Every year many parents learn their “tweenager” or teenager needs their bite corrected, often with specialized orthodontics. Imagine, though, if these families could go back in time to when their child’s poor bite was just developing to stop or slow it from forming.
Time travel may still be science fiction, but the approach suggested isn’t. It’s called interceptive orthodontics, a group of techniques and procedures performed during the early stages of jaw development. The focus is usually on getting abnormal jaw growth back on track, enough so that a poor bite won’t form.
The upper jaw, for example, may be growing too narrow, reducing the amount of available space for tooth eruption. If it isn’t corrected, teeth can erupt out of position. To correct it, an orthodontist places a palatal expander in the roof of the child’s mouth (palate). The appliance applies gentle pressure against the inside of the teeth, which stimulates the jaws to develop wider.
The expander works because of a separation in the bones at the center of the palate, which later fuse around puberty. The pressure applied from the expander keeps this gap slightly open; the body then continues to fill the widening expansion with bone, enough over time to widen the jaw. If you wait until puberty, the gap has already fused, and it would have to be reopened surgically to use this technique. Ideally, then, a palatal expander should be employed at a young age.
Not all interceptive techniques are this extensive—some, like a space maintainer, are quite simple. If a primary (baby) tooth is lost prematurely, teeth next to the empty space tend to drift into it and cause the intended permanent tooth to erupt out of place due to a lack of space. To prevent this an orthodontist places a small wire loop within the space to prevent other teeth from moving into it.
These are but two examples of the many methods for stopping or slowing a developing bite problem. To achieve the best outcome, they need to be well-timed. Be sure, then, to have your child undergo an orthodontic evaluation around age 6. If an interceptive orthodontic approach is needed, it could eliminate the need for more extensive—and expensive—treatment later.
When a woman learns she's pregnant, her first thought is often to do everything possible to protect the new life inside her. That may mean making lifestyle changes like avoiding alcohol or quitting smoking.
Some women may also become concerned that their regular dental visits could pose a risk to their baby. But both the American Congress of Obstetricians and Gynecologists and the American Dental Association say it's safe for pregnant women to undergo dental exams and cleanings—in fact, they're particularly important during pregnancy.
That's because pregnant women are more susceptible to dental infections, particularly periodontal (gum) disease, because of hormonal changes during pregnancy. The most common, occurring in about 40% of expectant mothers, is a form of gum disease known as pregnancy gingivitis. Women usually encounter this infection that leaves the gums tender, swollen and easy to bleed between the second and eighth month of pregnancy.
Untreated, pregnancy gingivitis could potentially advance below the gum line and infect the roots. It could also have an unhealthy effect on the baby: some studies show women with severe gum disease are more prone to give birth to premature or underweight babies than women with healthy gums.
But it can be stopped effectively, especially if it's treated early. Regular dental checkups and cleanings (at least every six months or more frequently if your dentist recommends) can help an expectant mother stay ahead of a developing gum infection.
With that said, though, your dentist's approach to your care may change somewhat during pregnancy. While there's little concern over essential procedures like gum disease treatment or root canal therapy, elective restorations that are cosmetic in nature might best be postponed until after the baby's birth.
So, if you've just found out you're pregnant, let your dentist know so they can adjust your care depending on your condition and history. And don't be concerned about keeping up your regular dental visits—it's a great thing to do for both you and your baby.

Just like adults, teenagers experience chipped, stained or disfigured teeth. And during a life stage where issues with appearance can be acutely painful, these defects call out for a solution.
And, there is one: porcelain veneers. These thin wafers of custom-made porcelain are bonded to the front of teeth to cover dental flaws. They’re one of the least invasive—and most affordable—methods for smile enhancement.
There is one caveat, though: The affected teeth will most likely need alteration. Veneers can look bulky when bonded directly to teeth, so we compensate for this by removing some of the surface enamel. This changes the tooth permanently, to the point that it will always require a veneer or some other form of restoration.
But although this may be a minor issue for an adult, it could pose a problem for a teenager. That’s because the pulp, the innermost layer of a tooth containing nerves and blood vessels, is larger in a younger adolescent tooth than in an older adult tooth. Because of its size, it’s closer to the tooth’s surface. During enamel reduction for veneers on a young tooth, this could lead to inadvertent nerve damage. If that happens, the tooth may need a root canal treatment to preserve it.
If the adolescent tooth needing a “facelift” has already been root canaled or sustained significant structural damage, then altering it for veneers may not be too concerning. Likewise, if the teeth are smaller than normal, the bulkiness of a veneer may actually improve appearance and not require alteration. We’ll need to examine a young patient first before making any recommendations.
There are also alternatives to veneers for improving smile appearance. Enamel staining could be enhanced temporarily with teeth whitening. Small chips can be repaired with bonded dental material, or in skilled hands be used to “build” a veneer one layer at a time with no enamel reduction. Although not as durable as regular veneers, these bonding techniques could buy time until the tooth is more mature for veneers.
Whichever path we take, there are effective ways to transform a teenager’s flawed tooth. And that can make for an even better smile.
