The words “overbite” and “overjet” certainly sound similar. Both conditions concern your front teeth. Both conditions fall under the same category of bite problems—Class II malocclusions, if you want to be technical. So it’s not surprising that they’re often used interchangeably. But while there are similarities, overbite and overjet are also distinctly different.

• Overbite/Overjet Geometry

In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.” With a Class II malocclusion, the upper front teeth project further beyond the lower teeth than they should.

Of course, teeth and bites are as individual as we are, so there are variations in just how and just how much the overlap occurs. In diagnosing an overbite vs. an overjet, the difference comes down to a matter of vertical vs. horizontal.

An overbite, or deep bite, occurs when the top teeth vertically overlap the bottom teeth more than they should for a healthy bite. Generally, when a person’s top teeth cover more than a quarter of the bottom teeth when biting down, or more than two to three millimeters, that person is said to have an overbite.

An overjet, commonly known as protruding or buck teeth, is the result of a horizontal overlap that is broader than normal. This causes the top teeth to project outward toward the lips more than they do in a typical bite. An overjet is usually diagnosed when the horizontal distance between the top and bottom teeth exceeds two to three millimeters.

• Overbite/Overjet Causes

The causes for both an overbite and an overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both. These bite problems can run in families. They are also affected by the size and position of the jaws and the shape and position of the teeth.

Early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to the development of a Class II malocclusion, particularly an overjet. Consistent pressure from thump or pacifier pushes the teeth outward as they erupt, which encourages them to protrude. These oral habits can affect the shape of the palate and jaw, too.

• Overbite/Overjet Treatments

There are many types of treatment available to correct teeth and bite misalignments. Dr. Iwei Huang will tailor your treatment to your specific malocclusion for the best orthodontic outcome.

If you have a mild malocclusion, and minor dental issues are the main cause of that malocclusion, either braces or clear aligners can be effective for an overjet or an overbite. Elastics (rubber bands) are often used as part of this treatment.

If the malocclusion is due to bite problems caused by uneven upper and lower jaw development, devices called functional appliances can be used with braces to help guide the growth of the jawbones while young patients’ bones are still forming. These include appliances that work inside the mouth to help the upper and lower jaws grow proportionally, and external appliances such as headgear.

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself. Orthodontic treatment is usually needed as well both before and after surgery.

• Overbite/Overjet Consequences

Over time, a deep overbite can cause damaged gum tissue, worn enamel, and fractured teeth. When teeth protrude because of an overjet, they can lead to self-consciousness and are more at risk for injury. Both malocclusions share dental and medical consequences, including concerns about facial and jaw appearance, problems speaking or chewing, headaches, and face and jaw pain.

Class II malocclusions aren’t all the same, and orthodontic patients aren’t all the same either. You may have a minor malocclusion or a significant one. You may have an overbite, or an overjet, or a combination of different bite and alignment concerns. Your malocclusion may not bother you at all, or it may cause pain, discomfort, or self-consciousness.

That’s why every overbite or overjet should be evaluated by an orthodontist. When you visit our Chicago orthodontic office, Dr. Iwei Huang will be able to diagnose the exact nature of your malocclusion, the reason for it, and your best individualized treatment plan. An overbite and an overjet are different malocclusions, but you and your orthodontist want the same outcome for each: a healthy, attractive, and confident smile!

While it’s normal to feel self-conscious, there is no reason to avoid photos just because you wear braces. Many people wear braces and you do not need to be embarrassed about them. There are also ways you can enjoy your photos without hiding your smile.

Make it Fun

Dr. Iwei Huang and our staff offer rubber bands for braces in a wide range of colors. Choose your favorite color and wear it with pride. You can mix and match your colors too. For Valentine’s Day, try alternating red and pink bands. For the Fourth of July, use red, white, and blue!

Bands are also available in neon colors and glow-in-the-dark designs. Your imagination is the only thing holding you back. You might want to avoid using dark green bands, though. It makes it look as though you have broccoli stuck in your teeth. Gross!

Make them Disappear

If your braces still really bother you in photos, technology can quickly solve the problem. A photo-editing program, or even a simple paint program, can easily erase your braces. Zoom in on your teeth, pick your natural tooth color with the dropper, and paint your braces away.

If you have a significant amount of metal in your braces, try to avoid close-ups with flash. The flash can reflect off the metal. The important thing to remember is how good your teeth will look and feel once your orthodontic work is complete. Dr. Iwei Huang and our staff can also show you options for braces that are not as visible as the traditional style.

Perhaps you feel your teeth are not perfectly straight, or you think your bite could be adjusted. It’s quite possible that braces and other orthodontic treatments might be the right choice for you. As orthodontic professionals, our team at Gold Coast Orthodontics works with your general dentist in order to determine the best options for your oral health and cosmetic appearance.

You might need braces if ...

• You lost your baby teeth relatively early in life. If your baby teeth fell out too early and your adult teeth did not come in for a while, this could have affected the way your adult teeth grew and developed.
• Your teeth look crowded or crooked. If you are embarrassed to smile because your teeth are not straight, it might be time to consider the cosmetic options available to you.
• Your jaw shifts or makes sounds. This can signify a developmental issue with your teeth and your jaw line, and orthodontic treatment may be able to help. Set up an appointment with Dr. Iwei Huang if your jaw is recessed or protruding as well.
• You are constantly biting the sides of your cheek or hitting the roof of your mouth. This could indicate that your teeth are not properly aligned. Braces can address an underbite or an overbite.
• You have a difficult time chewing your food. This is not only an inconvenience, but it can also be detrimental for your health. Braces can help fix the alignment of your teeth.
• You have to breathe through your mouth on a regular basis. You may not attribute this to an issue with the development of your teeth or jaw, but orthodontic treatment might be able to help.

The ideal age for a child to be seen by an orthodontist is age seven. However, there are many orthodontic treatment options available to adults. It is becoming increasingly common for adults to wear braces and other orthodontic devices. We recommend that people who are interested in braces and other orthodontic treatment options set up a consultation appointment with Dr. Iwei Huang today.

If Dr. Iwei Huang and our team at Gold Coast Orthodontics have recommended a palatal expander, you might be wondering what it is and how it will help you. A palatal expander is a small appliance fitted in your mouth to create a wider space in the upper jaw. It is often used when there is a problem with overcrowding of the teeth or when the upper and lower molars don’t fit together correctly. While it is most commonly used in children, some teens and adults may also need a palatal expander.

Reasons to get a palatal expander

There are several reasons you might need to get a palatal expander:

• Insufficient room for permanent teeth currently erupting
• Insufficient space for permanent teeth still developing which might need extraction in the future
• A back crossbite with a narrow upper arch
• A front crossbite with a narrow upper arch

How long will you need the palatal expander?

On average, patients have the palatal expander for four to seven months, although this is based on the individual and the amount of correction needed. Several months are needed to allow the bone to form and move to the desired width. It is not removable and must remain in the mouth for the entire time.

Does it prevent the necessity for braces?

The palatal expander doesn’t necessarily remove the need for braces in the future, but it can in some cases. Some people only need braces because of a crossbite or overcrowding of the teeth, which a palatal expander can help correct during childhood, when teeth are just beginning to erupt. However, others may eventually need braces if, once all their permanent teeth come in, they have grown in crookedly or with additional spaces between.
