How many teeth does a person have?
Ideally, a person has 32 teeth, but many people have no wisdom teeth or other teeth that were not placed in the dentition. It can also happen that a human set of teeth consists of more than 32 teeth.
The human dentition has 32 teeth
- A person usually has 32 teeth. This also includes the wisdom teeth, which are missing in a relatively large number of people. Other teeth can also be missing because they were not created at all; in medicine this is called hypodontia or, if more than five teeth are missing, oligodontia. The opposite, i.e. more than 32 teeth, is also possible, but this rarely happens.
- A distinction is made between incisors, canines, premier teeth and molars. In the front you have four incisors in the lower and upper jaw, followed by a canine, two pre-grinding teeth and three grinding teeth.
- Perhaps you have already wondered what the numbers are that a dentist dictates to his assistant while he is talking to you mouth looks. It works as follows: To avoid confusion and end up treating the wrong tooth, dentists divide your teeth into four quadrants. The teeth on the top right are numbered one, on the top left number two, on the bottom left number three and on the bottom right number four. That makes eight teeth per quadrant, which are numbered from one to eight from front to back. According to this system, the third tooth on the top right has number one-three.
- As in other medical fields, in dentistry the question of where is left and right is seen from the patient's point of view.
A tooth is made up of many parts
- Each tooth consists of the tooth crown, the tooth neck and the tooth root, they are each made up of several layers. However, if everything is fine with your dentition, you will only see the enamel on the crown of the tooth, which is extremely hard and is the hardest part of the human body.
- Beneath the enamel lies the dentin, which is softer than the enamel and is therefore more susceptible to tooth decay. This is where the Toothachebecause the dentine is sensitive to stimuli.
- The pulp, through which blood vessels and nerve fibers run, is located right inside the teeth. They are used to care for and nourish the teeth.
- The tooth neck connects the tooth crown with the tooth root. You usually don't see it because it's covered in gums. However, when the gums recede, exposing the neck of the tooth, they are very sensitive to cold or hot food and drinks or other stimuli.
- So that the teeth have a good hold, they are firmly anchored in the jaw with the tooth roots. These roots are about twice the length of the tooth crown. Depending on the type of tooth, it can have one or more of these roots. Wisdom teeth have a particularly large number of roots, which also often have an irregular shape. Because of this, wisdom teeth are poorly treated and often pulled when they cause problems.
Proper care of the teeth is of the utmost importance for keeping the teeth healthy ...
