Safety of Dental X-Ray Radiation

September 25th, 2024

We all want to live our healthiest lives. We know that part of keeping ourselves healthy is regular visits to our Boston, Massachusetts office for checkups and necessary dental work. And that dental work might require an X-ray. Should the amount of radiation in an X-ray concern us?

First, it is helpful to know that the radiation you are exposed to from a dental X-ray is very small. A set of most bitewing X-rays, for example, produces an amount of exposure about equal to the amount of background radiation we get from our normal surroundings in a typical day. We also take care to minimize your exposure even further by using specially designed equipment and protective shielding, and taking only necessary X-rays. If your child is very young, if you are pregnant, or if you have other health concerns, talk to us about the advisability of X-rays and whether they are essential to treatment.

Second, much of our careful general examination will be done visually. John Pappas can check for cavities and other problems and assess tooth and gum health. But sometimes, there are conditions which can’t be detected without an X-ray.

  • Decay that isn’t visible in an oral exam—if a small cavity develops between teeth, or is hidden underneath a filling, an X-ray will catch it before more damage can take place.
  • Infection—An X-ray will reveal infections such as abscesses that can damage both bone and tooth, and gum disease that has harmed bone and connective tissue.
  • Orthodontic and periodontal issues—We might need an X-ray to determine the spacing and development of your child’s incoming teeth and maturing jaw structure, to properly create braces for adults or children, or to place an implant within the jawbone.
  • If you are a new patient, it is helpful to have complete X-rays taken as a baseline of your current dental health and previous dental work. This baseline allows us to track tooth and jaw development, if necessary, and to evaluate any future changes that might be a concern. (If you have had X-rays taken in another office, we can help you have them transferred so we have a background of your dental history.)

Even though the radiation from a dental X-ray is minimal, be assured that we will never request any unnecessary procedure. When we recommend an X-ray, we do so to make sure there is no decay or infection threatening the health of your gums and teeth, and that we have the essential knowledge we need to treat any dental, periodontal, or orthodontic condition. Because we all want to live our healthiest lives—and part of that healthy life is both active and proactive dental care.

Summer Smiles

September 5th, 2024

The “Back to School” ads are out already? Halloween candy’s showing up in stores? Just a minute—summer isn’t quite over yet! While the days are still warm, let’s look at a few cool ways to keep your smile bright with some healthy dental options:

  • Healthy Drinks

Hot summer days mean it’s time to hydrate. But sodas, fruit drinks, and sports drinks can have a lot of added sugars, which can mean added cavities. They can also be quite acidic, and acids break down tooth enamel. So, what to reach for on a hot day? Water!

Water is a good choice whenever you’re thirsty. Water is essential for healthy bodies and for healthy teeth and gums, too. Water helps wash away food particles that feed the cavity-causing bacteria in plaque. Acids in our foods and drinks break down tooth enamel, and water helps balance out those acids. If you have fluoridated water, fluoride makes enamel stronger and even helps reverse early decay. And it’s easily available and very cost effective!

  • Healthy Gear

Make sure that healthy smile you worked so hard for stays looking its best with protective gear:

  • A mouthguard will help protect your teeth and mouth from contact with hard surfaces and hard bodies when you’re enjoying biking, baseball, hoops, and other activities.
  • If you have a retainer, wear it as directed. Retainers keep your teeth from moving out of position while your jawbones rebuild strong bone tissue around them.
  • If you suffer from bruxism, your nightguard protects your teeth and jaws from tooth-grinding damage, so don’t forget to use it nightly.

Your appliances protect you, so return the favor and make sure your appliances stay healthy by cleaning them after use and storing them in their protective cases.

And remember to replace another piece of protective equipment regularly—your toothbrush. If you haven’t replaced your toothbrush for several months, it’s time to go shopping. Toothbrushes wear down over time, and, after three months or so, can’t clean plaque as effectively. Which reminds us . . .

  • Healthy Habits

Even as we take advantage of the end of summer with last minute camping, or travel, or action-filled weekends, one thing should stay on schedule—regular brushing and flossing.

You should be brushing twice a day, for two minutes each time. If it’s hard to time yourself, try playing a favorite two-minute song or using a timer or even a brushing app. And don’t forget to floss! Floss gets into spaces where bushes can’t to remove plaque. Floss once a day to keep your teeth their cleanest.

Finally, don’t forget to schedule regular dental appointments at our Boston, Massachusetts office for a cleaning and exam with John Pappas.

Summer’s almost over, but these healthy tips work in fall, winter, and spring, too—for a smile that’s sunny and bright all year long!

Educational and Entertaining Enamel Experiments

August 28th, 2024

Let’s talk about the science of our teeth for a moment. Our enamel has a very high mineral content, making it extremely strong.  In fact, enamel just happens to be the hardest substance in our bodies.  But, unfortunately, it is not indestructible! Certain foods we eat can actually damage the surface of our teeth. Some simple and entertaining experiments can show children how our teeth can be affected by things we eat and drink, and how we can help protect them.

If you have a science-minded student at home, there are many activities you can do together, using educational websites, common household products and lots and lots of eggs. (Why eggs? Eggshells are a great substitute for teeth in these experiments. Not only are they various shades of white--like our own teeth, they are also calcium-rich—like our own teeth.) You can find any number of experiments using uncooked eggs, hardboiled eggs, whole shells with the contents blown out, or eggshells alone, so you can find just the right activity for whichever egg treatment works best for you.

Examine Enamel Erosion

One of the ways we protect our teeth is with healthy eating. The bacteria in plaque use the sugars and starches in our foods to produce acids. These acids are the substances that break down the minerals in our enamel and leave the enamel weaker. Weaker enamel is more easily attacked by bacteria and acids, which leads to cavities.

With eggs or eggshells and some carefully selected food products, you can see just how acidity affects teeth. Different websites suggest a variety of acidic liquids to dunk your eggs in, such as vinegar, soda, or citrus juices, so it’s easy to find an experiment that works with your pantry. Always use a plain water sample when you submerge eggs or shells to act as a control to measure differences against. How do the egg shells soaked in acidic liquids differ from those in plain water? It’s also fun to add simple sugar water as a test liquid to see what happens. Is it sugar or acid that causes more damage? And why might that be?

The Fluoride Fix

Fluoride is well known as a mineral that protects the structure of our teeth and helps prevent cavities. And there are actually experiments out there to test the protection fluoride provides using your egg stand-ins.

In some experiments, a hardboiled egg is coated with fluoride toothpaste or rinse for a specific amount of time and then dunked into vinegar. An untreated egg also gets a vinegar bath. You are asked to observe what is happening to each egg as it sits in its vinegar bath—are there bubbles on one egg and not the other? What do the bubbles mean? Other experiments require longer exposure to fluoride and then to vinegar—what happens to the shells of the treated and untreated eggs? What could this mean for our teeth?

Staining Studies

Our diet can do more than help create cavities. Enamel is very strong, but it is not stain-proof! Dark colored foods and drinks can make our teeth appear darker or more yellow. (And teeth that have suffered enamel erosion can pick up stains more easily.) How does food affect the brightness of our smiles?

If this question interests you, find experiments that use favorite beverages as a soak for your eggs. Choose liquids with a range of color, such as coffee, soda, and apple juice. Or choose an experiment that uses different varieties of soft drinks. Will foods the same color cause the same amount of discoloration in your egg volunteers? Do you want shorter or longer soaks in each liquid? Do you want to make use of a recycled toothbrush to see if brushing that discolored shell makes a difference? With toothpaste or without?

Even though these activities are designed for older children, they still require adult supervision. You can find detailed instructions for any of these experiments at many science and educational sites online. With some household supplies, plenty of extra cups, and a quantity of eggs, you and your child can demonstrate some of the basic effects our food choices have on the health and appearance of our teeth. It’s a wonderful way to promote healthy eating and brushing habits, scientific curiosity, and shared experiences!

Don’t forget to let John Pappas know how your experiments turned out the next time you visit our Boston, Massachusetts office!

How Missing Teeth Can Affect Your Health

August 22nd, 2024

According to the American Academy of Periodontology, an estimated three out of four Americans suffer from gum disease. In milder cases, the disease is called gingivitis. More severe cases are called periodontitis. Despite the prevalence of periodontal disease (and it is very common), only three percent of people who suffer from periodontal disease get treatment for it. Gum disease has been linked to other serious diseases, including cancer, diabetes, and heart disease.

Periodontal Disease Is Common Among Americans

The Journal of Dental Research published the findings of a joint study from the Centers for Disease Control (CDC) and the American Academy of Periodontology (AAP). The study compared the full periodontal exam that participants received for this study against partial periodontal exams participants received for an older study.

The results show the rate of periodontal disease today could be as much as 50 percent higher than earlier estimated. Shockingly, this means that about twice as many Americans as previously believed suffer from gum disease – either moderate or severe.

The Link between Chronic Illness and Periodontal Disease

Many people who have chronic medical problems don’t have dental insurance, or the money to spend on dental care. Not surprisingly, this and a lack of understanding about proper oral hygiene leads to situations in which an initially minor problem turns into something far more severe, and probably preventable.

Gum diseases and cavities are caused by infections. When you get a cavity, the infection develops in the tooth itself. You may never feel anything, so unless you get regular, twice-a-year dental exams, you might not know there is a problem.

With gum disease, the infection occurs in the bones and tissues that form the gums and support the teeth. The tissues that surround teeth, and the bones that lie below the gums, are necessary to hold your teeth in. When those aren’t strong enough to support your teeth, you lose them.

Tooth loss has been linked to heart disease, diabetes, and an increased risk for kidney disease. Gum disease and severe infections in the mouth can spread to other parts of the body faster than people realize. A healthy mouth is alkaline. It’s vital for you to maintain an alkaline pH to keep harmful bacteria away.

When people eat, their pH changes, and the environment inside the mouth becomes more acidic. Since the typical American diet is very acidic, harmful bacteria thrive in the mouth. Typical foods include breads, grains, starches, and sweets – the foods people love the most. Since it isn’t always possible for people to brush after every meal, the mouth pH remains acidic, and the acid contributes to faster tooth erosion.

What does all this mean for you? The health of your mouth is more important than you realize. Get those regular dental exams, and make sure that you and your family keep to a regular routine of brushing and flossing. Good oral hygiene can help prevent periodontal disease, and that will lower your risk of tooth loss.
