Whenever we bite down, we’re applying force with our jaw muscles. Functional appliances direct these forces to create healthier tooth and jaw alignment. They’re used to help correct bite problems and to encourage symmetrical jaw growth.

Functional appliances aren’t always necessary. Because every child’s teeth and bite are different, orthodontic treatment at our Birmingham office is carefully tailored to your child’s individual needs.

• For the child with minor tooth misalignment, traditional braces or aligners might be all that’s needed.
• For the child with a minor malocclusion, or bite problem, an orthodontist might use elastics (rubber bands) to bring teeth into healthy alignment.
• For the child who has a more serious malocclusion, involving both tooth and jaw alignment, an orthodontist might recommend a functional appliance.

A severe Class II malocclusion can be caused when the upper jaw or teeth are positioned too far forward, and/or the lower jaw is too small or positioned too far back. Common Class II malocclusions include:

• Open bite—the front teeth don’t touch when the back teeth bite down, or the back teeth don’t touch when the front teeth close.
• Overbite—some overbite is normal. A deep overbite occurs when the upper teeth significantly overlap the lower teeth.
• Overjet—the upper front teeth protrude further horizontally than they should.

Today’s functional appliances come in a variety of designs to treat Class II malocclusions. They can be fixed or removable. They can be used with or without braces. Some are designed to expand the upper palate to make sure there’s room for all the permanent teeth. What they all do is advance the position of the lower teeth and jaw to create a healthier, more comfortable bite.

Fixed devices are attached to the teeth and meant to be used full-time. These include the Forsus™ device, the Herbst® appliance, and the MARA appliance.

• Forsus Device

This appliance works with braces. A spring coil rod is most often attached to bands on the first molars on the upper jaw. It’s then connected to the arch wire on the lower jaw. Just like elastics—but more effective!—these spring coil rods provide gentle forward pressure that encourages the lower jaw and teeth forward.  

• Herbst Appliance

The Herbst appliance also applies forward pressure to the lower jaw using telescoping rods connecting the upper and lower teeth. The rods expand as the mouth opens, and telescope together as it closes, positioning the lower jaw further forward while the upper jaw is held back. The Herbst can be worn alone or with braces, and can also be used to expand the upper palate.

• MARA Appliance

The MARA (Mandibular Anterior Repositioning Appliance) uses an adjustable “elbow” piece connecting bands on upper and lower molars to guide the lower jaw and teeth forward when the jaw closes.

Removable appliances such as Bionator and Twin Block appliances can also improve Class II malocclusions. They are meant to be worn for a specific number of hours each day, and can be taken out for sports or other activities as needed. Because it’s essential to get all the necessary hours in, removable appliances require commitment!

• Bionators

A bionator is made of wire and acrylic, and it looks a lot like a retainer. The wire fits around the upper front teeth. It’s attached to a smooth piece of acrylic that sits behind the upper teeth and is shaped to guide the lower jaw forward when biting down. The bionator can also be adjusted to expand the upper palate.

• Twin Block Appliance

The twin block appliance uses two separate pieces made of wire and smooth acrylic. Both pieces are modeled to fit precisely over the upper and lower arches. The acrylic “blocks” fit over the biting surfaces of the teeth, working together like a 3D puzzle. When your child bites down, the upper blocks slide into place behind the lower blocks, pushing the lower jaw and teeth forward. The top plate can also be adjusted to expand the upper palate if needed.

Because these appliances are best used while a child’s bones are still growing and developing, dentists and orthodontists recommend an orthodontic evaluation by age seven. Early treatment with a functional appliance can help correct serious bite problems before or together with braces. In some cases, functional appliances may reduce the need for headgear or surgery.

Todays’ orthodontic technology has made functional appliances more comfortable and efficient than ever before. Talk to Drs. Gregory Hummon and Thomas Gebeck to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

Wearing orthodontic braces may be the best choice for correcting your teeth and improving your smile, and that's why you've come to see Drs. Gregory Hummon and Thomas Gebeck at Dr. Hummon & Dr. Gebeck Orthodontic Associates PC. Braces, which consist of brackets and wires, work by gently applying pressure to the teeth, and that pressure causes them to move into the correct position. In some cases elastics, or rubber bands, are used to apply additional pressure needed to move your teeth.

The Purpose of Elastics

Customized for each patient, the rubber bands typically stretch over tiny loops on the top and bottom brackets. If worn consistently, and every day, these tiny elastics will apply the steady pressure needed to guide your teeth into the correct position.

These elastics are crafted from medical-grade latex, which is safe to be in contact with your mouth. It's common to remove the elastics during meals if opening your mouth wide enough to eat is difficult. Our staff will demonstrate how to affix the elastics so it will soon become second nature to replace them.

The Do’s and the Don'ts

DO - Get in the habit of carrying around extra rubber bands and replace them as soon as one breaks. By consistently wearing the elastics, you may shorten the overall time needed to wear braces.

DON'T - Double up on elastics as this will cause too much pressure on the tooth or teeth and can actually harm the root of the tooth.

DO - Always wash your hands before removing or replacing the rubber bands.

DON'T - Overstretch the rubber band or it will lose its strength and it will be ineffective.

DO - Call us if you run out of rubber bands.

DO - Have fun with your braces and elastics. There are many different colors available that can let you show off your soon-to-be perfect smile.

Rubber bands are a key part of your orthodontic treatment, and learning how to remove and replace them is an important part to maintaining your braces. Before we set you on your journey to a perfect smile, we'll make sure you understand all there is to know about how to take care of your braces. Of course, if you have any questions about your orthodontic treatment, or orthodontics in general, be sure to contact our Birmingham office, and our staff will be happy to assist you!

You have a lot going on. School. Sports. Activities. Family. Friends. Teens lead busy lives and have busy schedules, so you need to budget your time and energy. One thing you don’t want to spend any of your time and energy on? Dealing with gum disease.

Gum disease most often begins as a reaction to plaque and tartar. The bacteria in plaque produce acids which irritate gum tissue, causing inflammation, swelling, and bleeding. This is gingivitis, the early stage of gum disease.

Left untreated, early gum disease can become periodontitis. Periodontitis is a serious gum infection which can cause receding gums, loose teeth, and even tooth and bone loss.

We usually think about gum disease as something that only older adults worry about. But the unfortunate fact is that children and teens are also at risk for gum disease—and the teen years bring special risks. Why?

• Braces

The teen years are the most common years for orthodontic treatment. Wearing traditional or lingual braces can make removing plaque from around brackets and wires, between the teeth, and near the gum line more challenging, and gum disease can be the result. When you’ve been working so hard to create a healthy attractive smile, you don’t want to delay your orthodontic progress to treat gum disease.

• Less-than-Nutritious Snacking

When you have after school commitments like sports practices, play rehearsals, or work, you probably carry a snack to give you the energy you need until dinner. Popular snacks like energy drinks, chips, or candy bars are common go-to choices, but they contain acids, simple carbs, and sugars which are bad for both gums and tooth enamel.

• Hormones

Increased hormone levels during puberty can make the gums more sensitive and more easily irritated.

• Your Busy Life

Maybe you’re not getting enough sleep. Or eating as well as you could. Or you’re feeling anxious. Lack of sleep, poor nutrition, and stress can affect your body’s immune system and your ability to fight off infection. And if you’re also not brushing and flossing regularly, your gum health can really suffer.

How do you know if you have gum disease? Good question! Sometimes the early stages of gum disease aren’t obvious. Perhaps you’ve noticed changes in your gums, such as:

• Redness
• Swelling
• Soreness
• Bleeding
• Bad breath even after brushing

Any of these changes can be symptoms of gum disease and are a good reason to give our Birmingham office a call, since time is important when treating gum disease.

Caught early, gingivitis is usually very treatable—in fact, you can often reverse early gingivitis by paying more attention to your daily dental hygiene. If gingivitis is more advanced, or if periodontitis develops, you need professional dental care to prevent serious damage to your gums, teeth, and bone.

Preventing gum disease from ever developing is always best, though, so let’s look at what you can do to keep gum disease from becoming a problem.

• Keep Up with Healthy Dental Habits

Even though you’re leading a busy life, take time for your dental care. Brushing twice a day for at least two minutes per session and flossing once a day take just a bit of your time and are the best way to keep your gums healthy. If you wear braces or have a tendency toward cavities and gum disease, Drs. Gregory Hummon and Thomas Gebeck might recommend brushing or flossing more often.

• Use the Right Tools

Using the right tools makes a big difference. You should always choose a toothbrush with soft bristles to protect your delicate gum tissue—especially if it’s extra sensitive. Too-harsh brushing can damage even your super-hard tooth enamel, so you can imagine what it can do to your gums! Change out your brush every three to four months when it starts to get frayed and worn.

If you wear braces, ask Drs. Gregory Hummon and Thomas Gebeck to recommend the best kind of floss to clean between your teeth and around your brackets and wires. The right tools will make flossing a lot easier, and will help you keep your gums healthy and your orthodontic treatment on track.

• No Matter How Busy You Are, Treat Yourself Well

Watch your diet. Drinking water to hydrate is a healthy (and inexpensive) alternative to sugary and acidic drinks. When you know you have after-school commitments, pack yourself a healthy snack. After snacking, it’s a good idea to rinse with water when you can’t brush to remove any food particles sticking around your teeth and gums.

And even though your schedule is demanding, caring for your mind and body should be a priority. If you have difficulties with sleep or stress, or questions about a nutritious diet, talk to your doctor for some valuable tips to make your daily life healthier and more enjoyable.

With so much going on in your active life, gum problems are problems you really don’t need. Make room in your schedule now for careful daily brushing and flossing, a healthy lifestyle, and regular visits to Dr. Hummon & Dr. Gebeck Orthodontic Associates PC, and you’ll be living that active life with a beautiful, healthy smile!

Temporomandibular joint disorders (TMD) describe a set of conditions that involve trouble with your jaw and face muscles. They result from a problem in the temporomandibular joint (TMJ), which is a hinge that connects the temporal bones, in your skull in front of each ear, to your jaw. The joint enables you to talk, yawn, and chew by letting your mouth move.

TMD can be very painful and interfere with functions such as eating and speaking. This what to watch for and how to try to prevent TMD.

Risk Factors for TMD

You are at higher risk for TMD if you are a women than if you are male. The disorder is most common among adults between the ages of 20 and 40 years. Other risk factors for TMJ disorders include the following.

• Arthritis in the area, making movement more difficult
• Excessive tooth grinding, because it increases stress on the joint
• General stress, which can lead you to clench your teeth and strain facial muscles

Symptoms of TMD

Symptoms of TMD can last for just a short while, or for several years. Seeing Drs. Gregory Hummon and Thomas Gebeck is important if your symptoms make it impossible for you to eat regularly or if you have unbearable pain or discomfort. The following symptoms can occur on both or one side of your face.

• Aching or very tired facial muscles
• Jaws that are fixed open or shut without you being able to unlock them
• Grating or popping sounds when you chew or close or open your mouth
• Pain in the entire area, including the mouth, jaw, neck, or shoulders, that comes on when you chew or yawn

Preventing TMD

You can try to prevent TMD by focusing on reducing risk factors. If you grind your teeth at night, ask Drs. Gregory Hummon and Thomas Gebeck about wearing a mouthguard. If you are overly stressed, look into ways to better manage your stress and relax your muscles. Another strategy for trying to prevent the development of TMD is to avoid chewing gum, since that puts stress on your jaw.

If you have questions about TMD, don’t hesitate to contact our Birmingham office.
