I have previously had braces and then lost the retainer of course. I decided to try 6 month smile and it was a neat experience. As you can see the braces are clear and in actuality you only have to wear them maximum 6 months versus traditional braces. I only needed by lower teeth straightened and decided this would be the product for me. I went to my dentist and he took before and after photos of my smile. What a difference and if I had to do it again I probably would choose this. I just had to adjust to eating mashed food and no bagels or potato chips. My visits were weekly, to two weeks to monthly. So make sure you adjust your schedule. The price was around $2000.
