Cleaning done right: Why 90% of people make a mistake
Almost everyone thinks they brush their teeth correctly – but studies show that around 90% make at least one crucial mistake. The result: plaque sticks, gums become inflamed, and long-term problems like periodontitis can develop. In this article, you'll learn what you really need to pay attention to in order to optimally protect your oral health.
What is the problem?
Brushing your teeth sounds simple: toothbrush, toothpaste, and off you go. But many people scrub too hard, use the wrong technique, or rinse everything out immediately after brushing. All of this reduces the effectiveness of brushing – and can even cause damage, such as receding gums or sensitive tooth necks.
Why is it important?
Your teeth are exposed daily to attacks from bacteria, sugar, and acids. If you brush incorrectly, you won't remove biofilm (plaque) thoroughly or you'll unnecessarily stress your gums. In the long run, this can lead to cavities and periodontitis – diseases that affect not only your teeth but also your overall health (e.g., increasing your risk of cardiovascular disease).
Science explained briefly
Research shows that biofilm – a thin layer of bacteria – reforms within hours. If it isn't properly removed, deposits harden into tartar. At the same time, studies demonstrate that rinsing immediately after brushing removes the protective film of fluoride and other active ingredients before they can take effect. Therefore, dentists advise: Spit, but don't rinse.
What can you do?
- Use a gentle technique – small, circular movements instead of hard scrubbing.
- Choose the right brush – soft bristles are better for teeth and gums.
- Do not rinse immediately – this will keep the active ingredients in your toothpaste (e.g. fluoride or the PerioTrap® technology) active for longer.
- Brush twice a day for 2 minutes – and clean between your teeth at least once a day.
In summary
- Most people rinse incorrectly after cleaning.
- Incorrect brushing damages gums and teeth.
- Gentle cleaning and letting the active ingredients work provides better protection.
Did you know?
Most people only brush their teeth for an average of 45 seconds – but at least 2 minutes are recommended to ensure that all tooth surfaces are reached!
