Is there any evidence out there that fillings like white composite resin or bonding material is cytotoxic (harmful to cells)? Been wondering since I’ve come across a lot of people who seem to have had their cancers arise after dental work etc. In my case I had dysplasia for a while before it turned into cancer, and it was on the same side as my fillings.

Also - how many of you have had fillings after treatment with no bad effects?
