What would be the effect if braces were maintained for less than two month and were removed?

Braces for that short of a period of time, removed early without any retention will not be too beneficial to you.  Even if the teeth have moved in the two months you have worn them, without a retainer, they will most likely move to right back where you started.  I would suggest expressing your concerns to your orthodontist, and discuss why you want them removed early.  Good luck!

If I understand your question I think you are asking if you remove your braces after only 2 months of wear, what would happen?  In that short a time I would say that there would be very little in the way of lasting changes taking place.  Most likely if you removed the braces and did nothing else, your teeth would move back to their original starting position.I would suggest that you discuss the consequences of removing the braces with your orthodontist.
