Let’s talk science! From the vastness of the cosmos to sub-atomic particles, science helps us understand the world around us and how it works. So, let’s take some familiar scientific fields of study and apply them to your toothbrush.

My toothbrush?

Yes, indeed! When it comes to your oral health, your toothbrush is the first line of defense, so understanding how and why it works so well might help us use this handy tool even more effectively.

Biology—the study of living organisms

Unfortunately for your toothbrush, the living organisms we’re talking about here are the bacteria which cause tooth decay and those which can lead to illness. How do these problems arise, and how do we prevent them?

Fight Plaque

Plaque is the sticky film that builds up on teeth, and millions of oral bacteria help make up this biofilm. These bacteria convert sugars and other carbohydrates in the foods we eat into acids. And these acids erode our tooth enamel, leading to tooth decay. (More on this when we get to Chemistry.) The best ways to get rid of plaque?

• Brush often. The recommended minimum is two minutes of brushing twice a day, but when you’re having orthodontic work done, it’s even more important to banish the plaque that can stick to your braces or inside aligners. Ask us what brushing schedule is best for you.
• Try an electric toothbrush. For some people with braces, cleaning the teeth is easier and more thorough with an electric brush.
• Replace your brush regularly. Brushes become worn and frayed after three or four months, and you won’t be brushing as effectively.

Stop Germs from Spreading

• Don’t share. Sharing toothbrushes can lead to an increased risk of colds and infections.
• Rinse thoroughly after brushing, making sure you remove any toothpaste or debris left after you brush.
• Store the brush upright and let it air-dry. Covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.
• Keep different brushes separate when they’re drying to avoid cross-contamination.
• Replace your brush regularly!

Chemistry—the study of what makes up substances, their properties, and how they interact

When it comes to improving your brushing chemistry, the best thing you can do for your toothbrush is to put a dab of fluoride toothpaste on it! Why fluoride? Let’s look at the chemistry of tooth enamel.

Tooth enamel is the strongest substance in our bodies—even stronger than bone. But it is not indestructible, and acidic substances can dissolve the mineral bonds which give our enamel its strength, whether they come from the bacteria in plaque or are found in our favorite foods and drinks (sodas, coffee, tomatoes, and citrus are among the tasty, but acidic, culprits).

The enamel in our teeth contains calcium and phosphate ions, minerals which help make it the strongest substance in our bodies. But when the level of acidity in our mouths becomes too high, these minerals begin to dissolve. Eventually, teeth become pitted, bacteria can penetrate more deeply, and decay is the result.

So what can we do? While our saliva helps neutralize acidity naturally, and we can cut back on acidic foods in our diets, using fluoride toothpaste actually helps restore the strength of our enamel in a process known as “remineralization.”

Fluoride works on the surface of enamel to both attract and anchor calcium ions, reducing mineral loss and strengthening the weakened enamel. Fluoride also interacts with the calcium and phosphate compound to create a new compound that is even stronger and more acid-resistant.

When you brush with fluoride toothpaste, you help replace and restore the mineral composition of your enamel—and there’s evidence that fluoride might even interfere with oral bacteria’s ability to produce acid. Now that’s good chemistry!

Physics—the study of matter and energy and their interactions

The matter here is your tooth enamel, and the energy is the force you use when brushing. And this is one time the force should not be with you.

• Over-vigorous brushing can not only damage your brackets, but can also irritate delicate gum tissue and wear down enamel. A “sawing” back-and-forth motion is both hard on your enamel and misses plaque and debris between the teeth. We’ll be happy to show you the safest and most effective way to brush with braces. Just remember, “Massage, don’t scrub.”
• A soft toothbrush is almost always your best option when you use a manual brush, but if you’re still a heavy-handed brusher, or have sensitive teeth and gums, consider an electric model. An electric toothbrush should provide a continuous brushing motion without needing any heavy pressure from the brusher. Some models will even let you know when you are brushing too hard.

Brushing harder is not brushing better, and your teeth, gums, and braces will be heathier with careful brushing habits. If you need tips on brushing with braces, contact our Halifax office and ask!

There’s a lot of science in the simple act of brushing, but we don’t need to spend hours studying to get a passing grade in dental health. The things you do normally—brushing at least two minutes twice a day, using fluoride toothpaste, and applying proper brushing technique—will help create a smile which will earn you top marks from Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard for a lifetime!

If you have been thinking about undergoing orthodontic treatment to straighten teeth or correct jaw alignment, the first step is scheduling an orthodontic consultation at Metro Orthodontic Specialists. During the consultation we will actively listen to your concerns and address all of your questions, as well as discuss a treatment options that would best suit you or your child's situation.

Here are the top five questions that most patients want answered during their initial orthodontic consultation:

• Can I benefit from orthodontic treatment, and if so, how long will it take?
• How frequently will my appointments be scheduled?
• Can I expect any pain when getting braces? (Ask Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard about the ways we address pain management).
• Will I need to have teeth extracted, headgear, expansion appliance, etc.?
• How much will it cost and what payment options do you offer?

Visit our website for more answers to your questions prior to your initial consultation. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and our team at Metro Orthodontic Specialists are happy to answer all your questions and concerns, and excited to explain all aspects of your treatment plan, as well as the expected outcome. We believe your orthodontic experience should be comfortable, hassle-free, and most importantly, leave you with the smile you've always wanted.

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 Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard 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.

Our goal is to provide you with the safest, most efficient, and most effective treatment possible. Digital X-rays are an important tool for orthodontists, helping us to provide you with the best treatment plan possible. If you have any questions about digital X-ray technology, contact our Halifax office. We’re happy to explain the science—and the benefits—behind this high-tech diagnostic tool.

Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and our team know most of our patients at Metro Orthodontic Specialists would probably welcome the idea of speeding up the time they wear braces. And now they can, thanks to AcceleDent, a treatment option that has been shown to increase tooth alignment by 106 percent and reduce the time you spend wearing braces, anywhere from 38 to 50 percent.

By using this pain-free, simple appliance for 20 minutes a day, you will accelerate your orthodontic treatment time using patented technology that gently vibrates the teeth and surrounding bone, allowing teeth to move more freely and creating an ideal bite faster than with braces alone.

AcceleDent is championed as a safe and comfortable option for patients of all ages. When you first begin wearing the light appliance, you may experience a small tingling sensation, much like that of an electric toothbrush, but it should diminish after you become accustomed to wearing it. You may even forget you’re wearing the appliance!
