We’re all friends here, so if you sometimes feel a bit nervous before your dental appointment, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your experience can be. 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 termed 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 different types of common dental X-rays which are used for a number of reasons:

• Bitewing X-rays, which are used to check on the health of the back teeth.
• Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
• 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.
• 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?

If all of our dental conditions were visible on the surface, there would be no need for X-rays. But there are many conditions that can only be discovered with the use of imaging—infection, decay, a decrease in bone density, or injuries, for example, can show up as darker areas in the teeth or jaws. Among their many diagnostic uses, X-rays can help us find:

• Cavities between teeth or under old fillings
• Damage to the tooth’s pulp which might require root canal treatment
• Injuries to teeth or roots after trauma
• Abscesses, tumors, or other conditions that might be causing swelling or pain
• Position and development of wisdom teeth
• Ideal placement for implants
• Health and density of the jaw and alveolar bone

X-rays can also serve an important preventative role, by discovering small problems before they become major ones.

How Do Dentists 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 set of bitewing X-rays exposes us to slightly less than the amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Michelle Slezewski and Dr. Paul Engibous 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’re a new patient, with previous X-rays taken during regular exams or for specific procedures. Ask to have your older X-rays sent to our office. With digital X-ray technology, this transfer can be accomplished with e-mail! Having your dental history available lets us notice any changes that have taken place.
• 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 teeth stay their healthiest. If you have any concerns, contact our Anchorage, AK 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!

X-rays are a vital diagnostic tool for any dental professional. X-rays help your endodontist perform a root canal, your orthodontist check the position of a tooth’s root, your oral surgeon discover a fracture. X-rays reveal what we can’t see with the naked eye—and that’s why they are an especially important tool for Dr. Michelle Slezewski and Dr. Paul Engibous as well.

Why Are X-rays Necessary?

There’s a lot going on below the surface. An X-ray can reveal such conditions as cavities between teeth or underneath fillings, abscesses and other infections in the bone, impacted wisdom teeth, and cysts and tumors. They can also show the size, shape, and density of the bone beneath the teeth, which is essential information for dental implant procedures or dentures.

How Do X-rays Work?

Traditional X-rays, or radiographs, make use of film just like traditional cameras. When you have an intraoral X-ray, for example, the film is sealed in a moisture- and light-proof packet, and placed inside the mouth to capture images of specific teeth and the bone around them.

The X-ray machine is aligned precisely with the film and an exposure is taken. The image at this point is latent, and won’t show on the film, because, just like photo film, traditional radiographs need to be chemically processed before they produce a visible image.

Digital technology, on the other hand, uses an electronic sensor instead of film. For an intraoral digital X-ray, a small sensor is positioned in the mouth just like a film. When the X-ray is taken, a digital image capture device produces an image which is formed by a matrix of pixels instead of a photo-like film exposure. This format allows the image to be sent directly to a computer for immediate display without requiring processing.

Even though these methods seem very similar, digital X-rays offer some significant advantages over traditional films. Let’s look at how they compare, more or less.

• More Diagnostic Advantages

A traditional X-ray is a fixed image. It cannot be modified or enhanced. Here the digital X-ray offers a clear advantage in diagnosis.

Just as you can enlarge certain types of images on your computer without blurring or losing detail, a digital X-ray uses computer software to magnify images while keeping their details sharp. They can also be enhanced through brightness and contrast applications to make details stand out even more. Both of these benefits are extremely helpful for diagnosis, especially when looking for small cavities, problems in the roots and surrounding bone, or developing wisdom teeth.

There is even digital subtraction radiography software available that can be used to compare recent images to older ones, removing (“subtracting”) all the similarities in the two images to display only the changes in the two—even small changes—that have taken place over time.

• Less Exposure to Radiation

Dental X-rays expose patients to very low levels of radiation, and modern technology means traditional X-rays expose patients to less radiation than ever before. Even so, digital X-rays have significant advantages. Radiation exposure can be reduced by an additional 10%, 20%, or more with a digital radiograph.

• More Convenient for Sharing and Transmitting

If you need to share your X-rays with another dental specialist or physician, digital technology allows you to simply have them e-mailed to another office or multiple offices. You no longer need to worry about preserving physical copies, either.

• Less Waste

Unlike traditional X-rays, digital X-rays don’t need to be processed, so you save time in the office. And while the processing time is not significant (usually several minutes), if you need to repeat some X-rays for a clearer picture, or require different images for several teeth, this time can add up.

Digital X-rays are also more eco-friendly.  The fact that they don’t need to be developed means that the chemicals used to process traditional films are no longer necessary—which also means that there is no need to dispose of chemical waste products afterward.

Our goal is to provide you with the safest, most efficient, and most effective dental treatment possible, and digital X-rays help us do that. If you have any questions about digital X-ray technology, contact our Anchorage, AK office. We’re happy to explain the science—and the benefits—of high-tech radiography.

Baby teeth come with a built-in expiration date. That charming first smile is meant to make way for a healthy, beautiful adult smile. Unfortunately, before they are ready to make way for permanent teeth, primary teeth can be affected by decay, trauma, or infection—problems which can lead to damage to the pulp within the tooth. If your dentist tells you that your child’s tooth needs specialized endodontic treatment, is treatment really that much better for your child than losing a baby tooth prematurely?

Quite often, the answer is yes!

Baby teeth do much more than serve as temporary stand-ins for adult teeth. They are essential for:

• Biting and chewing—a full set of baby teeth helps your child develop proper chewing, which leads to healthy digestion. And chewing also helps build face and jaw muscles.
• Speech development—primary teeth help guide speech production and pronunciation.
• Spacing—a baby tooth serves as a place holder for the adult tooth waiting to arrive. If a primary tooth is lost too early, the remaining baby teeth may drift from their proper location. This, in turn, can cause overcrowding or misalignment of the permanent teeth when they do erupt.

Baby teeth, like adult teeth, contain living pulp tissue. The pulp chamber inside the crown (the visible part of the tooth) and the root canals (inside each root) hold nerves, blood vessels, and connective tissue. When the pulp is damaged by trauma or infected, a baby tooth can still be saved with endodontic treatment. Endodontic treatment in baby teeth can take two forms.

• “Vital” pulp is pulp that can be saved. Vital pulp therapy uses procedures to deal with damaged pulp inside the crown, or visible part, of the tooth. Pulp therapy can be used on teeth when only the top of the pulp has been affected by decay, limited exposure, infection, or trauma, but the root pulp remains healthy. Specific treatment will depend on the nature of the pulp injury, and a crown will usually be placed over the tooth after treatment to protect it.
• With non-vital pulp, your dentist will probably recommend a traditional root canal procedure. All of the pulp tissue will be removed from inside the crown and the roots, and the pulp chamber and root canals will then be cleaned, disinfected, shaped, and filled. Finally, because the treated tooth will be more fragile, a crown will be used to protect the tooth from further damage.

There can be good reasons for extracting a seriously damaged baby tooth, and there are situations where preserving the tooth is the best and healthiest option for your child. Discuss your options with Dr. Michelle Slezewski and Dr. Paul Engibous when you visit our Anchorage, AK office for the safest, most effective way to treat your child’s compromised tooth.

Sherlock Holmes, that most famous of fictional detectives, observed clues, analyzed them, and used his powers of deduction to arrive at the solution to his cases.

Dr. Michelle Slezewski and Dr. Paul Engibous and our team are skilled in deduction as well! By examining your teeth and gums during your regular checkup, important clues can be discovered about your dental health—and perhaps your overall health as well. What might be deduced when you come in for an exam?

• You Haven’t Been Flossing

Even with some last-minute catchup flossing, it’s not hard to tell if you’ve been regularly skipping the flossing portion of your daily dental care. Plaque that your toothbrush just can’t reach on its own will be noticeable between your teeth and around the gum line. Your gums might be inflamed, swollen or bleeding—early signs of the gum disease plaque causes when it’s not removed with careful flossing.

These symptoms could arise because you’re neglecting to floss at least once a day, or it could be that your flossing skills could simply use some fine-tuning. A refresher in flossing technique takes no time at all. Or, you might discuss whether a water flosser would be a good investment for healthier teeth and gums if, for any reason, you have difficulty flossing effectively.

• You Haven’t Been Sleeping Well

Even if your roommate or partner hasn’t told you that your teeth and jaws have been grinding away while you were not-so-soundly asleep, your dentist might be able to. Shorter, flattened teeth are a common symptom of bruxism, or tooth grinding. Your exam might reveal cracked enamel or broken cusps caused by the force you’re placing on them at night. This condition can also lead to larger jaw muscles and jaw pain.

Since these symptoms are also caused by sleep apnea, it’s a very good idea to find out what’s causing this dental stress. Treatments are available to make your sleep safer for your teeth and jaws—and more restful and healthier for you!

• You Should Talk to Your Doctor

Conditions that seem to have nothing to do with your oral health can cause dental symptoms, alerting your dentist to a medical condition which you might not be aware of. Pale gums or a swollen tongue could be symptoms of anemia. Erosion on the inside of the teeth can be caused by GERD, or gastroesophageal reflux disease. Vitamin and mineral deficiencies can lead to ulcers, loose teeth, and gum disease.

 If Dr. Michelle Slezewski and Dr. Paul Engibous and our team suggest that you make an appointment with your doctor to find the medical cause of your dental symptoms, it’s essential to follow up.

• Are You Left-Handed?

So, getting back to our original question, can your dentist deduce that you’re left-handed?

Probably not! It’s been suggested that left-handed people brush their teeth more firmly on the left side, and right-handed people brush harder on the right. And it’s also been suggested that left-handers don’t brush the left side of the mouth as thoroughly, while right-handers neglect their dominant side.

But Dr. Michelle Slezewski and Dr. Paul Engibous can still tell you some important facts about your hand-brush coordination just by observing the state of your enamel. If you’re brushing too firmly, your tooth surfaces could show erosion and wear. A soft-bristled brush and a lighter hand will get your teeth just as clean without the abrasion.

If you’re having trouble reaching areas because of dexterity issues, Dr. Michelle Slezewski and Dr. Paul Engibous can point out the areas where plaque buildup reveals the spots you need to concentrate on. An electric toothbrush might be just the answer to making all the surfaces of your teeth equally accessible.

A dentist is an expert in observing, analyzing, and solving dental problems. When you keep to a regular schedule of exams and cleanings at our Anchorage, AK dental office, you’ll benefit from that expertise to discover oral health issues before they become more serious. That’s an easy and elegant solution to maintaining your dental health. In fact, it’s elementary!
