Hi, everybody! I am Melanie Raposo and welcome to Mommy's Minute. When you are pregnant, your blood flow increases which can cause your gums to swell and bleed. This can lead to gingivitis. The rise in hormones makes your mouth very sensitive to bacteria, also causing gingivitis. Morning sickness is also a contributing factor. Vomit contains stomach acid, which can eat away your gums and teeth, making your mouth very sensitive. To find out how to prevent pregnancy gingivitis, visit www.ThePregnancyShow.com.
