I wish I could tell you for sure. There is some debate about this, but it's generally believed that mercury can come through crowns and therefore chelating while they are in is discouraged.

But again, I would try to get an answer from Dr. Cutler before making a final decision.

If there is anything else we can help with, please just ask. Most mercury based health issues can be mitigated to some degree with supplementation while getting mercury removed.

For example, you may consider trying Algin.
