But I think it actually does. School districts do have to maintain some level of student health, hygiene and sanitation.
I can tell you the oral hygiene of these kinds of items is butt nasty.
And yeah, right, like these kids really have an ultra-sonicator bath with dental cleaning solutions for properly sanitation...
What happens when these items tarnish? Do they really have the "prophy angle" (that "suction cup" thingy that goes around in circles when the dentist cleans your teeth) to buff up the metal? Or do they use metal cleaner with a rag for their grillz?
I personally have seen gold-alloy based inlays. They were on molars of a patient my father was treating and built like a "Maryland bridge" format for the teeth. The item had to be cemented and adjusted to the mandibular-maxifacial biteline.
Moreover, dentists use to make their alloys with gold. The gold as a metal has lead in it and is expensive. Also, gold is a soft metal that does not hold its shape, even in alloy based amalgams (fillings).
Now, most amalgams are done with either an alloy, which contains some silver or plastic composites, which actually last longer, hold their shapes, more durable, has a healthier safety record and efficacy.
No board certified dentist would waste his or her time on making grillz. Besides the malpractice alone would be too cost prohibitive.
So if dentists are making grillz, they I would really check their licensing and report them. They would definitely not be a part of any legitimate dental society, like the American Dental Association or National Dental Association... And if they are, then they are lusers who cannot do legit dentristry and aren't interested in better oral health...
