BitewingX-RaysProvideEarlyDetectionofToothDecayinBackTeeth

One of the most widely used forms of dental imaging is the bitewing x-ray. So called because of the shape of the device that holds the exposable film a patient clenches between their back teeth, the bitewing x-ray is an effective means for detecting the earliest stages of tooth decay.

These early signs are small lesions on a tooth surface caused by mineral loss in the enamel. While we can identify them on front teeth through visual examination or bright lighting, they’re nearly impossible to see on the biting surfaces of back teeth. The bitewing x-ray solves this problem.

During the procedure, a narrow beam of x-rays is directed at the back teeth area. Since X-rays can transmit through solid matter, they pass through the teeth and gums to expose the film attached to the bitewing assembly.

X-rays pass through matter at different rates depending on the density of the tissue — a slower rate for harder tissues like teeth and bone and a faster rate for soft tissues like the gums. As a result, x-rays through teeth expose less of the film and appear as a lighter image than the gums. This difference is so precise even a tooth’s softer dentin appears slighter darker than its harder outer enamel.

This precision helps us identify decay lesions. Because the lesions on the enamel are less dense than the normal enamel, they’ll appear as dark spots. By detecting them at this stage we have a better chance for reversing the effects of decay or at least minimizing damage that’s already occurred.

Because x-rays emit radiation, there’s a natural concern about over-exposure and we go to great lengths to reduce it. Children may undergo a bitewing x-ray twice a year for developing teeth, while adults with healthy teeth are typically x-rayed just once a year. Advances in digital film and other technology have also helped lower the exposure rate.

Today’s standard 4-film bitewing x-ray produces about four days worth of what we receive on average from normal background radiation, so the health risk is quite negligible. The benefit, on the other hand, is much greater — the early detection of tooth decay could ultimately save a tooth.

WhyDentalCareisEvenMoreImportantWhenYourePregnant

Learning you’re pregnant can be a joyous moment. But it also means life is about to change as you focus on protecting you and your child from anything that endangers your health.

Because of these new concerns you might even hesitate about receiving dental care, especially involving anesthesia. But several medical organizations representing doctors, OB-GYN physicians and dentists wholeheartedly recommend continuing regular dental visits during pregnancy.

In fact, you should continue them because you’re pregnant: physical and hormonal changes during pregnancy could increase your risk of dental disease.

For, example, your consumption of carbohydrates (like sugar) could increase, which in turn increases your risk of tooth decay. You’ll also need to be more concerned about dental plaque, a thin bacterial film on your teeth that can cause disease. Hormonal changes during pregnancy may make you more sensitive to plaque, and thus more susceptible to disease — especially periodontal (gum) disease.

In fact, a specific form of gum disease called pregnancy gingivitis affects around 40% of expectant women at some point in their pregnancy. And if you already have gum disease, pregnancy could worsen it. Left untreated the disease could develop into more severe periodontitis, which may significantly damage your teeth’s support structures far below the gum line, leading to bone loss, which could result in the eventual loss of your teeth. Daily brushing and flossing, regular cleanings and checkups and, if your dentist prescribes it, antibacterial mouth rinses can help you stay ahead of it.

But what about other procedures while you’re pregnant? It may be best to wait on elective treatments for cosmetic purposes until after the baby is born. But some situations like deep tooth decay that could require a root canal treatment may become too serious to postpone.

Fortunately, several studies have shown it’s safe for pregnant women to undergo many dental procedures including tooth fillings or extractions. And receiving local anesthesia doesn’t appear to pose a danger either.

The important thing is to remain diligent with your own personal hygiene — brushing and flossing — and making other healthy choices like eating a nutritious diet. And be sure to let your dentist know about your pregnancy to help guide your dental treatment over the next few months.
