What Are Anterior Teeth? Anterior teeth include the central and lateral incisors and the canine teeth. They make up the six upper and six lower front teeth. The anterior teeth are the teeth that are most visible when a person smiles, and they are also among the first baby teeth to be lost and replaced by permanent adult teeth.

Dental Anatomy In both high-crowned and low-crowned teeth, the tooth is attached to a socket in the jaw bone called an alveolus. The attachment is through a fibrous capsule called the gomphosis. Remembering the term gomphosis is required only of dental students.

- Teeth, as they exist in the mouth, can be placed into any of three broad groupings, the maxillary or mandibular, right or left, anteriors or posteriors. These groupings apply to both the natural dentition and to artificial teeth:

Anterior nasal aperture The anterior nasal aperture (piriform or pyriform aperture) is a heart-or pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose.

TEETH Before beginning the study of the teeth themselves it is necessary to define some terms that are basic to learning about dental anatomy. 1  Human Dentition – The teeth that are located in the upper and lower jaws are collectively referred to as the human dentition. 2  Maxillae – The upper jaw is known as the maxillae.

- There are several types of teeth. Incisors are the squarish, sharp-edged teeth in the front of the mouth. There are four on the bottom and four on the top. On either side of the incisors are the sharp canines. The upper canines are sometimes called eyeteeth or cuspids. Behind the canines are the premolars, or bicuspids.

Animal Dentistry & Oral Surgery Specialists LLC In viewing the teeth from the side with the mouth closed, the premolar teeth of the upper and lower dental arcades interdigitate very much like the teeth of a sheers scissors (see photo above). Additionally; the upper fourth premolar tooth, overlaps the lower first molar tooth.

- In most species, canines are the anterior-most teeth in the maxillary bone. Narwhals provide an extreme example, where one canine tooth, usually the left, erupts into a long spiral horn up to nine feet (2.7 metres) long. The four canines in humans are the two maxillary canines and the two mandibular canines.

Dental Occlusion Protrusive movement: the anterior movement of the mandible. as the mandible moves anteriorly, the posterior teeth disarticulate. this is known as ANTERIOR GUIDANCE. the maximum posterior disarticulation occurs when the anterior teeth are EDGE to EDGE. Anterior guidance depends largely on the HORIZONTAL and VERTICAL relationship of the maxillary and mandibular incisors and canines. Cusp length varies on the extent of this relationship.

- Teeth names locations are in each quadrant of the mouth. Each of the quadrants contains 8 permanent teeth namely: 2 incisors, 1 cuspid, 2 bicuspids and 3 molars. The central incisor is located to the side of the midline because it is centrally placed in the arch. Beside the central incisor is the lateral incisor.

- The dental formula for primary teeth is 2.1.0.22.1.0.2. In the primary set of teeth, there are two types of incisors – centrals and laterals, and two types of molars – first and second. All primary teeth are normally later replaced with their permanent counterparts.

Dental anatomy In deciduous teeth, the maxillary second molar is the last tooth in the mouth and does not have a third molar behind it. The deciduous maxillary second molar is also the most likely of the deciduous teeth to have an oblique ridge.

Teeth Numbers and Names: A First Step in Understanding Your Treatment Plan As shown in Fig. 1 above, the ADA teeth numbering system treats the 32 permanent teeth in a clockwise fashion as seen by your dentist. Teeth numbers 1 – 16 are on the upper jaw. Teeth numbers 17 – 32 are in the lower jaw. As an example, teeth numbers 1, 16, 17, and 32 are your wisdom teeth. Teeth numbers 14 and 15 are your upper left molars.

Picture of the Teeth A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13: • Incisors (8 total): The middlemost four teeth on the upper and lower jaws. • Canines (4 total): The pointed teeth just outside the incisors. • Premolars (8 total): Teeth between the canines and molars. • Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food. • Wisdom teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth. The crown of each tooth projects into the mouth.

Deciduous teeth Deciduous teeth. Baby teeth redirects here. For other uses, see Baby teeth (disambiguation). Deciduous teeth are now more commonly known as primary teeth. They are also known as baby teeth, temporary teeth and milk teeth. They are the first set of teeth in the growth development of humans and other diphyodont mammals. They develop during the embryonic stage of development and erupt—that is, they become visible in the mouth—during infancy.

Elephant Teeth Asian elephants teeth, in contrast, have a compressed diamond-shaped lamella profile that are adapted to the elephant’s diet of grasses, trees, shrubs and bark. Their teeth work by moving in a forwards and backwards motion, grinding down plant material.

Canine tooth In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, fangs, or (in the case of those of the upper jaw) eye teeth, are relatively long, pointed teeth. However, they can appear more flattened, causing them to resemble incisors and leading them to be called incisiform.

- Males of a few species possess enlarged, tusk-like upper canines (Hydropotes, Muntiacus, Elaphodus). In other species the upper canines are either vestigial or absent. The dental formula is thus I 0/3, C 0-1/1, P 3/3, M 3/3 x 2 = 32-34. The molars are selenodont, and usually brachyodont. There are usually two lacrimal canals. Females usually have two pairs of mammae, and the young of most species are spotted. There is no gall bladder.

- Inferiorly, the alveolar process of the maxilla houses the teeth, including central incisors, lateral incisors, canines, 2 premolars, and 3 molars in adults. The tooth roots form vertical, wavelike eminences in the anterior face of the maxilla; the canine root is the most prominent.

Teeth Names & Numbers Each quadrant of the mouth has 8 different teeth that are mirrored horizontally and vertically to the other quadrants. In the FDI notation each one of these 8 teeth is assigned a number from 1 to 8, starting from the center front tooth (central incisor) and moving backwards up to the third molar (number 8).

Anatomy of a Mouth For the back teeth (molars and premolars), the area that faces the cheeks is called the buccal surface, and the biting (chewing) area is called the occlusal surface. There are different types of permanent teeth, each of which performs a specific function. Central Incisors: The central incisors are the front teeth.

Exposure of Unerupted Teeth The upper cuspid (upper canine/eyetooth) is the second most common unerupted tooth. The cuspid tooth is a critical tooth in the dental arch and plays an important role in your bite. The cuspid teeth are very strong biting teeth and have the longest roots of any human teeth.
