Retainers: Preventing Shifting Teeth After Braces

So, you finally got your braces off, and now you’re smiling wider than ever. But before you get too comfortable, your orthodontist hands you something – a retainer. You might be thinking, “Wait, aren’t my teeth straight now? Why do I need this?” Well, the journey to a perfect smile doesn’t stop with braces. Retainers play a key role in keeping your teeth where they should be and preventing them from shifting back to their old positions. 

Why Teeth Shift After Braces

Your teeth may seem like they’re locked in place once the braces come off, but they’re not. Teeth naturally have a tendency to move over time, even if you’ve had them straightened. This process is called “orthodontic relapse.” After braces are removed, the ligaments and tissues around your teeth need time to adjust to their new position.

Think of it like planting a tree – the roots are fragile at first. If not supported properly, they could shift or grow in the wrong direction. It’s the same with your teeth. Without a retainer, they might start moving back to their original spots. Studies show that nearly 90% of orthodontic patients experience some level of relapse without retainers.

How to Use Retainers for Teeth

How Retainers Prevent Shifting

Retainers are like a safeguard for your newly aligned smile. Their job is to hold your teeth in place while the surrounding bone and tissues adjust.

Retainers come in different types, each working to keep your smile intact: Removable retainers (such as Hawley or clear retainers) are easy to take out for cleaning but must be worn consistently. Fixed retainers, on the other hand, are bonded to the back of your teeth and stay there indefinitely, offering constant protection against shifting.

Wearing your retainer as directed by your orthodontist is crucial during the first few months after braces, as this is the most vulnerable period for tooth movement. Skipping your retainer or only wearing it occasionally can lead to unwanted shifting, and over time, those small changes can become more noticeable.

Types of Retainers

Your orthodontist will recommend a specific type based on your needs. 

Removable Retainers: These are the most common. Hawley retainers are the classic wire-and-acrylic style, while clear retainers (like the Essix) are made of clear plastic. Both are easy to remove for cleaning and eating. While the Hawley retainer is adjustable and durable, clear retainers are more discreet but may need replacement more often.

Fixed Retainers: These are thin wires bonded to the back of your front teeth. They’re particularly useful if your teeth had significant gaps or crowding before braces. Since they’re permanent, you don’t have to worry about taking them in and out, but they can make flossing a bit trickier.

How Long Should You Wear Your Retainer?

This is a question almost everyone asks. The short answer? A long time. Orthodontists generally recommend wearing retainers 24/7 for the first 3-6 months after braces are removed. After that, you might switch to wearing them only at night. But don’t be surprised if your orthodontist advises lifelong retainer use, especially for nighttime wear.

Why so long? Even after the initial period, teeth can shift due to natural factors like aging and changes in bone structure. Many people who stop wearing their retainers after a few years notice their teeth gradually moving back. To keep your straight smile in check, long-term retainer use is key.

What Happens If You Don’t Wear Your Retainer?

So, what happens if you skip a few days (or weeks) without wearing your retainer? Well, it’s not good news. Without that support, your teeth can start to shift, even if it’s subtle at first. You might wake up one day and notice a gap that wasn’t there before, or that your bite feels off.

The longer you go without wearing your retainer, the more your teeth can shift, making it harder to get them back into place. In severe cases, you may need to go through orthodontic treatment again. It’s estimated that up to 25% of orthodontic patients experience significant relapse that requires retreatment. And let’s be honest, no one wants to go through braces twice.

Does a Cracked Retainer Still Work?

If your retainer has a small crack, it may still work for a short period, but it’s not recommended to continue using it long-term. A cracked retainer could lose its ability to hold your teeth in the correct position, leading to shifting. Additionally, wearing a damaged retainer can create sharp edges that might irritate your gums or mouth. It’s a good idea to contact your orthodontist as soon as possible to get a replacement retainer before any significant relapse occurs.

How to Clean a Retainer That Has Plaque

best ways to properly clean your retainer

If your retainer has built-up plaque, it’s important to clean it thoroughly to prevent bacteria and bad odours. Here’s how you can clean it effectively:

Soak in a Retainer Cleaner: Use a retainer or denture cleaning solution, which is designed to break down plaque and keep your retainer fresh. Soak it in the solution for 15-20 minutes.

Use a Soft Toothbrush: After soaking, gently scrub the retainer with a soft-bristled toothbrush (without toothpaste, as it can be too abrasive) to remove any remaining debris.

White Vinegar and Water: For a natural cleaning solution, mix equal parts white vinegar and water. Soak the retainer in this solution for 15-20 minutes, then scrub it gently with a toothbrush.

Baking Soda Paste: You can also make a paste using a small amount of baking soda and water. Apply it to the retainer, scrub it gently, then rinse it thoroughly.

Remember to clean your retainer daily to prevent plaque buildup from recurring.

What If My Teeth Relapse?

If your teeth relapse, meaning they shift back towards their original positions after orthodontic treatment, you may notice that your smile isn’t as straight as it once was. It can be frustrating after all the time and effort you’ve spent with braces, but it’s not uncommon. There are several ways to address dental relapse, and the treatment you need will depend on the severity of the shifting.

Here are some common solutions for addressing dental relapse:

Start Wearing Your Retainer Again

If you still have your retainer and it fits, start wearing it immediately. It may be uncomfortable at first, but wearing it more often can help your teeth move back into place. If it no longer fits or causes pain, contact your orthodontist for guidance.

Get a New Retainer

If your teeth have shifted only slightly, a new retainer might be enough to reverse the relapse. Your orthodontist will take new moulds and provide you with a custom retainer that can gently guide your teeth back into position over time.

Consider Retreatment

In more severe cases of relapse, you may need a second round of orthodontic treatment. This doesn’t necessarily mean going through full braces again. Clear aligners, such as Invisalign, are a popular option for mild to moderate relapse. They can discreetly correct the shifting over a period of months.

Permanent Retainers

For patients who are prone to relapse or have had significant orthodontic correction, a permanent (or fixed) retainer may be a good option. These are thin wires bonded to the back of the teeth to prevent them from shifting. They provide continuous support without the need for removal.
