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. Byron Diehl 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 Redlands, CA orthodontic office, Dr. Byron Diehl 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!

Congratulations! You’ve done the hard work necessary to create your beautiful smile! You’ve carefully completed all the steps needed to reach the end of your orthodontic journey. Well, nearly all the steps. We can’t forget that last step which will ensure that all your hard work is rewarded.

When you first began orthodontic treatment, Dr. Byron Diehl decided on the best plan for straightening your teeth and perfecting your bite, whether you wore traditional braces, lingual braces, aligners, or other orthodontic appliances. And now that you’re finishing treatment, there’s one more option to consider—your retainer.

Why do I need a retainer?

While you’ve spent time in treatment, more has changed than just the position of your teeth. The periodontal ligament, the connective tissue that connects the teeth to the jawbone, is stretched as the teeth shift. The bone in your jaw changes, too, reforming and rebuilding around the roots of your teeth as they move to their ideal locations.

These changes happen because your braces or aligners apply gentle, constant pressure to move your teeth. When you’ve finished wearing these appliances, the pressure stops. Ligaments will try to return to their original shape, which can shift teeth back toward their old positions. And the rebuilding bone isn’t dense enough yet to stop teeth from shifting due to the normal, everyday pressures of eating, chewing, and smiling.

A retainer prevents your teeth from moving back, or “relapsing,” by giving your bones and ligaments time to stabilize and rebuild. The process takes months, so keeping your teeth in place as bones rebuild and grow denser is crucial. This is especially important for patients with more serious misalignments. Dr. Byron Diehl will let you know which kind of retainer will be best for you and just how long you’ll need to wear your retainer.

Are there different kinds of retainers?

There are! Retainers can be removable or fixed, visible or nearly invisible, metal, plastic, or metal and plastic. Three of the most popular retainer options include:

• Hawley Retainers—the traditional removable retainer, which uses a molded acrylic plate with wires attached to keep your teeth properly aligned and to hold your retainer in place.
• Clear Plastic Retainers—a removable retainer made of custom vacuum-formed plastic, which fits over the teeth like a clear aligner.
• Fixed Retainers—a small single wire bonded to the back of specific teeth, which holds them in place and prevents any movement.

Dr. Byron Diehl will let you know whether a removable or fixed retainer is best for making sure your teeth don’t start to relapse, and fill you in on the benefits and care of each type of retainer.

How long do I need to wear a retainer?

There’s no standard answer to this question. Just like your retainer is custom-built to fit your individual teeth, the amount of time you’ll spend in that retainer depends on your individual needs. Retainers might be worn fulltime for months or years, be worn only at night after several months of daily wear, or be worn long-term to make sure your orthodontic work lasts.

Because you’ve done the hard work already, and your beautiful, healthy smile is the result. Talk to a member of our Redlands, CA team about which retainer option will be best for making sure that this smile lasts a lifetime.

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. Byron Diehl 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 Redlands, CA team about making that smile a reality.

The weather out there might be frightful for most of us, but not for you! You’ve been waiting all year for a fresh coat of powder and all the outdoor sporting activities winter brings. But before you grab those ski poles, strap into that snowboard, lace up those skates, or dust off that sled, be sure to remember one more essential piece of gear—your mouthguard!

Mouthguards aren’t just for contact sports. While all that lovely new snow looks like powder, it doesn’t feel like it when you land hard. If there’s a chance of a fall or an impact in any sport, there’s a chance you can suffer dental injuries.

Falls or collisions can result in chipped, broken, or dislodged teeth. Your mouthguard will help protect your smile from these accidents, and also works to protect you from biting your tongue and mouth in case of impact. It can even reduce the chance of jaw injuries.

Luckily, finding a mouthguard that works for you is even easier than finding the perfect board or the best wax for your skis. You have several options to choose from:

• Ready-made appliances. These are available in drugstores and sporting goods stores, but come in pre-formed sizes, so they might not provide the best fit.
• The “boil-and-bite” model. This mouthguard form is placed in hot water. You then bite down while it is pliable to shape it to your mouth and teeth.
• Custom mouthguards. These guards can be fabricated just for you. They are molded to fit your individual mouth and teeth, so provide a better fit and better protection. They are also usually more durable and more comfortable. If you wear braces, a custom mouthguard can be your best option for preventing an injury to your mouth and your braces. Talk to Dr. Byron Diehl if you are interested in a guard fitted specifically for you.

When you visit our Redlands, CA office, let’s discuss all the best ways to keep your teeth and mouth protected before you set out for winter sports. And then when you’re ready to go? Let it snow!
