Body modification in Mindanao

I found the photo above while searching for something totally unrelated.  Unfortunately the accompanying text at the link is in ?Romanian.   All I can discern is the place names of Mindanao and the Philippines, and some words that look like "modify" and "rudimentary instruments."  A TinEye reverse-image-search doesn't help, and Babelfish doesn't offer a Romanian-to-English option.  And I can't find anything relevant with the googling.

The lady's lower teeth look to be intact, and black probably from betel juice.  But the upper ones are incredibly carved.  I've seen photos of modern dental modification in which the teeth are abraded into saw-like points, but this lady's dental work is the most elaborate I've ever seen.

TYWKIWDBI gets a couple thousand visitors a year from the Philippines, a couple hundred of whom log on from Mindanao, so perhaps some reader will recognize this process.  Or perhaps there's an academic dentist out there.  If anyone has information (or a link?) that would help explain this photo, please leave a comment.

p.s. - somewhat related is the Mesoamerican "King of Dental Bling."

Addendum:  It never takes long on this blog for someone to come up with answers to the most arcane questions.  Conor found a Google translation of the page in question, and Mlle Titam found this explanatory video:
