Milk teeth

Milk teeth (English deciduous teeth, from Latin deciduus - “maturing, changing, mature” and are designated as dentes decidui) are replaceable (temporary) human teeth. The name of the tooth comes from the Latin word decidere (loss). Unlike permanent teeth, primary teeth are fragile bones, consisting mainly of dentin 22-25. It is due to dentin that we can see the color of the enamel. The crown of a baby tooth has a hemispherical shape. The root of the wide cone-shaped structure of the baby tooth does not allow any chewing function. Thus, milk teeth must be replaced with permanent ones no earlier than 5.5 years of a child’s life.\n\nThe change from milk teeth to permanent ones occurs in the fifth or sixth year of life, in the age range of 5–6 years. This period is associated with the final development of the roots of primary teeth (with the exception of the first two molars, which remain for life) and with increased jaw growth. In addition, the resorption of the roots of the milk units forms special niches in the alveoli for the eruption of permanent teeth. During this period, the rudiments of the third radicals appear
