No, but I googled on the last 5 words of the 1st of your lines I have quoted and found this, in google books (which won't allow me to quote text, so I had to use the snipping tool):

OK, so I can't upload the image without putting it on the web, so I will just reference the book:
Periodontal Diseases: New Insights for the Healthcare Professional: 2013
See chapter 6, Therapies and Treatments.
Page 60.
Suggests Hydroxyapatite would actually protect the enamel from up to 90% ascorbic acid (although I don't know how "90%" is actually defined.
So not sure it would be such a bad thing. Perhaps if done excessively it might be though, or using too strong a solution.
Haven't read all that much of it, but that chapter seems to be looking fairly favourably on ascorbic acid in the context of periodontal disease/plaque.
EDIT: OK, so I later realised that was a patent application and not a scholarly research tome. The submitter would obviously have a vested interest in saying that it's all good. Kind of interesting, nevertheless.
I found the actual patent (or a very similar one, in text form here):
http://www.google.com/patents/US20150037265I randomly found another source that claimed that a neutral sodium ascorbate solution would be better if one's main interest was in dental/periodontal hygiene. However, I'm not sure it was a particularly authoritative source, just another alternative health site, and I didn't have the patience/persistence to investigate it.
