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.

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.
"Mom, my tooth hurts" isn't something you look forward to hearing your child say. But tooth pain is as common as other childhood ailments, so you may have to face it. Here are a few simple steps to make it easier.
First, ask your child where in the mouth it hurts and, if they can, tell you how long it's been hurting. Children's memories aren't always accurate, but you can still get a general idea that you can communicate with your dentist if you take them in.
Next, look in their mouth for anything out of the ordinary: gum swelling or bleeding, or dark spots on the teeth indicative of tooth decay. Look also for hard food particles like popcorn kernels caught between the teeth, which could be causing the pain. Gently floss between the teeth (even if you can't see anything) to remove any caught particles.
You'll also want to help ease their pain. You can apply an ice pack against the painful side of the jaw. Don't place ice directly on the skin, but use a container or cloth alternately against the jaw for a minute or so, and then away for a minute. You can also give them a dose of mild pain reliever like ibuprofen or acetaminophen appropriate for their age and weight—but never rub aspirin or other pain relievers on the gums, which tend to be acidic and can burn the skin.
Finally, you'll need to decide if you need to see a dentist and how soon. It might not be necessary with situations like the trapped food particles, but most of the time it's wise to have your dentist perform an examination for an accurate diagnosis and appropriate treatment. As to how soon, try to see the dentist immediately if the pain has continued from one day to the next or has kept your child up overnight. Otherwise, book an appointment for as soon as the dentist advises, even if the pain subsides.
A toothache at any age is never pleasant, but especially for children. Knowing these steps will help ease their discomfort and get them the relief and treatment they need.

Tooth decay and developing bite problems could be major obstacles to your child's normal growth and development. Without good, preventive dental care at home and from the dentist, these obstacles could impact their health now and well into adulthood.
Here are 3 things you should do to help your child stay ahead of harmful dental problems.
Start daily hygiene early. To protect your child from tooth decay, you should begin cleaning their teeth and gums early, even before teeth appear. For your first hygiene efforts use a clean wet cloth to wipe their gums after feeding to reduce bacterial growth in the mouth. After teeth begin to erupt start brushing them with a fluoride toothpaste—a slight smear for infants and up to a pea-sized amount when they get older.
Keep sugar to a minimum. The bacteria that causes tooth decay thrive on sugar. To minimize bacterial growth, keep your child's sugar intake to a minimum by providing dental-friendly snacks and foods. Also, try to limit any sugar they eat to mealtimes rather than with snacking through the day. And avoid sending them to bed with a bottle filled with a sugary liquid (including formula and breastmilk).
Begin dental visits around age one. Dentists and pediatricians recommend regular dental visits for children starting around their first birthday. This increases the chances of detecting disease or bite problems early before too much damage occurs. Your dentist can also provide preventive measures like sealants or topical fluoride to reduce the risks of tooth decay. And early visits lessen the chance of your child developing dental visit anxiety, a phobia that could continue into adulthood.
The longer many health problems go on, the worse they become. Treating them as early as possible could stop or slow their development.
That holds true for poor bites: while we can certainly correct them later in life, it's often better to "intercept" the problem during childhood. Interceptive orthodontics attempts to do this with treatments that influence how the jaws and other mouth structures develop during childhood. Many of these techniques are usually best implemented before puberty.
For example, some very complex problems called cross bites can occur if the upper jaw grows too narrowly. We might be able to stop this from happening by using an orthodontic appliance called a palatal expander during the childhood years. It works because the bone at the center of the palate (roof of the mouth) has a gap running back to front until the early teens when the gap closes.
We fit the palatal expander up under and against the palate, then extend out metal arms from a center mechanism to the back of the upper teeth that exert outward pressure on them. This widens the center gap, which the body continually fills with bone as the device gradually exerts more pressure. Over time this causes the jaw to widen and lessens the cross bite. Timing, though, is everything: it's most effective before the gap closes.
Another way to aid jaw growth is a Herbst appliance, a hinged device that alters the movement of the jaws. As a child wears it, a Herbst appliance draws the lower jaw forward to develop more in that direction. Like the palatal expander, it's best used before significant jaw growth occurs.
These are just two examples of techniques and tools that can guide structural growth and prevent bite problems. Because they're most effective in the early years of oral development, your child should undergo an orthodontic evaluation as early as age 6 to see if they need and can benefit from an interceptive treatment.
Interceptive orthodontics can stop or at least slow a growing bite problem. The effort and expense now could save you much more of both later on.
