What Causes Tooth Sensitivity?

According to the Journal of the American Dental Association, sensitivity often stems from common dental issues that expose the sensitive parts of your teeth. These include:

  • Enamel Wear: Aggressive brushing or acidic foods can wear down your protective outer layer.

  • Exposed Roots: Gum recession or periodontal (gum) disease can leave tooth roots unprotected.

  • Physical Damage: A cracked tooth or worn-out fillings.

  • Tooth Decay: Cavities that have reached the inner layers of the tooth.¹

The Science: It’s All About Your "Pores"

Think of your teeth as having microscopic "pores" called dentinal tubules. When your enamel is damaged by any of the reasons we mentioned before, these tubules become exposed, allowing external stimuli to reach the nerves inside your tooth.

The good news? This is often avoidable with the right habits and products that protect your enamel.

Is It Too Late to Repair Sensitive Teeth?

Absolutely not. Relief depends on the cause and severity of your sensitivity. Here are the expert-recommended levels of care:

1. Daily At-Home Support

For light or occasional sensitivity, switching your daily toothpaste can make a significant difference. Using a product like Colgate Sensitive Complete Protection twice a day helps block the pain and protect your smile.

2. Professional In-Office Treatments

Sometimes, home treatment options aren't enough. During your routine dental visit, your hygienist can apply a treatment like Prevident Fluoride Varnish. This varnish remineralizes your enamel, making it much more resistant to the "sensitivity attacks" from food and drink.

3. Prescription-Strength Protection

For ongoing or more intense needs, your dentist may prescribe a high-strength formula like Prevident 5000ppm Sensitive. This ensures you are getting professional-grade protection every single day.

Don’t Let Sensitivity Change Your Life

You don't have to live with the "shock" of sensitive teeth. By identifying the cause and using the right resources, you can get back to the foods you love.

Talk to your dentist or dental hygienist at your next visit about which solution is right for you.
