Hi Daisy,
I have gingivitis problem as early as 6 weeks, and now there's another swollen gum somewhere that i need to go back to the dentist. (but i'm avoiding it and gargles with salt cure only, so far getting better)
I asked him about dental procedure last time, and he said it IS OKAY to do it, even xray and anaesthesia, though they avoid it if necessary. He said he has done numerous root canal with preggies even with his preggy wife and it is okay if it really hurts badly. Very safe.
I was scared too to have my gums cleaned few weeks back, but i rather have it treated early and not bear the pain.
If i go back again, i'll ask about extraction. He also said that most preggy women suffer tooth problem esp on the 2nd trimester.
Take care.
