All three are actually good. The key is whether your sister's teeth are buckteeth. If it is buck teeth, the overall effect is really good. I was corrected at Pok Oi Hospital in 2600. It is estimated that it should be around 4000~5000 now.
If your sister has irregular teeth, it's not easy to deal with, just for a long time.
But if I remember correctly, the stomatological hospital is really expensive, but it is estimated that the price gap will not be too big now.
The key is to try not to deform the things on the teeth when correcting, because it is still more expensive to change them.
