A bright smile and healthy teeth: what can mouthwashes really do?

Toothbrush, toothpaste and dental floss – an effective triad for good dental health. Do you really need a mouthwash? Stiftung Warentest has the answer.

Grandpa’s mouthwash is experiencing a renaissance as a mouthwash: But today’s mouthwashes can do much more than conjure up fresh breath. Gargling daily as part of dental hygiene has been shown to prevent tooth decay, bleeding gums and periodontal disease. Stiftung Warentest shows that mouthwash and mouth rinse are not the same and names the test winners for oral hygiene.

The best oral hygiene: mouthwash or mouthwash?

In the Stiftung Warentest, 13 ready-to-use mouthwashes and seven diluted mouthwashes compete against each other. It quickly becomes clear what the differences are: Mouthwashes are taken undiluted in the mouth and mouthwashes are diluted with a little water. In addition, many mouthwashes contain fluoride to protect against tooth decay, mouthwashes do not. If you are looking for caries protection, you should therefore prefer to use a mouthwash.

Both remedies could help against gum inflammation and plaque. Unfortunately, only the mouthwashes contained enough of the necessary active ingredients in the test. This means that the mouthwashes fall through to dilute in the rest of the goods foundation and are ideally suited as a freshness kick for the breath.

The fight against tooth decay, plaque and gingivitis

Strong against tooth decay: To prevent tooth decay, the mouthwash must contain sufficient fluoride – from 0.025 percent fluoride, an improvement can be proven, according to the National Association of Statutory Health Insurance Physicians (KZBV). This additive returns minerals to the tooth surface and makes it more resistant to acids.

Protection against gingivitis:

Deposits on teeth caused by plaque bacteria can lead to inflamed gums.

This not only creates terrible toothache, but in the worst case scenario can also lead to receding gums and wobbling teeth. Some mouthwashes can fight the bacteria through various ingredients: amine fluoride and zinc salts, certain essential oils and cetylpyridinium chloride are used.

Who should use a mouthwash?

Mouth rinses can be used to support dental care – but they cannot replace daily brushing. With these tips, brushing your teeth is guaranteed. Dentists recommend additional cleaning with a mouthwash especially in the following cases:

  • teeth prone to tooth decay or gingivitis
  • with exposed tooth necks
  • for periodontal treatment
  • for fixed braces with so-called brackets
  • Brushing your teeth or flossing is difficult
  • You can only brush your teeth to a limited extent after an operation

Can mouthwashes protect against corona viruses?

In some cases, mouth rinsing solutions that contain essential oils or cetylpyridinium chloride can significantly reduce corona viruses. However, the experiments with artificial saliva took place in the laboratory. How far the results can be transferred to everyday life and how long the virus-inhibiting effect will last cannot be clearly stated at the moment. We have summarized the research results on mouthwashes as corona killers for you.

The test winners: good mouthwashes don’t have to be expensive!

According to Stiftung Warentest, eight of the 13 ready-to-use mouthwashes reliably prevent tooth decay, gingivitis and dental plaque. Amazing: The cheapest solutions occupy the top three places. The own brands of Edeka, Kaufland and Lidl can score points with 72 cents per solution. On the other hand, you can save the money for mouthwash concentrates to dilute.
