It's difficult to measure how x-ray imaging has transformed dentistry since its use became prominent a half century ago. As equipment and methods standardized, the technology revolutionized the way we diagnose tooth decay and other mouth-related issues.
One of the more useful of these methods is called the bitewing x-ray. The term comes from the shape of the device a patient holds between their teeth with the film attached on the side toward their tongue. We direct the x-ray beam to the outside of the patient's cheek, where it passes through the teeth to expose on the film. Its particular design provides clearer images since the patient's bite helps keep the film still and distortion-free, making it easier to view signs of early tooth decay.
Bitewing x-rays usually consist of four films, two on either side of the mouth, necessary to capture all of the teeth (children with smaller jaws, however, often only require one film per side). How frequently they're conducted depends on a number of factors, including the patient's age: children or young adolescents are usually filmed more frequently than adults, usually every six to twelve months. Frequency also depends on a patient's particular decay risk — the higher the risk the more frequent the x-ray.
Regardless of how often they're performed, a similar application principle applies with bitewing x-rays as with any other radiological method: As Low As Reasonably Achievable (ALARA). With the ALARA principle in other words, we're looking for that sweet spot where we're able to detect the earliest stages of dental disease with the least amount of radiation exposure.
Bitewings fit this principle well: a patient receives only a fraction of the radiation exposure from a four-film bitewing as they do from a daily dose of environmental radiation. Factor in new digital technology that reduces exposure rates and bitewings pose virtually no health risk to patients, especially if conducted in a prudent manner.
The benefits are well worth it. Thanks to bitewing x-rays we may be able to diagnose decay early and stop it before it causes you or your family member extensive tooth damage.
It might seem that supermodels have a fairly easy life — except for the fact that they are expected to look perfect whenever they’re in front of a camera. Sometimes that’s easy — but other times, it can be pretty difficult. Just ask Chrissy Teigen: Recently, she was in Bangkok, Thailand, filming a restaurant scene for the TV travel series The Getaway, when some temporary restorations (bonding) on her teeth ended up in her food.
As she recounted in an interview, “I was… like, ‘Oh my god, is my tooth going to fall out on camera?’ This is going to be horrible.” Yet despite the mishap, Teigen managed to finish the scene — and to keep looking flawless. What caused her dental dilemma? “I had chipped my front tooth so I had temporaries in,” she explained. “I’m a grinder. I grind like crazy at night time. I had temporary teeth in that I actually ground off on the flight to Thailand.”
Like stress, teeth grinding is a problem that can affect anyone, supermodel or not. In fact, the two conditions are often related. Sometimes, the habit of bruxism (teeth clenching and grinding) occurs during the day, when you’re trying to cope with a stressful situation. Other times, it can occur at night — even while you’re asleep, so you retain no memory of it in the morning. Either way, it’s a behavior that can seriously damage your teeth.
When teeth are constantly subjected to the extreme forces produced by clenching and grinding, their hard outer covering (enamel) can quickly start to wear away. In time, teeth can become chipped, worn down — even loose! Any dental work on those teeth, such as fillings, bonded areas and crowns, may also be damaged, start to crumble or fall out. Your teeth may become extremely sensitive to hot and cold because of the lack of sufficient enamel. Bruxism can also result in headaches and jaw pain, due in part to the stress placed on muscles of the jaw and face.
You may not be aware of your own teeth-grinding behavior — but if you notice these symptoms, you might have a grinding problem. Likewise, after your routine dental exam, we may alert you to the possibility that you’re a “bruxer.” So what can you do about teeth clenching and grinding?
We can suggest a number of treatments, ranging from lifestyle changes to dental appliances or procedures. Becoming aware of the behavior is a good first step; in some cases, that may be all that’s needed to start controlling the habit. Finding healthy ways to relieve stress — meditation, relaxation, a warm bath and a soothing environment — may also help. If nighttime grinding keeps occurring, an “occlusal guard” (nightguard) may be recommended. This comfortable device is worn in the mouth at night, to protect teeth from damage. If a minor bite problem exists, it can sometimes be remedied with a simple procedure; in more complex situations, orthodontic work might be recommended.
Teeth grinding at night can damage your smile — but you don’t have to take it lying down! If you have questions about bruxism, please contact us or schedule an appointment for a consultation.
