OMG!! ARRGGH! None of those options sound nice! I so did not want to hear this! I am about to take my toddler (18 months) to the dentist for exactly the same problem. I noticed yesterday that one of his top front teeth has nearly disappeared/been pushed back up into his gum. He looks really weird! I have no idea how he did it - the only thing I can think of is maybe he banged it on the supermarket trolley - as he started crying alot when we were shopping but, I just thought he was tired and fed up as it was the end of the day. There is no blood or anything but, he did complain a little when eating dinner last night.
When I called the dentist to ask they didn't act like it was an emergency or anything and the lady on the phone even patronised me a bit by saying "you do realise that when they are teething their teeth can disappear/reappear" - to which of course I replied (polietly) that he is 18mo and got his front teeth over a year ago!
Anyway I will let you know how I go. I really hope it can re-emerge and that he hasn't done any serious damage. A fake tooth sounds so bizarre for such a young child and anesthesia is something you never want! but, on the other hand, on my little boy it looks really yuk pushed up the way it is!
Okay so I just got back from the dentist. He said that there is not much that he can do - it has definately been pushed up due to some trauma. He said that he is hesitant to take xrays on someone so young, even though they only have low emissions he still doesn't like too. He said it may have bumped the permanant tooth but, that there is no way to tell until it comes through and that if there are any marks on the permanant tooth then they can be fixed later. He told me to keep an eye on the tooth for any change in colour and particulaly blackening, or blistering/pimple like appearance on the gum which may indicate nerve damage; in which case it will probably have to be removed. He said it may re-emerge a little but, probably not back down to the same length as the other one. *sigh*/*fingers crossed* He took note of where it is in relation to the other front tooth (about 1/3 of the length) and told me to come back in two months and he will check it again. I asked him if he would do an xray in two months and he said maybe, probably not?!
I asked him about it affecting speech and he said that as long as there is a little bit of tooth there then it shouldn't affect speech. Hmm. I am a bit concerned about this as I am a teacher and I have seen first hand the ways impared speech can affect the literacy of children.
