The black lines are staining due to food deposits etc and are perfectly normal. They often have slightly yellow teeth too. It is a good idea to check their teeth regularly to ensure they are not getting too long.
Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. Tooth formation begins before birth, and teeth's eventual morphology is dictated during this time. Dental anatomy is also a taxonomical science: it is concerned with the naming of teeth and the structures of which they are made, this information serving a practical purpose in dental treatment. Usually, there are 20 primary ("baby") teeth and 28 to 32 permanent teeth, the last four being third molars or "wisdom teeth", each of which may or may not grow in. Among primary teeth, 10 usually are found in the maxilla (upper jaw) and the other 10 in the mandible (lower jaw). Among permanent teeth, 16 are found in the maxilla and the other 16 in the mandible. Most of the teeth have distinguishing features. Thanks

The same ones as the primary anterior teeth: Canine, lateral incisor, central incisor.
Anterior has four surfaces while posterior has five.
incisal
The word over jet is used in dentistry to describe the distance between teeth. Often the distance between the maxillary anterior teeth and the mandibular anterior teeth are the ones used for this distance.
the canines and the teeth between the canines
The area that appears only on the anterior part of a body include beard and teeth. The teeth are only found on the mouth.
First Molar :)
The raised area on the lingual surface of anterior teeth is called the cingulum. It serves to provide structural support to the tooth and can vary in size and shape among individuals.
serratus anterior
There are a total of eight anterior teeth in the permanent dentition: four incisors and four canines.
yes.. anterior theeth have pulp horn... all anterior theeth have 2 pulp horn except maxillary central incisors have 3 pulp horn...
