“Orthodontic treatment” and “braces” almost seem like synonymous terms. But while braces certainly are orthodontic, it isn't the only tool in an orthodontist's toolkit.
A good example is a device is known as a Herbst appliance. It's used in situations where the upper jaw is outpacing the growth and development of the lower jaw during childhood. If not corrected, this could cause the top teeth to protrude abnormally beyond the lower teeth.
The Herbst appliance gently and gradually coaxes the lower jaw to grow in a more forward direction, thus “catching up” with the upper jaw. The top part of the device consists of two metal tubes hinged to small elastic bands, which are cemented to the cheek side of the upper back teeth (molars), one on either side of the jaw.
Two smaller tubes are attached in like fashion to the lower teeth, and then inserted into the larger tubes. As the lower jaw moves, the smaller tubes move within the larger to create pressure that gently pushes the jaw forward. Over time, this can sync the growth progress of both the upper and lower jaws, and reduce the chances of a poor bite.
For best results, a Herbst appliance is usually placed to coincide with a child's most rapid period of jaw growth, usually between 11 and 14. They could be placed as early as 8 or 9, however, in situations where the front teeth are already protruding well beyond the lips. In any event, the goal is to positively influence the growth of the lower jaw to alleviate or at least minimize the need for future orthodontic treatment.
As a fixed device, there's no need for a child or parent to tend to it as with other methods, like orthodontic headwear worn in conjunction with braces. A Herbst appliance can, however, alter the normal sensations associated with eating, swallowing and speaking, which may take a little adjustment time for the child. Wearers will also need to be extra vigilant with daily brushing and flossing because of a higher risk of tooth decay.
These, though, are minor inconveniences compared with the benefit of improved bite development. As such, a Herbst appliance could be a positive investment in your child's dental future.

From a dentist's perspective, toothbrushes have a limited lifespan: Bristles can fray after months of use, rendering them less effective in removing harmful dental plaque. The American Dental Association therefore recommends a new brush at least every three to four months.
From a user's perspective, that's not that big a deal—toothbrushes are relatively inexpensive and plentiful in stores selling oral hygiene products. In fact, many dentists give their patients a new toothbrush after each dental cleaning.
But there's still another perspective: Mother Earth. Too many of those used toothbrushes end up in the trash. With potentially billions of disposed toothbrushes each year, this essential dental care tool could well be a significant contribution to our planet's overflowing waste problem.
Fortunately, you don't have to consign your used toothbrush to the landfill. After a sanitizing run through the dishwasher, there are dozens of ways to re-purpose your old brush. In recognition of Earth Day, April 22, here are a few of them.
Kitchen cleanup tool. Your kitchen is likely filled with various utensils and small appliances like toasters or blenders that contain lots of nooks and crannies. These spaces can quickly fill up with spills or food debris. With their narrow heads and long handles, old toothbrushes are ideal for tidying up your hard-to-clean kitchen equipment.
Tile grout cleaner. Those narrow bristles also make toothbrushes a great tool for cleaning bathroom tile grout. Simply apply your favorite cleaner, or a little baking soda added to water, and let your old toothbrush do the rest. A toothbrush is also handy for cleaning around other tight spaces around the sink, tub or toilet.
Personal hygiene aid. After retiring from teeth cleaning, your brush can still play a role in personal hygiene. Use if for cleaning under fingernails, removing hair from hair brushes or even getting your eyebrows in good order. They're also handy for applying hair dye if you can't lay your hands on the regular application brush.
Miscellaneous task helper. A used toothbrush can be useful for tasks in and out of the house. Inside, it can help you remove your child's crayon art from walls or tackle stubborn clothes stains. Outside, it's handy for cleaning different parts of your car, the soles of your shoes or grimy bicycle chains. When you need something small and narrow, a toothbrush might just fill the bill.
Have more than enough used toothbrushes? Then consider recycling the next one, if your local program allows it. In its separated components your toothbrush can thus continue to be useful—and not another piece of clutter on our beautiful planet.
Inauguration night is usually a lavish, Washington, D.C., affair with hundreds attending inaugural balls throughout the city. And when you're an A-List celebrity whose husband is a headliner at one of the events, it's sure to be a memorable night. As it was for super model Chrissy Teigen—but for a slightly different reason. During the festivities in January, Teigen lost a tooth.
Actually, it was a crown, but once she told a Twitter follower that she loved it “like he was a real tooth.” The incident happened while she was snacking on a Fruit Roll-Up (those sticky devils!), and for a while there, husband and performer John Legend had to yield center stage to the forlorn cap.
But here's something to consider: If not for the roll-up (and Teigen's tweets on the accident) all of us except Teigen, her dentist and her inner circle, would never have known she had a capped tooth. That's because today's porcelain crowns are altogether life-like. You don't have to sacrifice appearance to protect a tooth, especially one that's visible when you smile (in the “Smile Zone”).
It wasn't always like that. Although there have been tooth-colored materials for decades, they weren't as durable as the crown of choice for most of the 20th Century, one made of metal. But while gold or silver crowns held up well against the daily grind of biting forces, their metallic appearance was anything but tooth-like.
Later, dentists developed a hybrid of sorts—a metal crown fused within a tooth-colored porcelain shell. These PFM (porcelain-fused-to-metal) crowns offered both strength and a life-like appearance. They were so effective on both counts that PFMs were the most widely used crowns by dentists until the early 2000s.
But PFMs today make up only 40% of currently placed crowns, down from a high of 83% in 2005. What dethroned them? The all-ceramic porcelain crown—but composed of different materials from years past. Today's all-ceramic crowns are made of more durable materials like lithium disilicate or zirconium oxide (the strongest known porcelain) that make them nearly as strong as metal or PFM crowns.
What's more, coupled with advanced techniques to produce them, all-ceramic crowns are incredibly life-like. You may still need a traditional crown on a back tooth where biting forces are much higher and visibility isn't an issue. But for a tooth in the “Smile Zone”, an all-ceramic crown is more than suitable.
If you need a new crown (hopefully not by way of a sticky snack) or you want to upgrade your existing dental work, see us for a complete exam. A modern all-ceramic crown can protect your tooth and enhance your smile.
