My daughter will be 10 in October. She still had a milk tooth, bottom incisor, which showed no sighns of coming out. Our denstist said that it was best to remove it to encourage the adult tooth to come through (he x-rayed to make sure it was there) as he said the milk tooth would possibly stay until she was in her late teens before falling out. He plans to keep an eye on it and if there is no movement in the next year or so, refer her to an orthodontist to have the bottom teeth braced and pushed together so there will be no gap when she is older.
Does anyone else have any experience of this? TIA
