The Herbst® Appliance

April 27th, 2022

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. Joseph Brogan. 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 Philadelphia, PA 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. Joseph Brogan 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.

Straight Talk about Braces and Oral Health

April 20th, 2022

We’ll give it to you straight: it can be harder to keep your teeth their cleanest while you’re wearing braces. Food particles play hide-and-seek, plaque builds up around brackets, flossing is harder when you need to maneuver around wires. But keeping your teeth and gums healthy is even more important now that you’re wearing braces.

Why? Because when your braces come off, you want to enjoy the beautiful smile you’ve worked so hard for without worrying about discolored enamel, cavities, or swollen gums. Let’s look at some of the possible consequences when brushing and flossing are more challenging.

Decalcification

If you’ve noticed white spots around your brackets, you’re seeing the signs of decalcification, a common problem for those who wear braces.

Decalcification begins when plaque collects on the enamel around your brackets. The bacteria in plaque produce acids. These acids eat away at the minerals which keep your enamel strong, minerals like calcium and phosphorous. Places on the enamel where erosion takes place are left weakened and discolored.  Eventually, these weak spots can lead to . . .

Cavities

When plaque sticks around, whether near your brackets or anywhere on your teeth, it provides the perfect conditions for decay to develop. Left untreated, bacterial acids continue working away at decalcified spots in your enamel. This continuing erosion causes these surface spots to expand, grow deeper, and become cavities.

If you’re having trouble with built up plaque, and brushing isn’t doing the job for you, your dentist can remove it with a professional cleaning. Getting rid of plaque is healthy not only for your enamel, but your gums as well.

Gum disease

When plaque and tartar collect around the gumline, they irritate delicate gum tissue. This irritation causes gingivitis, or early gum disease. And, while young people rarely suffer from serious gum disease, the pain, redness, bleeding, swelling, and bad breath caused by gingivitis are not anyone’s life goals!

Brushing and flossing are essential to keeping your enamel and gums plaque-free. But even if you brush more often, it’s not as easy as it once was now that you have to work around and between brackets and wires. Luckily, there are lots of tools out there to help you get your teeth, gums, and braces their cleanest.

  • Orthodontic toothbrushes

Special brushes designed just for braces can help you work around brackets and wires. V- or U-shaped bristle formations let you brush around and over your braces. Curved bristles can fit under wires. Smaller brush heads let you reach those hard-to-reach places.

  • Electric toothbrushes

Many people find these brushes can clean more easily and effectively, especially when wearing braces. Tapered orthodontic brush heads are available, and, if you’re a heavy-handed brusher, there are models which alert you if you’re brushing too hard—protecting your braces and your enamel.

  • Orthodontic floss

Special orthodontic flosses can help you do the tricky job of fitting floss behind your wires and between your teeth, or use a floss threader, which helps guide uncooperative floss into tight spaces.

  • Water flossers

With their pulsing streams of water, water flossers can reach spots where regular brushes and flosses just can’t comfortably fit. There are even flossers available with special orthodontic tips.

Straight teeth are great. Straight and healthy teeth? Even better! You, Dr. Joseph Brogan, and our Philadelphia, PA orthodontic staff make a great team. Take advantage of our advice and tips for the best tools and techniques to make sure your smile is both perfectly aligned and perfectly healthy once those braces come off!

Why Do I Need a Retainer?

April 13th, 2022

Congratulations! You’ve done the hard work necessary to create your beautiful smile! You’ve carefully completed all the steps needed to reach the end of your orthodontic journey. Well, nearly all the steps. We can’t forget that last step which will ensure that all your hard work is rewarded.

When you first began orthodontic treatment, Dr. Joseph Brogan decided on the best plan for straightening your teeth and perfecting your bite, whether you wore traditional braces, lingual braces, aligners, or other orthodontic appliances. And now that you’re finishing treatment, there’s one more option to consider—your retainer.

Why do I need a retainer?

While you’ve spent time in treatment, more has changed than just the position of your teeth. The periodontal ligament, the connective tissue that connects the teeth to the jawbone, is stretched as the teeth shift. The bone in your jaw changes, too, reforming and rebuilding around the roots of your teeth as they move to their ideal locations.

These changes happen because your braces or aligners apply gentle, constant pressure to move your teeth. When you’ve finished wearing these appliances, the pressure stops. Ligaments will try to return to their original shape, which can shift teeth back toward their old positions. And the rebuilding bone isn’t dense enough yet to stop teeth from shifting due to the normal, everyday pressures of eating, chewing, and smiling.

A retainer prevents your teeth from moving back, or “relapsing,” by giving your bones and ligaments time to stabilize and rebuild. The process takes months, so keeping your teeth in place as bones rebuild and grow denser is crucial. This is especially important for patients with more serious misalignments. Dr. Joseph Brogan will let you know which kind of retainer will be best for you and just how long you’ll need to wear your retainer.

Are there different kinds of retainers?

There are! Retainers can be removable or fixed, visible or nearly invisible, metal, plastic, or metal and plastic. Three of the most popular retainer options include:

  • Hawley Retainers—the traditional removable retainer, which uses a molded acrylic plate with wires attached to keep your teeth properly aligned and to hold your retainer in place.
  • Clear Plastic Retainers—a removable retainer made of custom vacuum-formed plastic, which fits over the teeth like a clear aligner.
  • Fixed Retainers—a small single wire bonded to the back of specific teeth, which holds them in place and prevents any movement.

Dr. Joseph Brogan will let you know whether a removable or fixed retainer is best for making sure your teeth don’t start to relapse, and fill you in on the benefits and care of each type of retainer.

How long do I need to wear a retainer?

There’s no standard answer to this question. Just like your retainer is custom-built to fit your individual teeth, the amount of time you’ll spend in that retainer depends on your individual needs. Retainers might be worn fulltime for months or years, be worn only at night after several months of daily wear, or be worn long-term to make sure your orthodontic work lasts.

Because you’ve done the hard work already, and your beautiful, healthy smile is the result. Talk to a member of our Philadelphia, PA team about which retainer option will be best for making sure that this smile lasts a lifetime.

Bells and Whistles for Your Bristles?

April 6th, 2022

Modern dentistry has made the most of today’s technological innovations. And we’ve come a long way from the fraying sticks our ancestors used as toothbrushes.

On the other hand, while it’s a lot better than a fraying stick, the manual toothbrush model you’ve used for years might be ready for an upgrade. Should you take this opportunity to try out some new technology offering all the bells and whistles? Let’s answer that question by asking a few more questions.

Happy with your manual brush?

If you like your manual toothbrush and it’s doing the job, by all means, stick with it. But even your old familiar brush can evolve:

  • There are lots of bristle options, but soft bristles are almost always the way to go. Medium and hard bristles can be too abrasive for your enamel.
  • Heads come in a variety of sizes, so make sure the head size is comfortable. You want to be able to maneuver to reach every tooth surface, which a too-large brush head just can’t do.
  • Try a different handle shape if you’re having trouble maneuvering and keeping a firm grip.
  • Change your brush regularly. Brushes are effective for about three months before the bristles start to fray and breakdown. This is a good opportunity to experiment with different brands and styles.

Does your old brush suit your current needs?

Different types of manual toothbrushes are available for effective and comfortable brushing when you need options that a typical brush doesn’t provide:

  • Special orthodontic toothbrushes are designed with bristles trimmed to fit around brackets and wires and smaller heads to reach into tight places.
  • For those with mobility issues, brushes with larger or easy-grip handles make cleaning more comfortable.
  • Brushes with extra-soft bristles are available if you have enamel erosion or sensitive gums.
  • Because many women find their gums become especially sensitive during pregnancy, there are brushes designed especially for moms-to-be.

Is it time to go electric?

If you haven’t tried an electric toothbrush before, you might find that getting braces is a great reason to give one a spin.

  • Electric toothbrushes can outperform manual models. A dedicated brusher might manage hundreds of brushstrokes for each minute of brushing, while an electric brush can provide thousands. If, despite your regular brushing, you have plaque build-up, an electric brush might be a good alternative to your manual brush.
  • Models are available which can alert you when you’re brushing too hard—which is important for your enamel if you’re a heavy-handed brusher.
  • If you tend to *think* you’ve brushed for the recommended two minutes, but have *actually* brushed 32 seconds, some electric brushes come with timers!
  • There are tapered electric orthodontic brush heads designed just for people with braces.
  • Electric brushes have bigger handles and can be easier to grip.

Is your current brush doing the job?

So, should you stick with the familiar toothbrush that’s worked for you all these years, or take this opportunity to try out some new technology that offers all the bells and whistles? The answer is clear: the right brush for you is the one that works!

If your regular checkups show that plaque is under control, you’re doing just fine with the brush in hand. If you or Dr. Joseph Brogan notice plaque buildup, it’s time to consider making some changes. Whether it’s a question of tools, techniques, or time spent brushing, your Philadelphia, PA dental team has the answers you need for state-of-the-art dental hygiene.
