Fluorisation is the procedure which protects teeth from caries. In practice, it consists in covering the teeth with a fluorine compound in the form of a solution, gel, or varnish applied with a brush or rubbed onto the teeth. Fluorisation should be preceded by a comprehensive tooth bleaching procedure which enables professional cleaning of the denture by scaling and sandblasting followed by whitening proper. The procedure can also come as the last stage in the cosmetic treatment. The therapy is aimed at strengthening the enamel and increasing its resistance to caries, the latter being of utter significance in maintaining health, especially in children.
Released gradually and slowly, fluorine builds into the tooth enamel and acts on the calcium compounds in its body thanks to which they are less readily soluble in acids and become more resistant to caries. The tooth structure reinforces as fluorine is released, and this makes the teeth more resistant to the impact of the acids contained in the plaque. Moreover, fluorine compounds themselves restrict bacterial growth triggering remineralisation of minute enamel chip-offs.
The preparations we use are characterised by high concentration of fluorine. This makes them bind quickly and adhere to the tooth surface well. From there, they steadily release small quantities of fluorine. These attributes of the preparations, combined with their application under medical direction ensure highest safety of the fluorisation procedure. Indeed, if overdosed or applied incorrectly, the preparations could inflict a serious damage. Fluorisation carried out in clinical conditions has a definite advantage over any such treatment applied at home where we use flourine-based toothpastes in that it is incomparably more effective. The applied varnish containing fluorine compounds acts on the enamel for an odd dozen hours, slowly releasing highly concentrated fluorine. Brushing the teeth, on the other hand, we give fluorine but a brief moment to act. Even though, the latter should complement the treatment.
Fluorine varnish for adults is colourless, and this it is imperceptible after the procedure. The type used in children is the colour of honey so as to monitor the quantity of the applied preparation. Tooth varnishing in children should be repeated four times a year, whereas in adults twice a year.
Fluorine tooth varnishing is frequently mistaken for sealing. Tooth sealing is a preventive procedure which consists in filling in the fissures of the molars and premolars with a special substance called dental sealant.
