What is tooths or teeths?

Teeth or tooths (plural) are hard, calcified structures located in the jaws of most vertebrates. Teeth have various shapes and sizes depending on their role in the mouth. They are used by animals for biting, chewing, and grinding food, as well as other functions such as communication, self-defense, and grooming.

Humans have two sets of teeth in their lifetime: the primary or baby teeth, and the secondary or adult teeth. Primary teeth start developing before birth and usually erupt between 6-12 months of age. They are eventually replaced by adult teeth between the ages of 6-12 years.

Adult teeth consist of 32 teeth in total, with four types: incisors, canines, premolars, and molars. Incisors are located in the front of the mouth and are used for cutting food, while canines are pointed teeth used for tearing and gripping. Premolars and molars are large, flat teeth used for crushing and grinding.

Teeth are composed of several different layers: the enamel, dentin, cementum, and pulp. Enamel is the hard, outer layer of the tooth that protects the inner layers from damage and decay. Dentin is a softer layer located beneath the enamel, while cementum covers the tooth root. The pulp is the soft, innermost layer that contains nerves and blood vessels.

Taking good care of your teeth is important for overall oral health. Proper dental hygiene includes brushing and flossing regularly, as well as visiting the dentist for checkups and cleanings.
