Tusks are not present in the human dentition. They are characteristic of certain animals, such as elephants and wild boars.

Incisors are designed for cutting and slicing food due to their sharp, chisel-like edges.

Canines are commonly referred to as eye teeth, corner teeth, and fangs due to their position and shape.

Premolars are commonly referred to as bicuspids, false molars, and transitional teeth due to their location and function.

Molars have large, flat surfaces with cusps and ridges, which are designed for grinding and crushing food.

Enamel is the outermost, hard, and mineralized layer of the tooth crown, providing protection and strength.

Dentin is the layer beneath the enamel, forming the majority of the tooth structure and providing strength and support.

The pulp is the innermost layer of the tooth, containing blood vessels, nerves, and connective tissue, which provide nourishment and sensation.

Cementum is a mineralized tissue covering the tooth root, providing attachment to the periodontal ligament and supporting the tooth in the jawbone.

The periodontal ligament is a specialized connective tissue located between the cementum and alveolar bone, providing support, cushioning, and proprioception to the tooth.

The gingiva is the soft tissue surrounding the teeth, providing protection and support to the underlying structures.

The alveolar bone is the specialized bone that supports and anchors the teeth in the jaw.

Saliva has multiple functions, including digesting food, lubricating the oral cavity, and neutralizing acids, among others.

Dental caries is a multifactorial disease caused by the interaction of bacteria, sugar, and acid in the mouth.

Dental hygiene aims to prevent tooth decay, gum disease, and maintain a healthy oral environment, promoting overall oral health.
