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. Randall Welser and Dr. Lora Marine. 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 Moline or Geneseo, IL or Clinton, IA 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. Randall Welser and Dr. Lora Marine 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.

You’ve been told that you have a malocclusion called an “underbite.” Let’s look at just what this diagnosis means, and what it means for you.

Just what is an “underbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a typical bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth.

An underbite, on the other hand, results when the lower teeth and jaw extend further forward than the upper teeth and jaw, causing the bottom teeth to overlap the top teeth.

What causes an underbite?

Underbites tend to be genetic, and run in families, so, most often, an underbite is something you’re born with. The size of your jaws, the shape of your teeth, or both will affect your bite.

A smaller number of underbites develop because of injuries or early oral habits, such as prolonged and vigorous thumb sucking or tongue thrusting.

How do we treat an underbite?

Your treatment will depend on the type and severity of your underbite, and your age when treatment occurs.

• Braces and Aligners

If your underbite is a slight one, caused, for example, by crowded or overly large teeth, braces or clear aligners can help move the teeth into proper alignment.

• Functional Appliances

If the underbite is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still growing and forming.

If you’re a young patient, two appliances commonly used to help correct an underbite are palatal expanders, which gradually widen the upper jaw if it’s too narrow, and reverse pull headgear, which fits both inside the mouth and outside on the face, and provides a steady, gentle pull to encourage the forward growth of the upper jaw.

• Surgical treatment

In some severe cases, surgical treatment can correct an underbite by reshaping the jawbone itself and positioning it further back to align properly with the upper jaw.

Why treat your underbite?

A serious underbite can cause damaged teeth and enamel, painful problems with the temporomandibular joint, headaches and facial pain, sleep apnea, difficulty chewing, eating, and speaking, and can affect confidence and self-esteem.

By following your treatment plan, you’ll not only prevent these consequences, but you’ll achieve major benefits—a healthy, comfortable bite, and an attractive, confident smile. Want to know more?

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. Randall Welser and Dr. Lora Marine 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 Moline or Geneseo, IL or Clinton, IA 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.

Dry mouth, also medically known as xerostomia, is the condition of not having enough saliva, or spit, to keep your mouth wet. There are many ways to keep dry mouth at bay, including:

• Brushing your teeth after every meal with a fluoride toothpaste
• Flossing every day after a meal
• Avoiding tobacco, as well as drinks containing alcohol or caffeine
• Avoiding dry foods, as well as foods containing high salt, acid, spice, or sugar levels
• Drinking water frequently or sucking on ice chips
• Using a humidifier at night
