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.

Each year, the National Safety Council recognizes June as National Safety Month. It's the perfect time to focus on safety: With summer temperatures heating up, so do sports and outdoor activities—and, unfortunately, the risk of accidents. As the old Boy Scout motto goes, everyone should "be prepared." And while that means watching out for sunburn, poison ivy or traveling hazards, it also means being alert for potential tooth injuries.
Even during casual recreational sports, an unintentional hit to the face or jaw could chip, move or, worse yet, knock a tooth out completely. As with any other aspect of safety, prevention should be at the top of your list when it comes to dental injuries. In that regard, anyone involved in a contact sport or other high-risk activity should wear a mouthguard. This device absorbs much of the force generated during a hard impact to the face or jaw that might otherwise affect the teeth.
Mouthguards fall into two basic categories. The first are retail guards available at sporting goods stores and many pharmacies, most commonly "boil and bite" guards. They're so named because a wearer first softens them with very hot water and then bites down on them to personalize their fit. Once cooled, the mouthguard will maintain its shape. While reducing the severity of impact injuries, these retail mouthguards can be bulky and uncomfortable to wear.
The second category, a custom mouthguard created by a dentist, offers a sleeker, more comfortable fit. These guards are based on a direct impression of the wearer's mouth that we take at the dental office. Although any mouthguard is better than no mouthguard, a 2018 study confirmed that custom-made mouthguards from the dental office perform better than the kind bought in a drug store or sporting goods store.
Summer is prime time for creating cherished family memories. With a little dental injury prevention knowledge, you can help make sure those summer memories are happy ones.

Dairy foods have played a role in human diets for thousands of years. More than one kid—whether millennia ago on the Mesopotamian plains or today in an American suburb—has been told to drink their milk to grow strong. This is because milk and other dairy products contain vitamins and minerals that are essential for a healthy body, including healthy teeth and gums. In honor of National Dairy Month in June, here are four ways dairy boosts your oral health:
Dental-friendly vitamins, minerals and proteins. Dairy products are an excellent source of many vitamins and minerals that are important for good dental health. They are packed with calcium and phosphorus, two minerals that work together to strengthen tooth enamel. In addition to the vitamins they contain naturally, milk and yogurt are fortified with vitamin D, which aids in calcium and phosphorus absorption; cheese contains a small amount of vitamin D naturally. What's more, dairy proteins have been shown to prevent or reduce the erosion of tooth enamel and strengthen the connective tissues that hold teeth in place.
Lactose: a more tooth-friendly sugar. Sugars like sucrose or high fructose corn syrup, which are routinely added to processed foods, are a primary trigger for tooth decay. This is because certain oral bacteria consume sugar, producing acid as a by-product. The acid weakens tooth enamel, eventually resulting in cavities. Dairy products—at least those without added sugar—are naturally low in sugar, and the sugar they contain, lactose, results in less acid production than other common sugars.
The decay-busting power of cheese. We know that high acidity in the mouth is a major factor in decay development. But cheese is low in acidity, and a quick bite of it right after eating a sugary snack could help raise the mouth's pH out of the danger zone. Cheeses are also rich in calcium, which could help preserve that important mineral's balance in tooth enamel.
Dairy for gum health. A study published in the Journal of Periodontology found that people who regularly consumed dairy products had a lower incidence of gum disease than those who did not. And since gum health is related to the overall health, it's important to do all we can to prevent and manage gum disease.
For those who cannot or choose not to consume dairy products, there are other foods that supply calcium naturally, such as beans, nuts and leafy greens—and many other foods are fortified with calcium, vitamin D and other nutrients. It may be wise to take a multivitamin or calcium with vitamin D as a supplement as well.
