X-ray imaging is such an intricate part of dentistry, we usually don't think twice about it. Without it, though, the fight against dental disease would be much harder.
At the same time, we can't forget that x-rays are a form of electromagnetic radiation that can penetrate human tissue. It's that very quality and the difference in the absorption rate between denser bone and teeth and softer diseased tissue that makes disease diagnosis possible.
But this same penetrative power can potentially harm the tissues it passes through. For that reason when practicing any form of x-ray diagnostics, dentists follow a principle known as ALARA, an acronym for "As Low As Reasonably Achievable." In lay terms ALARA means getting the most benefit from x-rays that we can with the lowest dose and exposure time possible.
While practicing ALARA with x-rays is important for patients of any age, it's especially so for children who are more sensitive to radiological energy given their smaller size and anatomy. We can't use the same settings, dosages or exposure times with them as with an adult.
To protect children, dentists have developed techniques and protocols that lessen their exposure time and rate, while still providing usable images for diagnosing disease. The bitewing is a good example of safe and effective pediatric x-ray imaging.
A bitewing is a plastic device holding exposable film that patients bite down on and hold in their mouth while x-raying. The x-rays pass through the teeth and gums and expose the film behind them on the bitewing. Using a bitewing we can capture a set of two to four radiographs to give us a comprehensive view of the back teeth, while exposing the child less radiation than they normally receive daily from background environmental sources.
This and other advances in equipment and digital imaging greatly reduce the amount of radiation patients receive during x-rays. If, though, you're still concerned about your child's x-ray exposure, talk with your dentist who can explain in more detail the x-ray safety protocols they follow. Just like you, they want your child to be as safe as possible while still benefiting from the diagnostic power of x-rays.

There are a few mouth conditions so rare most of us have never heard of them. Geographic tongue would fall into this category, affecting only one to three percent of the population. Even so, these irregular reddish patches resembling land masses on a map (hence the name) might be alarming at first glance—but they pose no danger and usually cause very little discomfort.
Geographic tongue is also known as benign migratory glossitis. As its clinical name implies, the unusual red patchy areas (often surrounded by a grayish white border) aren't cancerous nor contagious. The patches also appear to change shape and move around ("migrate") the tongue.
The reddish appearance comes from the temporary disappearance of tiny bumps on the tongue surface called papillae, which can leave the tongue smooth to the touch in affected areas. The lost papillae may reappear again a few hours or days later, and may occasionally disappear again. While it's not painful, you can experience a stinging or burning sensation emitting from these patchy areas.
We're not sure how and why geographic tongue erupts, but it's believed high emotional or psychological stress, hormonal imbalance or certain vitamin deficiencies might be factors in its cause. There may also be a link between it and psoriasis, a condition that can cause dry, itchy patches on the skin.
If you're one of the rare individuals who has episodes of geographic tongue, the good news is it's harmless, only mildly uncomfortable and usually temporary. The bad news, though, is that there's no known cure for the condition—but it can be managed to ease discomfort during outbreaks.
It's been found that highly acidic and spicy foods, as well as astringents like alcohol or some mouthrinses, can increase the level of discomfort. By avoiding these or similar foods or substances, you can reduce the irritation. Your dentist may also be able to help by prescribing anesthetic mouthrinses, antihistamines or steroid ointments.
For the most part, you'll simply have to wait it out. Other than the mild, physical discomfort, the worst part is often simply the appearance of the tongue. But by watching your diet and other habits, and with a little help from us, you can cope with these irritations when it occurs.

Exchanging passionate kisses with big-screen star Jennifer Lawrence might sound like a dream come true. But according to Liam Hemsworth, her Hunger Games co-star, it could also be a nightmare… because J.Law’s breath wasn’t always fresh. “Anytime I had to kiss Jennifer was pretty uncomfortable,” Hemsworth said on The Tonight Show.
Lawrence said the problem resulted from her inadvertently consuming tuna or garlic before the lip-locking scenes; fortunately, the two stars were able to share a laugh about it later. But for many people, bad breath is no joke. It can lead to embarrassment and social difficulties — and it occasionally signifies a more serious problem. So what causes bad breath, and what can you do about it?
In 9 out of 10 cases, bad breath originates in the mouth. (In rare situations, it results from a medical issue in another part of the body, such as liver disease or a lung infection.) The foul odors associated with bad breath can be temporarily masked with mouthwash or breath mints — but in order to really control it, we need to find out exactly what’s causing the problem, and address its source.
As Lawrence and Hemsworth found out, some foods and beverages can indeed cause a malodorous mouth. Onions, garlic, alcohol and coffee are deservedly blamed for this. Tobacco products are also big contributors to bad breath — which is one more reason to quit. But fasting isn’t the answer either: stop eating for long enough and another set of foul-smelling substances will be released. Your best bet is to stay well hydrated and snack on crisp, fresh foods like celery, apples or parsley.
And speaking of hydration (or the lack of it): Mouth dryness and reduced salivary flow during the nighttime hours is what causes “morning breath.” Certain health issues and some medications can also cause “dry mouth,” or xerostomia. Drinking plenty of water can encourage the production of healthy saliva — but if that’s not enough, tell us about it: We may recommend switching medications (if possible), chewing xylitol gum or using a saliva substitute.
Finally, maintaining excellent oral hygiene is a great way to avoid bad breath. The goal of oral hygiene is to control the harmful bacteria that live in your mouth. These microorganisms can cause gum disease, tooth decay, and bad breath — so keeping them in check is good for your overall oral health. Remember to brush twice and floss once daily, stay away from sugary foods and beverages, and visit the dental office regularly for checkups and professional cleanings.
So did J.Law apologize for the malodorous makeout session? Not exactly. “[For] Bradley Cooper, Christian Bale, yeah, I’ll brush my teeth,” she laughed.
Hemsworth jokingly agreed: “If I was kissing Christian Bale I probably would have brushed my teeth too. With you, it’s like, ‘Eh. Whatever.’”
