Gap or Space between Upper and Lower Teeth, after Invisalign Treatment. (photo)

Question

My invisalign treatment on fixing my overbite has been going on well and almost done. I'm now on 36/38. I'm quite happy with the new alignment of my teeth. However, there has been a large horizontal space between my upper and lower inner teeth. This is unacceptable especially when I remove my tray and while eating. In fact, I can't use my inner teeth to chew at all. I'm afraid that there will be no improvement on this at my final tray. I wonder how other Invisalign cases resolve this gap issue?

Tobey, hello. On occasion space between upper and lower back teeth during Invisalign treatment can occur. Do not worry. It can be closed. Usually it takes several week to naturally settle. In case if it does not, space can be closed using elastics within a very short time. Usually 2-6 weeks.
Good luck.

A slight opening in the back (less than 1mm) will settle over time once you are in retention phase and are wearing retainers during night time only. If the gap is significantly larger, then some active settling of the bite can be achieved with up and down elastic wear for 2-4wks prior to finishing the treatment. Cheers!
