Sensitive About The Tooth

CBS News This Morning medical correspondent Dr. Emily Senay reports on a treatment for sensitive teeth.

The Issue: Sensitive Teeth
You're one of the 40 million Americans who has to think twice before drinking that morning cup of hot coffee or before downing a post-workout cold drink. You are unfortunate enough to have sensitive teeth. Why is this? What can you do?

The Cause:
Sensitivity can be caused by a breakdown in the enamel, which exposes the root surfaces.

The Solution:
It's called "Pain Free," and it's applied in a simple procedure by a dentist during a regular office visit. And without extensive dental work. It is a substance your dentist applies on your teeth with a cotton swab. There is no need for needles or any drilling. This treatment replaces the lost enamel with a chemical sealant. The cost: roughly US$50 per tooth.

Of course, prevention is always the best solution. Most dentists recommend an annual check-up and a brushing and flossing after every meal.
