i know there are people who have them older than me, but im not going to have them. ive had them before, and besides the dorky look they give on anyone older than 14, they make it harder to floss, left spots on 2 of my teeth from the first set, and are not comfortable by any means.
ive looked into the price, so im ready for that aspect
and i also had retainers...my top one was actually all behind my teeth and the roof of my mouth, and no wire, so no one knew it was there, and the bottom was clear w/ wires...after breaking like 7-8 of them and worn it for 3 of the 5 years they told me to, i quit going back and making my parents spend more $ on new ones
i guess it didnt help that my wisdom teeth didnt come in until after all that and didnt get pulled until i was 18 (iirc)
