Maybe you’ve known people with braces and aligners—maybe you’ve worn them yourself!—so if braces or aligners are in your teen’s future, you have some idea what to expect and when to expect it.

But quite often, orthodontic issues require more treatment than braces alone can provide. When misalignment affects not only the teeth but the jaw as well, treatment can be more effective when it begins earlier and makes use of a different kind of appliance—the “functional appliance.”

During the years your child’s bones are still rapidly growing and forming, around the ages of eight to 14, functional appliances can help guide tooth movement and encourage jaw growth and development. One of the most widely used of these devices is the Herbst® appliance.

What does the Herbst appliance do?

There are several types of malocclusions, or “bad bites” treated by Dr. Iwei Huang. A common condition called a Class II malocclusion occurs when the upper jaw and teeth project too far forward over the lower jaw and teeth. Signs of a Class II malocclusion might include an overjet (protruding upper teeth), and/or a small or recessive lower jaw.

While correcting this malocclusion often enhances facial symmetry, which can be very important for a child’s confidence, correcting a Class II malocclusion also promotes jaw and dental health. Misaligned teeth are more difficult to clean, which can lead to decay and gum disease. Bite problems can cause persistent jaw pain and damage to the teeth. And, with an overjet, a child’s upper teeth are more at risk for injury.

The Herbst appliance was developed to treat this kind of malocclusion. It moves the lower jaw and teeth forward to create a balanced, healthy smile.

How does the Herbst appliance work?

The Herbst appliance is fixed in place with stainless steel bands or crowns that are secured to four teeth in the rear of the mouth, often the first molars on each side of the upper and lower jaws. The band or crown on each lower tooth is equipped with a small bar that extends toward the front of the mouth.

An arm on each side links the bands or crowns on the upper teeth to the front of the bar assemblies on the lower teeth. Each arm consists of a rod that fits smoothly into a tube. The telescoping action of the rod and tube allows the mouth to open and close normally. When the mouth is closed, the arms on both sides telescope shut, forming compact cylinders that hold the jaw forward.

While a child’s bones are still growing, the lower jaw’s new forward position can stimulate further bone growth and remodeling to maintain the jaw in that forward position. The Herbst appliance also has a restraining effect on the forward movement of the upper jaw. The result is a steady, noticeable improvement in the relationship between the upper teeth and jaw and the lower teeth and jaw.

Is the Herbst appliance hard to take care of?

The Herbst appliance is fairly low maintenance, but, like any orthodontic gear, it should be treated with care.

• It’s important to watch your child’s diet, because sticky, crunchy, and chewy foods can damage the appliance. Save the caramels for a post-treatment celebration!
• Carefully cleaning around the appliance is necessary, because a buildup of bacteria and plaque leads to consequences like bad breath, gum disease, and tooth decay. A water flosser can make reaching and cleaning tight spots easier if a brush alone isn’t effective.
• If the Herbst appliance is damaged, some minor fixes might be doable at home with instructions from your treatment team. But if a band or crown comes loose, or if there’s a problem you’re unfamiliar with, call our Chicago office right away.
• To help avoid the need for minor (or major) fixes, playing with the appliance with fingers or tongue, nibbling on pens and pencils, chewing on ice, or any other risky habits should be strictly off limits.

When it comes to your child’s health, you always have high expectations. Dr. Iwei Huang and our team have all the answers you’ll need about what to expect from this phase of your child’s orthodontic treatment, and just why the Herbst appliance is the very best option to create a future of attractive, healthy smiles.

Most of our patients at Gold Coast Orthodontics will need to wear rubber bands at some point during their orthodontic treatment. The main reason our patients are instructed to wear rubber bands is to correct their bite. If your teeth do not fit together properly, Dr. Iwei Huang will recommend that rubber bands be used. Dr. Iwei Huang may also recommend using rubber bands to close or open spaces.

Rubber bands are a critical part of your treatment, and wearing them as Dr. Iwei Huang and our team recommend will help move your teeth into the desired position. Dr. Iwei Huang may ask you to wear your rubber bands full time, meaning that they should only be taken out when you brush and floss your teeth three times a day. Other times, you may be asked to only wear them part-time, like only during the day or only during sleep.

If you still have any questions about orthodontic rubber bands, we invite you to give us a call or ask us during your next adjustment appointment. Remember, wearing rubber bands as prescribed by Dr. Iwei Huang is an important step during your treatment, and can reduce the time you have your braces. If you lose your rubber bands or run out, stop by our Chicago office and pick up more!

Sometimes real life is stranger and more interesting that any made-up story. These weird and interesting facts about braces will amuse you … and make you glad you didn’t have to get braces “way back when.”

Mummies with braces: Archaeologists have discovered mummies with crude bands of metal wrapped around their teeth. The metal was wrapped around each individual tooth, and it is believed that ancient dentists used catgut to guide the teeth and close the gaps.

First “official” braces: The first official braces were constructed in 1728 by Pierre Fauchard. They consisted of flat strips of metal. String was used to connect the metal to the teeth.

Early rubber bands: In 1850, Tucker began making rubber bands out of rubber tubing.

Brackets are better: Brackets were invented by Edward Angle in 1915. They were not bonded to the teeth directly, but instead were attached to bands that went around the teeth.

Wiring by NASA: As braces have become more modern, the technology has improved by leaps and bounds. You may know that some braces wire contains nickel titanium. What you may not know is that this metal was developed by NASA and has special shape memory that is activated by pressure or body heat.

Over 60 with braces: Actress Faye Dunaway got braces at the age of 61, which shows you are never too old to look more fabulous!

Oh, and one more thing that didn’t quite make our list, but is interesting all the same. Did you know that almost 25 percent of patients who get braces have to get them again because they wouldn’t wear their retainers? So suck it up, buttercup, and use that retainer!

If you’re heading back to classes in the next few weeks, you’re probably getting your gear together now. So let’s talk about some of the items you can pack to make orthodontic care easier during school hours.

• Dental-Healthy Food

Watching what foods you eat is especially important now. If you’re carrying your lunch or snacks in your pack, you want to be sure that they’re approved for braces and aligners.

If you wear braces, avoid foods which are sticky, chewy, or crunchy. They can stick to your teeth (making it easier for cavities to develop) or cause damage to your brackets and wires (making repairs necessary). Your orthodontist will give you a list of braces-friendly foods.

If you have clear aligners, even though you’ll remove them to eat, that sticky rule still applies. You don’t want food trapped in your aligners if you can’t brush right after eating, because that food is also food for the oral bacteria which cause cavities.

Bringing a water bottle with you is a great idea if it’s hard to brush after eating. Rinsing with water is a good way to get rid of loose food particles, and staying hydrated helps maintain normal saliva production—which also helps wash away food debris.

• Toothbrush, Toothpaste, and Floss

It’s best to clean your teeth after every snack and meal if at all possible. A travel-sized brush, toothpaste, and dental floss or picks designed for braces will help you get rid of any unwanted dental leftovers. And a small mirror can help you discover any lingering food particles.

It’s especially important now to practice careful hygiene, so be sure to wash your hands before and after cleaning your teeth or appliances.

• Your Aligner or Retainer Case

Whenever you take off your retainer or aligners to eat, you should always have your case handy. Cases make sure your appliances stay off germy desk and table surfaces—or worse, floors—and protect them from breakage. A case is also a good way to make sure your retainer doesn’t accidentally end up in a trash bin after lunch.

Again, before and after you handle your braces, aligners, or retainer, be sure to wash your hands carefully.

• Dental Wax & Extra Bands

Sometimes a wire comes loose or a bracket irritates the inside of your cheeks or mouth. In this case, dental wax is a great way to protect yourself from irritation and injury. And if a band is lost or breaks, it’s always good to have a spare (or two) handy. As always, handwashing rules apply!

• Your Mouth Guard

If your afterschool activities involve contact sports, a mouthguard is always a good idea, and especially when you wear braces. Dr. Iwei Huang can create a custom guard which will protect your teeth, your delicate mouth tissue, and your braces from many impact injuries.

• Your Orthodontist’s Phone Number

One important item that takes up almost no space in your backpack, locker, or phone is the phone number for our Chicago office. If your braces are damaged, or if your aligner or retainer is lost or broken, we will let you know what to do until you can safely visit the office in person.
