Even with the best of care, accidents can happen, and your retainer, unfortunately, is not immune. Of course, you need to visit our Halifax office ASAP if your retainer is damaged, but, in the meantime, there are some strategies you can use to help your teeth—and your retainer—stay as healthy as possible while you wait.

For Removable Retainers

• When you notice any damage to your removable retainer—remove it.

Don’t wear a damaged retainer, especially overnight. You don’t want to damage it further, and you do want to avoid the possibility of choking if a retainer breaks while you’re sleeping. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and our orthodontic team are experts when it comes to deciding if your retainer is wearable, so always consult an expert before putting a suspect retainer back in your mouth.

• Damaged Hawley retainer?

If you have a Hawley retainer—the traditional wire retainer—here’s some good news: a Hawley retainer can often be repaired if it’s not damaged too badly. Don’t try to fix your retainer yourself, and bring it into our office as soon as possible to see if it’s fixable.

• Damaged clear retainer?

If you have a clear retainer, let’s start with the bad news: A clear retainer is not a repairable retainer. Cracks, breaks, warping—these injuries mean that a new retainer is in your future.

The good news is that materials for plastic retainers are available that are more durable than ever. This might be a good option for you to check out, especially if you suffer from bruxism, or tooth grinding, which can be very hard on clear retainers.

• When you’ve just finished treatment with clear aligners . . .

It’s worth asking if your last tray can sub for your retainer until you have it repaired or replaced.

• Ask us about over-the-counter mouthguards.

While you wait for a retainer repair/replacement, your teeth are at risk of shifting out of alignment. A customizable OTC mouthguard might reduce the chance of shifting, although it’s definitely not a long-term solution! We can let you know if this temporary fix is worth it.

For Fixed Retainers

If the wire retainer bonded to your teeth becomes loose, or if you notice your teeth shifting, you might need a repair or a replacement. This is a job for us. In the meantime,

• When you have a broken wire . . .

If a broken wire is causing discomfort, check to see if you should flatten it or cover the wire tip with dental wax to protect soft tissues. Warm water rinses can ease irritation.

• When your wire is broken or loose . . .

Stay away from chewy, sticky, and crunchy foods. You should be doing this anyway with a fixed retainer to keep it from becoming detached—and if it’s already loose, no need to make it more so!

• Ask us about over-the-counter mouthguards.

Check to see if an OTC, customizable mouthguard is a good idea to keep your teeth from shifting if you can’t visit Metro Orthodontic Specialists right away.

We started off by saying that accidents can happen even with the best of care. So you can imagine what can happen without the best of care. Keep your retainer in its case, keep it away from heat, don’t eat foods that can harm your retainer—all the precautions that make accidents unlikely to happen.

But if something awful befalls your retainer, call our Halifax office right away. Why aren’t we suggesting ways to fix your broken retainer with the supplies you have in your home toolbox? Because the best life hack of all for someone with a damaged retainer is to leave the fixing to a dental professional.

Bite problems are so common that most of us know someone who’s worn braces. So perhaps you’re already familiar with the terms “overbite” and “underbite”—but if you’ve been diagnosed with an “overjet,” that just might be an orthodontic diagnosis that is new to you. If so, here are a few questions and answers to help promote overjet understanding.

Just what is an “overjet”?

An overjet is a type of malocclusion, which means that there’s a problem with your bite, the way your jaws and teeth fit together when you bite down. In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.”

An overjet is a Class II malocclusion, which means that the upper front teeth project further beyond the lower teeth than they should. Overjets and overbites are both Class II malocclusions, and the words are often used interchangeably, but there’s a notable difference between the two conditions.

An overbite occurs when the top teeth overlap the bottom teeth too far vertically, and you can’t see as much of the lower teeth as you should when you bite down.

An overjet is considered more horizontal in nature, where the top teeth project at an outward angle toward the lips instead of pointing straight down toward the bottom teeth. This condition is sometimes called protruding or buck teeth.

What causes an overjet?

The reason for your overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both.

Overjets can run in families. They can also be caused by the size and position of your jaws and the shape and position of your teeth, all of which affect your bite alignment. But early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to overjet development.

How do we treat an overjet?

There are many types of treatment available. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will recommend a treatment plan based on the cause and severity of your overjet. Because some treatments are effective while bones are still growing, age plays a part as well.

• Braces and Aligners

If you have a mild overjet, and minor dental issues are the main cause of the malocclusion, braces or clear aligners can effective.

• Functional Appliances

If the overjet is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still forming.

For young patients, there are several appliances which can help correct an overjet. Some, such as the Twin Block and the Forsus Spring appliances, work inside the mouth, while others, like headgear, are worn externally. Your orthodontist will recommend the most effective appliance for your needs.

• Surgical treatment

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself.

If we recommend surgery, oral and maxillofacial surgeons are experts in surgical procedures designed to create a healthy and symmetrical jaw alignment. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will work with your surgeon to design a treatment plan, which will usually include braces or other appliances following surgery.

Why treat your overjet?

A serious, moderate, or even mild overjet can lead to many dental and medical problems, including:

• Concerns about facial and dental appearance
• Front teeth which are more at risk for injury
• Difficulty closing the lips
• Problems speaking or chewing
• Headaches, facial, and temporomandibular (jaw) joint pain

When you work with our Halifax team to correct your overjet, you’re not just correcting a problem. You’re also creating something—a healthy, comfortable bite, and an attractive, confident smile. We can talk about general answers to your overjet questions, but when it comes to understanding your very individual smile, Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will have all the answers you need to make that healthy bite and that confident smile a reality! 

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.

You’ve worked hard for your attractive, healthy smile, and now you’re making sure it stays attractive and healthy by wearing your retainer. Since wearing a retainer is usually a matter of years, not months, it’s natural to wonder just how long you can count on that retainer to help you maintain your smile.

That answer depends on the type of retainer you get at our Halifax office. A Hawley retainer, a clear retainer, and a fixed wire retainer have different lifespans. Because they each have their own advantages, Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will recommend the retainer that’s right for protecting your individual smile.

So let’s look at the average lifespan for different retainers, and, equally important, some of the common mishaps that can shorten that working life.

The Hawley Retainer

This is the retainer most people picture when they think “retainer.” Made of wire securely attached to an acrylic base, the Hawley retainer keeps the teeth in place, and can even be adjusted, if needed, to improve alignment. They generally last anywhere from three to ten years.

How can you make sure your Hawley retainer keeps working for you as long as possible?

• Keep it in its case. While some damages to these retainers can be repaired, why take a chance? And it’s much harder to lose a retainer if it’s in its case as opposed to, say, a cafeteria napkin.
• Keep it away from your pet. Dogs, especially, are tempted by the taste and smell of saliva, but there are safer, less expensive chew toys out there.
• Keep wearing it. Without your retainer, your teeth can shift. Over time, not only will your retainer fail to fit anymore, but you might need to return for further orthodontic treatment. If you notice your retainer is starting to feel uncomfortable, give your orthodontist a call.

The Clear Retainer

Clear retainers look like clear aligners, and, like clear aligners, are almost invisible. Made of vacuum-formed plastic, they’re designed for a close, comfortable fit, often around the entire arch of your teeth. Also like clear aligners, these retainers aren’t made to last forever. If they become loose, warped, or cracked, they should be replaced. With care, they can last from six months to several years. How to protect them?

• Protect your retainer from damage. Keep it in its case when you’re not wearing it. You’ll avoid losing it, and you’ll avoid damaging it.
• Protect it from teeth. And we don’t just mean pets, although they find clear retainers yummy, too. If you grind your teeth, your retainer can suffer. Clear retainers are not the same thing as night guards, so talk to your orthodontist for recommendations.
• Protect it from heat. Hot surfaces like ovens or heaters, hot dashboards, washers and dryers, even very hot drinks can be a problem. (You should only be drinking water while you wear your clear retainer, so that particular issue shouldn’t arise!)

The Fixed Retainer

A fixed retainer is a small piece of wire that is custom-fit and bonded to the back of specific teeth to prevent any movement from occurring. Because it’s bonded to the inside of the teeth, a fixed retainer is completely invisible when you speak or smile. It can last five years, ten years, and in some cases, even longer. Even though you won’t be exposing this retainer to external dangers like hungry pups or the wash-and-rinse cycle, there are still some situations to watch for:

• Watch your diet. The same sticky, crunchy, or hard foods that can damage brackets and wires can also loosen a fixed retainer.
• Watch your dental hygiene. While cleaning around a bonded retainer can be a bit challenging, not cleaning around it can result in plaque and tartar buildup—and your retainer might have to be removed to clean your teeth.
• Watch for changes. If your teeth start to shift, it could mean your retainer has detached from one or more teeth. Ask your dentist to check the retainer’s bond whenever you have a checkup.

So, how long will that retainer last? Depending on the kind of retainer you have, if you don’t keep it in its case, or if you don’t watch your diet, or if you expose it to heat, the answer is—not nearly long enough. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will give you the very best tips to keep your retainer clean, safe, and working for as long as possible. Now, it’s up to you!
