An overbite is one of the most common malocclusions. If Dr. Joseph Brogan and our team have diagnosed you with an overbite, you probably have lots of questions. Let’s try to answer some of them!

Just what is an “overbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. A normal overlap is generally considered one or two millimeters.

An overbite is a Class II malocclusion, and means that the upper front teeth cover more of the lower teeth than they should. But that’s a very general definition, and we will diagnose and treat your own, very specific, bite and teeth alignment.

Because overbites aren’t all alike. They might be barely noticeable. Upper teeth might overlap lowers by an extra millimeter or two. In more severe overbites, the upper teeth might cover the lower teeth completely. The amount of overlap and the cause of the overbite will determine your treatment.

What causes an overbite?

Overbites can be dental, caused by tooth alignment, or skeletal, caused by bone development, or a combination of both. They are usually hereditary, so, most often, an overbite is something you’re born with.

The size and position of your jaws, the shape and position of your teeth, all affect your bite alignment. But early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use can contribute to overbite development. Missing teeth and bruxism, or tooth grinding, can also affect the alignment of your bite.

How do we treat an overbite?

There are many types of treatment available. Dr. Joseph Brogan will recommend a treatment plan based on the type and severity of your overbite. Because some treatments are effective while bones are still growing, your age plays a part as well.

• Braces and Aligners

If dental issues are the main reason for your overbite, braces or clear aligners can be very effective. Rubber bands are commonly used to help bring teeth and jaw into alignment.

• Functional Appliances

If the overbite is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still forming.

For young patients, there are several appliances that can help correct an overbite. Some, like the Herbst appliance, work inside the mouth, while others, like headgear, are worn externally. Your orthodontist will recommend the most effective appliance for your needs.

• Surgical treatment

In some cases, where the problem is skeletal rather than dental, surgical treatment might be necessary to reshape the jawbone itself. This is especially true for adults, whose bones have finished forming.

If we recommend surgery, oral and maxillofacial surgeons are experts in surgical procedures designed to create a healthy and symmetrical jaw alignment. Dr. Joseph Brogan will work with your surgeon to design a treatment plan, which will usually include braces or other appliances following surgery.

Why treat your overbite?

Sometimes, a very slight overbite won’t require treatment. A serious, moderate, or even mild overbite, though, can lead to many dental and medical problems, including:

• Crooked, crowded teeth
• Worn teeth and enamel
• Problems speaking or chewing
• Difficulty sleeping
• Headaches, facial, and temporomandibular (jaw) joint pain

When you work with our Philadelphia, PA team to correct your overbite, you’ll not only prevent these unpleasant consequences, but you’ll achieve major benefits as well—a healthy, comfortable bite, and an attractive, confident smile. If you’d like more than an overbite overview, Dr. Joseph Brogan can provide the specific information and treatment plan you need to make that healthy bite and that confident smile a reality!  

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. Joseph Brogan 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 Philadelphia, PA orthodontic office, Dr. Joseph Brogan 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!

Maybe you’ve wanted braces since childhood. Maybe you had them, but your teeth have shifted over time. Maybe you’re tired of living with an uncomfortable bite. Good news! If you’re not happy with your adult smile, that doesn’t mean you’ve missed the opportunity to have the healthy, attractive smile you’ve always dreamed of.

While there are many benefits to having orthodontic work done as a child, there’s a lot to be said for orthodontic treatment as an adult. After all, you know exactly what you want. You’re dedicated to following your treatment plan. You have plenty of discreet orthodontic options available now, from clear aligners to lingual braces, to make your treatment as inconspicuous as possible.

But, on occasion, adult treatment does come with some adult baggage. Worried about your crowns, fillings, or veneers? If these restorations are part of your dental history, we can generally work with them. Dental implants? Those might fall into a slightly different category.

Implants are a great way to restore your smile because they function like your natural teeth. They are designed to look just like natural teeth, and they allow you to speak, chew, and bite with confidence. Implants even stimulate the jawbone when we chew just as natural teeth do, helping to prevent bone loss in the jaw as we age.

But there is one important difference between implants and natural teeth: implants are firmly anchored in the jaw, while your natural teeth can change position.

Why is this a concern? Because tooth movement is one of the basics of orthodontic treatment. Unlike implants, our teeth aren’t firmly anchored in our jaws. They are held in their sockets by a ligament which cushions them and connects the tooth to the bone.

When braces or aligners gently apply consistent pressure to the teeth, the ligaments and eventually the bones holding the teeth reshape themselves in response to this pressure, and then become stable again during the retainer phase of treatment.

Implants, on the other hand, are crowns attached to a metal cylinder or screw that is surgically implanted into the jawbone. After several months, osseointegration takes place—which is a technical way of saying that the metal base fuses with the bone. This means that there won’t be any movement taking place—good when you’re chewing, but not helpful for realignment!

If you haven’t yet replaced a missing tooth with an implant, it’s often best to wait before starting orthodontic work. We can design treatment around a missing tooth, leaving room to accommodate an implant in just the right spot when your orthodontic treatment is finished.

If you have an implant already, the placement of your implant will help determine your treatment:

• If your implant is already perfectly placed for your future alignment, braces or aligners can be designed to work with and around your implant.
• If the placement is almost ideal, you might find a very small degree of misalignment acceptable, and we can plan your treatment around your existing implant.
• If it’s not possible to work with your implant where it’s presently located, it is possible to remove an implant. You would then have the implant procedure redone after your orthodontic work is complete.

Talk to Dr. Joseph Brogan about your treatment possibilities. By analyzing your orthodontic goals and working with your dental history, we can let you know exactly what can be done for your teeth and bite—even if you have an implant.

True, there are many benefits to having orthodontic work done in your childhood, but there’s a lot to be said for orthodontic treatment as an adult. And the greatest benefit of all? You’ll finally have the healthy, self-confident smile you’ve always dreamed of. Talk to our Philadelphia, PA team about making that smile a reality.

Even though it’s called a “permanent retainer,” your fixed retainer isn’t necessarily meant to last a lifetime. But with care, it should last just as long as you need it, keeping your teeth perfectly aligned after your orthodontic treatment is complete. Why is this retainer the one to choose for challenging alignments?

A fixed retainer is often used for teeth which were very crowded or had large gaps before treatment, especially along the bottom teeth, which tend to shift more. With a permanent retainer, a custom fitted wire is attached with a bonding adhesive to the back of each of the selected teeth. This design makes sure that the teeth can’t shift out of place while your bones and ligaments strengthen around them.

Occasionally, though, your permanent retainer isn’t quite as permanent as it should be. If you think your fixed retainer is becoming “unfixed,” what clues should you look for?

• Broken wire

A clearly broken wire can be obvious, or you might discover it when you notice pain or irritation caused by the end of a wire poking around your tongue or mouth.

• Loose bond

The orthodontic adhesive used to bond the wire to each tooth can come loose as the result of an accident, an unfortunately chewy treat, or simply with the passage of time.

• Shifting teeth

You might not notice anything wrong with your retainer, but what you do notice is that your once-straight teeth have started shifting back to their old positions. If you see any movement in your teeth, your retainer might need repair.

What should you do?

• Give our Philadelphia, PA orthodontic office a call! It’s important to act promptly to prevent further retainer damage, oral discomfort, and tooth misalignment.
• Rinse with warm water if your mouth is irritated.
• If a wire is poking you, call us for advice on gently pushing it back into place.
• Orthodontic wax can protect your teeth and tissue from detached wires.
• If you have a clear retainer, wear it until you can come in. If you don’t have one, and you can’t see us immediately, ask if an over the counter moldable retainer is a good idea to help keep your teeth aligned in the meantime.

One benefit of a fixed retainer is that it’s almost invisible because it’s behind your teeth. But this hidden location can also make it difficult to notice potential problems. Fortunately, there are some proactive steps you can take to help your permanent retainer—and your bite—stay healthy:

• Avoid foods which are sticky, hard, or chewy. If a food can damage traditional braces, it can damage your retainer.
• Wear protective gear like mouthguards and helmets when you’re active—they protect more than just your retainer!
• Ask your dentist to examine your retainer adhesive’s staying power whenever you have a checkup.

If you notice a detached wire or loose adhesive or see your teeth shifting, give Dr. Joseph Brogan a call. It’s important to act promptly to fix a fixed retainer, because your teeth and bite alignment are in jeopardy when you delay. And always bring your retainer (or retainer pieces) with you in case we can repair it.

Permanent retainers don’t necessarily last forever. But whether your fixed retainer is going to be with you long-term, or whether you’re going to transition to a removable retainer in the future, let’s make sure your permanent retainer is just as “permanent” as it needs to be!
