Human tooth

Human tooth refers to one of the hard, calcified structures found in the mouth of many vertebrates. In humans, teeth serve primarily for masticating food, but also have secondary roles in speech and facial appearance.

Anatomy

The human tooth consists of three main parts: the crown, the neck, and the root. The crown is the visible part of the tooth, while the neck and root are embedded in the gum and jawbone respectively.

Crown

The crown of the tooth is covered by enamel, the hardest substance in the human body. Beneath the enamel is the dentine, which forms the bulk of the tooth structure.

Neck

The neck of the tooth is the part that connects the crown to the root. It is covered by the gum and is not usually visible.

Root

The root of the tooth is embedded in the jawbone and is not visible. It is covered by cementum, a hard tissue that helps to anchor the tooth in the bone.

Types of teeth

Humans have four types of teeth: incisors, canines, premolars, and molars. Each type has a specific function in the process of mastication.

Incisors

Incisors are the front teeth. They are used for cutting and chopping food.

Canines

Canines are the pointed teeth located next to the incisors. They are used for tearing food.

Premolars

Premolars are located next to the canines. They are used for crushing and grinding food.

Molars

Molars are the largest teeth. They are located at the back of the mouth and are used for grinding food.

Dental health

Maintaining good dental health is important for overall health. Regular brushing and flossing, along with regular dental check-ups, can help prevent tooth decay and gum disease.
