Do you feel a sharp, sudden pain in your teeth when you eat something cold, hot, sweet, or even take a breath of cool air? This is tooth sensitivity.
The soft nerve inside your tooth is protected by hard enamel. When this protective layer thins due to receding gums, improper brushing wear, or erosion from acidic foods, it exposes the dentin underneath. Dentin contains tiny tubes that lead directly to the nerve. Stimuli like temperature and sweetness can travel straight through these "micro-tubes," causing that short, sharp pain.
Key culprits include:
1. Vigorous side-to-side brushing causing notches near the gumline.
2. Gum recession exposing the sensitive tooth root.
3. Frequently consuming acidic foods and drinks that erode enamel.
4. Teeth grinding or existing cavities.
How to manage sensitivity?
1. Switch to a desensitizing toothpaste: Use it daily. It helps block the dentin tubules, stopping the stimulus from reaching the nerve.
2. Learn gentle brushing: Use a soft-bristled toothbrush and brush gently in a circular or up-and-down motion to avoid wearing away gums and enamel.
3. Limit acidic foods/drinks: Reduce intake of sodas and juices. Don't brush immediately after consuming them.
4. See your dentist: Identify the root cause and get professional treatment (like fluoride varnish or fillings).
Don't let sensitivity ruin your enjoyment of food and life. Start treating your teeth gently today!
