I used to have braces as a child. now im 27 and i feel as if my teeth are protuding again.. what should i do?

See an Othodontist: Sometimes teeth can move later in life. There are many possible reasons for this. Any orthodontist should be able to figure it out quickly.

See dentist/ortho: I would first go to your general dentist for an exam to see if your teeth are indeed protruding. If you are not happy with the appearance of your teeth, there are several treatment options the dentist can discuss with you. He may refer you to an orthodontist for retreatment.

Adult orthodontics: Teeth are not like fence posts that are set in concrete and harden in place...They always have the ability to move if you don't wear retainers . Some problems are more stable than others but even unstable problems can be corrected in adults as long as they understand they will need to wear nightime retainers forever. Invisalign is often a great way to correct adult problems.

Reevaluate: Once teeth have been moved it's not like putting a steel post into concrete. As an adult all the bones in your body change over every 7 years. See 1. Your dentist to make sure you don't have a gum/bone problem. 2. Your original should be consulted if possible. If not, ask your dentist to refer you to an orthodontic specialist for an evaluation.

Talk to orthodontist: It is possible you did not wear your retainer (sounds that way) and your teeth have indeed shifted. Discuss getting treatment again with an orthodontist. Maybe invisalign? Something to consider at your age.

Relapse is common: Relapse of orthodontics is often the result of changing the original shape of the dental arch, expanding the distance between the lower canine teeth (3rd from the middle), and flaring the lower incisors to elimnate crowding. This saw 1st shown by dr. Hayes nance in 1947. Many further studies confirm. However, non-extraction treatment sells and looks good until retainers are discontinued later.
