Can Aligners Fix Teeth That Shifted After Braces?

It’s not uncommon: after years of wearing braces, your teeth slowly begin to move out of alignment again. Whether due to forgetting your retainer, jaw growth, or natural shifting over time, this situation is called orthodontic relapse—and it happens to more people than you might think. Yes, aligners are an excellent solution for teeth that have shifted after braces. With a custom-designed series of trays, aligners gently guide your teeth back into their ideal position—without metal wires or brackets.

What Is Orthodontic Relapse?

Orthodontic relapse occurs when teeth start drifting from their aligned positions after previous orthodontic treatment. This is especially common when:

  • Retainers weren’t worn consistently after braces

  • Teeth and jaw continue to shift with age

  • There’s crowding or spacing that was never fully resolved

  • Natural tooth movement occurs due to biting, grinding, or missing teeth

Relapse can affect both cosmetic appearance and functional bite alignment. In some cases, even small shifts can lead to issues with chewing, speech, or oral hygiene.

How Aligners Correct Relapse

Clear aligners like Invisalign work by applying targeted pressure to gradually move teeth back into their original, corrected position. The process includes:

  1. A 3D digital scan to assess your current alignment

  2. A personalized treatment plan using past orthodontic records (if available)

  3. A series of custom-made aligners worn in sequence

  4. Optional attachments or minor procedures to optimize movement

  5. A final retainer plan to lock in the results

Aligners are especially effective for mild to moderate relapse cases, such as:

  • Minor crowding or overlapping of the front teeth

  • Small gaps or midline shifts

  • Slight bite issues re-emerging after treatment

What to Expect from Retreatment

  • Treatment time: Often shorter—3 to 9 months, depending on the extent of shifting

  • Wear schedule: 20–22 hours per day

  • Comfort: Smooth plastic aligners are discreet and easy to wear

  • Monitoring: Regular check-ins (in person or virtual) to track progress

  • Aftercare: Nighttime retainers to maintain results for life

If your case is more complex (involving skeletal relapse or major bite changes), your provider may recommend braces, elastics, or a combination plan.

Why Act Early?

The longer you wait to address shifting, the more likely your teeth are to continue moving—making treatment more complex and longer. Early intervention with aligners can:

  • Prevent further misalignment

  • Save time and cost

  • Restore your original results without starting over from scratch

  • Avoid future discomfort or functional issues
