My friend’s great-grandma, or great-aunt, I can’t remember which at the moment, told her this little story. Her son lost all four of his front baby teeth, but instead of four permanent teeth growing back, two _big_ permanent teeth grew back! Has anyone ever heard of this happening before? Is it common? I can’t for the life if me find any information on this! ---

I’ve seen it, the incisors are fused (syndontism) or are incompletely _twinned_ from one root (schizodontism). Not at all common with permanent teeth. It is found more with deciduous teeth. Some info can be found [here](http://www.uic.edu/classes/orla/orla312/VariationInToothMorphology.htm) and [here with pictures](http://www.dentalnews.com/insidearticl8.htm). ---

Thanks **peri**! I knew there had to be information on it somewhere, but I had no idea what the condition was called!
