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. Kathleen Chan and Dr. Ivy Chen 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 Andover 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!

When you start wearing braces, it can become a challenge to clean certain areas of your mouth. If these areas are neglected for long periods of time, though, decay and stains can form on your teeth.

Your mouth will require extra attention while you have your braces on. This can include using a special toothbrush to reach those spots, flossing every day, getting fluoride treatments, avoiding certain foods, and making sure to visit your dentist. Let’s take a closer look at what you can do to prevent decay during treatment.

When you get your braces on, Dr. Kathleen Chan and Dr. Ivy Chen will give you an interdental toothbrush that can be used to get to those hard-to-reach spots in your mouth. The brush has bristles that can easily remove food residue stuck between the wires in your mouth. We may also suggest using a WaterPik, which pulses a pressurized stream of water to remove excess food particles.

Brushing and flossing every day should always be a part of your oral health regimen, but this becomes especially crucial when you have braces. If food gets stuck between braces and sits on your teeth, decay and staining will start to occur. Dr. Kathleen Chan and Dr. Ivy Chen and our team recommend flossing at least once a day, and brushing and using mouthwash after every meal as long as you have braces.

If you don’t have the time, make sure at least to swish your mouth really well with water after you eat. It’s especially important to follow these steps after consuming sugary foods or beverages. It’s best to avoid sweets altogether when you have braces.

Making sure to visit your dentist at least twice a year for a routine cleaning can also help to prevent any decay from damaging your teeth while your teeth are encased in braces. Your dentist will remove any plaque or tartar that’s built up since your last cleaning.

Prevention is key when it comes to keeping your mouth healthy during orthodontic care with braces. Follow these tips and you’ll keep your teeth beautiful and healthy for the day your new smile is finally revealed!

When you get your braces, Dr. Kathleen Chan and Dr. Ivy Chen and our staff will also give you a list of foods you should not eat and things you should not do. Pay particular attention to these items to keep your teeth and braces safe.

Charms belong on bracelets. While you can decorate your braces with colored bands, hanging a charm off them is a bad idea. If you bite down on the charm, you could damage your braces or your teeth. You could also swallow your jewelry.

Never use your teeth as a bottle opener. This is just as important when you are wearing braces. While braces straighten your teeth, your teeth are moving in the process. That makes them weaker, and the metal in the braces does not make them invincible. Invest in a bottle opener; you can buy one for a few dollars, which is much less expensive than having to replace your braces.

Contrary to what you might think, your braces are not designed to work as a radio. There are tales of people who have picked up radio signals from dental fillings or braces. While this is remotely possible, attaching an antenna to your mouth is just not a good idea. You will get better quality music from a radio.

On the other hand, you can still kiss someone while wearing braces. In fact, even if both of you wear braces, the chances of your getting locked together are almost negligible. However, to avoid cutting your partner’s lips, kiss with caution.

If you have any questions about taking care of your braces, please ask Dr. Kathleen Chan and Dr. Ivy Chen and our staff. We want you to get the best results from your treatment without needless delays.

At Chan & Chen Orthodontics, we know orthodontic emergencies are neither convenient nor timely. If you are a patient of record, Dr. Kathleen Chan and Dr. Ivy Chen and our team are more than willing to see you after hours or over the weekend. As a general rule, you should call our Andover office when you experience severe pain or when you have a painful appliance problem that you can’t take care of yourself. We’ll be able to schedule an appointment to resolve the problem. If you have an orthodontic emergency after regular office hours, please give us a call and follow the emergency prompts to contact one of our doctors.
