IT took an hour long and was more painful than smart-lipo. My gums were bleeding and burning. Results were not what i thought they were going to be. They told me at the end that this procecudure works better for people the smoke. blah blah blah.
any way i even tried to maintain this with the white strips and i think i worked better for a bit but after like 2 weeks you go back to normal. i really recomend the listerin whiting its easy and better and cheaper. i paid 300(1/2 with the coupon that i had and 100 for the dentist to check my teeth.)
it burn, hurt and not worth it. I learned my leason by trying it though.
