Our team at Chan & Chen Orthodontics knows that there are many ways you can protect your pearly whites throughout your orthodontic treatment. If you follow the rules and brush your teeth twice a day, floss often, and protect your appliances from damage, you should have a successful treatment.

But did you know there’s another way to keep your teeth sparkling and healthy during your time wearing braces?

Fluoride, the mineral that helps you prevent cavities and tooth decay, can also help keep your teeth strong. Fluoride comes in two varieties: topical and systemic. Depending on your oral health or the recommendation of Dr. Kathleen Chan and Dr. Ivy Chen, you may be required to have a fluoride treatment every three, six, or 12 months. We may also prescribe a fluoride product such as a mouthwash, gel, or antibacterial rinse for at-home treatment to keep your teeth happy in between visits.

If you have any other questions about fluoride or your treatment, please don’t hesitate to give us a call!

It's springtime and it's again time to remind our patients at Chan & Chen Orthodontics to protect their faces and pearly whites while out on the field playing sports. According to the National Youth Sports Safety Foundation, children, high-school athletes and adults have more than 5,000,000 teeth knocked out in sporting events annually.

If you are planning on participating in spring sports, it’s imperative to have a proper-fitting mouthguard. Mouthguards can prevent chipped or broken teeth, lip and cheek injuries, jaw fractures, mouth lacerations and even concussions.

Having a mouthguard can make the difference between losing your teeth or not, and because many of our patients who play high school sports have jaws that are still growing, last year’s mouthguard may no longer fit as it should. Dr. Kathleen Chan and Dr. Ivy Chen and our team at Chan & Chen Orthodontics can fit you for a new guard.

There's something special about customizing the elastics on your braces to fit your unique personality. Once you embrace your braces (no pun intended) you'll realize how many color options and combinations there are to choose from. Although you'll have a fantastic smile afterward, you won't have this level of customizability once your braces come off, that's for sure!

Adding flair to your braces isn't what all patients are looking to do (like those opting for clear aligners or ceramic braces), but it's part of the fun of traditional metal braces! Many of our patients ask Dr. Kathleen Chan and Dr. Ivy Chen to have their elastics match the colors of their favorite sports teams or their school, but how about changing your elastics to match holiday colors?

Here are some options to consider:

• Valentine’s Day – Red and pink
• Easter – Pink, blue, and violet
• Halloween – Orange and black
• Christmas – Red, green, and white
• Saint Patrick’s Day – Green and white

There are a few colors that some people choose to avoid. But if you’re trying to make your teeth stand out in a crowd, the following suggestions need not apply!

• Brown or Green – can be mistaken for food being stuck in your teeth
• Black – might look like a rotten tooth if someone isn't looking hard enough
• White – Some patients think it will make their teeth look whiter, but in fact it can make your teeth appear yellower than they actually are. White elastics can also stain easily.
• Yellow – accentuates the yellowness of your enamel

Since changing the color of your elastics has no effect on the actual orthodontic treatment process, the idea is to have fun and add a personal touch. So, next time you get your elastics changed at our Andover office, why not wear your braces boldly and opt for something festive?

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!
