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. Geller 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 Plano, TX orthodontic office, Dr. Geller 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 may have noticed that we specialize in orthodontics and dentofacial orthopedics. And while most people we talk to have heard of orthodontics, many are confused by the dentofacial orthopedics part of the title. Today, Dr. Geller and our team thought we would explain the difference.

While orthodontics entails the management of tooth movement, dentofacial orthopedics involves the guidance of facial growth and facial development, which occurs for the most part during childhood, and is a reason why kids are often the best candidates for receiving dentofacial orthopedic therapy. Dr. Geller will examine and monitor your child’s growth to determine when starting treatment will be most effective. If your child begins orthodontic treatment before his or her adult teeth have erupted, it is known as Phase-One treatment. During this phase, Dr. Geller will use treatments designed to correct your child’s jaw growth and make sure that the jaw bone is properly aligned before beginning the next phase of treatment, which usually involves placing braces to straighten your child's teeth.

Dentofacial orthopedics is also used to treat adult patients at Geller Orthodontics, however, this process may involve surgery. With our younger patients, we know the jaw bones are still forming, making it easier for our team at Geller Orthodontics to control bone growth and tooth movement. Adults, however, are a different story; their bones are no longer growing, and their jaw bones have hardened, so it is more difficult to adjust the bite and move teeth into proper alignment. Dr. Geller may recommend surgery to adjust the jaw bone and establish the proper bite alignment before beginning treatment.

Because our team at Geller Orthodontics is skilled in both areas, we are able to diagnose any misalignments in the teeth and jaw as well as the facial structure, and can devise a treatment plan that integrates both orthodontic and dentofacial orthopedic treatments.

We hope that helps! To learn more about dentofacial orthopedics, and to find out if this type of treatment is right for you, please contact our Plano, TX office and schedule an initial consultation for you or your child. It’s never too late to get a great smile, and we can’t wait to help you or your child get started.

How better to spend the fall months than inside by the fireplace with a warm cup of cider and a book in hand? Dr. Geller and our team at Geller Orthodontics encourage you to warm up your mind this fall season with a few great books. Sure it may be easy to put off reading when balancing a hectic schedule, but reading is vital to brain development. Besides, reading is always a blast!

This week, we thought we’d ask what you or your child are reading this fall. Do you have any suggestions for must-read books this year? Out of ideas for great fall reads? Ask us for suggestions, and we would be happy to provide a few. You may also ask a local librarian here in Plano, TX for some ideas.

Happy reading! Be sure to share with us your fall picks or your all-time favorites below or on our Facebook page!

What does the month of October mean to you? For people in the northern hemisphere, October is when the weather starts to get a little chilly: heavy jackets might come out of storage and the summer clothing gets packed away. You might start making plans for the upcoming holidays or looking at the beautiful and changing autumn scenery. October means something a little different to our team at Geller Orthodontics because this is National Orthodontic Health Month. During October, orthodontic clinics all over the country work together to promote their services and inform the community about the important work we do.

National Orthodontic Health Month is an awareness campaign created cooperatively by orthodontists and other dental health professionals. During this month, we make a special effort to promote dental health and orthodontic health in particular. This is a great time to get your questions answered by dental professionals in your community and to learn more about exactly what an orthodontist can do for you and your family. Events held in connection with National Orthodontic Health Month are also an opportunity for us orthodontists to come out and meet community members. If you have never been to an orthodontist before, you might not know what to expect. Meeting one of us in person before your checkup is a great way to find out what kind of person you’ll be seeing during your appointment.

Meeting Dr. Geller in a relaxed “meet and greet” atmosphere can be especially helpful for any young orthodontic patients in your family. Kids of all ages–and their parents!–can feel anxiety about going to the dentist. Getting to know the person you have an appointment with can make the experience a lot less stressful for everyone. We don't want anyone to avoid seeing a dental professional for regular checkups just because they don't know who we are. Just meeting and talking with the orthodontist you'll be seeing may be enough to make you feel more comfortable about your upcoming appointment.

Dental health is something that affects everyone; healthy teeth and gums contribute to a healthy smile and a lifetime of comfort and well-being. Orthodontists are just one of the various dental practitioners you could visit at some point in your life, so taking a little time to learn who we are and what we do is certain to be a helpful experience. We look forward to seeing you and your family this October at our Plano, TX location!
