Help! My Invisalign Aligner Doesn’t Fit – What Should I Do?

Starting a new set of Invisalign aligners can sometimes feel tight, but your trays should still fit securely over your teeth. If an aligner feels unusually loose, won’t fully seat, or seems impossible to put on, it may be a sign that something is wrong. Fortunately, many fit issues can be corrected quickly with the help of your dentist or orthodontist.

Understanding why an aligner may not fit can help you avoid treatment delays and keep your smile on track.
