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.
You probably know practicing healthy dietary and lifestyle habits can help prevent tooth decay and periodontal (gum) disease. But good habits could also lower your risk for a more dangerous type of disease — oral cancer.
There are several risk factors for oral cancer, including those you can't do much about like your genetic makeup or unknown elements in the environment. But there are factors you can influence with your actions.
You're probably familiar with the links between tobacco use (both smoked and smokeless) and oral cancer. But excessive alcohol use could also increase your risk, as can risky sexual behavior that could expose you to human papilloma virus (HPV) 16.
And what you eat — or don't eat — could also influence your cancer risk. Research over the last half century has uncovered a link between diet and cancer. Cancer development seems to begin with damage to DNA, the genetic material that “tells” each of our cells what it is and what it does in the body. Substances called carcinogens found in the environment — including the foods we eat — can damage our DNA and open the door for cancer to development.
But some foods also contain elements that protect our DNA from carcinogenic damage. Some of these are known as antioxidants, which protect cells from unstable molecules called free radicals. You'll find antioxidants, as well as other protective substances like fiber, vitamins and lycopene in plant-based foods, particularly fruits and vegetables.
Eating a plant-based diet also means you'll eat fewer foods that contribute to the rise of free radicals like saturated fat, animal protein and nitrates (a chemical that occurs in some food processing). A healthy diet, along with quitting tobacco use and moderating alcohol consumption, will help not only preventing decay or gum disease, it will also drastically lower your risk for oral cancer.

When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.
"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."
Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!
“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”
Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.
Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.
Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.
Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.
