Is there any alternative to straitening teeth, besides braces? How much does it cost? Where do get it from?

My dentist told me about something he started carrying. I think it's called Invisiline and it's basically a clear retainer. It can straighten teeth without braces. You wear it for a few months to a year. He said around here a lot of places were selling them for $5000 but he would probably sell them for $4000 and take payments. Call your dentist's office and ask if they carry it or if they know anyone who does. I just did a search and found their website. It's www.invisalign.com.
