If you’ve just switched to a new aligner and it doesn’t seem to sit flush on your teeth, don’t panic. This is actually a fairly common experience with Invisalign. Aligners are designed to gradually move your teeth into new positions, which means the trays may feel a little tight at first. However, if the aligner doesn’t seat properly after a couple of days, it may need some attention.
Fit issues can happen for several reasons: maybe you skipped wearing your previous trays as consistently as recommended, or your teeth are simply moving a little slower than expected. In rare cases, the aligner itself might not have been manufactured quite right.
