My husband, who is so vain about his teeth,
had the laser whitening done before a college reunion almost 4 years ago. Occasionally he uses the trays they provided with the service at night.
My front teeth are bonded, so they are not natural tooth material, so supposedly the whitening doesn't work on my teeth, so I haven't wasted the money to try it (I need to get my bonding redone one of these days and then I guess I'll figure it out from there!)
All my kids have/had braces, and my ortho says that the invisaligns are great for keeping teeth in place and really only work well if you don't have to move them a lot. He actually uses them for retainers, although after a few years my kids have gone to regular retainers because they didn't feel like the invisaligns were holding their teeth in place as much as they should. Also, he says it's really easy to get teeth to move, the challenge is getting them to stay where you want them. You always have to wear your retainer or you're wasting your ortho dollars!
