Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth that sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity that develops on one of those side surfaces of your teeth.

• Preventing Interproximal Cavities

Fortunately, prevention is about as basic as it can be—brushing and flossing effectively. Dentists recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gum line—places where bristles just can’t reach.

When you wear braces, though, flossing isn’t quite so basic. Getting that floss just where it needs to be in between brackets and wires and in between teeth can be a challenge!

The good news is there are many products designed just to make flossing easier while you’re in orthodontic treatment:

• Floss threaders are flexible hoops that help you thread floss behind your wires easily.
• Precut floss strands use a stiff tip at one end for threading floss through wires.
• Interproximal brushes are tiny, cone-shaped brushes which can fit between your teeth and braces for precise cleaning.
• Water flossers eliminate floss altogether, using a pulsing stream of water to clean between and around teeth and braces.

During your next visit to our Halifax office, Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard can give you tips on how to use any of these tools effectively for cleaner teeth and cleaner braces.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If we find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with your dental team to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

There are so many adults and teens in our Halifax office who would love to have their teeth straightened but that are unwilling to go through the long and unsightly process of traditional metal braces. Well, that's where Invisalign® and Invisalign Teen® come to the rescue; the most advanced clear aligner systems in the world!

There are several reasons why, if you're considering getting braces, you should consider Invisalign too. Here are some of them:

• You can eat whatever food you'd like, without worrying about it getting caught in wires or breaking brackets.
• Most people won't even know you're wearing them!
• If you need to, you can remove your aligners at any time.
• The removable aligners let you brush and floss as you normally would, making for better overall oral health.
• Since they are made of a smooth BPA-free plastic, Invisalign aligners are simply more comfortable to wear than traditional braces. No metal means no more roughed up gums or irritated tongue!
• You'll need to visit our Halifax office less often — only once every six weeks or so.
• With Invisalign Teen, you’ll receive up to six replacements for lost or broken aligners.

Before you get started with treatment, you’ll have a consultation with Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard to see if Invisalign or Invisalign Teen is right for you. If your case is a good fit, then you’ll have X-rays, pictures, and impressions of your teeth taken. That information will be used to make the 3D models of your teeth that let Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard see how they will move throughout the entire treatment and approximately how long it will take.

After that, you’ll receive your aligners based on the treatment plan we recommend. You’ll get a new set of aligners every two weeks. Then all you need to do is wear your aligners 22 hours a day and you’ll be on your way to a straighter healthier smile. Don’t hesitate to a member of our Halifax team for more information about Invisalign!

By and large, the human body is a marvel of symmetry. But, of course, no one is perfect. You might have noticed one ear is a bit higher than the other. That you wear a shoe a half-size bigger on your left foot. That one shirtsleeve always looks longer.

Or that your smile looks off-center. This dental asymmetry could be caused by a condition known as “midline misalignment,” and, unlike that left foot, you can do something about it!

The dividing line between our center teeth, upper and lower, is called the midline. If we draw an imaginary line down the middle of a face, from the forehead to the nose to the midpoint of the chin, that line should go right between the front teeth. When it doesn’t, because the teeth have shifted past the midpoint, it’s often due to a condition called midline misalignment.

This kind of misalignment, also known as a deviated midline, can have several causes:

• Baby teeth that are lost too early

Baby teeth do more than promote healthy eating and speech development. They also reserve space for permanent teeth. If a primary tooth is lost too early, permanent teeth might “drift” to fill the empty space, causing the midline to move as well.

• Thumb sucking that goes on too long

As a child gets older, and certainly when by the time permanent teeth start to arrive, aggressive thumb sucking can lead to numerous orthodontic problems, including a deviated midline, as the teeth shift in response to that continuous pressure.

• Missing adult teeth

When you lose a tooth through decay or trauma, or when an adult tooth simply never develops, the remaining teeth can shift over to fill the open spot.

• Spacing issues

Crowded teeth, teeth with significant gaps between them, very large teeth, very small teeth—all of these issues can affect spacing and midline alignment.

• Crossbite

A crossbite is a kind of malocclusion, or bite problem. When you have a crossbite, the teeth don’t fit together properly, with upper teeth fitting inside lower teeth, instead of aligning on the outside where they belong. A deviated midline can indicate a posterior crossbite, where the top back teeth slant inwards or fit inside the bottom back teeth.

A tiny bit of midline shift one way or the other might be nothing to worry about, but if one front tooth is literally the center of attention, or if your teeth are noticeably out of alignment, it’s a good idea to talk to our Halifax orthodontic team.

Because there are several potential causes for midline misalignment, Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will carefully analyze your individual situation to determine where the problem lies: with the teeth, the bite, or, rarely, the jaw itself.

Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will also offer you your best dental treatment options. A shift of a few millimeters might be treated with clear aligners or traditional braces. A crossbite could require braces or aligners coupled with elastics (rubber bands) to bring your bite into alignment. A palatal expander can help correct a serious crossbite.

Why visit Metro Orthodontic Specialists because of a little asymmetry? Because a deviated midline is more than a cosmetic concern. If you have a malocclusion to begin with, or if your misalignment leads to changes in chewing habits, which cause new bite problems, you might be facing jaw pain, chipped and cracked teeth, headaches, and all the other unpleasant consequences of malocclusion.

By and large, perfect symmetry in life is unattainable. But if you want a smile that is well-balanced and healthy, talk to us about all the treatments available to make sure your smile—and not a single tooth—is the center of attention.

The iTero® Intraoral Scanner has revolutionized the way orthodontic impressions are taken. Now there's no need for messy, uncomfortable molds. Getting high-quality and accurate impressions has never been easier or more reliable.

When a patient comes to our Halifax office for a consultation, Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will need to take records of the person’s teeth and bite. Having a replica of a patient’s teeth and bite enables the orthodontist to plan out and visualize the most effective and timely treatment plan.

Traditionally, this was achieved by creating a plaster mold or cast. Putting the impression material and trays onto the teeth can be an uncomfortable process for many patients, especially those who have a sensitive gag reflex.

All that is history with iTero digital impressions. Our patients and team members alike love the speed and accuracy of the iTero Intraoral Scanner. We simply move the wand around your teeth and gums, and within seconds, you get a high-quality, accurate, and color digital impression. That’s all there is to it!

Here’s what patients love about iTero:

• There are no messy and gag-inducing molds involved.
• It’s quick, so the process doesn’t interfere with your busy schedule.
• It’s painless and can be used on even the most pain-sensitive patients.
• Impressions are saved in a digital format, so there’s no risk of molds breaking or needing to be recast.
• Cutting-edge accuracy makes for more timely, comfortable, and effective orthodontic treatment.

Our Halifax office is equipped with the latest iTero technology to make your office visit a breeze. So many aspects of our lives have been digitized and simplified, why should your orthodontic treatment be any different?

If you’re thinking about getting braces or clear aligners, iTero will optimize the experience and help ensure you get the best treatment you possibly can!
