    Natal and neonatal teeth are an anomaly that involves teeth erupting in a newborn infant's mouth earlier than usual. The incidence ranges from 1:2,000 to 1:3,500 births. Natal teeth are more frequent, approximately three times more common than neonatal teeth. Some authors reported a higher prevalence in females than males.

    en.wikipedia.org/wiki/Neonatal_teeth

    The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the highest prevalence is found in the only study that relies on personal examination of patients. [3] Natal teeth, and neonatal teeth, can be the baby's normal deciduous teeth, sprouting prematurely. [4]

  4. Hypodontia - Wikipedia

    en.wikipedia.org/wiki/Hypodontia

    A delay in tooth development may also serve as an indication, whereby the absence of an adult successor slows down the normal resorption of the roots of the baby teeth, which is the progressive loss of parts of the tooth. Misplaced (ectopic) positioning of the adult teeth may be discovered upon examination or a radiograph.

  5. Ectodermal dysplasia - Wikipedia

    en.wikipedia.org/wiki/Ectodermal_dysplasia

    The genetic cause of ED lies in mutations, or changes, in certain genes that play an essential role in forming ectodermal structures. These genes are part of signalling pathways—most notably, the EDA/NF-kappaB pathway—which guide the development of hair, skin, nails, teeth, and glands during embryonic growth.

    en.wikipedia.org/wiki/Dentinogenesis_imperfecta

    The main distinguishing feature is "shell teeth", a term used to describe the unique appearance of the baby (primary) teeth; the primary teeth have multiple pulp exposures and radiographically appear hollow as the dentine layer is thin (dentine hypotrophy) and the pulp chamber is very large.

  8. Tooth eruption - Wikipedia

    en.wikipedia.org/wiki/Tooth_eruption

    Although tooth eruption occurs at different times for different people, a general eruption timeline exists. The tooth buds of baby teeth start to develop around 6 weeks of pregnancy. Adult teeth buds start forming around 4 months of pregnancy. The entire tooth will start to form from the crown down to the root. [8]

  9. Early childhood caries - Wikipedia

    en.wikipedia.org/wiki/Early_childhood_caries

    Prevention of early childhood caries begins before the baby is born; women are advised to maintain a well-balanced diet of high nutritional value during pregnancy. [9] This is important since teeth start developing before birth if the diet is not sufficient, a condition called developmental dental defect may occur including enamel hypoplasia. [12]
