Ask your ortho.
I had my braces taken off 6.5 years ago. I followed all the instructions my ortho gave me. After 6 months after having braces taken off he told me to wear it during the night only.
Now that its 6.5 years since I had my braces taken off I still wear it nightly. How often can I wear it now?
Ask your ortho.
I use it everynight my otho told me to wear like that.
If you can, if they are still there could you contact your ortho?
I find each Ortho recommends different. Some say all day for 6 months, then nightly, some say all day for a year and then nightly. After about a year a few nights a week.
