Dental X-rays: The Inside Story

May 26th, 2021

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. Todd Hamilton and Dr. Bryan Whitecotton 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 Denver, NC 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!

When It Come to Chewing Gum, Be Choosy!

May 19th, 2021

Why do you chew gum? Perhaps because it’s a habit that comes with some healthy benefits. Chewing a stick or two reduces the urge to snack between meals. It’s a substitute for behaviors like nail biting that you’d like to change. It might even give you fresher breath after those tuna sandwiches in the cafeteria.

And, as it happens, chewing sugarless gum actually offers a few dental benefits as well! The act of chewing increases saliva production. Saliva washes away food particles, neutralizes acids in the mouth that can damage enamel, and even bathes the teeth in essential minerals that help strengthen weakened enamel. We’re talking about sugar-free gum here, of course, because regular gum will just bathe your teeth in sugar—no one’s idea of a dental benefit!

So why not open that pack and enjoy? Because, despite the many positive reasons you can think of for chewing gum, sometimes gum can have a negative impact on your braces.

  • A Sticky Situation

Keeping your braces clean can be a bit of a challenge. That’s why you have special toothbrushes, flosses, and interproximal brushes to get rid of food particles that stick around after you eat. And, while any food can get caught in your braces, sugared gum, because it is so sticky, can stick to appliances much more easily and much more thoroughly than even sugar-free gum. You might be able to remove gum residue with regular brushing and flossing, but, worst case scenario, you might be looking at gum firmly stuck in the brackets or between the brackets and wires.

  • Gumming Up the Works

Chewing gum can also affect your treatment time if the action of chewing causes your arch wire to bend. When your wire isn’t providing the proper shape or the right amount of tension, your teeth won’t get to where they need to be as quickly and efficiently. No piece of gum is worth discovering at your next appointment that you haven’t made any progress for weeks due to a damaged wire. And since chewing gum can also lead to loose brackets and bands, you might wonder if this sticky habit is ever worth the trouble it can cause.

  • Something to Chew Over

Before you decide, talk to Dr. Todd Hamilton and Dr. Bryan Whitecotton! Chewing sugarless gum increases saliva production, which can help wash away food particles from your mouth and your braces. As an added benefit, the action of chewing for a few minutes after an appointment has been shown to reduce the discomfort of an adjustment. Because today’s braces are stronger and more durable, and sugarless gum much less likely to stick to them, we can let you know if chewing gum might be acceptable or even desirable depending on your specific treatment plan and your appliance.

Talk to us at your next appointment at our Denver, NC office about gum chewing, and we’ll give you the very best recommendations for keeping your teeth healthy, your braces clean, your appliance intact, and your treatment plan on track. Even if gum needs to be off the menu for a while, what you’ll get in return—the best and fastest path to your beautiful smile—will be well worth it!

Invisalign® Q&A

May 12th, 2021

It’s estimated that up to four million people at any one time are wearing braces in the United States and Canada. But Dr. Todd Hamilton and Dr. Bryan Whitecotton and our team at Hamilton and Whitecotton Orthodontics know that braces have come a long way from the early days of orthodontics, so much so that these days, options are available that are not visible to onlookers. The most popular of these “invisible” braces is Invisalign. Here’s a list of FAQs regarding Invisalign:

Are they really invisible?

Yes, the clear liners are virtually invisible, so they enable patients to feel good about themselves and their appearance, while getting the orthodontic treatment they need.

Are there wires, rubber bands, and brackets with Invisalign?

Nope. Invisalign is truly an alternative to conventional braces. The treatment consists of clear liners that can easily be removed and cleaned throughout the day. There are no wires, so there’s less poking and mouth irritation compared to braces. There’s also no wire tightening at adjustment appointments, so patients don’t have to worry about a sore mouth in the days that follow in-office visits.

I’ve heard that if I get braces, I won’t be able to eat certain foods like popcorn and hard candy. Is this true with Invisalign too?

No. With Invisalign, there are no food restrictions. You simply remove your aligners when you’re eating, and replace them after you’ve finished and brushed any leftover food particles away.

Does Invisalign cost more than braces?

While overall cost varies on a patient-by-patient basis and is based largely on the level of treatment, Invisalign costs about the same as traditional braces, which makes this treatment option a truly affordable alternative.

How does brushing compare with conventional braces?

Brushing your teeth while wearing conventional braces takes some getting used to. Patients have to brush around the metal brackets and floss with a specialty tool to get into the hard-to-reach areas of the mouth. By contrast, Invisalign can be removed at any time to permit regular brushing and flossing.

Every patient is different and Invisalign might not be the best course of orthodontic treatment for everyone, but it's an option that's gaining more and more popularity, and it's an orthodontic alternative that doesn't sacrifice comfort and convenience for results.

More Adults Are Opting for Invisalign®

May 5th, 2021

These days it's becoming more and more common to see adults at our Denver, NC 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 Denver, NC 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. Todd Hamilton and Dr. Bryan Whitecotton know. We'd be happy to help you on your journey to a straighter, healthier smile!
