Despite the advertising messages insistently underline its usefulness in the prevention of plaque, and in the treatment of particular conditions of the oral cavity, such as gingivitis, canker sores and bad breath, the mouthwash therefore remains a purely auxiliary tool. The use of mouthwash alone is not in fact, it is sufficient to obtain "adequate oral hygiene, nor to make one's teeth whiter. Indeed, if we take the example of chlorhexidine-based mouthwashes - types of mouthwash recommended in the presence of chronic gingivitis, very aggressive carious diseases or important problems of the periodontium - we find that these are very often associated with the presence of brown spots on the teeth and tongue. However, these are superficial stains, which can be easily removed during outpatient hygiene. The same goes for mouthwashes based on amino fluoride and stannous fluoride.
What does it contain
Common ingredients of the various mouthwashes are obviously water and acaryogenic sweeteners, such as xylitol (which also has a mild antibacterial activity), sorbitol, sucralose and sodium saccharin. Sometimes, especially in commercial mouthwashes, we also find a significant amount of alcohol, used above all to enhance the flavor of the product rather than for the real antibacterial properties, particularly contained at the concentrations used. Alcohol can, on the other hand, have an irritating effect on the oral mucosa.
Mouthwash: Main categories
Generally speaking, mouthwashes can be divided into two categories: medicated mouthwashes (sold only in pharmacies) and cosmetic mouthwashes (sold freely). The former contain chemical substances with a powerful antibacterial action (mainly chlorhexidine), while in the latter the presence of fluorine is predominant, which due to its ability to promote the repair of micro-lesions of the enamel, is considered an effective agent against caries.
very effective, because it can destroy all the bacteria present in the oral cavity with a prolonged effect. Not surprisingly, it is considered the chemical disinfectant - anti-plaque agent par excellence. The antibacterial power of chlorhexidine, however, is accompanied by important side effects, which require a careful use of mouthwash: no more than twice a day for periods of two three weeks, and only on the prescription of the dentist.Inappropriate use creates bacterial resistance and inflammation of the mucous membranes; as mentioned, it tends to stain the teeth and, if used for long periods to replace the toothbrush and dental floss, it is ineffective or even harmful, above all because it subverts the ecological balance of the oral bacterial flora.
PLEASE NOTE: chlorhexidine has as a side effect the phenomenon of the pigmentation of tartar and bacterial plaque adhering to the surface of the teeth.

Even essential oils have an excellent bactericidal power, however limited if we consider the concentrations that can be used in common mouthwashes. Essential oils are often added for their antialitosic, refreshing, slightly anesthetic and consumer recall action. A universally used ingredient is peppermint essential oil, together with menthol and thymol. Other essential oils commonly found in mouthwashes are those of sage, lemon, anise, cinnamon, carnation and myrrh.
Hexetidine-based mouthwashes
Hexetidine is a local anesthetic, astringent, anti-plaque and deodorant agent; used to treat pharyngitis (sore throat), laryngitis, gingivitis, ulcerative stomatitis and tonsillitis.
Mouthwashes with fluoride and derivatives, such as amine fluoride and stannous fluoride
More than for their mild antibacterial properties, they are mainly used to remineralize teeth and prevent tooth decay and excessive tooth sensitivity. If used in excess, however, these mouthwashes can cause fluorosis, with a paradoxical demineralizing and erosive effect.
Commercial mouthwashes
Regardless of the ingredients, as a rule, in the presence of an oral cavity disorder it is very important to bring it to the attention of a dentist to identify the causes and possibly choose the most suitable mouthwash for your needs.
