Teeth Shifting After Braces? Here’s What’s Actually Going On

When you were done with your orthodontic treatment your teeth were perfect. You looked in the mirror and were proud of your smile. And when your orthodontist handed you a set of retainers and told you to wear them every day, you had every intention of doing so. In fact, for a while you were incredibly consistent.
Then life got busy and you missed a night. No big deal, you wore them the next night, no harm no foul. But then it was a few nights in a row. And now it’s been a few weeks or maybe even a few years.
You aren’t exactly sure when your retainer routine slipped but it did. Now you’re here and you’ve noticed signs your teeth are shifting.
Let’s start by saying you’re not alone. We’ve all had habits slip. Second, you haven’t necessarily ruined everything and you can get back on track. You just might need a little bit of help from your orthodontist.
In this article, we’ll break down what happens with your teeth after braces, what your retainers can or can’t do at this point, and what the realistic next steps are for getting your smile back to the place you want it to be.
How Do I Know If My Teeth Are Shifting?
When it comes to your teeth shifting, it doesn’t happen overnight. Rather, it’s a gradual process where your teeth slowly drift back towards their original positioning, meaning that many months could go by before you notice.
What are the most common signs your teeth are shifting?
Your retainers feel tight or don’t fit the way they used to
This is the most reliable warning sign that your teeth have shifted after braces. If your retainers used to slide right on, but now require effort, or are applying uncomfortable pressure in new places, then your teeth have shifted from when you first got your retainers.
You’ve noticed new crowding or gaps
If you’re looking in the mirror and notice that there’s some overlap between your teeth that wasn’t there before or new spaces have opened up between teeth, this is a clear sign of teeth moving after braces.
Flossing feels different
As you know, flossing is an important part of maintaining good oral hygiene, and it can also be a good indicator of teeth shifting after braces. When you floss can you feel the floss catching? Feel resistance between teeth that your floss used to glide easily between?
Your bite feels off
When your mouth is closed does it feel like your upper and lower teeth come together unevenly? When you chew, is it uncomfortable or do your jaw muscles get tired quickly? Do you feel tension in your jaw even when your mouth is at rest? These could all be signs that your bite has shifted, and it’s important to see an orthodontist to prevent the condition from worsening.
Why Are My Teeth Shifting?
So what’s the reason behind teeth shifting after braces?
A lot of people think that teeth after braces are locked into place. But this isn’t true and the reason is because of the periodontal ligament. This is a membrane that holds your teeth in place and it has an elastic memory, which means that it naturally wants to move back to its original state, bringing your teeth with it. It’s gently pulling at your teeth and applying forces that, if not counteracted, shift your teeth back to their original positionings.
This is natural, but is the reason why consistent retainer wear is so important. Retainers push back against the forces of the periodontal ligament, and keep your teeth from drifting out of their new positions.
Can a Retainer Push My Teeth Back?
If your teeth shifted, because you haven’t been wearing your retainers, you’re probably wondering do retainers push teeth back? Will a retainer straighten teeth?
The answer to these questions really depends on how long you’ve gone without wearing your retainers and how much tooth movement there’s been. While a retainer could potentially help in minor cases, it’s important to understand what retainers are actually designed for.
Unlike aligners and braces that are constructed to apply continuous and calibrated forces to a person’s teeth in a way that creates movement, retainers are built to simply
maintain the position of your teeth. So when you start wearing your retainers again after a break, they aren’t really pushing your teeth back into place, but rather allowing the surrounding tissues to stabilize.
So what are your options based on how your retainers feel?
Your retainer fits but feels snug
In this case, there’s a chance your teeth haven’t moved all that much. In this case, you should resume consistent wear right away. The slight pressure you feel should subside as your teeth settle and they should gradually return to feeling like they did when you were wearing them consistently.
Your retainer fits but feels really tight and uncomfortable
If it’s difficult to put your retainers on or they feel really tight and uncomfortable, then it’s important to not force it. Trying to put on a poorly fitting retainer can damage both your teeth and the appliance. At this point, can the retainer move teeth back? Possibly, but it’s best to schedule a visit with your orthodontist so they can evaluate how your teeth have moved and determine the best path forward. They’ll be able to make the call on whether consistent wear of your current retainers will resolve the issue or if you need new ones made.
Your retainer doesn’t fit at all
If your retainer doesn’t fit at all, does a retainer move teeth back? No. If there’s been significant tooth movement, then braces or aligners will likely be required. However, the good news is that in many cases, a short round of Invisalign can get your smile back on track. Then you’ll get a new set of retainers to protect your results moving forward.
It’s important to note that retainers aren’t designed to move teeth and the simple answer to can retainer shift teeth back is no. In very minor cases, resuming wear may allow the tissues to settle but this is different from the controlled tooth movement that braces or Invisalign deliver.
If your retainer doesn’t fit or fits improperly, you need to see an orthodontist. If you force a retainer that doesn’t fit you risk damaging your teeth or even having your teeth forced in the wrong direction.
Do You Have to Wear Retainers Forever After Braces?
A lot of people wonder: do you have to wear retainers forever?
The honest answer: yes.
And that answer is "yes" for all of the reasons we've already talked about. Because when you stop wearing your retainers your teeth will shift.
For many people, forever sounds daunting, but when you break down the timeline, and what wearing your retainers actually looks like, forever isn't as bad as it sounds.
First Phase: Full time wear (20-22 hours per day)
This period lasts anywhere from a few months to a year depending on your case, and is the most critical period for making sure you're wearing your retainer the recommended amount. The reason being that your tissues and bones are still settling in and stabilizing.
Second Phase: Night-time wear
Once you transition to nighttime-only wear, this is likely where you’ll stay indefinitely. So while the answer to the question of "do you have to wear retainers forever after braces?" is yes; it's really just while you sleep. So in essence, it’s simply a small nightly habit.
What to Do If Your Teeth Have Shifted?
Here’s the important takeaway if you notice your teeth shifting: the sooner that you get back on track, the simpler the fix. For example, minor shifting that’s caught early can often be addressed with new retainers and consistent wear. On the other hand, if the tooth movement is more significant then it may require something like a few rounds of Invisalign followed by a new set of retainers. Essentially, the longer you wait to see an orthodontist, the more likely your case will become more complicated and expensive.
