Why an aligner may not fit
Aligners can stop fitting if teeth are not tracking as planned, the tray is damaged, attachments are missing, wear time has been inconsistent, or the wrong aligner in the sequence is being used.
What to check first
Check the aligner number, look for cracks or distortion, compare the fit on each tooth, and avoid skipping ahead unless your clinician has told you to.
When to ask for a review
If the aligner will not seat, repeatedly lifts away, causes unusual pain, or no longer fits after a break in wear, ask for clinical advice before continuing.
