I couldnt find any specific information about the Oral-B Oralon mouthwash. However, I can provide general information about mouthwashes and their ingredients from the search results.

Mouthwashes can be broadly classified into two types: cosmetic and therapeutic. Cosmetic mouthwashes may temporarily control bad breath and leave behind a pleasant taste, but have no chemical or biological application beyond their temporary benefit. On the other hand, therapeutic mouthwashes have active ingredients intended to help control or reduce conditions like bad breath, gingivitis, plaque, and tooth decay.

Active ingredients that may be used in therapeutic mouthwash include cetylpyridinium chloride, chlorhexidine, essential oils, fluoride, and peroxide. Antimicrobials in mouthwash formulations include chlorhexidine, chlorine dioxide, cetylpyridinium chloride, and essential oils (e.g., eucalyptol, menthol, thymol, and methyl salicylate) .

Chlorhexidine mouthwash is used to treat gum disease because of its anti-inflammatory effect. It inhibits plaque buildup and is particularly recommended for gingivitis. Other active ingredients like fluoride can help prevent tooth decay.

It is important to note that some dentifrice ingredients (like calcium hydroxide or aluminum hydroxide) can form a complex with fluoride ions and reduce a mouthwashs effectiveness. Therefore, vigorous rinsing with water may be recommended after brushing and before rinsing if these ingredients are present.

Overall, the effectiveness of a mouthwash depends on its active ingredients and their concentrations. Dentists can choose the most suitable one for each clinical situation and guide patients correctly.
