Résumé
There were great individual differences in eruption time of the teeth. Generally speaking, the deciduous teeth begin to erupt at 6 months after birth, but some babies are born with erupted teeth, which are called natal teeth; in addition, teeth erupted within 30 days after the baby is born are called neonatal teeth. Natal teeth and neonatal teeth may cause ulceration, aspiration, and nipple pain or trauma in the mother′s breast during the time of breastfeeding. Extraction of the teeth may cause complications such as neonatal osteomyelitis. To avoid the complications caused by these diseases, and to alleviate the suffering of patients and their families, this article will introduce the clinical manifestations, etiology and related complications of natal teeth and neonatal teeth, and then give some treatment methods and nursing methods, especially to help clinical work.
