The teeth perform a mechanical function, which is used to breakdown the food items in the way of crushing, cutting in preparing of digestion, and as well as swallowing. There are near four classifications in teeth, they are incisors, molars, canines, premolars. Every classification has a specific functionality.
- Incisors- This is the first classification in teeth, which is used to cut the food items.
- Canines- the second classification, this used to tear food items
- Premolars and molars -Used in purposing of crushing the foods.

Diphyodont
Humans such as mammals usually diphyodont, which refers to a developed set of teeth. The deciduous set is also known as primary, baby, milk, and first set. This appears to be in the first six months of mammals or humans. Some babies used to bear with visible teeth called natal teeth. Teething is an eruption of a tooth which causes more pain.
Development
The development of a tooth is a complex stage. They form an grow, erupting of mouth, cells of embryos. Although they used to have many species in teeth, the development will be the same in humans. The human teeth should have a healthy environment, cementum, enamel, periodontium, and dentin. Teeth that grow primarily develops from the embryo between 6-8 weeks. Teeth in a permanent way which forms in 20 the week. The tissues like the pharyngeal arch are used for the development of teeth.
Stages
The development of the tooth is classified into four stages, they are bud, cap, bell, maturation. The bud is also known as tooth germ is due to cell aggregation in forming a tooth. It gets subdivided into three parts the dental follicle, dental papilla, enamel organ. Enamel is an outer epithelium, stellate epithelium, inner epithelium, stratum intermediation. These types of cells give rise in ameloblasts, produces enamel, reduction in the epithelium. This follicle arises to cells in three stages, osteoblasts, fibroblasts, and cement oblasts.
- Cement oblasts gives formation in cementum.
- Osteoblasts arise in the alveolar bone around the teeth.
- Fibroblasts are used to develop the ligaments in periodontal, which connects in teeth to alveolar bone from cementum. The papilla consists of cells in the development of odontoblasts, this helps in forming cells. Papilla and enamel epithelium determine the shape of the tooth. The sections in developing the tooth, that may appear in the classification of stages.
Eruption
When the eruption occurs, the mouth becomes visible longer. The research used to indicate the ligaments a role in the eruption of the tooth. The combination of permanent and as well as primary is called a mixed stage. The stages, last as long as the primary teeth are last, remaining teeth interrupts in the mouth. There are many theories based on tooth eruption, development of teeth, etc… the wide belief is the ligaments that provide an impetus.
The tooth in primary condition has attached to psychological criteria and in somatic tissues. There is a purpose in developing root pulses in the tooth which pushes into the mouth. The development of a tooth is very difficult, mainly in stages.
