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. Lowder 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 Idaho Falls, Rigby, Rexburg, Afton, and Salmon orthodontic office, Dr. Lowder 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!

Proper mouth protection is recommended by Lowder Orthodontics when you participate in any sports activities. If you wear braces, this protection becomes essential. Injuries to your mouth can not only damage your teeth, but your braces could break and cut open your lip.

Full Facial Guards

Full facial guards are often used in football and offer protection to your mouth from most injuries. Even with full facial protection, you may benefit from additional mouth protection. While your face is protected from outside impact, you could still suffer from cuts or damage to your braces from internal impact.

Mouthguards

Mouthguards referred to as boil-and-bites can be purchased at many retail stores. As the name implies, these guards are boiled in water to heat and soften the material. While the guard is still warm, you place it in your mouth and bite down gently. This causes the guard to form to the shape of your mouth. Unfortunately, these guards do not necessarily offer the best protection or fit.

Dr. Lowder can make custom mouthguards specifically for you. The custom fitting ensures you of better protection and a comfortable fit. Custom guards are also built in layers for durability. The American Dental Association recommends custom guards for orthodontic patients. Your mouthguard will be designed to provide proper protection for both your teeth and your braces.

No matter what type of sport you participate in, a mouthguard can protect your braces. Even an activity as seemingly harmless as table tennis can result in a contact injury. The Academy for Sports Dentistry states that a properly fitted mouthguard should not interfere with any athletic activity.

Lowder Orthodontics will provide you with properly-fitting mouth protection to ensure the safety of your braces and your teeth. We will be glad to answer any questions you have so you can continue the activities you enjoy with little concern. If you do suffer any injuries to your mouth or braces during sporting activities, please contact us immediately. The sooner we can care for your mouth, the better the results will be.

Taking care of your oral health involves a daily regimen of brushing, flossing, and rinsing to prevent tooth decay and bacterial infections. Though you may have asked us which toothbrush to use, few patients at Lowder Orthodontics ask about mouthwash.

However, different mouthwashes you might choose will have varying effects on your oral health. So which type is best for you?

Gum Health

Antiseptic mouthwashes are designed to reduce the majority of bacteria on and near the gum line. Using an antiseptic mouthwash can help decrease your chances of developing gingivitis. If possible, look for a mouthwash with antibacterial or antimicrobial ingredients.

Fluoride

Fluoride is beneficial for oral health and can help prevent tooth decay. If you drink a lot of bottled water without fluoride, we may recommend that you purchase a rinse with fluoride in it.

Bad Breath

Although mouthwash is designed to prevent bacterial build-up within the mouth, many people use it to combat bad breath. Most mouthwashes will help eliminate the bacteria that cause bad breath, and some are specifically designed to do so.

However, if bad breath is a chronic problem that requires daily treatment with a mouth rinse, contact Lowder Orthodontics to discuss your symptoms.

American Dental Association Approval

The ADA reviews mouth rinses for safety and effectiveness. A mouthwash with the ADA Seal of Approval will meet strict criteria, and will have scientific evidence or clinical studies that support the claims of the manufacturer. If possible, select a mouthwash that bears the ADA Seal of Approval to ensure you are using a quality rinse.

Considerations

If you are unsure as to which mouthwash is right for you, contact our Idaho Falls, Rigby, Rexburg, Afton, and Salmon office or ask Dr. Lowder during your next visit. Also, be sure to keep mouthwash out of the reach of children, as it contains alcohol and other substances that could be harmful to them. Avoid letting children under age six use a mouth rinse, and discontinue use if you experience a burning sensation in the soft tissues of your mouth.
