Crowding of teeth. Consuming treatment?

I have consulted many doctors but every doc has a different opinion so I'm quite confused.My main problem is with the upper jaw.The two front teeth are a bit protruding and overlapping other teeth. Even if my mouth is shut,these two teeth are visible slightly. I thought of going for braces but I'm concerned because my nose is sharp, and I don't like the flat mouth which results due to the braces. I was suggested to extract 4 wisdom teeth but I'm a bit reluctant as I don't want my jaw to lose the slight outward edge and become completely flat inwards. I have my x rays and would love to know the solution to my problem.Also,my main concern is front two teeth of upper jaw and if that problem is sorted,i can let the other teeth to be a bit crooked.What would be the best and less time consuming treatment??
