In this brief segment, Dr. Katie To cautions patients that removing mercury‑based dental amalgam and replacing it with BPA‑containing plastic materials may simply exchange one toxic exposure for another. She emphasizes that any restorative material placed in the mouth remains there continuously, so patients should undergo compatibility testing to ensure they are not adversely reacting to the new material before it becomes a permanent fixture.

Because the last thing you want is taking out mercury and put in BPA, toxic forever chemical plastic. That's not what you want. You have to make sure that you test to see which one you're compatible with. Because once the dentist put in the material, you go home with it and it's in your mouth 24/7. You want to make sure that you are compatible with the material, with anything they put in your mouth that you go home with, that you're not taking out.
