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. Drs. Magda Barnard & Lee Erickson 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 Bedford, NS orthodontic office, Drs. Magda Barnard & Lee Erickson 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!

It's almost game day and you're wondering what to put on the menu for your guests. Most snacks are typically highly processed and unhealthy. Why not mix it up this year and opt for some snacks that promote good oral health? Here are some of Drs. Magda Barnard & Lee Erickson favorites!

• Apples, carrots, celery, and cucumbers: These foods and other crispy, fibrous, fruits and vegetables are an excellent choice for the big game. Not only are they rich in vitamins and minerals which your body and mouth need, they are also known as detergent foods because of the cleaning effect they have on the teeth and gums. Try apples wedges spread with peanut butter and sprinkled with cinnamon.
• Beans: Beans are filling because they are packed with fiber and that keeps you from opting for sugary or fatty snacks. Along with fruits and vegetables, beans should be one of the stars of your game-day snack lineup. How about some hearty chickpea hummus with cucumber chips?
• Nuts like almonds, walnuts, pistachios, and cashews: Nuts abound in the minerals that help keep your teeth and gums strong like calcium, magnesium, and potassium. Put out a bowl of raw or roasted nuts for your guests as a crunchy, satisfying alternative to chips or crackers. Recent research even shows that the polyunsaturated fatty acids in nuts may help prevent gum disease. But remember not to eat the whole bowl! Nuts are very high in calories and a little goes a long way. Enjoy and handful or two along with your other healthy snacks.
• Dark chocolate: This one may be hard to believe at first, but research shows chocolate can be great for your teeth and help prevent decay! Now don't run off and start stocking your pantry with a bunch of that super sweet stuff, because these benefits come mainly from the tannins, polyphenols, and flavonoids present in the cacao bean. Dark chocolate is the least processed variety of chocolate and the closest to the cacao bean, so make sure you purchase a variety that is listed as 70% cocoa or more for these benefits. Like with nuts, chocolate is easy to overdo — aim to eat two or three squares.

Winter and its snowball fights are behind us, true, but there might be another kind of snowball heading your way. When you neglect the small steps involved in your everyday orthodontic routines, little problems can start to snowball into bigger ones, affecting your dental health and delaying your orthodontic progress.

Here are three areas where letting the small steps in your routine slide can have consequences:

Dental Hygiene

It can be harder to get your teeth their cleanest while you’re wearing braces. After all, there are wires to get behind and brackets to brush around, and you still need to get that floss in between your teeth. But neglecting your dental hygiene can have big consequences:

• Demineralization

The bacteria in plaque create acids that strip the minerals from tooth enamel. This process is called demineralization. Wherever plaque is allowed to build up, you’ll start to see white spots in the enamel. This discoloration is a sign that minerals are missing, and is often found around brackets, where it’s harder to brush. White spots can be treated cosmetically, but better to avoid them as much as possible, because eventually they can become . . .

• Cavities

As demineralization continues, the enamel becomes weaker and weaker, until a hole forms in the tooth—a cavity. Besides damaging your tooth, a cavity can put you behind your orthodontic schedule if you need parts of your braces removed for treatment.

• Gum Disease

When plaque builds up around the gums, gum tissue becomes inflamed and irritated—this is gingivitis, or early-stage gum disease. Symptoms often include puffy gums, redness, bleeding, and bad breath. Mild gum disease becomes more serious over time, so treat gingivitis early—or, even better, prevent gum disease with careful brushing and flossing.

Looking After Your Appliances

• Follow Care Instructions

Orthodontic appliances need love, too! Any instructions you get for their care are for a good reason. Brackets can become loose when you bite down on chewy foods. Wires can break when you eat hard candy. Aligners can warp if you leave them on a hot dashboard. If you follow instructions carefully, you won’t need to postpone your progress while you wait for repairs.

• Use Your Protective Case

If you wear aligners, or a removable appliance, or a retainer, don’t forget to protect these items when you’re not wearing them. This means placing them in their cases, not wrapped in a napkin on your lunch tray, or in the bottom of your gym bag, or anywhere your dog can reach them!

• Be Proactive If Accidents Happen

Unfortunately, accidents do happen, and loose brackets, broken wires, lost ligatures, and cracked or warped aligners can interrupt orthodontic progress and cause you pain and discomfort. Give our Bedford, NS orthodontic office a call to see if minor damage to an appliance can be handled at home, or whether you should be seen before your next regular appointment for repairs.

Following Your Orthodontic Plan

There’s more to following your orthodontic schedule than arriving on time for appointments. Depending on your treatment, you might be responsible for keeping track of the time you spend wearing:

• Elastics

Elastic bands can be used to help align your upper and lower jaws. If you don’t wear your bands as directed, you won’t make progress as quickly as you could. And remember to replace your elastics as often as recommended, because after hours of s-t-r-e-t-c-h-i-n-g they lose their effectiveness.

• Aligners

Most aligners are worn for around 22 hours each day. If you don’t follow your orthodontist’s instructions and wear your aligners for the recommend hours each day, your teeth won’t be in the proper alignment when your next set of trays is ready to begin work.

• Retainers

If you have a retainer and don’t wear it, your teeth will start to shift position. Skip wearing your retainer long enough, and you might need a return to your braces or aligners to repair any new misalignment.

Don’t ignore what seem like little dental and orthodontic responsibilities. Keep up with daily cleaning and brushing, take care of your appliances, and follow your orthodontic plan, and you’ll finish your treatment with a beautiful and healthy smile—right on schedule.

Crooked or crowded teeth aren’t always just a cosmetic issue; they also are more difficult to clean, which can lead to tooth decay and gum disease. Likewise, if your teeth don’t align properly when you bite (known as malocclusion), this can cause chewing, swallowing, and speaking problems.

You can put these risks to rest and look amazing, however, with well-thought-out orthodontic treatment from Drs. Magda Barnard & Lee Erickson. More and more adults are opting for orthodontic treatment and changing their lives in the process.

Childhood is of course the ideal time to get treatment, since the mouth and jaws are still growing, but many adults still can get beautiful and lasting results which can be achieved discreetly and effectively with modern orthodontic appliances and technologies.

Traditional braces used to be the only thing going, and many adults understandably don’t like the way they look. There are so many other options for braces these days that it’s possible for almost any patient to be treated effectively and efficiently — usually in one to two years.

Here are some of the technologies being implemented in our modern Bedford, NS orthodontic office:

• Clear aligners: Practically invisible clear plastic aligners are great for less severe cases.
• Lingual braces: These are placed on the back of your teeth instead of the front, and can handle anything that traditional braces can.
• Ceramic braces: Translucent ceramic brackets make for effective and more discreet treatment.
• Self-ligating braces: These require less manipulation by the orthodontist, which means fewer appointments and quicker results.

It should also be noted that the goal of orthodontic treatment (especially in adults) isn’t always limited to straightening teeth and/or correcting a bite. Teeth provide support for the lips and cheeks and help define your face.

The relationship between the jaws, teeth, face, soft tissues, and underlying skeleton of the face are important, and an orthodontist takes this into account when designing a smile.

In short, getting orthodontic treatment won’t just give you a good-looking and healthy smile; it can help define and enhance the entire appearance of your face. Knowing just how crucial your teeth are in determining how you look and live will help you age positively and confidently.
