Dr. DeCasperis and our staff rely on digital X-rays to help us diagnose oral conditions and process images at incredibly high speeds. You can also view digital X-rays in real time while we examine your mouth with an intraoral camera and upload the images to a software program. A chairside computer monitor lets you see these images as we refine areas of concern to ensure an accurate diagnosis.

But are dental X-rays safe?

Yes! They emit 80 percent less radiation than exposure-type X-rays and provide detailed images to improve diagnosis and treatment. We can now detect dental problems in their earliest stages without subjecting you to unnecessary radiation. The amount of radiation released by digital X-rays is “negligible,” which means the amount is so small, that it can be safely disregarded.

Safe enough for children and pregnant women, digital X-rays detect microscopic pitting in tooth enamel and other abnormalities in the oral tissues that might have remained undetected with traditional X-rays. When Dr. DeCasperis and our staff discover dental caries in their earliest stages, we can initiate treatment measures that will effectively prevent cavity development, tooth decay, and potential tooth loss.

Patient appointment lengths are shortened with digital X-rays as well, because images are immediately viewable and do not require the exposure time associated with old-style X-rays.

How Digital X-Rays Differ from Traditional X-Rays

Instead of using cardboard-contained film, we insert a small sensing device about the size of a pen in your mouth and engage the digital X-ray machine by manually manipulating control buttons. Within seconds, images appear on the monitor that can later be stored in your file or sent to another doctor for further examination.

The increased resolution afforded by digital X-rays means that patients are able to understand the seriousness of their dental issues better, and are more inclined to follow through with procedures recommended by Dr. DeCasperis.

Safer, Better and Faster

For detection of cancerous tumors in their early states, digital X-ray technology offers vast improvements over film X-rays because of its cutting-edge image processing capability. Early detection of oral cancer and dental caries is the best way to prevent any type of oral health problem from exceeding the treatable stage.

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. DeCasperis 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 Lebanon, NJ 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!

You have probably counted a hundred reasons to stop smoking. It’s unhealthy. It’s expensive. It annoys the people around you. You have to schedule your day around the next cigarette. But here’s reason number 101: Did you know that one of the many side effects of smoking is the damage it does to your smile?

Your Appearance

One of the most obvious results of smoking is the constant yellowing and discoloration of your teeth. Tobacco stains can take longer to remove with home brushing and whitening. And, while a professional cleaning and whitening will make a world of difference, all that good work is undone once you start smoking again.

More important, no smile looks its best with periodontal disease and tooth loss. Smoking has been linked to the presence of more harmful oral bacteria and higher occurrences of cavities and gingivitis (early gum disease). Periodontitis, or severe gum disease, is much more common among smokers. Tooth loss is also much more likely.

Healing after Dental Surgery

Smoking slows the healing process. It has been linked to a weaker immune system, so it’s harder to fight off an infection or to heal from one.  And because of the harmful effect of smoking on bone tissue, there is a higher failure rate for dental implants among smokers. Bone density can be so compromised that an implant is not even an option.

Healing after Extractions

If you have a tooth extracted, the formation of a blood clot at the site of the removal is essential to avoid a condition called dry socket. Dry socket can lead to pain, serious infection, and other complications. Luckily, this clot is resilient and pretty hard to dislodge—unless you apply suction such as sipping through a straw or drawing smoke from a cigarette.

Oral Cancer

Research has shown that smoking is the single most serious risk factor for oral cancer. The good news is that this risk is cut dramatically if you quit!

Let Dr. DeCasperis help you maintain your smile. We can offer many more reasons to give up the smoking habit, and we are happy to offer suggestions for quitting during your next visit to our Lebanon, NJ office. We want to protect your smile and your health as well. It doesn’t really matter which number on the list finally leads you to quit—every number on that list is your lucky number!

Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth which sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity which develops on one of those side surfaces of your teeth.

• Discovering Interproximal Cavities

Clearly, a cavity between the teeth won’t be as obvious as other cavities. How will you know if a dental appointment is in order?

There are typical symptoms which can show up when you have a cavity. Chewing might be painful. You might feel pain or sensitivity when you eat or drink something which is hot, or cold, or sweet. But pain and/or sensitivity aren’t always present, especially when a cavity is just beginning to develop.

Regular exams are important so you can catch small cavities before they become more serious. That’s why, at your regular dental exams, Dr. DeCasperis will always check for any signs of decay on every surface of each tooth, including those places which aren’t easily visible. And that’s why X-rays can be an important tool for locating these tricky cavities.

• Treating Interproximal Cavities

If Dr. DeCasperis and our team finds a cavity between your teeth, there are different treatment options available depending on the size of the cavity:

• A typical cavity will require a filling. The decay will be removed, and then the area will be cleaned and filled. You’ll probably choose a filling material which can be matched to your enamel color if the restoration will be noticeable.
• If decay has spread to the pulp chamber inside the tooth, a root canal is often the best treatment option, with a crown applied afterward to protect the tooth.
• A tooth so decayed or infected that it cannot be saved might require extraction.

Dealing with any weakness in a tooth as quickly as possible is always better than waiting until a more complicated treatment option is needed. Of course, the best treatment is prevention, and, luckily for us, it’s not a complicated process at all.

• Preventing Interproximal Cavities

In fact, it’s about as basic as it can be—brush and floss effectively. We recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gumline—places where bristles just can’t reach. The next time you get your teeth cleaned at our Lebanon, NJ office, ask for tips on how to perfect your technique. And, if you have difficulty flossing, ask about alternatives such as water flossers and interproximal brushes.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If Dr. DeCasperis and our team find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with us to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.
