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, Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough 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 Kingston, ON 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!

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 Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough when you visit our Kingston, ON office for the safest, most effective way to treat your child’s compromised tooth.

Let’s face it, by now, brushing our teeth is something we pretty much do on auto-pilot. A quick brush after breakfast, a minute or so at night, floss when we think of it. Done. But take a few minutes to review these cleaning tips, and see if a few small adjustments to your routine could make all the difference at your next checkup at our Kingston, ON office.

• Tools

Some of us prefer brushing with a manual brush. Some like the electric brush for ease and comfort. Whichever form of brush you choose, be sure that it fits comfortably in your mouth, reaches everywhere it needs to, and has a handle that is easy to grip. There are many bristle options available, so if you are an energetic brusher, or if you have sensitive gums, try a soft bristled brush for gentler brushing.

If you haven’t been exploring the floss aisle lately, there are now many varieties available to suit your particular needs. Besides the traditional floss, there are coated flosses for easy gliding between teeth that fit closely together, dental tape-style flosses to fit teeth with wider spacing, and even flosses designed just for braces that thread between the wires and brackets. Talk to Drs. Tom Holmes, Gordon Lansdown, Karen Nesbitt, Nick Cosman, Brett Empringham, and Patrick McDonough at your next cleaning for product suggestions if you think there’s an easier, more comfortable option out there for you.

• Technique

With proper technique, any toothbrush and floss you choose will do a fine job of removing plaque.

Brushing? There’s a tried and true method for success. Place the toothbrush at a 45° angle at the gum line. Be sure to brush the outside, inside, and chewing surface of each tooth thoroughly. Remember the expression, “Massage, don’t scrub.” Over-vigorous brushing can actually irritate gum tissue and damage enamel. An electric toothbrush should provide a continuous brushing motion without needing any pressure from the brusher. This might be the model for you if you have a too-vigorous approach to brushing, or sensitive teeth and gums. If you like your manual brush, again, give a soft-bristled brush a try!

As for flossing? That harmless-looking little string can cause gum damage if used too forcefully. You can accomplish the placement and cleaning power you need by easing the floss down to the gumline and flossing with gentle pressure against the tooth surface. If you have any questions about technique, remember—we are always happy to let you know the best cleaning methods for your specific needs.

• Timing

Of course, the best tools and the best technique in the world won’t be effective unless you put the right amount of time into brushing and flossing.

The standard rule is two minutes of brushing in the morning and two minutes at night. If you wear braces or have other special circumstances, we might recommend brushing after every meal. And if you brush after breakfast, give your teeth half an hour or so to remineralize. This natural process uses the calcium and phosphate ions in your saliva to strengthen tooth enamel after it’s been exposed to any acidic foods in your breakfast.

Thorough flossing can be accomplished in a few minutes, and might be needed only once a day. But again, depending on your individual needs, we might have other recommendations. Let’s review what works for you at your next visit—we can tailor suggestions for a brushing routine to your unique needs.

It’s a great idea to review your brushing habits periodically to make sure you are getting the most out of those minutes you spend cleaning your teeth. There won’t be a test at the end of this review, and you won’t get a gratifying grade or a gold star. What you will get is much more important—better checkups, fewer cavities, and healthy teeth and gums. Happy cleaning!

Pediatric dentists strive to make your children’s visits welcoming and worry-free, and, we want the same for you! Ask us about any questions you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your child’s experience can be. And if X-rays are a concern, we can put your mind at ease here as well.
