Should I be concerned about an underlying genetic abnormality?

My kid was born with a natal tooth- a lower incisor that had no root system. It fell out when she was 4 days old. She is 16 months now, and just erupted a tooth in the same spot. That tooth appears to be two teeth fused together at the bottom- it looks "split" and has a "v" shape in ther middle of it. She has about 7 other teeth that all appear normal. Should I be concerned about underlying dental conditions, genetic abnormality, etc?

Answer: Underlying Genetic Abnormality

By Sarah h

More than likely her permanent teeth will not have the same genetic abnormality as her primary teeth. A "split" tooth or two teeth appearing to be fused together is called gemination. When the teeth were developing, they fused together to form one tooth. This is similar to having two twins that are fused together permanently. This is more common on the maxillary (upper) teeth and occurs in about 0.5 to 2.5% of primary teeth in Caucasian children. It is less common is permanent teeth only occurring about 1 in 250 people. Once radiographs are taken, your dentist will be able to determine if your daughter is congenitally missing any permanent teeth or if there are dental abnormalities present.
