Dental X-rays: The Inside Story

January 8th, 2025

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. Elizabeth Hite, DMD, MS 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 Edwardsville 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!

New Year's (Orthodontic) Resolutions

January 1st, 2025

Why are New Year’s resolutions so often negative? A depressing reminder of things-you-should-be-doing-but aren’t. A new set of rules-that-must-be-obeyed. A nagging list of changes you should make right this very . . .  

No! That’s no way to start the year! Let’s make your resolutions for the New Year a positive, proactive guide to help you achieve your goals for the next 12 months. And high on that list? Creating a beautiful, healthy smile.

If you are working with Dr. Elizabeth Hite, DMD, MS to improve the alignment of your teeth and bite, here are some easy, affirmative resolutions to make sure your treatment stays on track.

  • Be Healthy

Brushing is always important. That’s why we recommend brushing at least twice a day, at least two minutes each time. But when you wear braces or aligners, brushing regularly is even more important.

After every meal and every snack, food particles collect around brackets and wires. If you wear aligners, food particles on and between the teeth can end up trapped there.

No one wants more opportunities for cavities to develop, so follow our advice on brushing and flossing around your braces whenever you eat a meal or snack, and be sure to clean your teeth before replacing your aligners.

  • Be Thorough

Brushing carefully is important not just for preventing cavities, but for a brighter smile. And while you want a whiter smile, what you don’t want is white spots on your teeth. These discolored spots are caused by decalcification. What’s decalcification, you ask?

Bacteria and plaque stick to our teeth, and, when not brushed or flossed away, produce acids which eat away at minerals in our enamel. In places where minerals such as calcium and phosphorus leach out of the enamel, a white spot on the tooth appears. Left untreated, these weakened areas can develop into cavities.

Avoid having to deal with this discoloration when your braces or aligners are removed by careful brushing and regular professional cleaning.

  • Be Safe

If you play sports or live an active life, you might already be using a mouthguard. Good for you! Mouthguards have prevented countless injuries. Now that you have braces, talk to Dr. Elizabeth Hite, DMD, MS about whether a custom mouthguard is a good idea.

  • Be Responsible

If you have braces, brackets and wires can come loose. You can reduce the chances of that happening by following our instructions on what and what not to eat, and by brushing thoroughly-but-gently with a soft-bristled toothbrush.

If you have aligners, follow the manufacturer’s instructions for caring for them. Exposing them to heat, or eating with your aligners in, or not keeping them in their case when you’re not wearing them, can cause warping or breakage.

If you have a retainer, always make sure it’s in its case when it’s not in your mouth.

  • Be Adaptable

When you visit our Edwardsville office, ask us about better brushing tools and techniques, so once your braces or aligners come off, you’ll have a bright, beautiful, healthy smile as the reward for all your hard work.

  • Be Finished!

Dr. Elizabeth Hite, DMD, MS will give you precise instructions on when and how long to wear your bands or your aligners. Failing to put in the hours now means that you will have to spend more time in treatment later. And, of course, make sure you keep all your orthodontic appointments.

Resolving to follow our advice can bring you a healthier, happier smile before you know it. Positive goals lead to positive results, so let this be the year that your proactive resolutions lead to a lifetime of beautiful smiles.

What's the best dental floss?

December 25th, 2024

Dental floss is similar to a lot of products that depend mainly on the consumer’s preference. Fact is, floss comes in a wide variety of flavors, coatings, and other variations, but all types of floss essentially do the same thing. After all, that is what is most important: that the dental floss you buy is functional—cleaning the areas in between your teeth. If you want to know what the best dental floss is, the answer is the kind that enables you to successfully and regularly clean those areas. So to help you find the right type of floss for you, here are some options.

Flavored Dental Floss

Many people that floss prefer a flavored dental floss because it freshens their breath even more than unscented floss. The latter can also take on the smells associated with bacteria in your mouth. And we all know how bad that can be. So, if flavored dental floss is what you prefer, and it allows you to floss your teeth regularly, then it is automatically best for your mouth.

Flossers

There are also products on the market called flossers, which usually consist of a plastic instrument with strung floss and a pick on the opposite end. This option can be both effective at cleaning the areas in between your teeth and scraping off plaque. These flossers also come flavored in mint and various other varieties.

Gentle Dental Floss

Some people find that typical dental floss is too harsh on their gums. For that reason some companies make floss with soft coatings that are less abrasive on the gums. For the most part these types of floss are just as effective as regular floss, and for those people that require a more sensitive approach to flossing, especially when just starting out, this is the best option.

Of the aforementioned options, it is difficult to name an absolute best type of floss. However, Dr. Elizabeth Hite, DMD, MS and our team say that the type of floss that works best for you, giving you the greatest chance of succeeding at regular flossing, is the best. For more information on floss, contact our Edwardsville office.

Post-Braces Care: Wear your retainer!

December 18th, 2024

Many patients underestimate the importance of wearing their retainers after their braces come off, but it is one of the most critical post care practices to keep your teeth in alignment. Why spend all that time, energy, and money to straighten your teeth when you don't plan to keep them straightened after treatment?

What is a retainer?

As the name implies, a retainer keeps teeth from moving back to the positions in which they started before treatment was administered; they "retain" your smile and bite. There are many different types of retainers—some are removable and some are permanent. Some retainers are made of plastic and metal (known as Hawley retainers) and others are all plastic or all metal. Some retainers can even be bonded to the back of your teeth!

How long do I need to wear it?

If you've been given a removable retainer by Dr. Elizabeth Hite, DMD, MS, you may be wondering how long you need to wear it. It takes time for the tissues and bones around your teeth to reorganize and set into place after braces treatment.

The amount of time you’ll need to wear your retainer depends on your unique situation, but typically, retainers should be worn at least as long as the time you spent in braces. You might need to wear them full-time for a while, and then transition to wearing them only at night. Dr. Elizabeth Hite, DMD, MS will have a treatment plan especially for you, and if you stick to it, you'll always have a straight smile.

Nothing is forever (at least without retainers!)

Research has shown that there is no “permanent” position for your teeth to remain in. In fact, some studies say upward of 70% of patients will see a change to their bite and tooth alignment as they get older. This applies to people who have had orthodontic treatment and those who have not. Of course, some people's teeth never seem to shift—you can consider them the lucky ones, as most people's teeth do.

And this is precisely where retainers come in. The only way to ensure your teeth stay in alignment long-term is by wearing your retainers. If you have any questions about retainers or your treatment plan, please ask any member of our Edwardsville staff.
