Does taking tetracycline during pregnancy affect development of tooth growth?

Yes, taking tetracycline during pregnancy can affect tooth development in the fetus. Tetracycline can bind to calcium in developing teeth and bones, potentially leading to discoloration and enamel hypoplasia in the child's teeth. This risk is particularly significant during the second and third trimesters when fetal teeth are forming. As a result, tetracycline is generally contraindicated during pregnancy.
