This is the advice of Baystate Dental, which told WWLP.com that this kind of brace can be worn by anyone from their teens onwards.

"You will get nice straight results," he added, explaining that most treatments are finished within 12 months.
Justin Fenner, writing for the Into the Gloss section of Styleite, recently criticised model Karlie Kloss for only wearing her Invisalign braces at night while she is asleep.
"The idea behind wearing these things is to keep them in as long as possible so that the trays gradually move your teeth," he pointed out.
