The article from Iltalehti emphasizes the dental health risks associated with using individual toothbrush mugs for children. Research indicates that children who utilize such cups tend to have higher instances of cavities and dental issues compared to those who do not use them. The concern is that when children rinse their mouths with large amounts of water after brushing, they inadvertently wash away fluoride from their toothpaste, which is crucial for preventing tooth decay.

In addition to the risk of increased cavities, the article references guidelines from the 'Käypä hoito' site, which suggest that the practice of rinsing with a toothbrush mug may be particularly detrimental. Children who use these mugs during tooth brushing have shown less protection against decay due to their rinsing methods. Alternatively, it is advised that children should rinse their mouths with a minimal amount of water and do so gently to retain the beneficial effects of fluoride on their teeth.

Ultimately, the article encourages parents to reconsider the use of toothbrush mugs in order to promote better oral hygiene practices and enhance the protective effects of fluoride toothpaste. By making small changes, such as limiting rinsing after brushing, parents can support healthier dental outcomes for their children.
