As you near the end of your orthodontic treatment, you’re probably already imagining the day when your brackets and wires finally come off. Or the moment you’ve finished with your last set of aligners. That day might come just a bit sooner if Dr. Daniel Ma and our team recommend a positioner.

While not as well-known as other orthodontic treatments, a positioner is an appliance that can shorten your time in traditional braces and aligners by weeks or even months. Curious? Read on!

• What Exactly Is a Positioner?

A positioner resembles a clear mouthguard. Its arched shape is designed to fit snugly over your teeth. It’s sometimes called a finishing appliance, because it’s designed to make those last small adjustments to your alignment and bite. If you’re a good candidate for a positioner, it can replace your braces or aligners for your last several weeks or months of treatment.

• How Are Positioners Made?

This appliance is custom fabricated to fit your very specific orthodontic needs. Commonly, a mold is made of your teeth. A model of your teeth is made from this mold. Precision instruments are used to move the model teeth into your ideal alignment.

Once this model of your future finished smile is complete, it is used to create the positioner. When the thermoplastic material is molded to the model, it creates an appliance with an indentation for each individual tooth in its desired final location.

Available in a variety of materials, a positioner is most often designed as a clear single piece, covering both your upper and lower teeth. This makes sure that your teeth are not only aligned properly, but that your upper and lower teeth are working together for a healthy bite. Openings in the positioner provide airways which allow you to breathe easily.

• How Do Positioners Work?

Because your teeth haven’t settled firmly into place yet (this will happen as you wear your retainer), they’re still able to move. That’s why your positioner is shaped to fit your teeth in their future ideal placement, not where they are at present.

Positioners require your active participation. Your teeth move to the ideal spots molded into the positioner through “exercise”—biting down on your appliance for 15-20 seconds before relaxing your bite, usually every 10-15 minutes during your daily wear. The gentle force provided by your jaw muscles helps guide your teeth into position more quickly. Dr. Daniel Ma will give you instructions on just how to—and how often to—do these exercises.

• How Long Are They Worn?

Positioners are commonly worn at least four hours a day to start with and all night long, or Dr. Daniel Ma might recommend 24 hour a day wear for the first week. As you progress, you’ll wear them for shorter periods during the day, gradually tapering off until your treatment is complete.

Depending on the amount of correction that’s still needed, positioner use ranges from several weeks to several months. One thing that will ensure that your time in a positioner is as short as it can be is your willingness to follow our instructions. The speed and effectiveness of your final tooth movements is largely up to you!

• Caring for a Positioner

Gentle treatment is best. Clean your positioner before and after wearing it using a toothbrush and mild toothpaste. Never boil it or expose it to heat. We will give you instructions for how to clean it more thoroughly, if needed.

Like retainers, clear aligners, and mouthguards, a positioner needs to be protected when it’s not in your mouth. Your positioner will come with a case, so be sure to use it!

Positioners aren’t recommended for every orthodontic patient. But if you feel this might be an option worth pursuing, talk to us when you visit our Vancouver, BC office. A positioner could be an effective, time-saving step on your path to a lifetime of healthy smiles.

Somewhere in a bathroom drawer or medicine cabinet, we all have one—that little plastic dental floss dispenser. And whether you use your floss every day (yay!), or have completely forgotten it was in there (not so good), just how much do you know about that sturdy string? Let’s find out!

• Flossing has been around for hundreds of years.

FACT: It’s been just over two hundred years since Dr. Levi Spear Parmly, a dentist in New Orleans, suggested his patients use waxed silk thread to clean between their teeth. This is considered the first “official” invention of dental floss, although using some form of tool to get rid of food particles between the teeth has been around since prehistoric times.

• Brushing well is the same as flossing.

FICTION: It’s really not. While brushing does a great job of cleaning food particles, plaque, and bacteria from your enamel, there are some places those bristles can’t… quite… reach. Floss was designed to clean plaque and food from between the teeth and close to the gum line where your brush doesn’t fit.

• There’s more than one way to clean between your teeth.

FACT: Indeed there is! Not only are there many varieties of dental floss (waxed, flavored, round, flat, thick, thin, in a dispenser, attached to miniature floss wands), but you have alternatives if using any kind of floss is difficult for you. Water-flossers direct a pulsing stream of water between and around the teeth and gum line to remove food particles and plaque. Another useful alternative is the interproximal brush, a tiny little cone-shaped brush designed to remove food and plaque from those hard-to-reach spots.

• It’s impossible to floss with braces.

FICTION: Untrue—but it can be more challenging! That’s why there are any number of flossing products designed to work with and around your braces. Stiff strands of floss which work like dental picks, floss threaders, water flossers, and interproximal/interdental brushes can both clean between your teeth and remove food particles and plaque where they collect around your braces. Dr. Daniel Ma can suggest some great options to work with your individual orthodontic treatment.

• Flossing helps prevent gum disease.

FACT: Scientific studies haven’t provided definitive answers. But dental and periodontal associations strongly recommend daily flossing as one of the most important things you can do to prevent gum disease. Gingivitis, or mild gum disease, is caused by irritated, inflamed gum tissue. Gum tissue becomes irritated and inflamed as a response to the bacteria, plaque, and tartar that stick to your teeth. Anything you can do to help remove these irritants will reduce your risk of gum disease.

• Flossing helps prevent cavities.

FACT: Dentists strongly recommend daily flossing to remove the food particles and plaque that lead to cavities. Brushing removes cavity-causing plaque from the outer surfaces of your teeth. But there’s a lot of enamel between your teeth as well. Flossing removes plaque from these hidden spots, helping to prevent interproximal (“between the teeth”) cavities from forming.

• Bleeding when you floss is normal.

FICTION: Bleeding isn’t a typical reaction to flossing. Bleeding gums could be an early sign of gum disease caused by plaque and tartar buildup. On the other hand, if you floss too hard, or go too deeply below the gum line, you can make delicate gum tissue bleed. Ask Dr. Daniel Ma for tips on perfect flossing technique.

• You need to floss after every meal.

FICTION: Dental professionals generally recommend brushing twice a day and flossing at least once each day. But this suggestion comes with some exceptions. Since you have braces, Dr. Daniel Ma might recommend flossing whenever you have a meal or snack.

• Your dentist will never know that you haven’t been flossing.

FICTION: Nope. Sure, you can miss flossing a few times and catch up before your appointment at our Vancouver, BC office. But built-up plaque between the teeth, red, swollen, or bleeding gums, and gingivitis and interproximal cavities let both you and your dentist know that you’ve been neglecting good dental habits.

• It’s never too late to start flossing!

FACT: Flossing is a simple, quick, and inexpensive way to maintain tooth and gum health. If you haven’t had much luck flossing in the past, ask Dr. Daniel Ma for flossing tools and techniques that will work for your specific needs. Start now, and see what a difference it will make at your next checkup!

If you had all these flossing facts at your fingertips, congratulations! But if you didn’t, no need to worry, because the real test of your knowledge is in its application. Flossing properly at least once each day will give you something far more rewarding than blog-quiz kudos—you’ll see that regular flossing rewarded with healthier teeth and gums!

When we think orthodontics, we commonly think teeth. Naturally! Straight teeth and a beaming smile are everyone’s orthodontic goal. But orthodontics is a field which specializes in more than misaligned teeth. While your beautifully aligned teeth are the visible outcome of your orthodontic work, a properly aligned bite is the foundation for your healthy smile.

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when the mouth is closed. A malocclusion, or bad bite, affects many people to some degree, but not always in exactly the same way. Some of the different types of malocclusion include:

• Crossbite

A crossbite occurs when upper teeth fit inside lower teeth. An anterior crossbite refers to the front teeth, with one or more upper front teeth, or incisors, fitting behind lower front teeth. A posterior crossbite affects the back teeth, with upper teeth fitting inside the lower teeth on one or both sides of the jaw.

• Crowding

When the jaw is small and/or the teeth are large, lack of space can result in crowded, twisted, or crooked teeth.

• Open bite

An anterior open bite means that the front teeth don’t close when biting down, leaving an open space between the upper and lower teeth. A posterior open bite occurs when the back teeth don’t make contact when the front teeth close.

• Overbite

Our upper front teeth naturally overlap the lower ones a small bit when the teeth are closed. An overbite occurs when the upper teeth significantly overlap the lower teeth.

• Overjet

When the upper front teeth protrude too far forward over the bottom teeth, it’s called an overjet, or, sometimes, buck teeth. Where an overbite causes a vertical overlap, an overjet takes into account the horizontal relationship of the teeth.

• Spacing

A jaw that is large, teeth that are small, missing teeth—these conditions can lead to gaps between the teeth.

• Underbite

An underbite results when the lower teeth and jaw extend further forward than the upper teeth and jaw, causing the bottom teeth to overlap the top teeth.

If you have a malocclusion, what comes next? This depends.

Some malocclusions are so minor that no treatment is necessary. Some are the result of misaligned teeth. Some occur because the upper and lower jaws are growing at different rates. Some are a combination of teeth and jaw misalignments. Some are caused by genetics, while others are caused by injuries or habits like prolonged thumb sucking or tongue thrusting.

Because malocclusions are so varied, your treatment plan will be designed for your specific needs. Braces, aligners, appliances like the Herbst® appliance or the palatal expander, surgery for severe malocclusions—there is a larger variety of treatment options than ever before to help you achieve a healthy bite.

When teeth and jaws don’t fit together as they should, the consequences can be damaged teeth and enamel, problems with the temporomandibular joint, headaches and facial pain, and difficulty chewing, eating, and speaking.

The good news is that early intervention for children can help correct teeth and jaw problems before they become more serious, leading to easier orthodontic care in the teen years, and helping to avoid the possibility of surgery or extractions. This is why Dr. Daniel Ma and our team recommend an orthodontic assessment at our Vancouver, BC office for children around the age of seven.

If you’re an adult with concerns about your teeth or bite, there’s good news for you, too. Dr. Daniel Ma can devise a treatment plan to improve your bite and your smile no matter what your age.

Of course, despite our title, there’s really no such thing as a “common malocclusion” when we’re talking about your dental health. Each person—and each smile—is unique. Dr. Daniel Ma will diagnose your malocclusion and create a personalized plan carefully tailored to your exact needs, for an uncommonly attractive, confident, and healthy smile.
