When it comes to our children’s safety, there isn’t much nowadays that isn’t under scrutiny. Whether food, clothing, toys and more, we ask the same question: can it be harmful to children?
That also includes tried and true healthcare practices. One in particular, the routine x-ray, has been an integral part of dental care for nearly a century. As a means for detecting tooth decay much earlier than by sight, it has without a doubt helped save billions of teeth.
But is it safe for children? The reason to ask is because x-rays are an invisible form of electromagnetic radiation that can penetrate human tissue. As with other forms of radiation, elevated or frequent exposure to x-rays could damage tissue and increase the future risk of cancer.
But while there is potential for harm, dentists take great care to never expose patients, especially children, to that level or frequency of radiation. They incorporate a number of safeguards based on a principle followed by all healthcare professionals in regard to x-rays called ALARA, an acronym for “as low as reasonably achievable.” This means dentists and physicians use as low an exposure of x-ray energy as is needed to achieve a reasonable beneficial outcome. In dentistry, that’s identifying and treating tooth decay.
X-ray equipment advances are a good example of ALARA in action. Digital imaging, which has largely replaced film, requires less x-ray radiation for the same results than its older counterpart. Camera equipment has also become more efficient, with modern units containing lower settings for children to ensure the proper amount of exposure.
Dentists are also careful how often they take x-ray images with their patients, only doing so when absolutely necessary. As a result, dental patients by and large experience lower dosages of x-ray radiation in a year than they receive from natural radiation background sources found every day in the environment.
Dentists are committed to using x-ray technology in as safe and beneficial a way as possible. Still, if you have concerns please feel free to discuss it further with your dental provider. Both of you have the same goal—that your children have both healthy mouths and healthy bodies for the rest of their lives.

Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
It’s true — thumb sucking beyond age 4 can cause bite problems for permanent teeth. But prolonged thumb sucking is just one of a number of possible contributing factors for a bad bite (malocclusion). A dentist must identify all the factors involved when a bad bite is present — their involvement is essential for a successful treatment outcome.
A fairly benign habit for infants and toddlers, thumb sucking is related to an “infantile swallowing pattern” young children use by thrusting their tongues forward between the upper and lower teeth when they swallow. Around age 4, though, they usually transition to an adult swallowing pattern in which the tongue rests on the roof of the mouth just behind the front teeth. Thumb sucking stops for most children around the same time.
Thumb sucking beyond this age, though, can put increased pressure on incoming permanent teeth pushing them forward. This could lead to an “open bite” in which the upper and lower teeth don’t meet when the jaws are closed. The tongue may also continue to thrust forward when swallowing to seal the resulting gap, which further reinforces the open bite.
Before treating the bite with braces, we must first address the thumb sucking and improper tongue placement when swallowing — if either isn’t corrected the teeth could gradually revert to their previous positions after the braces come off. Besides behavioral incentives, we can also employ a thin metal appliance called a “tongue crib” placed behind the upper and lower incisors. A tongue crib discourages thumb sucking and makes it more difficult for the tongue to rest within the open bite gap when swallowing, which helps retrain it to a more normal position.
An open bite can also occur if the jaws develop with too much vertical growth. Like thumb sucking and improper tongue placement, abnormal jaw growth could ultimately cause orthodontic treatment to fail. In this case, though, surgery may be necessary to correct the jaw structure.
With all these possible variables, our first step needs to be a thorough orthodontic exam that identifies all the cause factors for your child’s specific malocclusion. Knowing if and how thumb sucking may have contributed to the poor bite will help us design a treatment strategy that’s successful.
