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. Roger Elton 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 Parker or Aurora, CO orthodontic office, Roger Elton 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!

You and your braces will become good friends over the coming months or years, so it’s important to get your relationship off to a good start. Consider the following recommendations to prevent rocky times ahead:

1. Floss, floss, floss. Yes, it’s a pain to floss around your braces, but it's the best way to prevent gum disease and other oral health problems. Ask Roger Elton and our staff for floss threaders to make the chore easier. Just a few minutes per day will ensure that you don’t face significant dental health issues when the braces come off.
2. Avoid sticky or hard foods. It’s tough to forgo toffee, caramel, gum, and other favorite sticky treats, but your braces will thank you. Sticky or hard foods can break a bracket or wire, so it’s best to avoid them altogether.
3. Chew with your back teeth. If you’re used to taking large bites with your front teeth, it might be time to switch your eating habits. Taking a large bite of food with your front teeth can leave your braces vulnerable to damage. Instead, cut large foods into pieces and use your back teeth to chew. This is especially important with corn on the cob, which should always be cut from the cob.
4. Wear rubber bands and headgear. Rubber bands, headgear, and other orthodontic appliances may seem annoying, but failing to comply with wearing them can increase the length of your treatment by months. Wear them now to avoid problems in the future.

Somewhere in a bathroom drawer or medicine cabinet, we all have one—that little plastic dental floss dispenser. And whether you use your floss every day (yay!), or have completely forgotten it was in there (not so good), just how much do you know about that sturdy string? Let’s find out!

• Flossing has been around for hundreds of years.

FACT: It’s been just over two hundred years since Dr. Levi Spear Parmly, a dentist in New Orleans, suggested his patients use waxed silk thread to clean between their teeth. This is considered the first “official” invention of dental floss, although using some form of tool to get rid of food particles between the teeth has been around since prehistoric times.

• Brushing well is the same as flossing.

FICTION: It’s really not. While brushing does a great job of cleaning food particles, plaque, and bacteria from your enamel, there are some places those bristles can’t… quite… reach. Floss was designed to clean plaque and food from between the teeth and close to the gum line where your brush doesn’t fit.

• There’s more than one way to clean between your teeth.

FACT: Indeed there is! Not only are there many varieties of dental floss (waxed, flavored, round, flat, thick, thin, in a dispenser, attached to miniature floss wands), but you have alternatives if using any kind of floss is difficult for you. Water-flossers direct a pulsing stream of water between and around the teeth and gum line to remove food particles and plaque. Another useful alternative is the interproximal brush, a tiny little cone-shaped brush designed to remove food and plaque from those hard-to-reach spots.

• It’s impossible to floss with braces.

FICTION: Untrue—but it can be more challenging! That’s why there are any number of flossing products designed to work with and around your braces. Stiff strands of floss which work like dental picks, floss threaders, water flossers, and interproximal/interdental brushes can both clean between your teeth and remove food particles and plaque where they collect around your braces. Roger Elton can suggest some great options to work with your individual orthodontic treatment.

• Flossing helps prevent gum disease.

FACT: Scientific studies haven’t provided definitive answers. But dental and periodontal associations strongly recommend daily flossing as one of the most important things you can do to prevent gum disease. Gingivitis, or mild gum disease, is caused by irritated, inflamed gum tissue. Gum tissue becomes irritated and inflamed as a response to the bacteria, plaque, and tartar that stick to your teeth. Anything you can do to help remove these irritants will reduce your risk of gum disease.

• Flossing helps prevent cavities.

FACT: Dentists strongly recommend daily flossing to remove the food particles and plaque that lead to cavities. Brushing removes cavity-causing plaque from the outer surfaces of your teeth. But there’s a lot of enamel between your teeth as well. Flossing removes plaque from these hidden spots, helping to prevent interproximal (“between the teeth”) cavities from forming.

• Bleeding when you floss is normal.

FICTION: Bleeding isn’t a typical reaction to flossing. Bleeding gums could be an early sign of gum disease caused by plaque and tartar buildup. On the other hand, if you floss too hard, or go too deeply below the gum line, you can make delicate gum tissue bleed. Ask Roger Elton for tips on perfect flossing technique.

• You need to floss after every meal.

FICTION: Dental professionals generally recommend brushing twice a day and flossing at least once each day. But this suggestion comes with some exceptions. Since you have braces, Roger Elton might recommend flossing whenever you have a meal or snack.

• Your dentist will never know that you haven’t been flossing.

FICTION: Nope. Sure, you can miss flossing a few times and catch up before your appointment at our Parker or Aurora, CO office. But built-up plaque between the teeth, red, swollen, or bleeding gums, and gingivitis and interproximal cavities let both you and your dentist know that you’ve been neglecting good dental habits.

• It’s never too late to start flossing!

FACT: Flossing is a simple, quick, and inexpensive way to maintain tooth and gum health. If you haven’t had much luck flossing in the past, ask Roger Elton for flossing tools and techniques that will work for your specific needs. Start now, and see what a difference it will make at your next checkup!

If you had all these flossing facts at your fingertips, congratulations! But if you didn’t, no need to worry, because the real test of your knowledge is in its application. Flossing properly at least once each day will give you something far more rewarding than blog-quiz kudos—you’ll see that regular flossing rewarded with healthier teeth and gums!

Well, of course you can chew gum and wear braces. But, should you chew gum and wear braces? That can be a sticky question.

For many years, the answer was a firm “No.” Not only did our favorite chewables literally gum up the (dental) works, but they were filled with loads of the sugar that cavity-causing bacteria love to feed on. The result? A much better chance of damage to your orthodontic work, and a higher risk of cavities near your brackets and wires.

But times, and gum recipes, change. Today’s sugar-free gum provides us with some new ideas to chew over.

• Sugarless gum is much less sticky than regular gum, so it is much less likely to stick to your appliance. If there is any chance that gum will damage your wires or brackets, we’ll let you know that it’s best to wait until your braces are off to indulge.
• Some orthodontic patients find that their jaws and ligaments are less sore if they chew gum for a few minutes after an adjustment.
• Most important, studies suggest that chewing sugarless gum might actually help prevent cavities from forming. How is that possible?

Because chewing gum increases our production of saliva! Okay, we don’t normally find saliva an exciting, exclamation-point-worthy topic, but let’s look at the dental benefits:

• Saliva washes away food particles and bacteria. And because braces can trap food when we eat, it’s great to have some help washing away any meal-time souvenirs.
• Saliva helps neutralize acids in the mouth. The acids found in foods and produced by oral bacteria lead to cavities, so diluting and neutralizing their effects provide important protection for our enamel.
• Saliva helps bathe the teeth in minerals that can actually rebuild weakened enamel. Acids in the mouth attack minerals in the enamel such as the calcium and phosphate that strengthen our teeth. Fortunately, saliva provides calcium, phosphate, and fluoride that can actually help rebuild weakened enamel.

So, should you chew gum and wear braces? The real question is, should you chew gum while you’re in braces? Roger Elton and our team are more than happy to provide the right answer for you! Talk to us at your next visit to our Parker or Aurora, CO office about the potential benefits and drawbacks of dentist-approved sugarless gum. Depending on the kind of gum you choose and the kind of orthodontic work you are having done, the answer just might surprise you.
