It is not too late toclose your open bite due to thumb sucking Habit. I would find an orthodontist who uses the Damon System in your area. Damon system because of if its low friction can easily correct youropen bite. You may need need some sort of tongue training because open bite can lead to tonque thrusting habit which can undo the correctionHope this helps
So you have a gap between 2 front teeth know as a diastema and missed shaped next teeth know as peg laterals. If rest of your bite is pretty good then you could get limited ortho treatment to close the space between your front teeth then have the miss shaped teeth restored by a cosmetic dentist to its normal shape.

It looks like you may have lost a baby tooth prematurely and your adult teeth on either side of the lost baby moved into its place and caused the "extra tooth". This not an extra tooth it just needs space. It is possible to move tooth in place if an orthodontist has proper tools like TADS and DAMON SYSTEM to create space for the "extra tooth". invisalign treatment is not a good tool to do this type of treatment. I would consult an experienced orthodontistbefore excepting this treatment plan.
