Can cavities be filled?

When tooth decay occurs, it must be repaired in time to prevent it from spreading. If tooth decay is allowed to develop, it will also cause damage to other teeth. When repairing tooth decay, you must understand some precautions and go to a professional hospital for treatment to avoid unqualified medical equipment and disinfection equipment in some small clinics, which may cause adverse effects on your health.

Tooth filling steps

Oral examination Before filling a tooth, the dentist will conduct a comprehensive examination of the patient's oral cavity, have a comprehensive understanding of the patient's oral health status and deal with it appropriately, and develop the best filling and restoration plan based on the number of caries, treatment sites, and the severity of caries in the patient.

Cavity preparation

The cave is composed of cave walls, cave edges and cave corners.

The principles of cavity preparation are:

① Remove all diseased tissue, otherwise it will cause secondary caries; ② Protect the dental pulp and healthy tooth tissue; ③ Establish a good retention shape (i.e. a shape that can keep the filling in the cavity without falling off or loosening) and resistance shape (i.e. a shape that can withstand chewing force without causing the filling or tooth to break) to prevent the filling from breaking, falling off, or not fitting tightly and causing secondary caries.

Cavity disinfection

When the cavity is prepared, it needs to be fully and thoroughly disinfected. Depending on the severity of caries lesions, the disinfection time for different caries varies greatly. If it is early caries, only a one-time disinfection is required to fill the filling material; if it is moderate or deep caries, three to five sealing treatments are required; and if the dental nerve is involved, root canal treatment is required first.

Filling

Isolate saliva, disinfect the cavity, prepare filling materials and fill them into the cavity, and sculpt the shape immediately. Be careful to remove the part that exceeds the occlusal surface to avoid iatrogenic occlusal trauma. There should be no overhang of fillings on the adjacent surfaces to avoid irritating the gums and causing inflammation.

Treatment after filling

After filling the tooth, the dentist will polish the surface of the filling to prevent the filling material from staining, and will promptly clean the residue remaining on the tooth surface and in the mouth after the filling. Some patients have larger caries and need crown repair after filling. At the same time, the dentist will give the patient detailed medical instructions.
