The aim of dental treatment is to try to keep the teeth in one’s mouth by eliminating pathologies (caries, granulomas, gum problems) in the least invasive way possible. Aesthetics is also an important element and the restored tooth must be the same as a healthy tooth. It is also possible to easily improve the aesthetics of the teeth with small changes thanks to the new materials used in the study (composite and ceramic veneers).
Doctor Zorzenon, Doctor Zannier and Doctor Panseri dedicate themselves to this discipline.
Caries is eliminated by keeping all the healthy part of the tooth. The cavities are filled with material of the same color as the tooth and shaped so that they are invisible. With the same materials, missing parts of the teeth themselves can be reconstructed or the entire surface of the damaged tooth can be reconstructed.
When the destruction of the tooth is very extensive, in particular in the areas subjected to strong chewing loads such as on the posterior teeth, products created in the laboratory are used, after taking an impression of the appropriately prepared cavity. Also in this case the result is such as to obtain a tooth that cannot be distinguished from a natural tooth. The dentist will evaluate which is the best solution in the individual case.
Root canal treatments
When a tooth dies inside, the “pulp” or “nerve” remains, which decays. The harmful products coming out from the apex of the tooth root create a reaction of the organism called “granuloma” which destroys the surrounding bone. Sometimes the lesion is discovered on x-rays, sometimes there is pain when chewing on the tooth, sometimes there is severe pain and an abscess with swelling may develop. To cure these problems, the inside of the root must be cleaned. The techniques used in our studio follow the most modern guidelines, preserving the structure of the tooth to the maximum, working with the most modern instruments in an aseptic environment, almost always managing to heal the “granulomas”, saving the tooth itself.
What is tooth decay?
Caries is a tooth disease that involves the progressive loss of tooth substance.
What is the cause?
There are two main causes of tooth decay: certain types of bacteria present in bacterial plaque, and refined sugars introduced in the diet. Cariogenic bacteria use sugars and produce acid which affects the surface of the tooth.
Other factors can increase the risk of tooth decay, such as diseases, drugs or therapies that reduce saliva production (it is important to report these at the time of the first visit), eating disorders (anorexia and bulimia), digestive disorders.
What happens to the decayed tooth?
Caries begins as a small opaque, white, chalk-like spot on the surface of the enamel, and then deepens to the underlying layer, the dentin.
The carious dentin softens and a real cavity is formed, which if not treated continues to increase causing the fracture and the loss of entire parts of the crown, up to the possible loss of the tooth.
Initially there are no particular symptoms, then as the caries progresses the tooth can become more sensitive to cold and sweet foods and drinks, it can hurt by chewing when food enters the cavity, there may be inflammation and bleeding of the gum close to the caries, pain with hot food and drink and therefore spontaneous pain when the caries is very deep and there is inflammation of the pulp (the “nerve” of the tooth).
In many cases, however, the symptoms are very mild, and a deep caries can be completely asymptomatic: it is therefore advisable to have periodic checks and not only when a disturbance is felt.
How is it treated?
The decayed tooth must be treated as soon as possible. In the initial stages, when the caries is still only in the enamel, remineralizing treatments can be made that manage to stop or slow it down, then keeping it under periodic control.
When the caries reaches the dentin, an intervention is necessary: the carious part is eliminated, leaving a completely cleaned cavity in the tooth. This cavity is filled with the composite material by reconstructing the missing part in order to recreate form, function and aesthetics. When the caries is very extensive and the healthy part of the tooth is excessively weakened, an indirect reconstruction may be preferable, that is done by the dental technician in the laboratory on the exact model of the tooth, and then “glued” on the tooth (composite or disilicate inlay ).
When the caries is very deep and especially if there are important symptoms it may be necessary to perform root canal therapy. But treating a decayed tooth does not mean treating the “caries disease”: in fact, the causes must be eliminated with proper oral hygiene and correct eating habits by following the advice of the dentist and the hygienist.
How is caries discovered?
During the visit and the checks, the dentist and the hygienist carefully examine all the visible parts of the teeth, also with the help of magnification systems, and identify the caries of these surfaces.
But there are areas that are not directly visible, such as the surfaces of the tooth in contact with neighboring teeth, or the parts under a filling: intraoral radiographs performed directly on the chair (in particular the bite-wing x-rays) allow to discover decay of these hidden surfaces and should be done when the dentist deems it necessary.
In our studio we also use a particular lamp equipped with a transillumination tip, which is a valid diagnostic aid for the visualization of interproximal caries and fractures, without having to resort to radiography.
