These days it's becoming more and more common to see adults at our Chicago, IL office getting their teeth straightened with Invisalign clear aligners — that is, if you can see them! Treatment with Invisalign is effective and aesthetically pleasing for all ages, but adults have certainly taken to them.

For some it may be to overcome the stigma that "braces are just for kids," but for others it may be the displeasing appearance and discomfort of traditional braces. According to the American Association of Orthodontics, from 1994 to 2010 the number of adults 18 and older getting braces increased by 58 percent, from 680,000 to 1.1 million annually. Many of these adults opt for Invisalign because of how discreet they are and since they don't need to avoid any foods or make dietary changes like you do with traditional braces.

The benefits of getting your teeth into proper alignment are many, and so are the advantages of Invisalign. By following your individual course of Invisalign treatment, you can expect to enjoy the following benefits over traditional braces:

• The total treatment time is more precise with Invisalign since your treatment is modeled by a computer, as compared to traditional braces where it is really just an estimate.
• You'll need to make fewer trips to our Chicago, IL office since you can change your trays on your own every few weeks or as prescribed.
• There's less risk to the health of your tooth enamel since there is no need to place brackets on your teeth.
• Invisalign aligners are clear and practically invisible, so most people won't even know you're wearing them!

If you're interested in Invisalign treatment, please let Dr. Karen Seder know. We'd be happy to help you on your journey to a straighter, healthier smile!

The Valentine shopping list is traditional and simple: Flowers. Candy. But if your Valentine is in braces this year, suddenly your choices become more complicated. No need to worry! Dr. Karen Seder and our Chicago, IL team have some sweet suggestions that are both braces-friendly and Valentine-approved.

First, let’s look at some options where Cupid’s arrow has missed the mark.

• Caramels—these sticky treats are difficult to clean from orthodontic work, and sticky, chewy foods can even cause damage to wires and brackets.
• Chocolate covered nuts—hard foods such as nuts can break or bend wires and brackets.
• Assorted chocolates—a confectionary minefield! There are bound to be some caramels and nuts in there somewhere, hiding beneath an innocent coat of chocolate, just waiting to ruin your Valentine’s evening.
• Other candies such as taffy, licorice, hard candy? No, no, and no. Remember, anything sticky, chewy, or hard is on the “Loves Me Not” list.

So, which chocolate treats won’t break hearts or braces?

• Soft truffles—if it’s not Valentine’s Day without a be-ribboned box of chocolates, choose soft truffles to fill it.
• Chocolate mousse—the perfect end to a romantic dinner.
• Chocolate covered strawberries—it’s a special occasion treat that won’t mistreat braces.
• Rich chocolate cake—always a delightful indulgence, and even better if it’s in the shape of a heart.

If your Valentine is not a chocolate fan, there are other sweet treats that are delicious alternatives.

• Cheesecake can be topped with (pitted!) cherries to celebrate in holiday-appropriate color.
• Soft heart-shaped cookies will be even more romantic with decorative icing—add your initials for a personal touch.
• Select an array of frozen yogurt, ice cream, or gelato in different shades of pink.
• Macarons also come in a variety of pink and red shades—but make sure this confection is on your Valentine’s braces-friendly list!

Of course, you can celebrate the day without sugary tributes. A single flower, watching your favorite movie together or, best of all, a heartfelt card or letter are all wonderful ways to show you care. But if it’s just not the same holiday without a sweet treat, try some of our suggestions. Your Valentine will appreciate your thoughtfulness.

Teeth erupt crookedly for a number of reasons that range from genetics to mouth deformities and serious oral diseases. When extra teeth or abnormally large teeth create a malocclusion (crookedness or misplacement of teeth), the culprit is usually genetic in nature. Other inherited traits involve jaws that are too small to accommodate a full set of teeth and misaligned jaws that did not form properly in the womb.

Can crooked teeth be prevented?

In most cases, underbites, overbites, and crooked teeth are genetically derived and can’t be avoided. Orthodontic treatment with braces will be necessary to correct the condition once the child is old enough to wear them. However, certain early childhood behaviors may also contribute to the development of crooked teeth that can be avoided. These include:

• Thumb sucking and tongue thrusting
• Losing baby teeth to decay before permanent teeth have naturally pushed them out of their sockets
• Allowing pacifier use to continue after front teeth have erupted

Permanent teeth underneath baby teeth are directly affected by the health of baby teeth. If baby teeth are prematurely lost due to decay or trauma, permanent teeth will shift when they start moving upward. Baby teeth are like anchors for permanent teeth that help guide them as they erupt through the gums.

In addition, excellent care of baby teeth is vital to having healthy permanent teeth free of discoloration or decay. Harmful oral bacteria can spread into the gums and reach permanent teeth still buried in the gums. Once attached to a tooth’s enamel, bacteria will begin eroding the tooth even before it has a chance to take its first bite!

When to Start Orthodontic Treatment for Crooked Teeth

Dr. Karen Seder and our staff suggest that parents bring your child to Seder Orthodontics around age seven to rule out potential issues with permanent teeth eruption. If problems are discovered, it is not unusual to begin orthodontic treatment at that age. In fact, specific conditions such as crowding and gaps between teeth are easier to correct at an early age.

Early treatment also benefits from the growth process of the jaw, which helps move teeth to normal positions.

We’re all friends here, so if you sometimes feel a bit nervous before your orthodontic appointments, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and your orthodontic options so you know exactly what is going on during treatment. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes patients feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is called radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs. 

There are many different types of dental X-rays used in orthodontics, including:

• Occlusal X-rays, which show the entire arch of teeth in the upper or lower jaw.
• Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
• Cephalometric X-rays, which show the patient’s entire profile, and the position and development of the teeth and jaws.
• Cone Beam Computed Tomography, an external device which uses digital images to create a three-dimensional picture of the teeth and jaws.

Why Do We Need X-rays?

You might have noticed that these X-rays, unlike, for example, typical bitewing X-rays, don’t take images of individual teeth. That is because orthodontists deal with the teeth in relationship to each other and to the structures around them.

Beautifully aligned teeth and a healthy bite are the visible result of your orthodontic work, but there’s a lot going on above and below the surface that needs to be discovered and taken into account before your treatment even begins. X-rays help us evaluate:

• The size, shape, and position of your teeth, including impacted teeth and wisdom teeth
• The size, position, and health of your roots throughout treatment
• The size and shape of your jaw bones, and how they affect your teeth alignment and bite
• Your progress during different phases of treatment

How Do Orthodontists Make Sure Your X-rays Are As Safe As They Can Be?

First of all, the amount of radiation you are exposed to with a dental X-ray is very small. In fact, a typical panoramic X-ray provides roughly the same amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Karen Seder and our team are committed to making sure patients are exposed to as little radiation as possible.

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:

• We take X-rays only when they are necessary.
• We provide protective gear, such as apron shields and thyroid collars, whenever needed.
• We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
• When treating children, we set exposure times based on each child’s size and age.

And now that we’ve talked about some things you might like to know,

Please Let Us Know If . . .

• You are changing orthodontists and have had previous orthodontic X-rays taken. Ask to have your older X-rays sent to our office so we have a complete record of your orthodontic history. (With digital X-ray technology, this transfer can be accomplished with e-mail!)
• You’re pregnant, or think you might be pregnant. Even though radiation exposure is very low with dental radiographs, unless there is a dental emergency, dentists and doctors recommend against X-rays for pregnant patients.

X-rays play an important part in helping us make sure your orthodontic treatment provides you with a lifetime of beautiful and healthy smiles. If you have any concerns, contact our Chicago, IL office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!
