difficulty to fully remove attachements

[Marika]

hi invisalign community!

hopefully a kind specialist of invisalign can help me... i have a concern with the incomplete removal of my attachements...

My front teeth have a natural double curve on them "~", its "signature relief"... So when the dentist removed the attachement that was on 1 of them, he polished it flate without its natural relief. So my tooth is slightly different shape(finish) from my other front tooth. In other words, although my tooth is evened out, it is like I'm having a little lake filled with the left overs of the attachements... (what ads to the problem, though not related to my current question, is that the attachement was much more yellow then my emanel !!! so although my tooth is evened out, that little lake is like a yellow stain).

i have 2 questions:

1. is there any polisher-machine enough precise to actually follow the natural movement-curve of my tooth,
without damaging my emanel?

2. is it possible to chimically liquify the remaining of the attachement instead of using the polisher-machine?

thanks so much in advance !
