Hello,

I am trying to get some advice about my 4yr old daughter's top front
tooth.  We have just noticed it is looking a bit gray, and from behind
there is clearly a dark centre to it.  So, I gather that most likely
the nerve has died.  She complained of pain a couple days ago, but
doesn't seem to bother her now, and there's currently no swelling or
redness.

I called one dentist and made an appointment in two days.  He said
that if it is a dead nerve, he'll extract the tooth, because as the
nerve breaks-down, there is a chance those decomposition byproducts
can damage the new tooth that will come down.

I called another dentist for a second opinion on the matter, and he
didn't seem worried about that idea, and just said that barring any
infection, he'd just leave the tooth in and let the new one push it
out one day.

Who do you agree with - extract the tooth, or OK to leave it in?

Thanks very much !
Charlie
