Sore gums

Hormonal changes can make your gums sore, swollen and bleeding. This can be prevented by brushing and flossing your teeth daily. Because peroxide can be absorbed through the mouth, its use is not considered safe for pregnant women, so salt water really is the best bet, swishing with green tea is also known to help ease the pain. Good Luck, and congrats!

In addition to those things has she tried using orajel to numb the gum? I would try that and continue to rinse with salt water.

Peroxide is not recommended because it damages healthy tissues as well as infected ones.. If she is having any other problems like canker sores, there is a rinse aid called Vince (found at most drug stores) that works wonders. If her gums are swollen and bleeding try Gly-oxide. Tastes yucky, but it oxygenates on the gums bringing healing as well. This is recommended by dentists for gingivitis. Susu

There is an oral-gel that works great it is temperary relief it called HURRICAN

Do what the dentist told her warm salt water. also ask her ob/gyn doctor for advise. do not, repeat do not use peroxide it can be poisonous and harmful to mom and baby, people used to gargle with it but I read an article lately and it said it can be harmful. if oragels instructios say its ok for pregnant woman then use that. Hope she's ok.
