Tooth sensitivity in kids is common and often signals an underlying issue. Sensitivity may appear as pain with cold drinks, brushing, or sweet foods.
Common Causes of Pediatric Tooth Sensitivity
• Early enamel erosion
• Exposed dentin
• Tooth decay
• Gum recession (rare but possible)
• New teeth erupting
• Cracked enamel from grinding
• Post-dental treatment sensitivity
Identifying the cause determines the correct treatment.
Evidence-Based Treatments
1. Fluoride Therapy
Strengthens enamel and decreases nerve response. Applied professionally or through prescription toothpaste.
2. Desensitizing Toothpaste
Ingredients like potassium nitrate or stannous fluoride block pain signals from reaching the tooth nerve.
3. Sealants
For worn or porous enamel, sealants protect exposed surfaces and reduce sensitivity.
4. Treatment for Tooth Decay
If cavities are the cause, prompt treatment is critical. Delays lead to deeper sensitivity and infection.
5. Mouthguards for Grinding
Nighttime grinding stresses enamel. A custom pediatric mouthguard prevents further damage.
6. ICON Resin or Bonding
For enamel defects (MIH, fluorosis), resin infiltration restores structure and decreases pain.
7. Eliminating Acidic Foods
Reducing citrus, sodas, vinegar-based snacks, and sports drinks helps protect weakened enamel.
When Sensitivity Is an Emergency
Seek same-day care if sensitivity is:
• Sudden and severe
• Triggered by biting down
• Accompanied by swelling
• Localized to one tooth
These signs may indicate infection or trauma.
