It can. But honestly in my experience it takes quite some time. Most of the patients I've treated to the point of reconciling their curvature were here for other long-term conditions such as cancer or autoimmune. So as a byproduct of all the treatment that is often required to treat these types of conditions they end up with a straight spine (part of that is our system which heavily uses huatuo points - those near the vertebral segments).
If you have limited pain and no trouble, it probably wouldn't be worth the effort. If you were to try, however, you would probably have appointments weekly for 3 months and then perhaps every other week for an additional 6-12 months would be my guess.
Sometimes it will go much faster, but I don't want to raise any expectations about the process. There is a lot more to the treatment than this, but at the end of it you are moving each vertebral segment a millimeter at a time and then moving all those below it and then back up and do it again and then again all below, etc. until you get it straightened out.
