When you think orthodontics, you may instantly picture braces or clear aligners worn by teenagers or adults. But there’s more to orthodontics than correcting fully developed malocclusions (poor bites). It’s also possible to intervene and potentially reduce a malocclusion’s future severity and cost well beforehand.
Known as interceptive orthodontics, these treatments help guide jaw growth in children while mouth structures are still developing and more pliable. But timing is critical: waiting until late childhood or puberty could be too late.
For example, we can influence an upper jaw developing too narrowly (which can cause erupting teeth to crowd each other) with an expander appliance placed in the roof of the mouth. The expander exerts slight, outward pressure on the upper jaw bones. Because the bones haven’t yet fused as they will later, the pressure maintains a gap between them that fills with additional bone that eventually widens the jaw.
Functional appliances like the Herbst appliance influence muscle and bone development in the jaws to eventually reshape and reposition them. The Herbst appliance utilizes a set of metal hinges connected to the top and bottom jaws; when the patient opens and closes their jaws the hinges encourage the lower jaw to move (and eventually grow) forward. If successful, it could help a patient avoid more invasive treatments like tooth extraction or jaw surgery.
Some interceptive objectives are quite simple in comparison like preserving the space created by a prematurely lost primary tooth. If a child loses a primary tooth before the incoming permanent tooth is ready to erupt, the nearby teeth can drift into the empty space. Without enough room, the permanent tooth could erupt out of position. We can hold the space with a simple loop device known as a space maintainer: usually made of acrylic or metal, the device fits between adjacent teeth and prevents them from drifting into the space until the permanent tooth is ready to come in.
Interceptive orthodontics can have a positive impact on your child’s jaw development, now and in the future. For these techniques to be effective, though, they must begin early, so be sure your child has a complete orthodontic evaluation beginning around age 7. You may be able to head off future bite problems before they happen.
Your child’s dental care wouldn’t be the same without x-ray imaging. It’s one of our best tools for finding and treating tooth decay.
But since x-rays emit radiation, is your child in any danger when they’re exposed?
X-rays, an invisible form of electromagnetic energy, will form images on exposed film after passing through the body. Because it takes longer for x-rays to pass through dense tissue like teeth and bones, the corresponding areas appear lighter on the film than less dense tissue like the gums. We can detect decay because the diseased tooth structure is less dense and thus appears darker against healthier tooth structure.
The downside of x-rays, though, is the radiation they emit could potentially alter cell structure and increase the risk of future cancer, especially with children. That’s why we follow a principle known as ALARA when using x-ray imaging. ALARA is an acronym for “as low as reasonably achievable,” meaning the doses for an x-ray session will be as low as possible while still gaining the most benefit.
Advances in technology, particularly the development of digital processing, has helped reduce the amount of radiation exposure. We’re also careful with what types of x-rays we use. The most common type is the bitewing, a device with the film attached to a long piece of plastic that the child holds in their mouth while biting down.
Depending on the number of our patient’s teeth, we can usually get a comprehensive view with two to four bitewings. A typical bitewing session exposes them to less radiation than what they’re receiving from natural environmental background sources each day.
Keeping the exposure as low and as less frequent as possible greatly reduces health risks while still getting the full benefit of early decay detection. Still, if you have concerns about your child’s x-ray exposure, we’ll be happy to discuss our approach and all the precautions we take using x-ray imaging.

Tooth decay is an ever present danger for your baby’s developing teeth. It begins with disease-causing bacteria feasting on leftover sugar, producing high levels of oral acid that slowly dissolves the teeth’s protective enamel. The softened enamel then becomes an open door for decay to infect the tooth.
Meanwhile, those bacteria continue to eat and produce acid….
So how can you stop this devastating cycle? Besides daily oral hygiene and regular dental visits, the most important thing you can do is deprive bacteria in your baby’s mouth of sugar through limiting their consumption of it. This means you’ll first need to identify the different sources of sugar available to your baby—and some of them might surprise you.
Here, then, are 3 not-so-obvious sugar sources your baby might be consuming.
During feeding. If you’re breast-feeding, you may not think this is causing a sugar problem for your baby. True, breast milk by itself doesn’t promote decay: it’s the combination of it with other sugar-rich foods and liquids the baby might be consuming as they get older. Together this could significantly increase their risk of pediatric tooth decay (also known as early childhood caries or ECC). So, be careful to limit sugar in other things they’re eating or drinking in addition to nursing.
24/7 Baby bottles and pacifiers. To calm infants at nap or sleep time, parents or caregivers often use bottles filled with sweet liquids or pacifiers dipped in jam, syrup or sugar. This practice increases decay risk from both the added sugar and its constant availability to bacteria in the mouth around the clock. Instead, avoid this practice and limit any sugary foods or liquids to mealtimes.
Medications. Some medications an infant may be taking for a chronic illness may contain small amounts of sugar. Additionally, medications like antihistamines can reduce the production of saliva that’s needed to neutralize acid after meals. If your child is on medication, ask your healthcare provider about its dental effects and if there are any sugar-free alternatives. Be sure to keep up daily brushing and flossing and regular dental visits too.
Limiting your baby’s sugar intake is critical in preventing tooth decay. It’s one of the most important things you can do to protect their dental health.
