The effect on the gums is immediately noticeable through their astringent effect. The gums are tightened and strengthened. The bacterial plaque is removed and the formation of new plaque is reduced. Tooth enamel hardens with the aluminum fluoride used and is therefore more resistant to caries. The result: Bleeding gums stops. The sensitivity of the teeth to irritation and pain is reduced. Gum disease is prevented to protect and maintain healthy teeth.
