Ashley,
I have not seen your teeth and a close up photo of your teeth would help a lot. Normally simply straightening teeth that are small can make you look child like.
It is usually better at your age to have bonding done. It is paramount that you have a dentist with cosmetic training do that donding if you want it to look real.
When you are a little older--21 years old or so--veneers are an incredible option.
I hope this helps
Dr. K
