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. Quas, Dr. Wiater and Dr. Kang 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 Bend, Redmond, Prineville, La Pine or Sisters OR orthodontic office, Dr. Quas, Dr. Wiater and Dr. Kang 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!

When we think orthodontics, we commonly think teeth. Naturally! Straight teeth and a beaming smile are everyone’s orthodontic goal. But orthodontics is a field which specializes in more than misaligned teeth. While your beautifully aligned teeth are the visible outcome of your orthodontic work, a properly aligned bite is the foundation for your healthy smile.

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when the mouth is closed. A malocclusion, or bad bite, affects many people to some degree, but not always in exactly the same way. Some of the different types of malocclusion include:

• Crossbite

A crossbite occurs when upper teeth fit inside lower teeth. An anterior crossbite refers to the front teeth, with one or more upper front teeth, or incisors, fitting behind lower front teeth. A posterior crossbite affects the back teeth, with upper teeth fitting inside the lower teeth on one or both sides of the jaw.

• Crowding

When the jaw is small and/or the teeth are large, lack of space can result in crowded, twisted, or crooked teeth.

• Open bite

An anterior open bite means that the front teeth don’t close when biting down, leaving an open space between the upper and lower teeth. A posterior open bite occurs when the back teeth don’t make contact when the front teeth close.

• Overbite

Our upper front teeth naturally overlap the lower ones a small bit when the teeth are closed. An overbite occurs when the upper teeth significantly overlap the lower teeth.

• Overjet

When the upper front teeth protrude too far forward over the bottom teeth, it’s called an overjet, or, sometimes, buck teeth. Where an overbite causes a vertical overlap, an overjet takes into account the horizontal relationship of the teeth.

• Spacing

A jaw that is large, teeth that are small, missing teeth—these conditions can lead to gaps between the teeth.

• Underbite

An underbite 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.

If you have a malocclusion, what comes next? This depends.

Some malocclusions are so minor that no treatment is necessary. Some are the result of misaligned teeth. Some occur because the upper and lower jaws are growing at different rates. Some are a combination of teeth and jaw misalignments. Some are caused by genetics, while others are caused by injuries or habits like prolonged thumb sucking or tongue thrusting.

Because malocclusions are so varied, your treatment plan will be designed for your specific needs. Braces, aligners, appliances like the Herbst® appliance or the palatal expander, surgery for severe malocclusions—there is a larger variety of treatment options than ever before to help you achieve a healthy bite.

When teeth and jaws don’t fit together as they should, the consequences can be damaged teeth and enamel, problems with the temporomandibular joint, headaches and facial pain, and difficulty chewing, eating, and speaking.

The good news is that early intervention for children can help correct teeth and jaw problems before they become more serious, leading to easier orthodontic care in the teen years, and helping to avoid the possibility of surgery or extractions. This is why Dr. Quas, Dr. Wiater and Dr. Kang and our team recommend an orthodontic assessment at our Bend, Redmond, Prineville, La Pine or Sisters OR office for children around the age of seven.

If you’re an adult with concerns about your teeth or bite, there’s good news for you, too. Dr. Quas, Dr. Wiater and Dr. Kang can devise a treatment plan to improve your bite and your smile no matter what your age.

Of course, despite our title, there’s really no such thing as a “common malocclusion” when we’re talking about your dental health. Each person—and each smile—is unique. Dr. Quas, Dr. Wiater and Dr. Kang will diagnose your malocclusion and create a personalized plan carefully tailored to your exact needs, for an uncommonly attractive, confident, and healthy smile.

Traditional braces and oral piercings—does the inevitable meeting of metals pose any risks? Let’s look at some of the potential problems with oral piercings, and you and Dr. Quas, Dr. Wiater and Dr. Kang can decide if you should take a break from jewelry while you’re in treatment.

• Tooth Damage

Enamel is the strongest substance in our bodies, but when up against constant contact with metal? It’s not a fair fight.

Tongue piercings, especially, cause problems for your teeth. Whenever you speak or eat—even while you’re sleeping!—your tongue is making contact with your teeth. This continual tapping of metal on enamel can chip and crack teeth and damage fillings. A serious fracture could mean a root canal.

You’re getting braces to create a more attractive, healthy smile, so keeping your teeth intact is a priority.

• Gum Problems

Your gums are affected by orthodontic treatment. As the teeth move, the gums, ligaments, and bone around them adapt and even reshape over time. You might notice when you first get your braces, or when you go in for an adjustment, that you have a few days of swollen, sensitive gums afterward. You might also find that you are at greater risk of gingivitis, because it can be harder to keep plaque away from your gumline until you perfect your brushing and flossing skills.

Oral piercings bring their own gingival dangers. Jewelry in the tongue or lip can rub against gum tissue, especially around your lower front teeth. As the gum tissue continues to be irritated and inflamed, it pulls away from the teeth. This process is called gum recession.

Receding gums expose the tops of your roots to cavity-causing bacteria. They make you more sensitive to hot or cold foods. Pockets between gums and teeth can harbor infections that threaten the tooth itself.

Caring for your gums during braces is important for your dental health. Since people with oral piercings have a much higher rate of gum recession that those without, why add one more risk factor to your oral health?

• Metal vs Metal

Lip and tongue piercings can make contact with traditional brackets and wires, especially if you have a habit of playing with them. And let’s not forget lingual braces! Lingual braces are almost invisible because their brackets and wires are custom fitted to the back of your teeth. Whenever you speak or eat, you’ll be taking the chance that a tongue piercing will damage these custom-made appliances.

Dr. Quas, Dr. Wiater and Dr. Kang can tell you if your piercings are in any danger of interfering with your braces, but even if you’re planning on aligners, there are additional reasons to consider retiring your oral jewelry. Dental associations and medical associations discourage oral piercings because they can damage teeth and gums. And there’s more. Oral piercings can lead to swelling, bleeding, allergic reactions, infection, and nerve damage.

The reason you’re considering braces is because you want a healthy, attractive smile. Don’t let a tiny piece of jewelry make your life and your treatment more difficult! Do some research and talk to our Bend, Redmond, Prineville, La Pine or Sisters OR team about your oral piercings, and come up with a solution that’s best for your health and best for your smile.

Summer means sun and heat and delicious, frosty treats to keep you cool while you’re enjoying the sun and heat. If you’re wearing braces this summer, not to worry! Dr. Quas, Dr. Wiater and Dr. Kang and our team have plenty of ideas for icy treats to help you beat the heat.

• Fruit Smoothies

Low on refined sugars, high on vitamins and minerals, refreshing, delicious, easy on brackets and wires—what’s not to like about fruit smoothies? And if you want to up the nutritional value by adding some green vegetables to the blender, even better!

If you’re buying your smoothie instead of making it yourself, watch out for added sugars in ingredients like ice cream, sherbet, frozen yogurt, and sweetened fruit juice. It can be more challenging to keep your teeth clean with braces, so watching your sugar intake is more important than ever. Try a smoothie made with low-fat yogurt, fruits and/or vegetables, and 100% fruit juice instead. Just as delicious, without extra tablespoons of added sugar.

• Iced (Herbal, Green, or White) Tea & Frozen Coffee Treats

Coffee and black tea contain compounds called tannins, which can stain tooth enamel and braces. Using a straw can help you limit your enamel’s exposure. If you enjoy a cold, iced beverage occasionally, consider green, white, or herbal iced teas. They don’t stain as much, and many contain healthy antioxidants and other health benefits.

And if you can’t resist that creamy iced coffee beverage? Use a straw to avoid bathing your teeth in the stain-causing tannins and enamel-weakening acids found in coffee. Because these drinks can be full of added sugars, consider reduced-sugar options and skip the toppings.

• Frozen Treats

When you hear that familiar tune coming from the neighborhood ice cream truck, do you have to stand on the sidewalk, sadly watching it disappear into the distance? Not necessarily!

Milk shakes, ice cream, and frozen yogurt are a refreshing choice in a braces-friendly form—and they contain calcium. Popsicles and fruit bars can be a safe choice if you don’t bite into solid ice. You wouldn’t chew on ice because it could damage your braces, so make sure your frozen bar softens a bit before you enjoy it.

What kinds of frozen treats to avoid? If your favorite flavor of ice cream or your go-to ice cream bar contains hard or chewy additions like nuts and pieces of candy, choose another item from the menu. Surrounding nuts and candies with ice cream doesn’t actually make them any safer for your brackets and wires, and may lead to an unplanned visit to our Bend, Redmond, Prineville, La Pine or Sisters OR orthodontic office to fix a broken bracket.

We don’t recommend a steady diet of sweet treats, because you want a cavity-free smile when your braces come off. And water is always an excellent summertime choice for both hydration and health. But an occasional frosty dessert is cool and tasty and soothing, especially if you’ve just had an adjustment. Just be sure to brush—or rinse with water if you can’t brush—after indulging. Now, what’s on the menu for fall?
