The first baby teeth to fall out are typically the two bottom front teeth (lower central incisors) and the two top front teeth (upper central incisors), followed by the lateral incisors, molars and canines. Molars typically fall out between ages 9 and 12 and are replaced by permanent teeth by about age 13.
While most infants get their first teeth months after birth, some babies are born with one or more teeth. These are called natal teeth. Natal teeth are relatively rare, occurring in about 1 out of every 2,000 births. It can be a shock if your baby is born with teeth. But you donât need to worry or take action unless the teeth interfere with feeding, or are a choking hazard.
