It’s important for your child’s current and future health that we watch out for tooth decay. Taking x-rays is a critical part of staying one step ahead of this common disease.
But while x-ray imaging is commonplace, we can’t forget it’s still a form of radiation that could be potentially harmful, especially for a child whose tissues are rapidly developing. We must, therefore, carefully weigh the potential benefits against risk.
This concern has given birth to an important principle in the use of x-rays known as ALARA, an acronym for “As Low As Reasonably Achievable.” In basic terms, we want to use the lowest amount of x-ray energy for the shortest period of time to gain the most effectiveness in diagnosing tooth decay and other conditions.
A good example of this principle is a common type of radiograph known as a bitewing. The exposable x-ray film is attached to a plastic devise that looks like a wing; the patient bites down on it to hold it in place while the x-ray exposure takes place. Depending on the number of teeth in a child’s mouth, an appointment usually involves 2 to 4 films, and children are typically spaced at six months apart. Frequency of x-rays depends on your child’s tooth decay risk: lower risk, less need for frequent intervals.
Each bitewing exposes the child to 2 microsieverts, the standard unit for radiation measurement. This amount of radiation is relatively low: by contrast, we’re all exposed to 10 microsieverts of background radiation (natural radiation occurring in the environment) every day or 3,600 microsieverts annually. Even two appointments of four bitewings each year is a fraction of a percent of the background radiation we’re exposed to in the same year.
This conservative use of x-rays is well within safe parameters for children. As x-ray technology continues to advance (as with the development of digital imaging) we anticipate the exposure rate to diminish even more. Prudently used, x-rays remain one of our best tools for ensuring your child’s teeth are healthy and developing normally.

So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.
