Dental caries

The cavity is the main reason for seeing the dentist.
In fact, tooth decay affects all ages and early intervention is needed to avoid degradation of the tooth in question.

But what is a bunt?
The decay is the disintegration and dissolution of tooth enamel and dentin.
The damaged area on the tooth takes on a dark color.
Caries is the disease's most frequent, 95% of Europeans have decayed teeth.



SYMPTOMS
Hole in the enamel and dentin
Brown tint
Pain
Sensitivity to hot, cold and sugar.

Flora important is housed in the mouth, consisting of a hundred species of bacteria and fungi, made through the air, drinks and food.
This flora is normally provided to protect the health of the oral cavity, but it contains within it some pathogenic varieties that await the time to proliferate.
Among them are cariogenic bacteria, whose species is the most aggressive streptococcus mutans, which transformed the sweet acid can attack the calcium in tooth enamel and dentin dig (known ivory) to the dental pulp.
Sugary foods are not solely responsible for the development of caries.
Other factors such as poor diet, the amount of saliva (unless there is more cariogenic bacteria grow) and its acidity, the quality of the enamel depends on the state of mineralization of the individual episodes of fatigue and illness, pregnancy, nursing, dental plaque and tartar where microbes found refuge, a poor dental hygiene and poor chewing may also be involved.



Evolution of caries

The evolution of a cavity has been slow. It is initially painless.
When bunt moved within a tooth, it becomes sensitive to the pressure'abord (avoid chewing on the side of the tooth cariée), followed by hot and cold.
When it really hurts, it means that the decay has reached the dental pulp is innervated.
Most cavities develop at the neck (for the gums), where plaque accumulates in the grooves on the surface of molars, in areas of interproximal contact.
This means that all places accessible by brushing.
That is when the cavity is still painless it is better to seek treatment, hence the importance of regular visits to the dentist to stop the work of bacteria responsible for dental injuries.
The care of oral health depends on individual initiative, but the deep cleaning of the affected part and filling, under the jurisdiction of the dentist.
If the instruments used in dentistry are more precise, more powerful and more smooth and that injections of anesthetics have become more frequent, vibration and noise of the wheel are always unpleasant.
Dental care is still a source of apprehension for the patient.

The surgeon proceeded in stages.
As a first step, it must widen the tooth to extract the cariée all damaged tissue, soft, invaded by bacteria, and make clear the gap, clear, clean, fit to receive a dressing disinfectant odor and the taste of clove.
In a second step, it must close the tooth with an amalgam or composite material.

But which one to choose?

The mercury amalgam

Formerly it was called sealing.
It contains at least 50% of mercury, a soft metal which are incorporated nickel, silver, copper, tin.
His plasticity facilitates the installation and its adherence to the walls of the tooth.
His strength is good and its cost is modest.



Composite materials

Composite materials are newer than amalgam.
They contain particles of glass, ceramic or zirconium integrated into a synthetic resin.
They do not contain mercury.
Their resistance is lower pressure, acidity and wear faster.
In addition, they easily fit under the relief of the dental cavity which can make the filling of the tooth and sealing more random.
They called for strict drying, hard finish.
As for cost, it is a little higher.


The gold fillings or ceramics.

There are also gold fillings or ceramics.
Ceramic is reserved for front teeth because it is too fragile to be used in the restoration of molars and premolars.
Gold and ceramics are used in a technique known as "inlays," tailor-made teeth.
The dentist makes a mark of the dental cavity to send to a dental prosthesis that will flow into the material the documents. Then the inlay is tested and determined in the cavity with a special cement.
In contrast, there are "onlays, which are used but also poured out of the tooth in the form of a crown for example.
This type of filling is more expensive, especially when gold.
A final possibility is a dental cement called cement stone.
Non-metallic, of various (mostly made of silica and phosphate), low resistance to commonly used for fillings temporary, pending a lasting solution.



What can you do yourself to prevent tooth decay?

It is important to have good dental hygiene.
Brush teeth for 3 minutes is required after every meal.
It is vital not remanger brushing after the last of the day.
It should also regularly clean the space between the teeth using dental floss.
Food can also have healthy teeth.
Indeed, food and wine farms, chewed completely, clean teeth.
Minerals and trace elements reinforce each other.
The whole grain bread is healthier than white bread.
We must correct the wrong position of the teeth (orthodontics).
Fluoride helps strengthen the enamel. In Switzerland and the United States, fluoride is added to drinking water, and found in these two countries a decline in dental caries.
Infants up to two years receive a supplement of fluoride, often associated with vitamin B, in the form of tablets issued by the pediatrician.
There are also toothpastes, solutions, chewing gums and table salt containing fluoride.



Evolution caries

A tooth can contaminate cariée tooth neighbor.
In the case of destruction of enamel, the bacteria get into the gum and then in the flesh, leading to inflammation of the tooth (pulpits).
The small dots of decay time treaties are safe.
But inflammation total tooth can lead to a serious deterioration of health, such as heart disease or rheumatism.



Cavities in children

The lack of dental hygiene leads to an average of two cavities in six years, four to ten years.
We must not think that caries of primary teeth are unimportant.
Hygiene habits should be acquired as soon as teeth appear.



Brushing teeth correctly

Use a brush with a small head.
Brush first molars from the bottom up, in a circular motion on the inside and outside, then the incisors.
