Congratulations! You’ve done the hard work necessary to create your beautiful smile! You’ve carefully completed all the steps needed to reach the end of your orthodontic journey. Well, nearly all the steps. We can’t forget that last step which will ensure that all your hard work is rewarded.

When you first began orthodontic treatment, Dr. Cronin decided on the best plan for straightening your teeth and perfecting your bite, whether you wore traditional braces, lingual braces, aligners, or other orthodontic appliances. And now that you’re finishing treatment, there’s one more option to consider—your retainer.

Why do I need a retainer?

While you’ve spent time in treatment, more has changed than just the position of your teeth. The periodontal ligament, the connective tissue that connects the teeth to the jawbone, is stretched as the teeth shift. The bone in your jaw changes, too, reforming and rebuilding around the roots of your teeth as they move to their ideal locations.

These changes happen because your braces or aligners apply gentle, constant pressure to move your teeth. When you’ve finished wearing these appliances, the pressure stops. Ligaments will try to return to their original shape, which can shift teeth back toward their old positions. And the rebuilding bone isn’t dense enough yet to stop teeth from shifting due to the normal, everyday pressures of eating, chewing, and smiling.

A retainer prevents your teeth from moving back, or “relapsing,” by giving your bones and ligaments time to stabilize and rebuild. The process takes months, so keeping your teeth in place as bones rebuild and grow denser is crucial. This is especially important for patients with more serious misalignments. Dr. Cronin will let you know which kind of retainer will be best for you and just how long you’ll need to wear your retainer.

Are there different kinds of retainers?

There are! Retainers can be removable or fixed, visible or nearly invisible, metal, plastic, or metal and plastic. Three of the most popular retainer options include:

• Hawley Retainers—the traditional removable retainer, which uses a molded acrylic plate with wires attached to keep your teeth properly aligned and to hold your retainer in place.
• Clear Plastic Retainers—a removable retainer made of custom vacuum-formed plastic, which fits over the teeth like a clear aligner.
• Fixed Retainers—a small single wire bonded to the back of specific teeth, which holds them in place and prevents any movement.

Dr. Cronin will let you know whether a removable or fixed retainer is best for making sure your teeth don’t start to relapse, and fill you in on the benefits and care of each type of retainer.

How long do I need to wear a retainer?

There’s no standard answer to this question. Just like your retainer is custom-built to fit your individual teeth, the amount of time you’ll spend in that retainer depends on your individual needs. Retainers might be worn fulltime for months or years, be worn only at night after several months of daily wear, or be worn long-term to make sure your orthodontic work lasts.

Because you’ve done the hard work already, and your beautiful, healthy smile is the result. Talk to a member of our Langley team about which retainer option will be best for making sure that this smile lasts a lifetime.

Do you ever find yourself gnawing at your nails? Nail-biting is a very common and difficult to break habit which usually has its beginnings in childhood. It can leave your fingers and nail beds red and swollen. But if you think that your nails are the only ones getting roughed up by nail-biting you'd be mistaken—so are your teeth!

According to a study by the Academy of General Dentistry, those who bite their nails, clench their teeth, or chew on pencils are at much higher risk to develop bruxism (unintentional grinding of the teeth). Bruxism can lead to tooth sensitivity, tooth loss, receding gums, headaches, and general facial pain.

Those are some nasty sounding side effects from chewing on your nails. Most nail-biting is a sign of stress or anxiety and its something you should deal with. So what steps can you take if you have a nail-biting habit?

There are several things you can do to ease up on nail-biting:

• Trim your nails shorter and/or get regular manicures – Trimming your nails shorter is an effective remedy. In so doing, they'll be less tempting and more difficult to bite on. If you also get regular manicures, you’ll be less likely to ruin the investment you’ve made in your hands and fingernails!
• Find a different kind of stress reduction – Try meditation, deep breathing, practicing qigong or yoga, or doing something that will keep your hands occupied like squeezing a stress ball or playing with a yo-yo.
• Wear a bitter-tasting nail polish – When your nails taste awful, you won't bite them! Clear or colored, it doesn't matter. This is also a helpful technique for helping children get over the habit.
• Figure out what triggers your nail-biting – Sometimes it's triggered by stress or anxiety and other times it can be a physical stressor, like having hang nails. Knowing what situations cause you to bite your nails will help you to avoid them and break the habit.
• Wear gloves or bandages on your fingers – If you've tried the steps above and they aren't working, this technique can prove effective since your fingernails won't be accessible to bite.

If you're still having trouble with nail-biting after trying these self-help steps, it's best to consult your doctor, dermatologist, or Dr. Cronin. For some, it may also be the sign of a deeper psychological or emotional problem.

Whatever the cause, nail-biting is a habit you need to break for your physical and emotional well-being. If you have any questions about the effects it can have on your oral health, please don't hesitate to ask Dr. Cronin during your next visit to our Langley office.

Clear aligners like Invisalign® have become increasingly popular over the past several years and rightly so. They’re removable, easier to clean than braces, and hardly anyone knows you're wearing them. They are great in treating many cases, but they aren't for everyone.

Below, Dr. Cronin and our team cover some of the instances where clear aligners just aren't the answer:

• If drastic tooth movement is required – Fixed appliances deliver much more significant tooth movement. So if your case is a drastic one, clear aligners may not be the best choice.
• If you need to move molars – Molars have much stronger roots than your other teeth and would require significantly longer to move with clear aligners. A fixed appliance is the best choice in this instance, especially if you have a substantial overbite or underbite that needs to be dealt with.
• If you're the type who often forgets or loses things –If you would forget to wear your aligners for the prescribed amount of time (usually at least 22 hours per day), clear aligners are probably not the best choice for you. Forgetting to wear them can delay treatment and even make it so you need to regress to the previous set of aligners to be able to move forward with treatment. And let's face it, if you're not careful, removable aligners are easy to lose. Losing aligners delays treatment and is expensive since you need to buy replacements to stay on course. Replacing a lost set of aligners usually takes between seven and ten days—a definite setback in treatment.
• If you're looking for the fastest treatment possible – Clear aligners usually can't move teeth as quickly as fixed appliances. So if you're looking for the fastest way to achieve your desired result, clear aligners may not be the best bet.

Feel free to talk with Dr. Cronin about your options regarding braces and clear aligners. We know there are pros and cons to both, so let’s find the option that works best in your life and for your specific needs in terms of treatment. Schedule an appointment at our Langley office today!

Brackets and wires, clear aligners, lingual braces, regular brackets, self-ligating braces, elastics, spacers—you and your orthodontist have had to narrow down a lot of choices to discover the best treatment for your orthodontic needs. Now that the end of treatment is in sight, there’s one more important choice left—your retainer!

Do I Need a Retainer?

No retainer at all is probably the one option that’s off the table from the start. It’s not just your teeth that have changed position; it’s the bone and ligaments holding them that have changed as well.

A retainer prevents your teeth from moving away from their new, ideal location while your bones and ligaments are stabilizing. This process takes months, so keeping your teeth in place as your bone rebuilds and regains density is crucial.

What Are Your Retainer Options?

Three of the most popular retainer options available at our Langley office include:

• Hawley Retainers

This is the traditional retainer, with wires to hold your retainer in place and to keep the teeth properly aligned. The wires are attached to an acrylic plate molded to fit the roof of your mouth or around your bottom teeth. You can customize the acrylic base with colors and patterns for a one-of-a-kind look.

Hawley retainers are adjustable, so minor realignments can take place if necessary. The wire in front of your teeth makes these retainers visible, but, after several months of wearing them all day long, you may end up wearing them only at night.

Hawley retainers are removable, so you need to make sure they are safely in a case when you’re not wearing them. Minor damage can often be repaired, but it’s better to be proactive.

• Clear Plastic Retainers

These retainers look like clear aligners. They are formed by heating a thin piece of plastic and vacuum-forming it around a model of your teeth to create a custom, comfortable fit.

Clear retainers are almost invisible when worn, and can be removed when you eat or drink—which they should be, because food particles and liquids can be trapped inside them.

When you’re not wearing it, a clear retainer should always be in its case, because it must be replaced if the plastic is warped, cracked, or broken.

• Fixed Retainers

A fixed retainer is a small single wire bonded to the back of specific teeth, commonly the six bottom front teeth. Because fixed retainers don’t allow the teeth to move at all, they are often recommended for patients who had serious misalignments, extremely crowded teeth, or teeth with large gaps between them.

Many patients like fixed retainers because they keep teeth in perfect alignment, they won’t be seen, they’re comfortably small, and they can’t end up in the cafeteria recycling bin because you forget to replace them after lunch!

Fixed retainers are usually quite durable, but you’ll need to pay attention to your diet, because crunchy and chewy foods can put pressure on the retainer and damage it. These retainers also require special care with brushing and flossing, to make sure the teeth bonded to the wire stay clean and plaque-free.

The Right Retainer

The process of stabilizing your teeth in the jaw takes time. Choosing your retainer will depend in part on how long and how often you need to wear it: fulltime for months or for years, at night after several months of day-and-night wear, or long-term to make sure your orthodontic work lasts.

And there are other variables, as well. Your retainer might need to be removable. It might need to be adjustable. You might need a retainer for just your upper teeth, just your lower teeth, or both. All these factors and more need to be taken into consideration before deciding on your ideal retainer.

Fixed, removable, wire, plastic, colorful, clear—which retainer is right for you? The one that helps you retain the beautiful smile you’ve worked for all these months. Talk to Dr. Cronin to discover the retainer that will protect that smile for years to come.
