Some Outsourced Dental Implants Test Positive For Lead
If you're getting dental implant work done, you may want to ask if they outsource to other countries. A KPHO investigation bought 13 crowns from labs in China, Thailand and the US. Ten of them came back positive for lead, with levels from 110 parts per million to 240 parts per million. The problem may be from the surface stain used to whiten and brighten the teeth. Throughout history, lead has been used in paints because it's bright, cheap, and highly durable.

@MercuryPDX: Mercury, we've never met, but I've come to the decision that you are what makes Portland so awesome to visit (well, you and Voodoo Doughnuts)
OK, people, those are not supposed to be the teeth. The "lead pipes" are what are called impression copings, that are screwed onto the implants for a few minutes while the impression is taken to send to the lab. Then those are removed and the healing caps, which look a little like watch batteries, are screwed back into place until the crowns, which look like normal teeth, come back from the lab.
But this is not the actual issue. The actual issue is the lead in the outsourced crowns, which are independent from the implants. You don't need an implant in order to potentially get a lead-contaminated restoration if your dentist is using an overseas lab. This is why I use a lab down the street from my office. I can visit it, I know everyone who works there, and I know they are following acceptable standards for fabricating restorations. Yes, they charge more than an overseas lab, which means I don't make as much profit, but I'd much rather be able to sleep at night.
hmmm ... anyone know what the lead content limit is? 240 ppm does seem a little high, but I also don't think it'll hurt you. like at all ... of course if you often take in lead or other heavy metals ... the implants could tip your scale to the poisoned end, but I think you were headed that way anyway.
@Ichiro Death Glare: I've got an odontoblastoma patient who looks a lot like that. Managed to live into her late seventies with a complete set of her natural teeth, then a benign tumor knocks out 21-28. She's doing a partial rather than implants, though.
The one I love is the (apparent) angulation on #8. I realize they're probably using an angled abutment, but still... "comin' atcha!"
@Marshfield: The OP says it was the crowns, not the implants, that contained the lead. The implant is titanium, and unless you're shipping your jaw overseas, that can't be outsourced. However, any crown, whether it's on an implant or on a natural tooth, could potentially contain lead if an unscrupulous lab is making it.
Everybody, ASK YOUR DENTIST who will be fabricating your lab restoration. If it's a local, domestic lab, you might even be able to visit the lab and put any worries to rest.
@FangDoc: Thanks for giving us a real comment. I talked to a Korean friend who is oral surgeon about implants once and I was convinced that they were a great thing (assuming you need them--but I will keep my teeth, thanks).
I cannot believe that anyone would put lead into anything that is only intended for oral use.
Do you run a bigger risk of lead by getting the surgery overseas? I remember her saying that Seoul had some of the best oral surgeons in the world and that it makes sense to travel there for such surgery. Of course, she practiced there, so I can understand her bias.
Lead? Doesn't it bother anyone that "silver" fillings are made with mercury? I'm not convinced that the mercury in standard fillings doesn't get absorbed into our bloodstream. I direct you to a BBC documentary on the subject.

Let's worry about the mercury first.
@kendallcorner: According to the article, "The FDA has not established a limit for the amount of lead in dental work."
I don't know how much lead it takes to poison someone but I'd think that for something that's in your mouth it wouldn't take as much as for something you're just touching.

@dayron422: Yes. Yes it does.
