Before I got invisalign I did a two year research about braces and invisalign. It started when I got my 4 wisdom teeth removed on march 2010. Then I had one porcelain crown placed. And did whitening with zoom. Then dedicated myself 6 months to look for the best dentist to put me on invisalign. I met with 3 dentists and 8 orthodontists the good thing is that they all offered free consultation for invisalign and I bring my own X-rays and recent photos front the first ortho I saw. I just purchase them to avoid the hassle of having them taken again and again. Plus the dentist could have a full vew of my case on they first free consultation. I wanted invisalign, but wanted to hear the experts advise. Some orthos told me to use regular braces, but I realized their own teeth wash straight! And finally decide to do it with Dr. H. His office and was top technology and he is a mature man so it was experience plus technology. I paid all upfront, something I shouldn't have done since he offered easy monthly payments. First they put a machine on every single angle of my mouth. Took over 2 hrs and I got to see my teeth on a 3D image. This technology is so cool! He didn't do it. It was a technician who did this. Will write the rest soon and scan my pictures to share. Thanks... Updated 12/15/11 Here are my pictures before I started my treatment with invisalign. Also I wanted to write about the cons; I wanted to let your know that when you have the first set of invisalign you must keep it on long enough until you get used to it you might get knots!!!. I personally couldn't stop moving my tongue touching the edges of the invisalign until I cut it. But I kept it on; I kept it on and by the time I changed to the second aligner I stop moving my tongue and got used to wear it. But every new aligner really bothers on the first day. So I suggest you put it on before sleeping when you are very sleepy and take a tylenol pm or something to keep you relaxed. Is better than doing it in day time. Other thing is that if you are going to have some teeth filed in between take tylenol before! or you WILL have a head ache. Will keep you posted with some more photos in the future. BTW after looking at those pictures today I noticed BIG difference. I hope the final results reach my expectatives. I still have 9 months or more to go.
