...do they grow up into a "full" tooth iyswim?
Had a horrible night Sunday night with DD, 7 months, much thrashing around and crying (her and me, in the end), and today I can feel the tooth just through the gum, maybe a millimetre or so, a sharp line, front bottom left. She still has a stream of drool and is chewing her fist as per usual (but has been doing this since 3 months), but I am sure the tooth has popped through, rather than still being below the gum (I could feel it then too, but it felt different, fleshy and not sharp).
And - more importantly - once it has broken through the gum, does it still cause pain as it grows up properly to full tooth height?
