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.

Although teething is a natural part of your baby's dental development, it can be quite uncomfortable for them—and upsetting to you. During teething, children can experience symptoms like pain, drooling or irritability.
Teething is the two or three-year process of intermittent episodes of the primary ("baby") teeth moving through the gums. These episodes are like storms that build up and then subside after a few days. Your aim as a parent is to help your baby get through the "stormiest" times with as little discomfort as possible. To that end you may have considered using over-the-counter products that temporarily numb irritated gums.
Some of those numbing products, however, contain a pain reliever called benzocaine. In recent years, this and similar ingredients have been found to increase the level of a protein called methemoglobin in the bloodstream. Too much methemoglobin can result in less oxygen delivered to body tissues, a condition known as methemoglobinemia.
This oxygen decrease can cause shortness of breath, fatigue or dizziness. In its severest form it could lead to seizures, coma or even death. Children and infants are at high risk for benzocaine-induced methemoglobinemia, which is why the U.S. Food and Drug Administration has banned marketing for benzocaine products as pain relievers for teething infants and children.
Fortunately, there are alternatives for helping your child weather teething episodes. A clean, chilled (not frozen) teething ring or pacifier, or a cold, wet washcloth can help numb gum pain. You can also massage their gums with a clean finger to help counteract the pressure exerted by an emerging tooth. Be sure, though, that you're not allowing anything in your child's mouth like lead-based paint that could be toxic. And under no circumstances should you use substances containing alcohol.
For severe pain, consult your physician about using a pain reliever like acetaminophen or ibuprofen, and the proper dosage for your child. With these tips you can help your child safely pass through a teething episode.
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.
