The term malocclusion refers to misalignment of teeth. You may have been born with malocclusion, so your teeth simply grew in crooked, or the misalignment and crowding of your teeth occurred over a period of time. Either way, not only can malocclusion pose cosmetic issues, but it can have a negative effect on your speaking and eating abilities as well.

Types of Malocclusion

Malocclusion encompasses multiple types and classifications of misalignment issues, including twisting or rotation of the teeth and molars that do not meet when you bite down. In some cases, the top front teeth are pushed outward in an upper protrusion.

In other cases, a misplaced midline results when the front top teeth don’t meet with the front bottom teeth. Transposition occurs when teeth protrude through the gums in a position where another tooth is supposed to be.

Practically any type of crowding or spacing issues, rotation or twisting of the teeth, or bite problem – including overbite, underbite, open bite, or crossbite – is included under the umbrella of malocclusion.

Malocclusion Classifications

There are three classifications of bite or misalignment problem.

• Class 1 malocclusion: While the bite may be normal, the upper teeth overlap the lower teeth slightly. This is the most common type.

• Class 2 malocclusion: Known as overbite or retrognathism, class 2 involves a severe overlap of the upper teeth and jaw over the bottom teeth and jaw.

• Class 3 malocclusion: Known as underbite or prognathism, class 3 occurs when the lower teeth and jaw overlap the upper teeth and jaw. Thus, the lower jaw juts forward.

Causes of Malocclusion

The most common cause of malocclusion is genetics. However, there may be other causes, including the development of abnormally-shaped teeth, lost teeth, or impacted teeth; thumb sucking or overuse of a pacifier as a small child; having fillings or crowns that do not fit correctly; a serious injury that causes misalignment of the jaw; or developing a tumor of the mouth or jaw.

Treating Malocclusion

Orthodontic care at Dr. Hummon & Dr. Gebeck Orthodontic Associates PC with Drs. Gregory Hummon and Thomas Gebeck is the main treatment available for malocclusion, which includes getting braces, Invisalign, or other corrective treatments. Treatment is ideal not just to have your smile improved, but because it makes the teeth easier to clean and maintain, lowers the risk of gum disease and tooth decay, and can even take pressure off the jaw and teeth.

Think about orthodontic treatment if you (or your child) display any signs of malocclusion. Early treatment of malocclusion during childhood can lessen expensive treatment later on.

At Dr. Hummon & Dr. Gebeck Orthodontic Associates PC, we proudly treat adults, teens, and children; no matter what your age, we believe you deserve a great smile.

Whether you’ve just come in for an initial orthodontic consultation with Drs. Gregory Hummon and Thomas Gebeck or your family has been visiting office for years, we would love to hear your thoughts about your treatment. In fact, we encourage you to leave a few words for us below or on our Facebook page!

Well, of course, they already are working for you—as an essential part of the alignment process. Rubber bands, also known as elastic ligatures, are used to secure the wires inside your brackets. But bands can be more than functional. Since the ligatures around each bracket are replaced when you visit our office, why not use that opportunity to choose a new color scheme as well?

• Make a Statement

Bands offer a chance to coordinate your braces to an interest, team, or event. Are you a swimmer? Maybe cool blues and turquoises appeal to you. Batman forever? Black and yellow. (That will work for beekeepers, too.) Have a favorite sports team? Choosing team colors will support your team with every smile. Love your school? Show your spirit by wearing bands in your school colors. Favorite time of year? Celebrate by selecting festive bands in holiday colors.

• Suit Your Mood

Fiery reds and oranges, tranquil blues and greens, millennial purples and pinks, or exuberant neon—you know that there are just some colors that suit your personality. Showcase that personality with your choice of band color. And if your mood changes, choose shades that express a completely different side of you.

• Coordinate Your Colors

Match your bands to your eye color, your makeup, or the clothing colors you choose most often. If there’s a color profile that works for you, make your bands a part of it. If you don’t want everything matching, complement your coloring or clothing with a different but coordinating shade for a cohesive effect.

• Keep a Low Profile

Most adults will stick with a monochromatic set of bands, and this might be a look that appeals to you as well. Grey and silver bands will blend nicely with silver braces. If you have clear or white brackets, you might want to test out which bands will be least noticeable. Clear bands can become discolored, and white bands can make teeth look darker. If there’s a band which mimics your own tooth color, this will be the choice for you.

• Make Color Theory Work for You

Certain colors and tints bring out the best in your tooth color and work with your skin tones. White and yellow bands might make teeth appear duller, and any shade combination that resembles food particles (greens, browns, and black) is probably not a look you’re going for. Have fun with a color wheel and decide which colors you find most flattering.

Make your bands more than a tool—make them an accessory. There are so many colorful options available that you are bound to happen on a color scheme that just suits you. And if you change your mind? Change it up during your next visit to our Birmingham office!

When does an underbite need surgery? The short answer is: when Drs. Gregory Hummon and Thomas Gebeck and our team recommend surgery as the best way to give you a healthy, functional bite. But let’s take a longer look, and see just why your doctors might come to that conclusion.

• First, what exactly is an underbite?

In a perfect bite, the upper and lower jaws align, well, perfectly. Upper teeth overlap lower teeth very slightly, upper and lower teeth meet comfortably, and jawbones and joints function smoothly. When the alignment is off, it causes a malocclusion, or “bad bite.”

When we talk about an underbite, or Class 3 malocclusion, it means that the lower jaw protrudes further than the upper jaw. This protrusion causes the bottom teeth and jaw to overlap the upper teeth and jaw.

• What causes an underbite?

Sometimes an underbite is caused by childhood behaviors while the teeth and jaw are developing, including tongue thrusting or prolonged thumb-sucking and pacifier use. (Working to stop these behaviors before they affect tooth and jaw formation is one of the many good reasons children should have regular visits with their dentists and pediatricians.)

Most underbites are genetic, however, and tend to run in families. It’s estimated that from five to ten percent of the population has some form of underbite. The lower jawbone (mandible) might be overdeveloped, the upper jawbone (maxilla) might be underdeveloped, both bones could be affected, or, sometimes, tooth size and placement might cause an underbite. These irregularities in jaw shape and size and/or tooth crowding are not something that can be prevented, and require professional treatment.

• Why? What’s the problem with an underbite?

Even a minor underbite can cause difficulties with biting and chewing. A more severe underbite can lead to speech problems, decay and loss of enamel where the teeth overlap, mouth breathing and sleep apnea, persistent jaw and temporomandibular joint pain, and self-confidence issues.

• Can’t my dentist treat my underbite?

Most probably not. A very mild underbite can be camouflaged cosmetically with veneers, but this does not address the cause of the underbite, and will not work for moderate or severe underbites.

• Can my orthodontist treat my underbite?

Drs. Gregory Hummon and Thomas Gebeck will create an underbite treatment plan after a detailed study of each patient’s individual dental and skeletal structure. Treatment options will vary depending on the cause of the underbite, its severity, and even the patient’s age.

Early intervention is especially important for children who show signs of an underbite. That’s why we recommend that children visit our Birmingham office by the age of seven.

If an underbite is caused by tooth misalignment or crowding, braces can reposition the lower teeth. Sometimes extractions are necessary to make room for proper alignment.

If the cause is due to jaw structure, children’s bones are still forming, so treatment can actually help correct bone development. Palatal expanders, headgear, and other appliances are various methods of encouraging and guiding bone development.

But braces and appliances aren’t effective for every patient with an underbite, and especially in patients (usually those in their late teens and older) when the jawbones are already fully formed. In this case, we might suggest coordinating treatment with an oral and maxillofacial surgeon.

• What does an oral and maxillofacial surgeon do?

An oral surgeon has the training, experience, and skill to help correct an underbite by surgically reshaping and repositioning the jawbone. This corrective jaw surgery is called orthognathic surgery.

• What will happen during orthognathic surgery?

Your treatment will be tailored to your specific needs. Two of the common surgical procedures for treating an underbite involve repositioning the upper jaw to lengthen it and/or reshaping the lower jaw to shorten it.

Bone is sometimes removed or added, small bone plates or screws are sometimes used to stabilize the bone after surgery—your surgeon will let you know exactly which procedures will give you a healthy, functional bite. The surgery itself is most often performed under general anesthesia and requires a brief stay in the hospital.

• How will my orthodontist and oral surgeon coordinate my treatment?

Correcting a Class 3 malocclusion can take time. Your oral surgeon will work together with Drs. Gregory Hummon and Thomas Gebeck to analyze the interrelationship of teeth, bones, and joints to determine dental and skeletal problems, and will develop the best treatment plan possible to create a healthy alignment.

• So, when does an underbite need surgery?

Sometimes, a minor underbite can be corrected with braces and appliances alone. A serious underbite, however, will often require the specialized skills of both Drs. Gregory Hummon and Thomas Gebeck and an oral surgeon.

And, while it’s not the primary purpose of surgery, corrective jaw surgery and orthodontics can also make you happier with your appearance and boost your self-confidence. Achieving a lifetime of beautiful, comfortable, and healthy smiles—that’s the answer to your question.
