The filling is still called this, even though it does not contain lead. This is a dentist’s material to fill the teeth’ cavities when part of the teeth has been removed, for example, due to decay.
A filling is a part of caries treatment. When a patient has cavities, the dentist will be able to assess the damage to the dentition. Its objective will be initially to preserve as much as possible the dental pulp and preserve the vitality of the tooth.
After removing the decay, the dentist will clean the cavity and then perform a protective treatment before installing the amalgam or composite cement. This pose will fill the space created by eliminating decay and restore the shape of the tooth.
He removes the affected tooth tissue with a small portable grinding wheel (called a bur). It cleans the cavity up to the healthy part of the tooth.
Then he closes the cavity with an inert product (“filling”) that does not react with the body: an amalgam or composite resins, for example.
When the decay is intense, it is necessary to devitalize the tooth (remove the pulp in the center). The dentist may have to block the canals of the tooth.
If he notices an abscess or a deep infection, he will prescribe an antibiotic treatment, after which he can intervene on the tooth. This is because the infection causes inflammation of the tissues, making them difficult to treat without causing bleeding.
While no type of filling has been proved to be permanent, some dental filling does last longer than others:
While they are severe and don’t need to be changed for ten years, they’re also more expensive. The aesthetic aspect is also essential since it allows the tooth to have a natural appearance, but it also helps maintain the tooth’s vitality, unlike the crown.
Since the guide for the use of sealants in 1986, we have seen the emergence of new facts concerning caries’ epidemiology, these clinical characteristics, the probable thresholds for demineralization of a caries lesion, the techniques of caries, diagnosis, and different conservative treatment options.
All this information has resulted in creating a climate of uncertainty.
One of the most frequently cited prejudices is the fear of sealing a cavity that can progress. A few researchers, 22-29, have been interested in the danger of progression of an incipient carious lesion (in the enamel) and have been able to demonstrate that there is no evolution of caries on teeth whose sealing agent is still intact after one year, two years, five years. Thus, it has been suggested that it is possible to stop the lesion’s caries process that has slightly passed the enamel-dentin junction by applying a sealant.
