Are Your Teeth Temperamental? Dealing With Sensitive Smiles

Are you overly sensitive? Relax, it has nothing to do with crying during life insurance commercials. Millions of adults struggle with hypersensitive teeth, which means they are sensitive to hot and cold temperatures, very sugary or acidic foods and drinks and vigorous tooth brushing. This kind of sensitivity is often called "dentin hypersensitivity."

Dentin is the tissue that makes up the core of each tooth. Above the gum line, dentin is protected with a coating of enamel. Unfortunately, as enamel is worn away or decayed, dentin becomes exposed and receptive to sensations that cause painful nerve responses. This can also occur as the result of receding gums, a common symptom of gum disease.

So, what causes sensitive teeth? A number of things may be to blame. Over-zealous brushing with a firm bristled tooth brush or abrasive toothpaste can lead to dentin hypersensitivity, as can gum disease, which is the result of poor brushing and flossing habits. Your diet may also play a role, as frequent consumption of acidic foods and drinks can chemically dissolve tooth enamel. Finally, abnormal wear on tooth surfaces from chronic clenching or grinding of teeth, nail biting and chewing on hard objects can lead to sensitive teeth. To avoid the problem, brush and floss daily to maintain healthy gums and protect dentin from exposure. Avoid vigorous tooth brushing with a hard-bristled toothbrush.

If you're already suffering from overly sensitive teeth, your best bet is to contact your dentist for guidance on dental hygiene. In the mean time, there are products that can help. Desensitizing toothpaste used in conjunction with a soft-bristled toothbrush can help. Toothpaste designed for those with sensitive teeth can reduce the pain associated with the condition after only a few days of use.

Preventive Dentistry

One of the simplest dental hygiene exercises you can do for yourself is something you've heard before and it bears repeating: floss.

Every 24 hours, bacteria contribute to a new batch of plaque. Brushing, no matter how well done, will not get all the "bugs," especially between teeth and where tooth meets gum tissue. Flossing before or after brushing should be a part of everyone's oral health care program. The kind of floss, waxed, unwaxed, tape, doesn't matter. Just choose the product you're comfortable with, and use it.

Maybe you never quite got the hang of flossing, or are a little out of practice. Here's a quick refresher course.

• Wrap about 18 inches of floss around your fingers; give yourself about five to six taut inches to work with. If the floss frays or builds up with debris, re-loop the floss and keep at it.
• Try starting on the upper molars, way in the back; they're most difficult to reach. Follow the curve of enamel on every surface you can, three to four passes each.
• Where teeth meet, you may have to gently pull the floss to the gum line. Avoid sawing motions as that may damage soft tissue.
• Proceed from the back teeth to the center front. Then repeat the process on the other side.
• Rinse, and there you are.

If you find all this tedious or feel you're "all thumbs," a floss threader can help. Your dental hygienist can show you how to handle one. Just ask for help.

And remember, any amount of time you spend on plaque removal is time well spent for better dental health. The more time the better. If you have more questions or for more information, just call your dentist.
