I got my braces out about 3 months ago, and my dentist told me that after some time, I can start wearing my retainer only at nights. Since I've been wearing it all the time for three months, do you think it's okay to start only wearing it overnight?
Yes but do not stop wearing them EVER
You have to consult your orthodontist. He will see how your teeth are tightening in your bone and then make a decision. Listen to what your orthodontist says. If it's best for you to wait. Wait!
