Coping With Dental Phobia

Does the thought of succumbing to the dentist's chair send a jolt of anxiety through your body? When it comes to triggering a fear response, few things can set people off like an upcoming trip to the dentist. That fear can set in early.  Threatening comments from a parent, such as "If you don't brush your teeth, you'll have to go to the dentist," can leave a lasting negative impression.

2. How long do the teeth whitening effects last?

Teeth whitening is not permanent. People who expose their teeth to foods and beverages that cause staining may see the whiteness start to fade in as little as one month. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed.

3. Do teeth whiteners damage tooth enamel?

Studies of teeth whitening products using 10% carbamide peroxide showed no effect on the hardness or mineral content of a tooth's enamel surface.

4. Do teeth whiteners damage existing dental restorations?

Over 10 years of clinical use of teeth whitening products containing 10% carbamide peroxide have not shown any damage to existing fillings. The issue is not "damage" to existing restorations; rather, keep in mind that existing restorations such as tooth-colored fillings, crowns, bonding, veneers, and bridges do not lighten. This means that any pre-existing dental work may need to be replaced to match the new tooth shade achieved in the natural teeth, should a bleaching process proceed.

5. Do teeth whiteners damage a tooth's nerve?

There's no evidence to date that the teeth whitening process has a harmful effect on the health of a tooth's nerve. One study reported that at both a 4.5- and 7-year follow up, no individual who used a teeth whitening system needed a root canal procedure on any teeth that had been whitened.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.
