Tooth repair, for a child, should generally not be done during the first visit to the dentist. Unfortunately, many times parents bring a child when he already has deep caries and pain.
Then already, we have to react immediately. Since we expect a painful intervention, it is necessary to animate parents and children to accept the anesthesia. That way, the intervention will be less unpleasant and we will be able to finish it by the end.
If we have the conditions to place the seal, then we do it mainly with glass ionomer fillings with fluorine and strontium, which bond well in a humid environment and, due to their composition, have a preventive effect. These fillings must be inspected every 6 months.
