Hai! A few of us in my mum group actually pakai braces masa pregnant, and honestly most cakap ok lang, just make sure your dentist knows you're pregnant so dia tahu which treatments to avoid, especially the X-rays and heavy procedures. Tapi sebab hormone changes boleh cause swollen gums and more plaque buildup during pregnancy, just extra careful dengan oral hygiene je, and maybe inform your orthodontist so they adjust the tightening schedule if needed. Tengok dengan your dentist first to make sure everything is safe, especially since it's pregnancy-related and really individual je.
