Girls, hello everyone, did anyone have lead poisoning, has it affected the baby? I had an examination at the dentist's office in the women's consultation, the doctor said that I need to remove the nerve, she pulled out half of my tooth, smeared everything with lead, she said it will kill nerves, and on Friday they will remove them. She didn't even warn me that she was putting lead in. The doctor knew I was pregnant, before that she put three fillings in me. And now I came home and I'm crying... from pain and worrying about the baby. What should I do now, run to a private clinic, let them remove this lead, or is it really not dangerous??
