Dental X-rays: The Inside Story

February 15th, 2023

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. Sheena Allen, Mark Margolin, and Moein Sadrkhani 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 Dallas 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!

Brushing Your Toddler’s Teeth

February 8th, 2023

At Dallas Dental Arts, we know that brushing your toddler’s teeth can be an intimidating prospect. So we’re providing a few tips in the hope of making the process a lot more easy, effective, and all-around enjoyable for everyone!

Start by getting into a position that gives you control and enables you to see well into your child’s mouth. If you can see clearly, you will be able to maneuver the toothbrush better around your son or daughter’s mouth for a better quality of brushing.

It’s important to choose a time when your toddler is calm. Have your little one sit with his or her favorite stuffed animal, or play a fun movie in the background so your child can focus on something comforting while you’re brushing.

Using a circular motion, brush all sides of their teeth. Be sure to let your toddler have a turn after you’re done, to start getting used to it. This way, he or she is more likely to repeat the brushing and flossing exercise when your youngster is old enough.

Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team agree that brushing and flossing need to be performed with kindness and care. To ensure your child learns good dental hygiene habits early on, be gentle and make this time a happy, learning time.

Your child should also have regular appointments at our Dallas office for checkups and cleanings to keep on track!

Are there foods that whiten teeth?

January 25th, 2023

Coffee. Blueberries. Red wine. Tomato sauce. They might please our palate, but they are notorious for staining our teeth. Luckily, nature has balanced the scales for us! Here are just some of the foods that could actually help whiten your smile.

Apples

The crunchy texture of an apple makes it perfect for scrubbing your teeth as you chew. The more you chew, the more saliva you produce. And saliva helps lower the amount of the bacteria in our mouths that cause decay, while washing away food particles that can stain our teeth.

Broccoli

Raw broccoli florets look—and act—like tiny toothbrushes. Broccoli also contains high levels of iron which help protect our enamel from stains and erosion.

Carrots and Celery

More crunchy vegetables that scrub teeth. These are high in fiber, which acts as a gentle abrasive, and water, which stimulates healthy saliva production.

Nuts and Seeds

These are nutritious snacks that both act as abrasives and increase saliva production.

Pineapple

Pineapple is that rare fruit that produces bromelain, enzymes that help in digestion. These enzymes are also believed to help remove staining.

Strawberries

Malic acid considered by many to be a natural whitener which helps break down stains, and strawberries are a great source for this organic compound. But don’t overdo, because too much acid is hard on your enamel.

Of course, the real benefit of eating a balanced diet containing fresh fruits, vegetables, nuts, and seeds is nutritional, and any whitening that takes place is an added bonus. And eating healthy foods won’t take the place of brushing to keep your teeth clean and bright, especially if you are relying on sugary fruits for their whitening effect. If you want help whitening your smile, and diet and brushing alone aren’t the answer, give our Dallas office a call and we’ll be happy to suggest other options. Until then, bon appétit!

Flossing Fact or Flossing Fiction?

January 25th, 2023

Somewhere in a bathroom drawer or medicine cabinet, we all have one—that little plastic dental floss dispenser. And whether you use your floss every day (yay!), or have completely forgotten it was in there (not so good), just how much do you know about that sturdy string? Let’s find out!

  • Flossing has been around for hundreds of years.

FACT: It’s been just over two hundred years since Dr. Levi Spear Parmly, a dentist in New Orleans, suggested his patients use waxed silk thread to clean between their teeth. This is considered the first “official” invention of dental floss, although using some form of tool to get rid of food particles between the teeth has been around since prehistoric times.

  • Brushing well is the same as flossing.

FICTION: It’s really not. While brushing does a great job of cleaning food particles, plaque, and bacteria from your enamel, there are some places those bristles can’t… quite… reach. Floss was designed to clean plaque and food from between the teeth and close to the gum line where your brush doesn’t fit.

  • There’s more than one way to clean between your teeth.

FACT: Indeed there is! Not only are there many varieties of dental floss (waxed, flavored, round, flat, thick, thin, in a dispenser, attached to miniature floss wands), but you have alternatives if using any kind of floss is difficult for you. Water-flossers direct a pulsing stream of water between and around the teeth and gum line to remove food particles and plaque. Another useful alternative is the interproximal brush, a tiny little cone-shaped brush designed to remove food and plaque from those hard-to-reach spots.

  • Flossing helps prevent gum disease.

FACT: Scientific studies haven’t provided definitive answers. But Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team strongly recommend daily flossing as one of the most important things you can do to prevent gum disease. Gingivitis, or mild gum disease, is caused by irritated, inflamed gum tissue. Gum tissue becomes irritated and inflamed as a response to the bacteria, plaque, and tartar, which stick to your teeth. Anything you can do to help remove these irritants will reduce your risk of gum disease.

  • Flossing helps prevent cavities.

FACT: We strongly recommend daily flossing to remove the food particles and plaque, which lead to cavities. Brushing removes cavity-causing plaque from the outer surfaces of your teeth. But there’s a lot of enamel between your teeth as well. Flossing removes plaque from these hidden spots, helping to prevent interproximal (“between the teeth”) cavities from forming.

  • Bleeding when you floss is normal.

FICTION: Bleeding isn’t a typical reaction to flossing. Bleeding gums could be an early sign of gum disease caused by plaque and tartar buildup. On the other hand, if you floss too hard, or go too deeply below the gum line, you can make delicate gum tissue bleed. Ask Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani for tips on perfect flossing technique.

  • You need to floss after every meal.

FICTION: Dental professionals generally recommend brushing twice a day and flossing at least once each day. But this suggestion comes with some exceptions. If you have braces, your orthodontist might recommend flossing after eating. And certainly, for removing pesky food particles, flossing or interdental picks are a sensible choice after any meal.

  • Your dentist will never know that you haven’t been flossing.

FICTION: Nope. Sure, you can miss flossing a few times and catch up before your appointment at our Dallas office. But built-up plaque between the teeth, red, swollen, or bleeding gums, and gingivitis and interproximal cavities let both you and Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani know that you’ve been neglecting good dental habits.

  • It’s never too late to start flossing!

FACT: Flossing is a simple, quick, and inexpensive way to maintain tooth and gum health. If you haven’t had much luck flossing in the past, ask Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani for flossing tools and techniques that will work for your specific needs. Start now, and see what a difference it will make at your next checkup!

If you had all these flossing facts at your fingertips, congratulations! But if you didn’t, no need to worry, because the real test of your knowledge is in its application. Flossing properly at least once each day will give you something far more rewarding than blog-quiz kudos—you’ll see that regular flossing rewarded with healthier teeth and gums!
