Common Causes of Tooth Sensitivity

• Worn tooth enamel from acidic foods, acid reflux, or aggressive brushing
• Exposed tooth roots from receding gums
• Tooth decay (cavities)
• Cracked or chipped teeth
• Worn or leaking fillings
• Teeth grinding (bruxism) wearing down enamel
• Recent dental procedures (temporary sensitivity is normal)
• Gum disease causing root exposure

Diagnosing the Cause

We will take X-rays and examine your teeth to identify the cause of your sensitivity. The type of sensitivity (cold vs. heat, brief vs. lingering) helps us determine the cause. Brief sensitivity to cold is usually less serious than lingering sensitivity to heat, which may indicate pulp damage.

Treatment Options

Desensitizing toothpaste: Contains compounds that block pain signals — effective for mild sensitivity. Fluoride treatments: Strengthen enamel and reduce sensitivity. Bonding: Covers exposed root surfaces. Gum grafting: Covers exposed roots from receding gums. Night guard: Protects teeth from grinding. Root canal: For severe sensitivity caused by pulp damage.

Home Care for Sensitive Teeth

Use a soft-bristled toothbrush and brush gently. Use desensitizing toothpaste (Sensodyne, Pronamel). Avoid acidic foods and beverages. Rinse with fluoride mouthwash. Wear a night guard if you grind your teeth.
