Didi-

In reality, the position of the teeth before you put the unit can be defined as natural, but not normal!

When I say normal, I mean average.

However, having braces put pressure on the tooth and periodontal ligament mainly and other structures.

After removing braces, there is a natural tendency for teeth to bounce (well not quite - as flowing back can take months or years).
Therefore, it is absolutely essential to have your retainers as instructed by your orthodontist.

they move your teeth into what could be a normal position thats why it hurts like hell when they tighten.

The metal and the arc to put pressure on the teeth to move in a certain posotion.
