I am on my 5th aligner and my front teeth are still crooked, one of my front teeth isn't moving forward, I noticed since my 3rd aligner the tooth in question doesn't sit right in the brace, it seems to fill with spit because there is a gap between the brace and my tooth! At the end of the wear time of each aligner I've noticed they are only loose one side but tight on the other side! My dentist has told me we will go back to aligner number 3 then on to 4 and then 5 again, is this normal?

It is normal to revert back to a previous aligner...but, this should be a rare occurance!
Invisalign not Entirely fitting over the Teeth
It is possible that at times the teeth 'fall behind' or do not move along with the Aligners.
Make sure you are wearing them according to the instructions given by your Orthodontist (or the general dentist, if that is who is doing it for you). Ideally, you should be wearing them about 21 hours/day. If it is less, one of the things we see, is that teeth start to be left behind. This should be addressed earlier rather than later, as with each subsequent aligner, the tooth tends to fall further behind.
Therefore, it is not uncommon to at times go back a few aligners to pick up the tooth that is falling behind.
Using previous trays for Invisalign
Depending on your compliance with the amount of hours that you wear each tray it is possible for some of the teeth to fall behind. Sometimes it helps to go back to the tray that fits properly and wear it consistently to get the teeth back on truck.
