Tooth movement is incredibly common, and not just among people who've had orthodontic treatment. After braces or aligners, even patients who followed all the aftercare advice can experience something called "orthodontic relapse" - their teeth starting to move again.
We get this question a lot at our practice in Sandbach, so we've pulled together this article on why it happens and what to do about it.
Is It Possible for Teeth to Shift After Invisalign?
Invisalign® is very efficient at moving teeth into the desired positions, but it can't change the ligaments that connect teeth to your jawbone. Those ligaments are elastic and easily guided during treatment, but once treatment ends they tend to pull teeth back towards where they started. People with more complex cases tend to experience more relapse, but everyone is affected by this on some scale.
What Affects Tooth Movement After Invisalign?
The single biggest factor is not wearing a retainer. Retainers are custom-made devices that maintain the new position of your teeth, and whether they're removable or fixed, they're essential to stopping relapse. Other factors include:
- **Ageing and natural changes** - teeth shift naturally over time, particularly in the lower arch. Changes in gum and bone health can contribute.
- **Oral habits** - grinding (bruxism) puts pressure on teeth and can shift them. A nightguard helps.
- **Gum disease** - weakens the support around teeth and makes shifting more likely.
- **Tooth extraction or missing teeth** - gaps left untreated allow neighbouring teeth to drift in.
- **Trauma or accidents** - any knock to the teeth or jaw can disrupt alignment.
Can Orthodontic Relapse Be Prevented?
Yes - consistent retainer wear is the single most effective preventative. If you've worn aligners, you're already used to a remove-and-replace routine, so a retainer should feel familiar. Your orthodontist may recommend a fixed retainer (a thin metal wire bonded behind the front teeth), but these only hold the front 4 to 6 teeth, so a removable retainer on top is often needed too.
If you do notice your teeth shifting, speak to your orthodontist. For minor shifts, regular retainer wear may be enough. If movement is more significant, your orthodontist may suggest a short refinement with Invisalign® or fixed braces.
Can My Retainer Fix the Issue?
Retainers are designed to hold teeth in place, not to move them back. If teeth have shifted, forcing the old retainer back in can loosen and ruin it. Speak to your orthodontist first.
How a Specialist Orthodontist in Sandbach Can Help with Relapse
If your tooth movement is minor, your last Invisalign® aligner may be enough to nudge things back - but only under your orthodontist's guidance. Trying to do it yourself risks pain and unwanted movement.
If the relapse is more significant, a short top-up course of Invisalign® may be the right route. We're specialists in Invisalign® here at Cheshire Orthodontics and can guide you through it.
