Sensitive Teeth: 9 Causes and Gentle Solutions That Work

Tooth sensitivity affects 1 in 8 adults, causing sharp pain from hot, cold, sweet, or acidic foods. Understanding the causes and gentle solutions can restore your comfort and confidence.

What Causes Tooth Sensitivity?

1. Enamel Erosion

Acidic foods, drinks, and aggressive brushing wear away protective enamel, exposing sensitive dentin underneath.

2. Gum Recession

Receding gums expose tooth roots, which lack enamel protection and connect directly to nerve pathways.

3. Worn Fillings

Old or damaged fillings can expose sensitive areas of teeth to temperature and pressure changes.

4. Teeth Grinding

Bruxism wears down enamel and can crack teeth, creating pathways for sensitivity triggers.

5. Aggressive Brushing

Hard bristles and excessive pressure damage enamel and irritate gums, leading to sensitivity over time.

6. Whitening Overuse

Excessive whitening treatments can temporarily increase sensitivity by opening enamel pores.

7. Cracked Teeth

Even tiny cracks can expose inner tooth layers to temperature changes and bacteria.

8. Recent Dental Work

Temporary sensitivity after fillings, crowns, or cleanings usually resolves within days.

9. Acidic Diet

Regular consumption of citrus, soda, or wine gradually weakens enamel protection.

9 Gentle Solutions for Sensitive Teeth

1. Switch to Sonic Brushing

The LUNA's gentle 39,000 vibrations provide thorough cleaning without the aggressive scrubbing that worsens sensitivity. Sonic technology is ideal for sensitive teeth.

2. Use Desensitizing Toothpaste

Potassium nitrate or stannous fluoride toothpastes block pain signals. Use consistently for 2-4 weeks to see results.

3. Gentle Brushing Technique

Let sonic technology do the work - apply minimal pressure and use soft, circular motions. Never scrub back and forth aggressively.

4. Replace Brush Heads Regularly

Fresh Bumper Heads maintain optimal gentleness. Worn bristles become harsh and can worsen sensitivity.

5. Fluoride Rinse

Use fluoride mouthwash daily to strengthen enamel and reduce sensitivity over time.

6. Avoid Acidic Triggers

Limit citrus fruits, soda, and wine. When you do consume them, rinse with water and wait 30 minutes before brushing.

7. Night Guard for Grinding

If you grind your teeth, a custom night guard protects enamel and reduces sensitivity.

8. Saltwater Rinse

Mix 1/2 teaspoon salt in warm water and rinse twice daily to reduce inflammation and sensitivity.

9. Professional Fluoride Treatment

Your dentist can apply concentrated fluoride to strengthen enamel and reduce sensitivity quickly.

Foods That Help Sensitive Teeth
