We feel that the teeth in the mouth are just an ordinary thing in the body. It is essential to know that the teeth occupy a special place in the mouth and work as an essential part of the body. All we see is that the teeth are chewing and cutting the food, but the job of teeth is quite complex. It is an equally essential part in making you smile in an impressive way. If there is any problem you might have to visit the dentists. To sum up it is important to know that teeth are important in all kinds of activities taking place in the oral cavity including eating, smiling, and shaping the whole face region. The role of the teeth is quite evident when people suffering from deformed teeth go for the procedures like invisalign.
The dental anatomy
Teeth are composed of four different layers namely enamel, cementum, pulp and dentin. The hardest among these four layers is the enamel that covers and protects the tooth inside. This is followed by an interior of dentin and then is the pulp. Pulp is the deepest resting layer of any tooth that actually homes the nerves and the blood vessels inside it. The fourth component of the teeth is the root or the Cementum that rests under the gum. It is important to visit the dentists if there is some problem with the Cementum.
The teeth are in different numbers in the mouth with every age. These teeth exist in two sets in the mouth. The first type is the baby teeth or the primary teeth. These teeth get replaced with the permanent or the adult teeth with the passage of time.
Types of teeth
If you are planning to go for any dental procedure like invisalign in chatswood then it is important to know about the teeth and their functionality. The oral cavity has four types of teeth.
- Incisors mean the four teeth that are in the front part of the upper and lower jaw. They are sharp enough and do the cutting job. The two incisors that stand next to the both sides of the midline are known as the central incisors. Adjacent to these are the lateral incisors. They are distinct from other teeth in the mouth as they have just one root while the incisal edge is quite sharp to cut through the foods of all kinds.
- Canines are four in number. They are arranged in such a way that two of them are located in the maxillary arch and the other two in the mandibular region. They are adjacent to the lateral incisors. After the incisors cut through the food these teeth tear the food apart. These teeth have a root longer than the root of other teeth in the mouth. These pointed cusp teeth shape the corners of the mouth.
- Premolars are also known as the Bicuspids. They have a place adjacent to the canines. They crush the food particles that are chewed and crushed earlier. The premolars are eight in number. The eight premolars are divided equally into the four quadrants of the mouth. This means that there are two in each of the quadrant. The first premolar is close to the midline. They have 3 or 4 cusps. The first maxillary premolars have two roots. The rest of the premolars have just one root.
Molars are at the extreme posterior side of the oral cavity. The dentist find it hard to check these teeth. They are broad and flat at the top with a maximum of 5 cusps. The mandibular molars have two roots. Maxillary molars have three roots in total. The total of 12 molars is equally divided into the group of three in the four different quadrants. The third moles are not fully gown.it takes time to grow and they are called the wisdom tooth.
