X-rays are so interwoven into dental care that we often don't think twice about them. Even so, we shouldn't take this invisible form of radiation lightly—regular exposure at high levels can affect the human body, especially in children.
The ability of x-rays to pass through tissue greatly improves our ability to diagnose tooth decay and other dental diseases. But x-rays can also potentially harm those same tissues. Because children are more sensitive to x-ray energy, they run a greater risk for cellular damage that could lead to cancer later in life.
In reality, though, these potential risks from x-rays are extremely low—so low, in fact, dental professionals regard their use as altogether safe for children. Here's why.
The ALARA principle. Dentists and other healthcare providers perform x-ray diagnostics based on a principle known as ALARA (“As low as reasonably achievable”). This means dentists only utilize x-rays to gain the most diagnostic benefit at the lowest amounts of radiation exposure. As such, ALARA guides both the development of x-ray equipment and the protocols involved in using them.
Equipment advances. Today's x-ray devices are safer and more efficient, restricting x-ray emissions to a single beam without scattering radiation into the environment. A child's radiation exposure is further lowered with the use of digital x-rays, which produce images in less time than conventional film. Because of these and other advances, children are exposed to less radiation during x-rays than what they typically receive in a day from the outside environment.
Safe practices. Following the ALARA principle, dentists are quite conservative in their use of x-rays in children. The most common means of x-ray is the bitewing, which captures images primarily of the back teeth that are more prone to decay. Bitewings, which require a lower x-ray dosage than a full mouth x-ray, are usually spaced at least six months apart or longer depending on a child's risk for dental disease.
The efficiency of modern radiographic equipment coupled with their judicious use has drastically reduced the amount of x-ray radiation to which a child may be exposed, thus lowering their risk of future health issues. The benefit for saving a child's teeth from disease is well worth their use.

Emma Roberts, star of American Horror Story (and niece of actress Julia Roberts), welcomed her first child at the end of 2020. She confessed that her love of sweets made pregnancy challenging. She couldn't get enough of cupcakes with sprinkles and a Salt & Straw ice cream flavor called The Great Candycopia. But Roberts isn't unique. Hormonal changes in pregnancy often bring heightened cravings for certain foods. Unfortunately, this can increase an expectant mother's risk for dental disease, especially if they're consuming more sugary foods.
In fact, around four in ten expectant women will develop a form of periodontal disease called pregnancy gingivitis. It begins with dental plaque, a thin film that forms on tooth surfaces filled with oral bacteria that can infect the gums. And what do these bacteria love to eat? Yep—sugar, the same thing many women crave during pregnancy.
So, if you're expecting a baby, what can you do to minimize your risk for dental disease?
Practice oral hygiene. Removing dental plaque by brushing and flossing daily is the most important thing you can do personally to prevent both tooth decay and gum disease. It's even more important given the physical and hormonal changes that occur when you're pregnant. Be sure, then, that you're diligent about brushing and flossing every day without fail.
Control your sugar intake. If you have strong cravings for sweets, cutting back may be about as easy as stopping an elephant on a rampage through the jungle. But do give your best effort to eating more dairy- and protein-rich foods rather than refined carbohydrates like pastries or candies. Not only will reducing sugar help you avoid dental disease, these other foods will help strengthen your teeth.
Maintain regular dental visits. Seeing us for regular cleanings further reduces your disease risk. We can clean your teeth of any plaque deposits you might have missed, especially hardened plaque called tartar that's nearly impossible to remove with brushing and flossing. We'll also monitor your teeth and gums for any developing disease that requires further treatment.
Undergo needed treatments. Concerned for their baby's safety, many expectant mothers are hesitant about undergoing dental procedures. But both the American Congress of Obstetricians and Gynecologists and the American Dental Association endorse necessary dental treatments during pregnancy, even if they include local anesthesia. We will make you have only a safe type of anesthesia, and we can advise you when it is prudent to postpone certain treatments, such as some elective procedures, until after the baby is born.
Emma Roberts got through a healthy pregnancy—cravings and all—and is now enjoying her new baby boy. Whether you're a celebrity like Emma Roberts or not, expecting a baby is an exciting life moment. Follow these tips to keep your teeth and gums healthy throughout your pregnancy, and be sure to let the dental team know of your pregnancy before any treatment.If you would like more information about dental care during pregnancy, please contact us or schedule a consultation.

“Orthodontic treatment” and “braces” almost seem like synonymous terms. But while braces certainly are orthodontic, it isn't the only tool in an orthodontist's toolkit.
A good example is a device is known as a Herbst appliance. It's used in situations where the upper jaw is outpacing the growth and development of the lower jaw during childhood. If not corrected, this could cause the top teeth to protrude abnormally beyond the lower teeth.
The Herbst appliance gently and gradually coaxes the lower jaw to grow in a more forward direction, thus “catching up” with the upper jaw. The top part of the device consists of two metal tubes hinged to small elastic bands, which are cemented to the cheek side of the upper back teeth (molars), one on either side of the jaw.
Two smaller tubes are attached in like fashion to the lower teeth, and then inserted into the larger tubes. As the lower jaw moves, the smaller tubes move within the larger to create pressure that gently pushes the jaw forward. Over time, this can sync the growth progress of both the upper and lower jaws, and reduce the chances of a poor bite.
For best results, a Herbst appliance is usually placed to coincide with a child's most rapid period of jaw growth, usually between 11 and 14. They could be placed as early as 8 or 9, however, in situations where the front teeth are already protruding well beyond the lips. In any event, the goal is to positively influence the growth of the lower jaw to alleviate or at least minimize the need for future orthodontic treatment.
As a fixed device, there's no need for a child or parent to tend to it as with other methods, like orthodontic headwear worn in conjunction with braces. A Herbst appliance can, however, alter the normal sensations associated with eating, swallowing and speaking, which may take a little adjustment time for the child. Wearers will also need to be extra vigilant with daily brushing and flossing because of a higher risk of tooth decay.
These, though, are minor inconveniences compared with the benefit of improved bite development. As such, a Herbst appliance could be a positive investment in your child's dental future.
