You can also ask your Dr. if he can place a couple of pressure points on your trays. There are instruments you can use to modify them. He may be able to do that without having to do more treatment. I would definitely stay with the Invisalign trays.
If the decision was based on the facts that your need was a moderate one and you were not pressured into starting treatment, the issue here is that Invisalign, unlike other Orthodontic treatments, is a series of trays fabricated by a laboratory.If you agreed to go ahead, your Orthodontist ordered your aligners and he has to pay for the fabrication of them. They are all produced at once, since is a computer generated treatment.If you cancel now, I'm afraid you are going to be out the deposit you made, since the lab fees are more than that.I will consult with your Orthodontist about the fact that you are having second thoughts.
Have you had what's called Refinement Stage. The right canine needs to move more towards the inside, that will make it stand up taller. It still looks slightly out of place. Ask your Dr. if with a refinement phase that can be corrected. That may require you to wear a few more sets of trays, which means your not finished yet. If you really want that corrected and don't mind to wear some for a little longer I would enquire about that.Good luck! Otherwise they look nice
I definitely think that your case can be treated with Invisalign. Looking at the pictures, your case does not look very complex, as long as you see someone with experience. I don't think it's a case for a beginner provider.I also don't think it will take very long. If you were my patient I will place you in the easy to moderate difficulty.Good luck.
