I did my bracers at the age of 27 and wore it for 2 years. Cost me 3k plus at penang private clinic. It was well worth it.

I still wear my retainer at night before I go to sleep and take it off when I woke up. Yup u need to wear retainer for the rest of your life because your teeth will move no matter how long u have done your bracers. Don't believe? Try 1 to 2 days without wearing retainer, and then wear it back, u will notice the tightening of your retainer. This sux I know, but u just wear it when sleeping and u save your investment for the perfect straight teeth!
