How can i get a free orthodontist consultation?

People are telling me that i if i have any questions about my teeth and ask them if i need braces that i should go for a free orthodontist consultation, but how do i get it for free? Also my parents are saying i have perfect teeth and i am afraid that if i go to the orthodontist consultation they will tell me i don't need braces. Please just tell me how i can get a free orthodontist consultation!
