Primary tooth

Primary Tooth

A primary tooth, also known as a baby tooth, milk tooth, deciduous tooth, or temporary tooth, is one of the first set of teeth in the growth development of humans and many other mammals. They develop during the embryonic stage of development and erupt—that is, they become visible in the mouth—during infancy. They are usually lost and replaced by permanent teeth, but in the absence of permanent replacements, they can remain functional for many years.

Development

Primary teeth start to form during the embryo phase and continue to grow during infancy. They usually start to erupt in the mouth from the age of six months to one year. By the age of three, most children have a full set of 20 primary teeth including incisors, canines, and molars. The primary teeth maintain the spaces where permanent teeth will erupt and help in the development of the jaw and muscles needed for chewing.

Anatomy

The anatomy of primary teeth differs slightly from that of permanent teeth. They are smaller in size, have a lighter color, and have thinner layers of enamel and dentin. The pulp chamber is larger relative to the rest of the tooth, and the roots are longer and thinner, often absorbed as the permanent teeth start to erupt.

Dental Care

Dental care for primary teeth is important as they are susceptible to cavities and gum disease. Regular dental check-ups, proper brushing and flossing, and a balanced diet can help maintain the health of primary teeth until they are naturally lost.
