    * Chlorhexidine: Its most common formulation is as digluconato chlorhexidine, in an aqueous solution or an alcoholic, and is presented in mouthwashes, gels, toothpaste, sprays and varnishes. There is some experience with chlorhexidine added to chewing gum, in which there are chlorhexidine acetate at a concentration of 0.625% in combination with xylitol to 34%, in these experiments is verified the effectiveness of antibacterial gum.

     * Oil phenolic: As the Listerine.
     * Xylitol.
     * Oxidizing agents: As the hydrogen peroxide, car amide peroxide or urea peroxide, peroxide and sodium bicarbonate monosulfato (the latter very useful, because it is more gentle and harmless to others, and quite effective).
