Preventive dentistry deals with preventing soft and hard tissue diseases inside the oral cavity. Preventive dentistry usually implies dental interventions carried out on children’s teeth to prevent the appearance of caries. These interventions also include the removal of dental calculus and tooth polishing, which is done in the aim of preventing or treating periodontitis and caries.


Fissures are the grooves or cracks in the top surface of back teeth. These fissures are often so deep that food gets stuck inside, causing conditions for the development of bacteria and caries. The fissure sealing procedure implies coating the fissures with a mass similar to liquid composite in order to fill the grooves and reduce their depth, thus preventing food retention and tooth decay.

This intervention takes about 10 minutes per tooth. The tooth isn’t processed by a drill, so it is completely painless and comfortable for the child. After tooth polishing, this is the ideal intervention for children to become acquainted with their dentist.


Fluoride treatment of teeth is a procedure in which fluoride molecules are incorporated into tooth enamel to improve and speed up re-mineralization and prevent tooth decay. It is conducted by applying special gels with a high concentration of fluoride for 5 to 15 minutes in the dental office.


Tooth calculus is the main supporting factor in periodontitis. Its rough edges contribute to gum damage, resulting in bleeding gums during teeth brushing. Its microscopic structure in the form of holes is the ideal place for bacteria buildup and microscopic food remains that cannot be reached by toothbrush bristles, preventing adequate oral hygiene.

Calculus can be found below the gums and it isn’t visible by the naked eye, it can only be discovered by the dentist during a checkup. This subgingival calculus (below the gum line) is the most dangerous and leads to periodontitis.

The removal of tooth calculus falls under both prevention and treatment in periodontics therapy. In the preventive sense, at least two therapies a year are recommended, unless specified differently by the dentist.
