Natal teeth are teeth that are already present at the time of birth.Natal teeth usually occur in pairs and generally develop on the lower gum, where the central incisor teeth will appear.
The exact etiology is not known. Infection,febrile states, trauma, malnutrition, superficial position of the tooth germ, hormonal stimulation and maternal exposure to environmental toxins have been implicated as causative factors.
Natal teeth are usually not well formed, but they are firm enough that, because of their placement, they may cause irritation and injury to the infant's tongue when nursing. Natal teeth may also be uncomfortable for a nursing mother.
Frequently, natal teeth are removed shortly after birth while the newborn is still in the hospital, especially if the tooth is loose and the child runs a risk of aspiration, or "breathing in" the tooth.
