Your teeth
Why do you need teeth??
To eat, of course! Without teeth we would have problems nourishing ourselves. Your teeth chew what you eat to a pulp. This facilitates the work of the stomach. If we do not chew our food properly, we may get stomach aches or even get really sick.
We also need our teeth to speak. The letters D, N and T would be difficult to pronounce without teeth. They are therefore also called tooth sounds.
But we also need our teeth to look good. They are part of our personality. Everyone sees them when we smile. Nothing is worse than not being able to smile openly because you are ashamed of your teeth. Beautiful teeth make a smiling smile!
The history of the teeth
When you were still in the stomach
Your teeth began to form during the seventh week of pregnancy. Since you were just 1.5 cm tall.
Around the fourth month of pregnancy, your tooth germs are the same as a small bell. They contained several cells with information about color and shape.
The germs were built by various minerals from the blood, such as calcium and fluoride.
The milk teeth
The first tooth appears at the age of about six months. But he can come at four months and sometimes it takes a year or more.
Before your tooth broke, it grew in the gum. It swelled, became red and sensitive. You drooled and you were whining. To make it less painful, your parents gave you soft toys, cloths, teethers and rubbers.
The first tooth that breaks through is usually the lower central incisor, followed by the lateral lower and upper incisors.
Between the 12 and 18 months of life, the first molars broke through. Then it was the canines’s turn. Finally, the second molars came, with about 2-2.5 years.
This means that at the age of about 2.5 years you had a total of 20 teeth, ten at the top and ten at the bottom.
The permanent teeth
Three months after birth, the tooth germs of the permanent teeth began to grow in the jaw. Gradually, they needed more and more space and dissolved the roots of the deciduous teeth. At about six years old, the first baby teeth fell out.
The entire change of teeth takes place between the sixth and the twelfth year of life. In adulthood, ie between the ages of 18 and 25, then come the teeth of the teeth.
Once the teeth are there, they will not grow any longer. The jaw itself, however, grows with the face.
Biting and chewing uses the teeth. When the incisors break through the gums, they have sharp edges. Gradually, they blunt. Some people go faster, the others slow down, depending on what food we eat.
What does the tooth consist of??
A tooth is hard on the outside and gets softer and softer on the inside. Of the enamel is the hardest substance in our body. It covers the tooth crown and becomes thinner and thinner towards the gums.
Under the tooth enamel is the dentin. It is interspersed with fine channels and connected to the pulp.
The pulp is very soft and very sensitive. It is interspersed with nerves, blood vessels and lymphatic vessels.
In your mouth, the teeth seem to be well protected. Nevertheless, they are exposed to many attacks.
Of the plaque For example, there is a fine, soft, white coating that is on the surface of the teeth. This deposit contains many bacteria that feed on the remnants of the food.
If the plaque remains on the teeth longer, forms the tartar. The tartar irritates the gums, it swells, we red and starts to bleed. This is a sign of gingivitis.
The bacteria in the plaque, caries and inflamed gums creates an unpleasant odor in the mouth, the halitosis.
The soft plaque you get away with your toothbrush very well. The tartar removes your dentist, quickly and easily.
What is caries??
Caries is caused by acid attacks on the surface of the tooth. In the beginning, only the enamel is affected, later it penetrates to the dentin and causes pain.
If the tooth is not treated now, the bacteria penetrate all the way to the pulp and then down to the bone. The pain is then unbearable.
In this case, the dentist will clean the tooth and provide it with a filling. So the tooth is well protected and you can bite everything again.
What does a filling consist of??
You can think of the stuffing as a kind of putty that the dentist stuffs into the cleaned hole in your tooth so that no leftovers or bacteria get in. In children and adolescents, it is usually made of a special, tooth-colored plastic. It has the advantage that it can be processed very easily and quickly. At the end of the treatment, you will not even see where the tooth has been repaired.
