That's really common in toy breeds. Two of my girls are spayed and I had the deciduous teeth removed at the same time. Even if you aren't going to have her spayed, you should have them removed at some point. She'll have bigger dental problems to deal with on down the line if you don't. I haven't noticed a lot of pain afterward in my dogs or any others, just judging by the fact that they still eat normally and like to chew on things. As long as he can just pull them and not cut them out (like if a person has an impacted wisdom tooth), she'll probably be acting the next day like nothing even happened. They usually come out easily and the only reason they put them under anesthesia is to keep the dog still. Dogs aren't very receptive to people messing around in their mouth
