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.

Forks are for Eating: Dental Hygiene Across the Pond

From Austin Powers to The Simpsons, American pop culture has heckled the British for their allegedly bad teeth for years. Let's face it - even Prince Charles could use a good orthodontist. Now it looks like comedians will have fresh material, thanks to a national survey that polled Brits on their dental habits.

An overwhelming number of respondents admitted to cleaning their teeth with just about everything but floss, opting for everyday household tools instead. Nontraditional tooth picks included: screw drivers, earrings, forks, scissors and (wait for it) knives. (Maybe they should consider putting restrictions on the use of ice picks.) To top it off, about half reported they don't bother cleaning food out from between their teeth at all. Yikes! Needless to say the English dental community has admittedly fallen behind in dental education.

While it's easy to laugh at our friends across the pond, the truth is a number of Americans aren't doing much better when it comes to oral hygiene. Gum disease and tooth decay are two potentially serious conditions frequently overlooked by the American press. (Maybe they're too busy critiquing jolly England's smiles.) They are also linked to other health problems, including heart disease and low birth weight.

In order to maintain your own dental health, it's important to brush and floss everyday. If you find particularly tricky debris stuck between your teeth, skip using your PDA's stylus to dig it out. Your best option is a wood (and therefore flexible) tooth pick or dental ribbon, which is smoother than floss. Tying a small knot in it can help dislodge larger pieces of food.

So, the next time you hear somebody crack a joke at the queen's expense, consider your own flossing habits. And for Pete's sake, never use anything to clean your teeth and gums that wasn't designed for that purpose!
