Dental X-rays: The Inside Story

April 29th, 2020

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. Dennis Johnson 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 Columbus, OH 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!

Snacks that are Healthy for Your Body and Your Braces

April 22nd, 2020

You know the school day’s over when you hear these seven little words: “I’m home! Is there anything to eat?”

And before your child got braces, you had the answer: simple, tasty snacks that provided not only an energy boost, but nutritional elements to help build strong teeth and strong bodies. But now whole carrot sticks and unsliced apples are out. Nuts and crunchy peanut butter? Not in your pantry. Hard cheeses and crunchy whole grain crackers? Also off the shopping list.

Because any foods that are crunchy, chewy, or hard to bite into can damage brackets and wires, it’s time to freshen up your go-to snack list. Luckily, Dr. Dennis Johnson can recommend many healthy and braces-friendly choices when children need something to tide them over until dinner.

  • Fruits and Vegetables for Vitamins and Minerals

Soft fruits like berries, melon, and bananas provide essential vitamins and minerals while going easy on your child’s braces. Make it a blended smoothie for a cool treat—you can even add a healthy handful of spinach or kale without interfering with that fruity taste. If your child still loves apples and carrots best, keep them on hand—but remember that thin slices are the only way to go.

  • Dairy Delivers Calcium

Cottage cheese, string cheese, and other soft cheeses provide essential calcium and vitamin D. Yogurt in all its many flavors is another great option.

  • Meats Provides Protein

Lean meats such as thinly sliced ham, chicken, or turkey provide flavor and protein, and don’t require the chewing that bologna, roast beef, and salami do. And nothing packs a protein punch like eggs—hard boiled, deviled, or diced up in egg salad.

  • Grains, Legumes, and Vegetables for Complex Carbohydrates

Complex carbohydrates—the “good” carbs—are important sources of energy for our bodies. Snacks such as hummus with soft whole grain pita wedges or blended black bean dip and soft crackers are a delicious, energizing option.

You are constantly looking for ways to make your children’s lives better. Mix and match any of these foods for a snack that’s not only good for their braces, but good for their teeth and bodies! Let us know your child’s favorite snack the next time you visit our Columbus, OH office!

Ceramic Braces

April 15th, 2020

Congratulations! You have made the decision to get orthodontic treatment at our Columbus, OH office. Now it’s time to choose among your various appliance options. Traditional metal brackets and wires, lingual braces, a series of aligners—they all have positives to recommend them. And for some people, ceramic braces are the clear favorite.

Ceramic braces work like regular metal braces. Brackets are bonded to the front of each tooth, and rubber bands surrounding the brackets hold the arch wire that gradually moves the teeth into alignment.

Ceramic braces, however, use brackets made of clear or tooth-colored ceramic or porcelain which blend beautifully with the color of your tooth. The elastic ligatures, or rubber bands, can be chosen to match the brackets or your enamel. There are self-ligating ceramic brackets which don’t use bands at all. Technology is even working on ways to make the arch wire less visible! The end result is braces that are almost undetectable.

If you want a less obvious appliance for professional or personal reasons, talk to us about ceramic braces. As always, there are other factors to consider before you decide, which we will be happy to discuss with you.

  • Ceramic brackets are very strong, but they are still more brittle than the metal model. If you play a contact sport, these might not be for you. (But whatever braces you choose, please wear a mouthguard when playing sports.)
  • Ceramic braces might not be ideal depending on the amount of alignment and bite correction that is needed. They might also take a bit more time to bring your teeth into alignment. We will be able to tell you if ceramic braces will work for you and if they might require a longer period to move your teeth to their perfect position.
  • Brackets can sometimes be somewhat larger (though this isn’t always the case), and, because they can be abrasive, are often recommended for upper teeth only. This way, the lower teeth will not impact, or be impacted by, contact with the upper teeth.
  • Oral hygiene can trickier with ceramic braces. Although today’s brackets aren’t as prone to staining, you still need to be careful to brush away the plaque that can accumulate around the brackets. And the bands are susceptible to staining by the usual suspects—coffee, tea, colas, blueberries, or any strongly colored food or beverage.
  • Costs will differ depending on the treatment method you choose. Talk to us about cost comparisons with other orthodontic treatments.

Ceramic braces, because they are so much less visible, are a popular orthodontic option, especially for older teenagers and adults. If you are interested, talk to Dr. Dennis Johnson about this effective way to straighten your teeth—discreetly. Ceramic might be the clear solution for creating your lasting, beautiful smile.

Awesome Archwires

April 8th, 2020

When we think braces, we can’t help but think of the brackets on each tooth and the colorful ligature bands that surround them. But actually, the whole point of those brackets and bands is to hold the archwire in place as it gradually moves your teeth to create a better bite and a straighter smile. Let’s learn more about this talented part of your braces!

  • Wire We Wearing These, Anyway?

Archwires use gentle, continuous pressure to move your teeth into alignment. That sounds simple, but there is actually a lot going on. Teeth often need more than realigning. Some teeth need to be turned a bit, some tilted. Your teeth need to be better aligned with those next to them, of course, but also need to fit properly with the teeth above or below them. You might have a malocclusion, or bad bite.

How can one wire handle all that? Well, it can’t. That’s why there are different types of wire. We often use thinner, flexible wires at the beginning of treatment, to put gentle pressure on the teeth as they start their movement. Other wires are firmer, and can be helpful in later phases, when each tooth is carefully moved to its specific, ideal spot. Archwires can be round or rectangular, thicker or thinner, springy or stiff, remember their shape or be bendable—all depending on what they need to do.

Whew! This sounds confusing, but Dr. Dennis Johnson and our team are archwire experts! At every adjustment appointment, we check on the progress of your alignment and choose the exact wire you need to take you to the next stage of your orthodontic journey.

  • Out of the Frying Pan, Into the Wire

Now that you have braces, it’s more challenging to make sure that your teeth are clean after eating. We’ll give you advice on how to get rid of the pesky food particles that sometimes get stuck in your braces. First, that’s absolutely not the look you’re going for. But, more than that, bacteria can use these “leftovers” as fuel to create the acids that damage your enamel and cause cavities.

There’s a whole new world of dental products out there waiting to help get your braces clean. Special toothbrush heads work in the spaces between your teeth and the archwire. There are floss threaders that can get dental floss into tight places, and flosses with one stiff end you can guide under the wire so you can direct the floss to where it’s needed. There are even tiny cone-shaped brushes called “interproximal brushes” that can fit under your wires to clean around your brackets and teeth.

Take a care kit to school or work with you so you can keep the tooth surface under your wires and around your brackets free of plaque. After all the hard work you’ve put in with your braces, the last thing you want is cavities once you’ve achieved your beautiful smile!

  • Down to the Wire

We said archwires were awesome, but we didn’t say they were perfect! We couldn’t leave without suggestions for handling any wire-related problems that might come up.

One of the most common problems is the irritation caused by the end of a wire that has somehow come loose. You might be able to use a cotton swab to gently push the wire flat against the tooth. If that doesn’t work, orthodontic wax can be used to cover the end of the problem wire and smoothed into place. We’ll provide you with instructions on how to handle these and other minor wire problems at home. 

Other problems should be run past us first. If you feel your wire is coming loose, or if a loose end is causing a lot of pain and irritation, call our Columbus, OH office. We’ll give you instructions on how to help, and make an appointment if necessary for a professional fix.

In fact, call us anytime you have questions about your braces. We’re here to help you understand each phase of the orthodontic process as you move step by step on the path to a healthy bite and a beautiful smile. And what’s more awesome than that?
