Dental X-rays: The Inside Story

December 16th, 2020

We’re all friends here, so if you sometimes feel a bit nervous before your orthodontic appointments, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and your orthodontic options so you know exactly what is going on during treatment. 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 called 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 many different types of dental X-rays used in orthodontics, including:

  • 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.
  • Cephalometric X-rays, which show the patient’s entire profile, and the position and development of the 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?

You might have noticed that these X-rays, unlike, for example, typical bitewing X-rays, don’t take images of individual teeth. That is because orthodontists deal with the teeth in relationship to each other and to the structures around them.

Beautifully aligned teeth and a healthy bite are the visible result of your orthodontic work, but there’s a lot going on above and below the surface that needs to be discovered and taken into account before your treatment even begins. X-rays help us evaluate:

  • The size, shape, and position of your teeth, including impacted teeth and wisdom teeth
  • The size, position, and health of your roots throughout treatment
  • The size and shape of your jaw bones, and how they affect your teeth alignment and bite
  • Your progress during different phases of treatment

How Do Orthodontists 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 typical panoramic X-ray provides roughly the same amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Siobhan Sheehan 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 are changing orthodontists and have had previous orthodontic X-rays taken. Ask to have your older X-rays sent to our office so we have a complete record of your orthodontic history. (With digital X-ray technology, this transfer can be accomplished with e-mail!)
  • 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 orthodontic treatment provides you with a lifetime of beautiful and healthy smiles. If you have any concerns, contact our Duxbury, MA 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!

Water Flossers and Braces

December 9th, 2020

You devote a lot of energy to your orthodontic treatment. Appointments, rubber bands, adjustments, cleaning (so much cleaning)—and why? Because you know that your attractive, healthy smile will be well worth the effort.

But if you find that keeping your teeth and braces clean requires more time and energy than it should, and you’re still not getting the results you’d like, a water flosser might be just the tool you need to help make your cleaning routine easier and more effective.

Plaque and tartar can be a real problem when you wear braces. Cleaning around braces and wires can be a challenge, and it can be difficult to get floss between your teeth and close to your gums, even with special threaders or floss designed to slip behind your wires.

But ignoring bacteria and plaque build-up can lead to cavities, weakened or discolored enamel, and gum problems. Fortunately, a water flosser can help wash away food particles, bacteria, and plaque even in tight, hard-to-reach spaces, while providing gentle cleaning along sensitive gums.

Water flossers use a pulsing stream of water to remove food particles and plaque between and around teeth. You can adjust the water pressure to apply just the right amount of cleaning power, and then direct the flow to your gum line, between your teeth, around your brackets, or anywhere else you need. Some models even offer tapered heads with brushes designed specifically for cleaning braces.

You might consider investing in a water flosser if you have:

  • Mobility issues. If you have joint or mobility issues, a water flosser will let you clean those hard-to-reach areas more easily.
  • Lingual braces. Because lingual braces are on the inside of the teeth, they can be more difficult to clean effectively with regular brushing and flossing.
  • Problems removing plaque. If you find that you are brushing and flossing regularly, but still have plaque build-up around your braces, give water flossing a try.

A beautiful smile is well worth all the time and effort you are devoting to it. If you think a water flosser might save you a bit of that time and effort, and provide better cleaning power, talk to Dr. Siobhan Sheehan  about your options during your next visit to our Duxbury, MA office. We’ll let you know if traditional flossing, a water flosser, or a combination of the two will give you your cleanest, healthiest smile.

Spacing Out

November 25th, 2020

One of the most common reasons for getting braces is because there’s just not enough room for all your teeth to fit next to each other evenly. The result is overlapping and crooked teeth. What’s the first step in creating the space you need? Well, that depends on just how much room you need to align your teeth and bite properly.

When there is going to be a serious need for space, there are orthodontic solutions that can help, including palatal expanders, surgical options, and extractions. But if you only need a tiny bit of room so that regular braces will fit properly, we have a tiny solution—orthodontic spacers!

Why do you need to make space before you get braces? Because Dr. Siobhan Sheehan might need to make some room around crowded molars so your braces can be installed properly.

For example, you might need orthodontic bands to anchor your braces. An orthodontic band is a slim, custom-fitted ring of metal which fits snugly around a molar. It is durable, provides a place to attach bands and springs to help correct malocclusions (bite problems), and can securely surround a tooth that might be weak because of a large filling. Spacers can separate crowded teeth just enough to allow a band to be fitted around a molar.

Even if you don’t need bands, sometimes separators are necessary to provide enough space between the teeth for your braces to work effectively. The back teeth tend to move even closer together with braces, and, without adequate space, bite problems, risk of decay, and other difficulties can arise.

And while you might think that some serious equipment is in order to make room between those sturdy molars, the typical spacer, or separator, is actually extremely simple--usually a tiny, round elastic band, often made of rubber. Spacers can be placed between tight teeth in a matter of minutes. Each ring is stretched and positioned between your teeth with a special tool. As it returns to its original shape, the spacer’s width provides just enough pressure on the teeth it touches to make a bit of space between them. And a bit of space is usually all you’ll need.

What do spacers feel like? For some people, they can be uncomfortable. You might feel soreness, some pressure, or as though a piece of food is stuck between your teeth. Ask us for suggestions on making you more comfortable, whether it’s dining on ice cream and cold drinks, eating soft foods, or taking over-the-counter pain relief. Separators are only designed to be in place for a very short period (usually under two weeks), but if they are causing you pain, give us a call.

What do you need to do to help the process along? Actually, it’s more what you need not to do. Don’t use dental picks or floss on your separators, avoid chewing gum, and take chewy and sticky foods off the menu. And don’t be tempted to touch or play with your spacers!

Spacers can create space between the teeth so quickly and efficiently that they often fall out on their own after a few days. If your separators fall out, give our Duxbury, MA office a call. It could mean that you are ready for your braces, and on the way to a lifetime of healthy, beautiful smiles. And it’s a journey that begins with a tiny, springy step.

Wax Facts

November 11th, 2020

In the long run, wearing braces is so worth it. Whether you’re working toward straight teeth, an improved bite, or both, you’ll end up with a beautiful smile! But sometimes, in the short run, they can be really annoying. Braces can irritate your lips, tongue, and cheeks while you are getting used to them or after an adjustment. Or a problem wire can poke the inside of your mouth and you can’t see us immediately for a repair. At times like these, Dr. Siobhan Sheehan will recommend orthodontic wax to make your life more comfortable.

  • What is Orthodontic Wax?

Orthodontic wax is made from non-toxic products like beeswax, carnauba wax, and paraffin wax. Some products might contain extras like vitamin E, aloe, or flavorings. The soft wax covers the bracket or wire that is bothering you with a smooth surface that won’t irritate sensitive mouth tissue and will give sore areas a chance to heal.

  • What if I Swallow a Piece?

All dental wax is made of non-toxic ingredients. If you accidentally swallow a bit, no need to worry.

  • Is It Hard to Apply?

It’s not hard, but it takes a bit of practice. First, locate the wire or bracket that is causing the problem. You might know where it is right away, or be able to discover it by discovering which sharp bracket or wire is across from the sore spot in your mouth.

Always wash your hands first. Brush and floss, so you will have a clean surface to apply the wax. The drier the surface, the better the wax will stick, so let the area air dry or use something clean such as sterile gauze to dry around the bracket.  

The wax is actually quite easy to work with. Break off a small piece of wax (no bigger than the size of a popcorn kernel or a pea), roll it in your fingers to soften it, and press the wax firmly but carefully over the problem bracket or wire until it sticks. Rub until the wax is smooth. Don’t worry, we will be happy to show you just how it’s done.

  • Can I Eat with Wax in Place?

If you find that you can eat without much irritation, it’s better to eat without wax over your braces. Remove the wax before eating and brush carefully to remove any food particles from your braces before applying new wax. If you do snack while using wax, be sure to change it after you eat. Wax, after all, sticks easily to your braces—and food particles stick to wax! Not a good look, and not good for your teeth.

  • Brushing and Flossing

Take off any wax before you brush and floss. Your toothbrush will thank you!

You probably have lots of other questions. Can you sleep with wax on your braces? Will it help you be more comfortable at trumpet practice? That’s why we’re here! If you have any questions at all about orthodontic wax and how to use it, call our Duxbury, MA office. We want to make sure that the months you spend wearing braces are as comfortable as possible on your way to a lifetime of beautiful smiles. It’s so worth it!
