The consequences of gingivitis are not just limited to your oral cavity women who have gingivitis are more likely to go into labor prematurely, and have low birth weight babies. The good news is that gingivitis can often be prevented and almost always be cured. You don't always need to see a dentist to make it happen either. There is a good range of oral gels and mouth wash products that can prevent and cure this nasty condition. If you talk to any dentist, they will tell you that excellent oral hygiene goes a long way in preventing gingivitis, and that the same goes for curing the condition once you have already developed it.
While it is indeed true that the hormones that are dominant during pregnancy, most notably progesterone, can make gingivitis worse and make it easier for the condition to develop, it is still bacteria that are responsible for causing gum problems. Now, those bacteria can only get a grip if you don't care for your teeth as well as you could. Brushing your teeth three times a day, and rinsing with a non-alcoholic mouth wash really does work magic in that respect. Gels that calm down inflamed gums also work very well. If you do notice signs of gingivitis, don't worry. Step up your dental hygiene routine, and you will most likely send the bacteria packing. Good luck!
