An abandoned baby's rare dental quirk may be the key to finding her parents.
Named Chloe by her rescuers, the tiny girl is just two weeks old, and already she has her first tooth.
Chloe was found in a plastic bag outside a Texas apartment building by a woman out walking her dog last week.
"More than likely her mother didn't have any type of prenatal care," Estella Olguin, spokeswoman for Texas Child Protective Services, told ABC's Good Morning America.
Weighing just four pounds (1.81 kg), doctors say she was premature.
Police told ABC News that the baby's tooth may be helpful in locating her parents.
Found in one in 2000 babies, so-called natal teeth can be associated with hereditary conditions.
To further aid the investigation, Texas police worked with a sketch artist to render images of what her parents may look like.
Chloe's abandonment on the street caused public dismay in Texas, where laws have been enacted to allow parents to anonymously surrender children at police stations and hospitals.If the parents are unable to care for Chloe, authorities told ABC they have many offers from families hoping to welcome her as an adoptive or foster child.
