In some individuals, the additional teeth can erupt far from the dental arch, within the maxillary sinus. The extra teeth may also migrate to a different location after development.

According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
2009 – from the stem cells were grown full teeth in mice, and even managed to grow a tooth root, previously it was not possible, but there is a problem, it is that grown teeth were slightly less "native" teeth. [1] 2013 - Chinese scientists grow human teeth in mice using stem cells taken from human urine. [2]
