[quote="Aditi"]Good lord I never even considered the thought of "refinements", I'm sour enough as it is about this whole process.

I was considering stopping halfway through but my dentist convinced me to keep on with it. Halfway through and my teeth are looking pretty good so I think when I am done I'll say "phooey" to refinements. I think I'll be happy enough. I guess. I hope. *sweat*[/quote]
Your attitude may change as you near the end of treatment. The change in my teeth has been night and day and as much as I couldn't wait for it to end, I want to make sure I see this through. We've put in a lot of effort and money into this process so a few more months should not be a big deal.
Keep this in mind - your dentist has no incentive to keep you going as he's already been paid. If you decide to come back in a year or so to get that perfect look, that's more money from him. It's one thing if he's the one trying to get you to stop. He's not - his advice benefits you 100%. Take his advice and go through at least one round of refinements. I doubt you'll regret it.
