The hardest substance in the human body is the teeth. They are used for chewing and speech. The teeth are found in the mouth and 32 in adults. We are going to take a look at the parts and components of the different types of teeth.
Parts of teeth
The enamel is the outermost part of the tooth. It is white and very hard to protect the inner tooth. It is made of calcium and phosphorus minerals that make it very hard. The dentin is the part under the enamel. The dentin is not as hard as the enamel due to its pores. It is able to detect heat and cold due to its sensitive nature when the enamel is damaged. The pulp is the innermost layer. It is a soft tissue that contains nerves and blood vessels. The teeth have the cementum that binds them to the jawbone and gums. The periodontal ligament holds the teeth firmly to the jaw.
Types of Teeth
An adult mouth has 32 teeth without wisdom teeth. The incisors are eight, four on each jaw. They are the teeth at the front of the jaw. The canines are four with two on each jaw after the incisors. The premolars are eight with four on each jaw. They follow the canine on the jaw. The molars are the teeth at the end of the mouth and are eight. They are four on each jaw. The others are wisdom teeth that are four with two on each jaw.
Some conditions may affect the health of the teeth. Cavities are bacteria that have damaged the structure of the teeth. They occur due to poor brushing of teeth. Gingivitis is the inflammation of gums' surface. The condition occurs due to the accumulation of plaque. Plaque is the sticky film that accumulates on the surface of teeth because of poor oral health. Tartar is the hardened plaque that has mixed with minerals
Brushing teeth once a day should be the best way to keep them clean. Regular flossing and visiting the dentist for checkups help keep the teeth healthy. Visit us for checkups and dental appointments.
