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. Thomas Burns 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 Westfield, NJ orthodontic office, Dr. Thomas Burns 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!

Also known as onchophagia, the habit of nail biting is one of the so-called “nervous habits” that can be triggered by stress, excitement, or boredom. Approximately half of all kids between the ages of ten and 18 have been nail biters at one time or another. Experts say that about 30 percent of children and 15 percent of adults are nail biters, however most people stop chewing their nails by the time they turn 30.

Here are four dental and general reasons to stop biting your nails:

1. It’s unsanitary: Your nails harbor bacteria and germs, and are almost twice as dirty as fingers. What’s more, swallowing dirty nails can lead to stomach problems.

2. It wears down your teeth: Gnawing your nails can put added stress on your pearly whites, which can lead to crooked teeth.

3. It can delay your orthodontic treatment: For those of our patients wearing braces, nail biting puts additional pressure on teeth and weakens roots.

4. It can cost you, literally: It has been estimated that up to $4,000 in extra dental bills can build up over a lifetime.

Dr. Thomas Burns and our team recommend the following to kick your nail biting habit:

• Keep your nails trimmed short; you’ll have less of a nail to bite.
• Coat your nails with a bitter-tasting nail polish.
• Ask us about obtaining a mouthguard, which can help prevent nail biting.
• Put a rubber band around your wrist and snap it whenever you get the urge to gnaw on your nails.
• Think about when and why you chew your nails. Whether you are nervous or just bored, understanding the triggers can help you find a solution and stop the habit.
• If you can’t stop, behavioral therapy may be an effective option to stop nail biting. Ask Dr. Thomas Burns and our team for a recommendation.

When you’re busy at school or work, when you’re on vacation, when you’re on the road to adventure—preparation helps everything go smoothly. Especially when the unexpected happens! So, how can you be prepared for any orthodontic and dental situations which might arise? By creating these useful—and portable—travel kits.

Everyday Basics Kit

Dentists recommend brushing twice a day and flossing at least once each day for clean and healthy teeth. But after a long day at school or work with no time to head home before your date, or a garlic-heavy lunch in the cafeteria, or a dash from the classroom to after-school activities, you might feel like there’s no time like the present to give your smile a bit of a boost.

Be prepared with a small travel bag filled with these easy-to-carry basics to get you through your busy day with clean teeth, fresh breath, and a confident smile:

• Toothbrush and case—and do make sure your case is ventilated so your brush can air dry. Bacteria love a closed, damp environment!
• Toothpaste
• Mini-bottle of mouthwash
• Small mirror—to check for any lunch leftovers
• Dental floss—to remove any lunch leftovers. Use braces-friendly dental floss if you have traditional braces.
• Dental Wax—to cover any uncomfortable wires or brackets
• Interproximal brushes—to remove food particles from around your braces and between your teeth
• Extra rubber bands
• Aligner/Retainer case—keep your aligner or retainer safe and clean while you’re eating

Flight Gear

Getting set to travel by air again after this long lay-over? Your basic kit will do the job with just a few minor additions and alterations.

• A travel version of your manual or electric toothbrush and travel case
• Plug adapter or voltage converter as needed for your electric brush if you’re visiting another country
• Quart size, resealable plastic bag to hold your carry-on supplies. Toothpaste and mouthwash are included in the list of items which need to fit carry-on guidelines.
• Travel-size toothpaste—3.4 oz (100 ml) or smaller tube size. (And an almost-empty regular size tube doesn’t count!)
• Travel-size mouthwash—also in a 3.4 oz (100 ml) or smaller container
• Our Westfield, NJ office’s phone number. In case of emergency, Dr. Thomas Burns can give you advice on how to handle any problem which might arise when you’re far from home.

Looking for Adventure?

If you’re camping in the forest, leaving for the lake, going for a road trip, or heading out on any travel adventure, you’ll be bringing the dental care basics, of course. We’d also like to recommend some items to take along in the event of a dental emergency while you’re away from home:

• Dental mirror
• Cotton rolls
• Over-the-counter pain relief—including a tube of oral pain relief gel
• Ice pack
• Dental wax—this handy item not only protects against sharp wires, it can cover the sharp edges of a broken bracket
• Temporary fillings—to protect your sensitive tooth if a filling or crown is lost
• Tooth preservation kit—to protect a dislodged tooth in case it can be reimplanted. (This means seeing a dentist very quickly, usually within 30 minutes of the accident.)

And, if you’ll be mountain biking, water skiing, or enjoying any activity where there’s potential for impact, don’t forget to pack your mouthguard!

Preparation is key to eliminating a lot of stress in our daily lives, and who couldn’t use a bit of stress-relief these days? Make room in your bag, locker, desk, luggage, or backpack for some portable, lightweight dental necessities. Be prepared to share your confident, healthy smile no matter what life has in store!

You may have a talent for home repairs. You may be able to rebuild your computer. You may even be able to put together a whole room of furniture armed only with flat-box kits and an Allen wrench. But, please—don’t try do-it-yourself orthodontics!

Now that generic clear aligners are available, you might consider giving them a try to save some money. But is straightening your own teeth really a good idea? Before you are tempted, let’s look more closely at the products and the dental science involved.

Invisalign®

• Invisalign clear aligners are used by orthodontists and dentists with experience in custom treatment for your smile. A 3D image of your teeth will be captured by the iTero Element® scanner. Using special software, your doctor can map out each projected shift in your teeth, and even show you a projection of your finished smile!
• Your Invisalign aligners will be tailored to fit your teeth precisely using the 3D scan and 3D printing. They are made from SmartTrack® material, a product specifically engineered for a perfect, comfortable fit. Invisalign aligners are even trimmed to fit your individual gumline to prevent irritation.
• When your first sets of Invisalign aligners arrive at our Westfield, NJ office, Dr. Thomas Burns will check for fit, answer any questions you might have about use and care, and let you know what to look for and what to expect. Your progress will be monitored with visits every six to eight weeks. (And for parents of teens, Invisalign aligners can offer blue “compliance indicators” to let you know they are being worn the 20-22 hours a day necessary for the best and fastest results.)

Generic Aligners

• You might be required to make a putty mold of your own upper and lower teeth, which is not the easiest thing to do well, and to take selfies of your teeth.
• The aligners will be sent to you in the mail. They are generally made of hard plastic with generic gumlines. There will be no one to tell you if the aligners fit properly.
• They are sometimes less expensive because there is no in-person medical supervision. A dental professional working for the company will look at the model created from molds you submit, and recommend a series of aligners to correct the problems he detects by looking at the model and your selfies. This supervisor will not be able to assess the overall dental health of each patient to make sure teeth and gums are healthy and ready to start treatment, and will not be able to tell if the teeth are moving properly or improperly once the aligners are in use.

Finally, while generic aligners may potentially have some success in minor tooth straightening, they are not created to deal with complex bite issues or malocclusions.  In fact, using generic aligners with no supervision can cause more serious dental problems than a patient started with.

Sure, sometimes a do-it-yourself project turns out well. But your teeth and bones are too important for home improvement. When it comes to creating a beautiful, even smile and balanced, comfortable bite while making sure of your dental health, it’s always best to trust a professional like Dr. Thomas Burns to provide you with gentle, tested, and successful care!
