Q: I’ve heard teeth can shift during pregnancy. Is this true?
A: During pregnancy, lots of changes occur. Not only does your body gain weight and move organs around to make room for the growing fetus, but you also produce a hormone called relaxin. Relaxin does several things, including relaxing your pelvic muscles, making your feet grow and even affecting tooth movement by impacting the periodontal ligament (PDL). This shifting can be prevented by being custom-fitted at your dentist’s office for a retainer to wear while you sleep, during your pregnancy and through nursing.
