TOOTH SENSITIVITY: WHAT IT IS AND ITS CAUSES, EXPLAINED

tooth sensitivity

INTRODUCTION

Tooth sensitivity, or dentin hypersensitivity, occurs when the protective layers of the teeth, namely enamel and cementum, are compromised, exposing the underlying dentin. Dentin is a porous tissue that contains microscopic tubules leading to the tooth’s nerve center. When these tubules are exposed, external triggers can easily reach the nerves, causing a painful sensation.

COMMON CAUSES OF TOOTH SENSITIVITY

1. Enamel Erosion: The enamel, which is the hard outer layer of the tooth, can wear down over time due to various factors. Consumption of acidic foods and beverages, such as citrus fruits, soda, and wine, can erode enamel, leaving dentin exposed.

2. Gum Recession: Gum recession, often a result of periodontal disease or aggressive tooth brushing, exposes the tooth roots. Unlike the crown of the tooth, roots are covered by cementum, which is much thinner than enamel and more susceptible to wear and tear, leading to sensitivity.

3. Tooth Decay: Cavities and dental caries create holes in the enamel, allowing stimuli to reach the dentin. Decay near the gum line can also expose the tooth roots, increasing sensitivity.

4. Dental Procedures: Certain dental treatments, such as teeth whitening, cleanings, or fillings, can cause temporary sensitivity. Whitening agents, in particular, can penetrate the enamel and irritate the dentin.

5. Teeth Grinding (Bruxism): Chronic grinding or clenching of teeth can wear down enamel, exposing the dentin. It can also lead to micro-cracks in the tooth, which can increase sensitivity.

6. Cracked or Chipped Teeth: Physical damage to teeth, such as cracks or chips, can expose the dentin and cause sensitivity. This damage can result from accidents, chewing on hard objects, or grinding.

7. Aggressive Brushing: Using a hard-bristled toothbrush or brushing with excessive force can erode enamel and irritate gums, leading to exposure of the sensitive dentin.

MANAGING AND PREVENTING TOOTH SENSITIVITY

Addressing tooth sensitivity requires a combination of good oral hygiene practices, dietary changes, and professional dental care. Here are some effective strategies:

1. Use Desensitizing Toothpaste: These toothpastes contain compounds that help block the transmission of sensation from the tooth surface to the nerve. Regular use can significantly reduce sensitivity over time.

2. Adopt Gentle Brushing Techniques: Use a soft-bristled toothbrush and brush gently in circular motions. Avoid aggressive brushing and ensure you cover all areas of your mouth effectively without causing damage.

3. Watch Your Diet: Limit the intake of acidic foods and drinks. Rinse your mouth with water after consuming acidic substances and wait at least 30 minutes before brushing to prevent enamel erosion.

4. Wear a Mouthguard: If you grind your teeth at night, wearing a custom-fitted mouthguard can protect your teeth from further damage.

5. Seek Professional Treatments: Your dentist can apply fluoride treatments or dental sealants to strengthen enamel and reduce sensitivity. In severe cases, procedures like bonding, gum grafting, or root canal therapy may be necessary.

6. Maintain Regular Dental Check-ups: Routine visits to the dentist can help identify and address dental issues before they lead to severe sensitivity. Your dentist can provide personalized advice and treatment options based on your specific needs.

CONCLUSION

Tooth sensitivity can be a bothersome condition, but understanding its causes and implementing effective prevention and management strategies can help alleviate the discomfort. By adopting good oral hygiene practices, making mindful dietary choices, and seeking professional dental care, you can protect your teeth from sensitivity and enjoy a pain-free smile. If you experience persistent or severe tooth sensitivity, consult your dentist to determine the underlying cause and receive appropriate treatment.
