The root of a tooth descends below the gum line anchoring the tooth in the mouth..
cusp – The top portion of the tooth; the tip or point. deciduous teeth – The first set of teeth, also known as primary teeth. dentin – The tissue of the tooth between the pulp and the enamel and cementum; the majority of the tooth. dentition – A set of teeth..
Landmarks meanElevations, depressions and grooves are present on the surfaces of teeth, and different terminologies are used to describe these landmarks.
