Stiftung Warentest - Some mouthwashes are poor

The price is not a reliable indicator of a good product

Many people use mouthwashes to supplement their daily dental care. The promises on the respective products are often similar. This does not always correspond to reality. The Stiftung Warentest recently tested 20 mouthwash solutions - with an astonishing result. In addition to positive examples, bogus packs were also in the test repertoire. The respective price of the conditioner was not a reliable factor for a good product.

According to Stiftung Warentest, twelve of the products tested can be relied on. They prevent gingivitis, plaque and tooth decay. The good thing about the best products in each case is that they also belong to the comparatively cheaper mouthwashes. On the other hand, three expensive branded products have been given a "poor" rating because they do not provide adequate protection against plaque and gingivitis or fail to protect against caries, although this is advertised on the package.

Not all mouthwashes are recommended

The majority of the twenty tested products did well in the test. However, the Stiftung Warentest penalized five products as not recommended. It is particularly surprising that three of the defective products are expensive branded articles from Biorepair, Karex and Zendium. It is also surprising that the only mouthwash with the grade "very good" comes from the discounter and is only one of the cheapest products in the test at just 0.15 euros per 100 milliliters. The private label Dontodent of the drugstore dm is therefore at the top of the podium. But the victory at dm can only be celebrated to a limited extent, because the in-house children's mouthwash Dontodent Junior with a berry taste received the grade "Poor".

There is no scientific evidence for the use of hydroxyapatite

The positive effect of fluoride on teeth has been scientifically proven. It serves as tooth decay prevention, mineralises the tooth surface and makes it more resistant to acids. Two of the products tested by Stiftung Warentest use hydroxyapatite instead of fluoride. According to the providers of the products, the fabric combines with the tooth surface and thus imitates the tooth enamel. However, the providers were unable to provide any scientific evidence that hydroxylapatite works as effectively as fluoride.

Cheated while filling

A particularly brazen case was one of the most expensive products in the test. The buyers of the mouthwash are asked to pay around five euros, but instead of the declared 400 milliliters, they only receive around 350. Another mock pack was the only natural cosmetic product in the test.

Parental controls are missing in most products

Stiftung Warentest recommends that children only use mouthwashes containing fluoride if they can spit them out reliably. That was the case at around six years old. The colorful waters with the unusual smell arouse curiosity, especially in children. Therefore, Stiftung Warentest gave point deductions for insufficient child protection, which was the case for 17 of the 20 products. According to Stiftung Warentest, most solutions do not contain alcohol, but they should not be swallowed.

Who benefits from mouthwashes?

For people who find it difficult to clean the narrow interdental spaces, mouthwash solutions can be a useful addition to oral hygiene. Dentists explain to Stiftung Warentest that especially young people with fixed braces or older people who can no longer clean their teeth manually can benefit from mouthwashes. The mouthwash solutions are also suitable for people with frequent caries problems. The detailed test can be purchased on the Stiftung Warentest website. (fp)
