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. Dennis Johnson 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 Columbus, OH orthodontic office, Dr. Dennis Johnson 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!

If there’s one meal that can claim the title of “Sweetest Meal of the Day,” it’s almost certainly breakfast. Sugary cereals, syrup-covered waffles, oatmeal with honey, cinnamon toast (which is literally sugar poured on toast)—it’s hard to imagine another menu even coming close. But you’re trying to keep your diet as healthy as possible. What to do?

First, no need to deprive yourself of the occasional pastry or stack of pancakes. The real problem with breakfast isn’t so much sugar as it is added sugar.

• Just a Spoonful of Sugar? What’s So Bad About That?

Nothing! Many healthy foods have natural sugars. Milk contains lactose sugar, and it also contains calcium and is enriched with vitamin D—both of which are essential for strong bones and teeth. Fruits get their sweetness from a sugar called fructose, and deliciously provide vitamins, minerals, antioxidants, and fiber to our diets.

Even processed sugar is surprisingly low in calories. In fact, a teaspoon of white sugar has only about 15 calories. But this teaspoon is also rich in nutrients for cavity-causing bacteria. The oral bacteria in plaque use sugars and carbohydrates from food particles as a fuel source to produce acids. These acids erode enamel and lead to cavities.

Choosing breakfast foods without additional sugars, then, is an easy way to reduce the number of empty calories in your diet while safeguarding the health of your teeth. We have a few suggestions.

• Be Selective with Cereals

If the word “sugar” or “honey” or appears on the box, that’s a hint that your favorite cereal is heavy on the sugar. But there’s a more scientific way to tell just how much sugar is in that spoonful.

While the colorful packaging and playful mascots are eye-catching, check the black-and-white panel with nutritional facts found on every box. If one serving equals 27 grams, and the sugar in that serving equals 15 grams, you know you have a problem. And cereals marketed to children are especially “rich” in added sugar.

But luckily, you don’t need to give up your morning bowl. Many cold cereals are available that offer whole grains, protein, and fiber without a lot of added sugar. Spend some time in the cereal aisle comparing, or, to make life easier, there are many online sites which recommend the best (and worst) cereals in terms of sugar content.

• Use Your Judgment with Juices

Fruits are packed with important nutrients. Not only do they provide essential vitamins and minerals, they’re a great source of water and fiber. If you drink 100% fruit juice, you are getting the benefit of most of the vitamins and minerals found in fruit. (You’re also getting less of the fruit’s natural fiber, and more of the fruit’s natural sugar, so consider fresh fruit as an option occasionally.)

But when fruit juice comes with “cocktail,” or “punch,” or “ade” attached to the end of it, there’s often something else attached—added sugar. For natural fruit flavor and the least amount of sugar, stay with 100% unsweetened fruit juice.

• Search Out “Surprise” Sugars

Remember the childhood excitement of searching through your cereal box for the prize inside? Fun! What’s not so much fun? The surprises you might find when you search through the labels on your favorite breakfast items—because added sugars make their stealthy way into many of our morning favorites.

When you compare plain, Greek, and low-fat yogurts, for example, the low-fat options are often higher in added sugar. A container of low-fat yogurt can provide 19 grams of sugar—that’s a tablespoon and a half!

And while you’re at it, be sure to compare the sugar content in granola bars. Some are full of nuts and grains, and some are full of added sugar.

Going out for a breakfast smoothie? Those can contain 70 grams of sugar and more. Making your own at home might be a little more time-consuming, but if you use fresh fruit as your sweetener, you can make sure that what you’re not consuming is added sugar. If you’re on the go, check out all-fruit options at your favorite smoothie shop.

Dr. Dennis Johnson and our team aren’t asking you to eliminate sugar from your breakfast diet altogether. (Everyone loves a doughnut now and again.) But substituting some alternatives for your regular menu choices can reduce the amount of added sugars by tablespoons every meal. That’s another great reason to greet the morning with a smile!

You’ve selected the Invisalign system because of the many benefits Invisalign offers: comfort, convenience, appearance, and even potentially shorter treatment time! And to add to the good news, caring for your Invisalign aligners is easy and uncomplicated. Follow these simple tips to keep your aligners in the best possible shape as you move through the stages of your treatment.

Stay Clean

• Always brush and floss your teeth before using your aligners so that bacteria and food particles will not have a chance to collect around your teeth while you wear them.
• When you brush your teeth, be sure to brush your aligners with a separate soft toothbrush and lukewarm water as well.
• Rinse your aligners whenever you remove them during the day.
• Soak your aligners as recommended. Use the Invisalign Cleaning System or ask our Columbus, OH team for other suggestions to keep your aligners free from odor and bacteria.

Stay Clear

One of the reasons you chose Invisalign is for an almost invisible appearance. Why take a chance on discoloration or scratches that will make the appliance more noticeable? Here are some common mistakes that can affect the color of your aligners:

• If your aligner has white spots, that might mean plaque build-up. Always rinse your aligner after you remove it and clean it thoroughly night and morning.
• Brushing with anything other than a soft brush and brushing too hard can cause scratches in the material which might be noticeable. A gentle touch will work to clean and protect your aligners.
• Eating with Invisalign aligners can cause staining. More important, it can cause the retention of food particles in the appliance, which can lead to dental problems. Finally, aligners are not meant for chewing—they might be damaged or lose their ideal shape even with soft foods. If you are going to be eating or drinking, take your aligners out, give them a rinse, and brush before you replace them. Or stick with water! Water will have no ill effects on teeth or aligners.
• Only soak aligners in an appropriate solution. Harsh chemicals, colored mouthwashes, and even some toothpastes can dim or discolor the clear plastic.

Talk to Dr. Dennis Johnson about the best products to use and the best methods for taking care of your aligners. After all, making the process of improving your smile as easy and effective as possible is yet another benefit of choosing Invisalign!

The Fourth of July is a great time to get together with friends and family members for BBQ, games, fireworks, and other celebrations in honor of our country’s independence. While your fellow revelers eat hot dogs and wave flags, you can impress them by sharing these fascinating facts and historical tidbits about some of our country’s traditions and symbols from the team at Johnson Orthodontics.

The Statue of Liberty

With a torch in one hand and a tablet in the other, the Statue of Liberty is one of the most iconic and recognizable symbols of our country. However, as recognizable as certain parts of the statue are, not many people know that broken shackles, which represent oppression and tyranny, are lying at Lady Liberty’s feet. According to the Statue of Liberty-Ellis Island Foundation, the copper-plated lady weighs in at a whopping 450,000 tons and has been holding her torch up for more than 125 years, which must make for some impressive arm muscles.

Nathan’s Hot Dog Eating Contest

Since 1916, people have been flocking to Coney Island on the Fourth of July to witness what some people call the “superbowl of competitive eating.” Nathan’s Hot Dog Eating contest challenges competitors to devour as many hot dogs as they can in just ten minutes, with the current record holder swallowing a whopping 68 hot dogs! If you’d like to witness this bizarre and frenzied eating competition but you won’t be anywhere near Coney Island on the fourth, don’t worry. ESPN has been broadcasting this popular event for several years, so you can watch from the comfort of your couch while you eat a reasonably portioned meal.

The History Behind Fireworks

Viewing the nighttime fireworks display is exciting way to finish off the fourth. Many people know that these brilliant displays probably originated with the Chinese. However, many historians also believe that fireworks were stumbled upon when the Chinese roasted bamboo sticks over fires and watched them explode. After many years of roasting the sticks, a group of alchemists created an early form of gunpowder, which they stuffed into the bamboo sticks to create an even more powerful explosion, paving the way for the today’s modern fireworks.

Whether you’re planning on visiting the Statue of Liberty, watching fireworks in Columbus, OH, or even participating in a hot dog eating contest, Dr. Dennis Johnson and our team hope you have a safe and fun-filled holiday. Happy Fourth of July!
