Hello and welcome,
Thanks for writing to us.
may have extracted your permanent premolar teeth to get spacing for orthodontic movement of teeth through orthodontic appliances.
If you are not willing for orthodontic treatment,you could have informed your dentist prior to getting the teeth extracted.
At this state,its better to get orthodontic appliances inserted.
Since your teeth are malaligned,and the only way to correct them is through braces application,please go for it.
It won't be painful and once the treatment has completed,your smile line as well as confidence level will enhance it.
Hope this helps.
I wish you good health.
