Whenever we bite down, we’re applying force with our jaw muscles. Functional appliances direct these forces to create healthier tooth and jaw alignment. They’re used to help correct bite problems and to encourage symmetrical jaw growth.

Functional appliances aren’t always necessary. Because every child’s teeth and bite are different, orthodontic treatment at our Tampa office is carefully tailored to your child’s individual needs.

• For the child with minor tooth misalignment, traditional braces or aligners might be all that’s needed.
• For the child with a minor malocclusion, or bite problem, an orthodontist might use elastics (rubber bands) to bring teeth into healthy alignment.
• For the child who has a more serious malocclusion, involving both tooth and jaw alignment, an orthodontist might recommend a functional appliance.

A severe Class II malocclusion can be caused when the upper jaw or teeth are positioned too far forward, and/or the lower jaw is too small or positioned too far back. Common Class II malocclusions include:

• Open bite—the front teeth don’t touch when the back teeth bite down, or the back teeth don’t touch when the front teeth close.
• Overbite—some overbite is normal. A deep overbite occurs when the upper teeth significantly overlap the lower teeth.
• Overjet—the upper front teeth protrude further horizontally than they should.

Today’s functional appliances come in a variety of designs to treat Class II malocclusions. They can be fixed or removable. They can be used with or without braces. Some are designed to expand the upper palate to make sure there’s room for all the permanent teeth. What they all do is advance the position of the lower teeth and jaw to create a healthier, more comfortable bite.

Fixed devices are attached to the teeth and meant to be used full-time. These include the Forsus™ device, the Herbst® appliance, and the MARA appliance.

• Forsus Device

This appliance works with braces. A spring coil rod is most often attached to bands on the first molars on the upper jaw. It’s then connected to the arch wire on the lower jaw. Just like elastics—but more effective!—these spring coil rods provide gentle forward pressure that encourages the lower jaw and teeth forward.  

• Herbst Appliance

The Herbst appliance also applies forward pressure to the lower jaw using telescoping rods connecting the upper and lower teeth. The rods expand as the mouth opens, and telescope together as it closes, positioning the lower jaw further forward while the upper jaw is held back. The Herbst can be worn alone or with braces, and can also be used to expand the upper palate.

• MARA Appliance

The MARA (Mandibular Anterior Repositioning Appliance) uses an adjustable “elbow” piece connecting bands on upper and lower molars to guide the lower jaw and teeth forward when the jaw closes.

Removable appliances such as Bionator and Twin Block appliances can also improve Class II malocclusions. They are meant to be worn for a specific number of hours each day, and can be taken out for sports or other activities as needed. Because it’s essential to get all the necessary hours in, removable appliances require commitment!

• Bionators

A bionator is made of wire and acrylic, and it looks a lot like a retainer. The wire fits around the upper front teeth. It’s attached to a smooth piece of acrylic that sits behind the upper teeth and is shaped to guide the lower jaw forward when biting down. The bionator can also be adjusted to expand the upper palate.

• Twin Block Appliance

The twin block appliance uses two separate pieces made of wire and smooth acrylic. Both pieces are modeled to fit precisely over the upper and lower arches. The acrylic “blocks” fit over the biting surfaces of the teeth, working together like a 3D puzzle. When your child bites down, the upper blocks slide into place behind the lower blocks, pushing the lower jaw and teeth forward. The top plate can also be adjusted to expand the upper palate if needed.

Because these appliances are best used while a child’s bones are still growing and developing, dentists and orthodontists recommend an orthodontic evaluation by age seven. Early treatment with a functional appliance can help correct serious bite problems before or together with braces. In some cases, functional appliances may reduce the need for headgear or surgery.

Todays’ orthodontic technology has made functional appliances more comfortable and efficient than ever before. Talk to Dr. Gregory Dyer to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

Dr. Gregory Dyer and our team recommend always wearing a protective mouthguard to participate in most physical sports. We especially encourage this if you have braces that can potentially cut your mouth or cause damage to your teeth. You have various choices to consider when you’re looking for a protective mouthguard.

One option is a full facial guard, which is often used for contact sports, such as football or hockey. This type offers full protection of the face from external impact. You should also consider an additional mouthguard to protect yourself from cuts inside your mouth, and avoid possible damage to your braces.

Boil-and-bites are another version of mouthguard that can be used for more physical sports. This type is used just the way its name implies: You warm the mouthguard in water to soften the material, then bite down gently once it’s at the correct temperature to form it into the shape of your mouth. These are fine to use temporarily, but they don’t always provide the best protection if they don’t fit properly.

Another option is to have Dr. Gregory Dyer make a custom mouthguard for you. The mouthguard will be designed with built-in layers to protect both your teeth and braces when it’s worn. Having Dr. Gregory Dyer create a custom-fitted mouthguard will ensure optimal protection and a comfortable fit whenever you participate in physical activities.

Protecting your teeth and braces is essential when you compete in sports. Accidents happen, and having a preventive mouthguard can potentially save you from oral pain and damaged braces. Our Tampa office is happy to assist you in creating a custom-made mouthguard for any sports activities you want to pursue.

If you’ve experienced a mouth injury that has caused damage to your braces, please contact us immediately so we can fix the problem right away. Remember, prevention is key when it comes to your oral health!

A solid oral health routine begins with daily brushing, flossing, and rinsing. Without a consistent oral health regimen, you may begin to experience tooth decay and bacterial infections. Few patients ask Dr. Gregory Dyer about different mouthwash options, so we’ve put together a list of the conditions that mouthwashes can treat. This should help you decide which oral rinse would be best for you.

Gum Health

Antiseptic mouthwashes reduce large amounts of bacteria on and near the gum line and generally help to decrease your chances of developing gingivitis. The key ingredients of antiseptic mouthwashes are antibacterial and antimicrobial items. Antiseptic mouthwash is a preferable option if you are concerned about the general gum health of your mouth.

Fluoride

Fluoride is a great tool for preventive tooth decay treatment. It prevents tooth decay and is great for oral health in general because it kills germs that can live in your mouth. Fluoride also builds stronger teeth. If you’re a bottled water drinker, Dr. Gregory Dyer may recommend that you purchase a simple fluoride rinse to use after brushing.

Bad Breath

Fluoride mouthwash can be used to fight any bad breath issues you may be facing. It’s designed to combat any bacteria that might be building up in your mouth. Most mouthwashes will help eliminate bad breath, but some are specifically designed to address this difficult problem. If you feel as though this might be turning into a chronic problem, please contact Dr. Gregory Dyer to discuss other options that would be effective for treating your symptoms.

American Dental Association (ADA Approval)

The ADA reviews all mouth rinses for safety measures and to prove effectiveness. Any mouthwash approved by the ADA has met strict guidelines according to whether the manufacturer’s claims are supported with scientific evidence. If you’re looking for a quality mouthwash, look for one that has the ADA seal of approval to ensure you have a great rinse for your mouth.

Considerations

When you’re trying to decide which mouthwash to pick, contact our Tampa or ask Dr. Gregory Dyer during your next appointment. If you experience a burning sensation in the soft tissues of your mouth, be sure to discontinue use immediately. Avoid letting children under age six use a mouth rinse, and be sure to keep all mouthwashes out of the reach of children, because they contain alcohol and other substances that could be harmful.

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. Gregory Dyer 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 Tampa orthodontic office, Dr. Gregory Dyer 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!
