i had bad dental problems with scott and it was all because the cheeky wee bugger was stealing my calcium lol.
make another appointment at the docs. your right it is an infection. and you will need to keep doing the salt water and mouth wash stuff just to keep it clean so it doesnt spread.
it wont harm your baby but you will need to get it checked out. find a dentist you like and make sure they know your preg. and it wont scare you so much to get it checked out. thats what there there for.
but in other words yer lill ones fine
