I've noticed a black spot around his molar teeth in between the gum. I am absolutely gutted :-( I am sure it is one of the molars that are next in live to fall out if they follow the normal pattern. He uses a electric tooth brush and mouthwash. I could cry. He isn't in any pain even when I touch it. I was hoping it was some food stuck inbetween. I've been researching and apparently pre babies have weak enamel. He was an early baby and I had pre eclampsia and was on tons of mess. I was hoping breast feeding would have strengthened them :-(((( . How was this effect his adult teeth??? Is there anything they can do to strengthen them his bottom adult teeth look yellow and not very dense and I brush them thoroughly :-(((
