Tooth :

A tooth is a single structure in the human mouth. It is composed of several layers, including the enamel, dentin, pulp, and cementum. Each tooth has a specific shape and function, such as biting, tearing, or grinding food. The roots of every tooth are covered by gum. The tooth is not made up of bone, but rather it is made of multiple tissues of varying density and hardness that originate from the outermost embryonic germ layer,  called the ectoderm.

The word “tooth” originated from two old languages called Proto-Germanic and another very old language Proto-Indo-European. The word “tooth” was made up of two parts: the root word “*h₁ed-” which means “to eat”, and a suffix “-nt” which means “something that does”. So, the word “tooth” literally means “something that eats”.

The tooth is used in a singular form, for example – ” I accidentally bit down too hard and chipped my tooth. ” in this sentence, a person is referring to a particular tooth. Similarly, the word toothache means – pain in a particular tooth.

The tooth is composed of four different types of tissue: enamel, dentin, cementum, and pulp. 

• Enamel is the outermost layer of the tooth and it is the hardest substance in the human body. It protects the underlying layers of the tooth and helps prevent tooth decay and cavities.
• Dentin is the layer of the tooth beneath the enamel. It is a yellowish material that is softer than enamel but harder than bone. It provides support for the enamel and is responsible for the color of the tooth.
• Cementum is a layer of connective tissue. It covers the root of the tooth and helps to anchor the tooth to the jawbone.
• Pulp is the soft tissue inside the tooth that contains nerves and blood vessels. It provides nutrients and oxygen to the tooth and helps maintain its health.
