Cutting, tearing and shearing the food is the first process of digestion. This can be with the help of saliva supplied by salivary glands, it works as lubricants.

Development of Teeth
Teeth start growing in the foetus. Excellent nourishment from the mother in pregnancy is essential in the growth and development of the teeth. The mother’s diet plan must have sufficient quantities of calcium, phosphorus, vitamin C, as well as vitamin D. The initial phase commences in the foetus at approximately five to six weeks of age. This is exactly the moment the fundamental ingredient of the tooth forms.
The tough tissue that surrounds the teeth is produced, around three to four months of gestation. After the little one is delivered, the subsequent phase takes place when the tooth in reality protrudes through the gum. Lastly, there will be the loss of the primary “baby” teeth. Adult teeth start to develop between the age of six years and twelve years. The primary teeth are 20 while the permanent teeth are in most cases 32.
Parts of the Tooth
A tooth is divided into two basic parts: the crown & the root. The visible part & white part of the tooth is called as the crown, and the root is the one which cannot be seen. There are four kinds of tissues in the teeth. These include:
- Enamel is the substance that covers the tooth crown. It is harder than bone and enamel protects the crucial tissues within the tooth. Enamel is prepared up of hydroxyapatite, phosphorous, and calcium.
- Dentin is found underneath the enamel, which is calcified and looks like a bone. Dentin is not as hard as enamel, so there is a greater risk for decay if the enamel wears away.
- Cementum is of light yellow colour and is usually covered by the gums and bone. It covers the tooth root and helps affix it into the bone. This tissue is quite softer in comparison to enamel and dentin.
- Pulp is originated at the centre the tooth and it has the blood vessels, soft tissues and nerves. It delivers nutrients and signals to your teeth.
