Modern orthodontic technology has changed the way you wear braces. Brackets are smaller and come in a variety of shapes and colors. Wires are more efficient. Clear aligners can eliminate the need for brackets and wires altogether. And your high-tech advantages don’t stop there—today’s digital X-rays make creating your treatment plan even more convenient and efficient.

Why Are X-rays Necessary?

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 Drs. Chen and Sepe 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
• The most effective type of retainer for protecting your beautiful smile after treatment.

How Do X-rays Work?

Traditional X-rays, or radiographs, make use of film just like traditional cameras. When you have an intraoral X-ray, for example, the film is sealed in a moisture- and light-proof packet, and placed inside the mouth to capture images of specific teeth and the bone around them.

The X-ray machine is aligned precisely with the film and an exposure is taken. The image at this point is latent, and won’t show on the film, because, just like photo film, traditional radiographs need to be chemically processed before they produce a visible image.

Digital technology, on the other hand, uses an electronic sensor instead of film. For an intraoral digital X-ray, a small sensor is positioned in the mouth just like a film. When the X-ray is taken, a digital image capture device produces an image which is formed by a matrix of pixels instead of a photo-like film exposure. This format allows the image to be sent directly to a computer for immediate display without requiring processing.

Even though these methods seem very similar, digital X-rays offer some significant advantages over traditional films. Let’s look at how they compare, more or less.

• More Diagnostic Advantages

A traditional X-ray is a fixed image. It cannot be modified or enhanced. Here the digital X-ray offers a clear advantage in evaluating your teeth and the bone structure surrounding them.

Just as you can enlarge certain types of images on your computer without blurring or losing detail, a digital X-ray uses computer software to magnify images while keeping their details sharp. They can also be enhanced through brightness and contrast applications to make details stand out even more.

There is even digital subtraction radiography software available that can be used to compare recent images to older ones, removing (“subtracting”) all the similarities in the two images to display only the changes in the two—even small changes—that have taken place over time.

• Less Exposure to Radiation

Modern technology means traditional X-rays expose patients to less radiation than ever before, but digital X-rays have significant advantages here as well. Radiation exposure can be reduced by an additional 10%, 20%, or more with a digital radiograph.

And while all types of dental X-rays expose you to very little radiation, it’s always best to reduce exposure whenever possible.

• More Convenient for Sharing and Transmitting

If you need to share your X-rays with another dentist or physician, digital technology allows you to simply have them e-mailed to another office or multiple offices. You no longer need to worry about preserving physical copies, either.

• Less Waste

Unlike traditional X-rays, digital X-rays don’t need to be processed, so you save time in the office. And while the processing time is not significant (usually several minutes), if you need to repeat some X-rays for a clearer picture, or require different images for several teeth, this time can add up.

Digital X-rays are also more eco-friendly.  The fact that they don’t need to be developed means that the chemicals used to process traditional films are no longer necessary—which also means that there is no need to dispose of chemical waste products afterward.

Orthodontists and dentists use advanced procedures to treat and save teeth. But sometimes, a tooth just can’t be saved and needs to be extracted. Sometimes it’s due to extensive decay, or infection, or serious injury. Or sometimes, to create a healthy bite, an extraction is necessary during orthodontic treatment.

When does an orthodontist recommend an extraction? Conditions which call for extraction include:

• Incoming Wisdom Teeth

Not many people have enough space in their mouths for four wisdom teeth! And when there’s no room to erupt properly, wisdom teeth can become decayed or infected, push your other teeth out of place, and damage the roots of nearby molars. Extracting wisdom teeth protects your teeth and your bite alignment.

Usually, orthodontic treatment takes place before the wisdom teeth begin to erupt. But if yours start to make an appearance during treatment, your orthodontist and dentist will work together to schedule extraction without interfering too much with your orthodontic treatment plan.

• Tooth and Jaw Structure

Drs. Chen and Sepe and the team at Chan & Chen Orthodontics carefully plan your treatment based on examinations, X-rays, and/or 3D imaging. The goal is to align your teeth and jaws for an attractive smile and a healthy, functional bite. When overcrowding is severe, or if there is a serious malocclusion (bite problem), or if a particular tooth is unusually large or misshapen, your orthodontist might recommend an extraction.

Sometimes more room can be made for teeth with appliances such as palatal expanders or, in other cases, with the help of oral surgery. Extractions are only recommended when they are absolutely necessary.

• Baby Teeth Which Aren’t Coming Out 

Baby teeth normally fall out in a predictable pattern. Front teeth first, canines and molars last. Baby teeth have small roots, and these roots begin to break down when the adult teeth underneath put pressure on them as they start to erupt. As the root gets smaller and smaller, the baby tooth gets looser and looser—until it falls out. 

Sometimes, though, the roots of primary teeth don’t break down, and the baby teeth stay right where they are. This means that the permanent teeth have to erupt someplace else—usually behind those baby teeth. This creates a double row of teeth, and your permanent teeth can become crooked or overlap as they try to fit in. Extracting stubborn baby teeth allows your adult teeth to come in just where they’re supposed to. Because of their small roots, extracting primary teeth is usually simple and straightforward, and can be done in your dentist’s office. 

• Too Many Teeth

Most of us have 32 adult teeth, including wisdom teeth. It’s rare, but sometimes an extra, or supernumerary, tooth develops. Your jaw is most probably not equipped to accommodate any extras, so, in this case, the extra tooth or teeth are removed to give the rest of the teeth the space they need to avoid overlapping or crowding.

When your orthodontist recommends an extraction, it’s because it’s important for your dental health. Drs. Chen and Sepe will refer you to a dentist or a specialist like a periodontist or oral surgeon, who will: 

• discuss the extraction procedure with you, including sedation options
• numb the area 
• gently loosen and then extract the tooth
• provide options for pain management after the procedure
• give you detailed instructions for aftercare
• work with your orthodontist to keep your treatment on schedule

Extraction is never your first choice, or your orthodontist’s! But when an extraction is necessary for tooth and bite alignment, everyone at Chan & Chen Orthodontics in Andover will coordinate a treatment plan to create your best—and healthiest—smile.

Braces and aligners help straighten teeth and create a confident, attractive smile. And those visible benefits are amazing! But orthodontic treatment has an even more important purpose than transforming the appearance of your smile—and that’s protecting and improving your oral health. 

If you’re ready for orthodontic treatment, you know you can look forward to a future of beaming smiles. You can also look forward to healthier teeth and gums and a more comfortable and functional bite. For some people, orthodontic treatment can make speaking and eating easier, and could even contribute to a better night’s sleep.

How can orthodontic treatment from Drs. Chen and Sepe accomplish these goals? Let’s set the record straight!

Protecting Tooth and Gum Health

• Lowering Your Risk of Cavities

Perfectly aligned teeth are considered aesthetically pleasing, but there’s a more practical reason to appreciate straight teeth. Crooked and overlapping teeth make it easier for food particles and plaque to stick in between the teeth and harder for your brush to remove them. Straight teeth allow you to remove cavity-causing plaque more effectively and with less effort.

• Promoting Healthy Gums

When plaque and tartar build up around the gums, the gum tissue becomes irritated, which is the first stage of gum disease. When teeth are straight and evenly spaced, brushing and flossing are easier and more effective, and your gums reap the benefits.

Creating a More Functional and Comfortable Bite

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when you close your mouth. There are different types of bite problems, and these can impact both your oral health and your overall health depending on the type and the severity of the malocclusion. Once a malocclusion is corrected, patients can experience:

• Stronger Teeth and Healthier Gums

Teeth and jaws which don’t fit together properly put extra pressure on your teeth and gums, leading to problems such as worn enamel, cracked teeth, and gum recession. Protect your oral health by creating a well-aligned bite.

• A Pain-Free Bite

Left untreated, malocclusions can cause problems like temporomandibular joint disorder (TMD), headaches, face and neck pain, earaches, limited jaw movement, and painful chewing. Correcting your bite will protect your temporomandibular joint from harm and will relieve the discomfort and pain caused by a malocclusion. 

Other Possible Benefits of Treatment

For those with more serious malocclusions, orthodontic treatment might improve daily life in unexpected ways:

• Improved Speech

It takes a lot of coordination to produce different sounds. The lips, the tongue, the alveolar ridge which holds our teeth, the hard and soft palates, parts of the throat, and, yes, the teeth all play a part in creating speech. Some kinds of malocclusions contribute to speech disorders such as lisps, which orthodontic treatment can help correct.

• Improved Digestion

Digestion starts in the mouth, not the stomach! As we chew, we break down our food into particles which are easier for the stomach to digest. If you can’t chew properly because your teeth are misaligned or a bad bite makes it too painful to chew food as thoroughly as you should, you won’t be getting the full nutritional benefits of your healthy diet. Orthodontic treatment helps you bite down painlessly and break down foods easily for better digestion.

• Improved Sleep

Bite problems can sometimes lead to sleepless nights. More serious malocclusions may cause mouth breathing, which, in turn, can affect the quality of your sleep. If you’re having trouble sleeping, a sleep specialist can help you discover the source of your problems. If your troubled sleep is caused by tooth or jaw misalignment, orthodontic treatment might be the solution.

Orthodontists offer many treatment options designed to align your teeth and jaws for a healthy, attractive smile. Braces or aligners might be all you need to correct a mild malocclusion. Appliances and headgear can influence the growth and position of the jaw if needed. In more severe cases, surgery, together with braces, can create a proportional, healthy bite. 

Whether it’s a confident smile, healthier teeth and gums, a functional, comfortable bite, or any of the other benefits orthodontic treatment can bring, talk to the dental team at Chan & Chen Orthodontics in Andover to discover how orthodontic treatment can help you achieve all of your smile goals!
