For the last year[or so] i've had invisalign. I had 10 aligners and me and my mum were hopeful that they were going to work. After the 10 my teeth still weren't straight so more impressions were taken and after 6-odd weeks i got my 'refinements'. i had 6 of these. after the 6 refining aligners my teeth still weren't straight. so when i went back to my dentist more impressions were taken for more aligners.
i went back to my dentist today as they called me for an ASAP appointment. he told me that because i had had invisalign express [which i'd thought i must've had, but we didnt find out until today] and i could only have one set of refinement aligners.
he took more impressions today, telling me that i was going to have plates made up.
i still have a couple of teeth that are 'wonky'.
is this a way of straightening teeth?
obviously he knows what he's doing but i cant help but wonder whether this will work.

anyone have any experience with these?
help is appreciated.
