Uprighting your upper 2nd premolars can be achieved with Invisalign or fixed (traditional) braces. If your tooth is very short on the palatal (side facing inward), then it may be more efficient to upright the tooth using fixed braces since the Invisalign aligner will have a smaller surface area to grip on to with a short tooth.
Anterior crossbites (that occur in the front teeth) can be solved with Invisalign or fixed braces. The bigger question is the reason for the crossbite being present in the first place. I have covered this here.
If there is severe crowding or if you need to camouflage an underlying skeletal proportion issue, extractions should also be considered. Which teeth need to be removed should be carefully assessed based on your current facial profile and the health of your teeth.
Sometimes non-extraction (and non-surgical) cases may be more difficult and unpredictable to solve especially in the 2 instances I have mentioned above.
Your dentist or orthodontist can better advise you on your treatment options after a thorough evaluation, so that you can achieve your goals.
