Can pregnant women have their teeth filled?

Pregnant women can not fill teeth. This is due to the need for local injection of anesthetic drugs when filling teeth, drug ingredients are easy to be delivered to the fetus through milk, easy to induce premature birth, threatened abortion, etc.; filling teeth are mostly composed of chemical components, which are easy to cause fetal abnormalities, chromosome abnormalities, etc. If you need to fill teeth, you can seek medical treatment after the end of lactation.
