ThereAreaLotofBacteriainYourMouthbutOnlyaFewMeanYouHarm

Say “bacteria,” especially in the same sentence with “disease” or “infection,” and you may trigger an immediate stampede for the hand sanitizer. The last thing most people want is to come in contact with these “menacing” microorganisms.

If that describes you, however, you’re too late. If you’re of adult age, there are already 100 trillion of these single-celled organisms in and on your body, outnumbering your own cells 10 to 1. But don’t panic: Of these 10,000-plus species only a handful can cause you harm—most are either harmless or beneficial, including in your mouth.

Thanks to recent research, we know quite a bit about the different kinds of bacteria in the mouth and what they’re doing. We’ve also learned that the mouth’s microbiome (the interactive environment of microscopic organisms in a particular location) develops over time, especially during our formative years. New mothers, for example, pass on hundreds of beneficial species of bacteria to their babies via their breast milk.

As our exposure to different bacteria grows, our immune system is also developing—not only fighting bacteria that pose a threat, but also learning to recognize benevolent species. All these factors over time result in a sophisticated, interrelated bacterial environment unique to every individual.

Of course, it isn’t all sweetness and light in this microscopic world. The few harmful oral bacteria, especially those that trigger tooth decay or periodontal (gum) disease, can cause enormous, irreparable damage to the teeth and gums. It’s our goal as dentists to treat these diseases and, when necessary, fight against harmful microorganisms with antibacterial agents and antibiotics.

But our growing knowledge of this “secret world” of bacteria is now influencing how we approach dental treatment. A generalized application of antibiotics, for example, could harm beneficial bacteria as well as harmful ones. In trying to do good we may run the risk of disrupting the mouth’s microbiome balance—with adverse results on a patient’s long-term oral health.

The treatment strategies of the future will take this into account. While stopping dental disease will remain the top priority, the treatments of the future will seek to do it without harming the delicate balance of the mouth’s microbiome.

HeresWhatYouNeedtoKnowAboutTeethWhitening

Getting a smile upgrade doesn’t necessarily require extensive dental work. You might be able to change your appearance for the better with teeth whitening.

This technique employs a bleaching solution that brightens dull enamel, the outermost layer of teeth. It isn’t a permanent fix, but if cared for properly your brighter smile could last two years or more.

Here’s what you need to know about this proven smile brightener.

Know your options. Enamel whitening is usually obtained in one of three ways: a dentist performing the procedure in-office; at home using custom trays created by a dentist; or at home with an over-the-counter whitening product. The in-office option is the most expensive—but since dentists use a stronger bleaching solution, your brighter tint may last longer and dentists can control the degree of whiteness better.

Know your preferences. That last point is important if you’re looking for a particular look. Teeth whitening can give you a dazzling “Hollywood” smile or one that’s a bit more subtle. It all depends on your lifestyle and personal preferences. Because of their advanced techniques and equipment, you may have better chances getting the look you want from your dentist rather than by doing it yourself.

Know your limitations. This type of teeth whitening won’t work if the staining originates within the teeth—for that you’ll need an invasive procedure only a dentist can perform. You’ll also want to be careful with any whitening if you have dental work like crowns, veneers or fillings: the bleaching solution won’t alter these materials’ color, which could make them stand out beside whitened natural teeth. And if you have diseased teeth and gums, those need to be treated first before any cosmetic procedures like whitening.

Teeth whitening is a great way to take years off a smile. Even if you plan to whiten your teeth at home see your dentist first for a complete examination and helpful tips on products and techniques.

DontPanicOverYourChildsTeethGrindingbutDoKeepanEyeonIt

First the bad news: Those nightly hair-raising sounds are indeed coming from your child’s bedroom—from your child. It’s the result of them grinding their teeth while they sleep.

But here’s the good news: the only likely harm is a lack of sleep members of your household might experience because of it. Teeth grinding is so prevalent among pre-teen children that many healthcare professionals consider it normal. But that doesn’t mean it can’t become a problem, so it’s worth monitoring.

Teeth grinding is part of a family of dental habits known as bruxism. It involves any involuntary movement of the teeth and jaws outside of their intended functions not associated with chewing, speaking or swallowing. Our main concern with any bruxism is the possibility for generating stronger biting forces than normal that could damage teeth and gums and contribute to jaw joint problems.

Teeth grinding can occur in adulthood, with stress seeming to be the major trigger for it. With children, though, it’s believed to be mainly caused by an immaturity of the child’s neuromuscular process that controls chewing. As this matures, most children will tend to outgrow the habit none the worse for wear.

But there are pediatric cases in which the generated biting forces are strong enough to cause damage. Teeth grinding is also prevalent in children who snore or breathe through their mouths, which could be a sign of a serious health condition called obstructive sleep apnea. And certain medications used to treat depression and attention deficit disorder (ADHD) may also contribute to teeth grinding.

Most of the time we can simply let the habit run its course. If, however, the child begins to experience abnormal tooth wear, headaches, jaw pain or other issues believed caused by teeth grinding, we may need to intervene. This could include a plastic night guard the child wears during sleep that prevents the teeth from making solid contact during grinding episodes. And children with signs of airway obstruction should be evaluated by an ear, nose and throat specialist.

It can be irritating or even distressing. But your child’s teeth grinding doesn’t mean you should be alarmed—only that you should keep your eye on it.
