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!

You’ve decided—now’s the time to talk to Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard about straighter teeth and a better bite. So what’s holding you back? If you are concerned because you have a missing tooth, don’t let that stop you from making that first appointment. Orthodontists today have many options to help you achieve the benefits of a more attractive, and even healthier, smile.

How can we accommodate a patient with a missing tooth or teeth? Because each patient is different, our approach will be tailored to your specific needs.

A Lost or Missing Permanent Tooth

There are a number of treatment options available, depending on the position of your other teeth.

• If your teeth are already crowded, it might be possible to close a small gap left by a missing tooth with braces.
• If the space between your teeth is the perfect size for a replacement tooth, your orthodontic appliance will keep that spot open as your braces move the rest of the teeth into alignment.
• If you need more space for a replacement tooth, braces can help widen the space between your surrounding teeth for an ideal fit.

Tooth loss can occur for a number of reasons. Accidents, decay, and gum disease can lead to tooth loss.  Congenitally missing teeth, teeth that simple never developed, are also a fairly common condition. But missing teeth are not merely a cosmetic issue, and should not be ignored. A gap in your smile can lead to shifting of the teeth around it, bite problems, difficulty chewing, and gradual loss of bone tissue beneath the missing tooth.

Today’s implants are a permanent, natural-looking replacement for a lost tooth. If you decide that an implant is your best option for tooth replacement, you are still a candidate for orthodontic treatment. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and your oral surgeon can decide on a schedule that will provide the best timing for each phase of your treatment.

A Lost Baby Tooth

Finally, let’s not forget younger patients. Sometimes children benefit from orthodontic care before all of their adult teeth have erupted. If your child has lost a baby tooth too early, a space maintainer can be used to prevent shifting and misalignment of the remaining baby teeth and leave room for the adult tooth to erupt in its proper spot.

We recommend that your child have a first orthodontic assessment around age seven, but if your child has lost a primary tooth before its time, give our Halifax office a call. We can let you know if a space maintainer is the best way to prevent future dental and orthodontic problems.

If you have concerns about a missing tooth or teeth, talk to us! Orthodontic treatment is always custom-designed to fit the needs of each individual patient. We can discuss your specific goals, and how orthodontic treatment can help you achieve them. There is no reason to let a missing tooth keep you from a more attractive, healthier smile!

Winter and its snowball fights are behind us, true, but there might be another kind of snowball heading your way. When you neglect the small steps involved in your everyday orthodontic routines, little problems can start to snowball into bigger ones, affecting your dental health and delaying your orthodontic progress.

Here are three areas where letting the small steps in your routine slide can have consequences:

Dental Hygiene

It can be harder to get your teeth their cleanest while you’re wearing braces. After all, there are wires to get behind and brackets to brush around, and you still need to get that floss in between your teeth. But neglecting your dental hygiene can have big consequences:

• Demineralization

The bacteria in plaque create acids that strip the minerals from tooth enamel. This process is called demineralization. Wherever plaque is allowed to build up, you’ll start to see white spots in the enamel. This discoloration is a sign that minerals are missing, and is often found around brackets, where it’s harder to brush. White spots can be treated cosmetically, but better to avoid them as much as possible, because eventually they can become . . .

• Cavities

As demineralization continues, the enamel becomes weaker and weaker, until a hole forms in the tooth—a cavity. Besides damaging your tooth, a cavity can put you behind your orthodontic schedule if you need parts of your braces removed for treatment.

• Gum Disease

When plaque builds up around the gums, gum tissue becomes inflamed and irritated—this is gingivitis, or early-stage gum disease. Symptoms often include puffy gums, redness, bleeding, and bad breath. Mild gum disease becomes more serious over time, so treat gingivitis early—or, even better, prevent gum disease with careful brushing and flossing.

Looking After Your Appliances

• Follow Care Instructions

Orthodontic appliances need love, too! Any instructions you get for their care are for a good reason. Brackets can become loose when you bite down on chewy foods. Wires can break when you eat hard candy. Aligners can warp if you leave them on a hot dashboard. If you follow instructions carefully, you won’t need to postpone your progress while you wait for repairs.

• Use Your Protective Case

If you wear aligners, or a removable appliance, or a retainer, don’t forget to protect these items when you’re not wearing them. This means placing them in their cases, not wrapped in a napkin on your lunch tray, or in the bottom of your gym bag, or anywhere your dog can reach them!

• Be Proactive If Accidents Happen

Unfortunately, accidents do happen, and loose brackets, broken wires, lost ligatures, and cracked or warped aligners can interrupt orthodontic progress and cause you pain and discomfort. Give our Halifax orthodontic office a call to see if minor damage to an appliance can be handled at home, or whether you should be seen before your next regular appointment for repairs.

Following Your Orthodontic Plan

There’s more to following your orthodontic schedule than arriving on time for appointments. Depending on your treatment, you might be responsible for keeping track of the time you spend wearing:

• Elastics

Elastic bands can be used to help align your upper and lower jaws. If you don’t wear your bands as directed, you won’t make progress as quickly as you could. And remember to replace your elastics as often as recommended, because after hours of s-t-r-e-t-c-h-i-n-g they lose their effectiveness.

• Aligners

Most aligners are worn for around 22 hours each day. If you don’t follow your orthodontist’s instructions and wear your aligners for the recommend hours each day, your teeth won’t be in the proper alignment when your next set of trays is ready to begin work.

• Retainers

If you have a retainer and don’t wear it, your teeth will start to shift position. Skip wearing your retainer long enough, and you might need a return to your braces or aligners to repair any new misalignment.

Don’t ignore what seem like little dental and orthodontic responsibilities. Keep up with daily cleaning and brushing, take care of your appliances, and follow your orthodontic plan, and you’ll finish your treatment with a beautiful and healthy smile—right on schedule.

If Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and our team at Metro Orthodontic Specialists have recommended a palatal expander, you might be wondering what it is and how it will help you. A palatal expander is a small appliance fitted in your mouth to create a wider space in the upper jaw. It is often used when there is a problem with overcrowding of the teeth or when the upper and lower molars don’t fit together correctly. While it is most commonly used in children, some teens and adults may also need a palatal expander.

Reasons to get a palatal expander

There are several reasons you might need to get a palatal expander:

• Insufficient room for permanent teeth currently erupting
• Insufficient space for permanent teeth still developing which might need extraction in the future
• A back crossbite with a narrow upper arch
• A front crossbite with a narrow upper arch

How long will you need the palatal expander?

On average, patients have the palatal expander for four to seven months, although this is based on the individual and the amount of correction needed. Several months are needed to allow the bone to form and move to the desired width. It is not removable and must remain in the mouth for the entire time.

Does it prevent the necessity for braces?

The palatal expander doesn’t necessarily remove the need for braces in the future, but it can in some cases. Some people only need braces because of a crossbite or overcrowding of the teeth, which a palatal expander can help correct during childhood, when teeth are just beginning to erupt. However, others may eventually need braces if, once all their permanent teeth come in, they have grown in crookedly or with additional spaces between.
