braces and adult

Are braces worth it ? 
I'm 22 and I have always felt very uncomfortable with my teeth it's a flaw I think my question is do braces really work I regret not getting them when I was younger but there expensive!!!
Now I can pay for my own dental work I really want to get braces to fix my teeth I'm tired of them being ugly 😥has anyone got them as an adult and they straight ur teeth really well ????
