Have noticed over the last few days that ds has had blood behind one of his top front teeth. Don't think he has banged it. Two weeks ago he fell and his teeth knocked into his lip which made his lip bleed but surely it can't be from that long ago. He is not grizzling about it and when I touch it it doesn't seem to cause any pain. Has gone off his food recently though.
If it does not get better over the next couple of days, am not sure wheather to take to dentist or doctors.
Any ideas??
