The 10 biggest dental care myths


To keep our teeth healthy, they should be thoroughly cleaned with toothbrush and toothpaste at least twice a day. Also, the daily use of dental floss is recommended to remove food particles from the interdental spaces. In addition to toothbrush & Co., there are many more tips for healthy teeth. But beware: not everything that is said about the dental care, is actually true. We clean up with the 10 biggest dental care myths.

1) Scrub hard brings the most

Not correct! Although it is important to thoroughly clean the teeth, solid scrubbing is not necessary. For who pushes too hard with the toothbrush, strained teeth and gums. The pressure can cause the gums to retract, resulting in exposed tooth necks. In addition, the protective enamel can be damaged. Therefore, when brushing, be sure to apply only light pressure.

2) Bad teeth are hereditary

Not correct! Bad teeth are not hereditary - just because the parents had bad teeth does not mean that you also have problems with your teeth. Some factors are genetically determined, such as the thickness of the enamel or the tooth position. In general, however, a clean tooth will not get caries - and you'll be completely responsible for keeping your teeth clean.

3) Black tea damages the teeth

Not correct! Although some teas - including black tea - cause the teeth to discolour - these discolorations can be polished away without any problems. The enamel does not harm black tea, only some very sour fruit teas can cause damage with frequent consumption. In contrast, black tea can even have a positive effect on the teeth because it contains fluoride that is supposed to harden the enamel.

4) Chewing gum substitutes brushing teeth

Not correct! Chewing gum does not replace the care of teeth with toothbrush and floss. Rather, chewing should be considered as an extra care measure - provided that it is sugar-free chewing gum.

Especially recommended are special Zahnpflegekaugummis with xylitol or similar substances. The chewing gum stimulates saliva production, which neutralizes harmful acids and hardens the enamel. In order to remove the plaque on the teeth, careful brushing of the teeth is absolutely necessary.

5) Eating apples prevents tooth decay

Not correct! The rumor that the consumption of foods with a hard consistency such as apples or carrots can prevent the development of tooth decay persists. In fact, such foods cause the upper deposits on the teeth to be rubbed off. In order to remove also the stuck plaque and to clean the interdental spaces, toothbrush and dental floss are indispensable.

However, there's nothing wrong with snacking on an apple or carrot in between. With apples, however, you should note that these are rich in fructose and the acid contained can attack the enamel.

6) Milk teeth do not need to be cared for

Not correct! The opinion that milk teeth may have quiet tooth decay, as they will fail again, is widespread. However, the milk teeth must be cared for carefully. Because tooth decay on the deciduous teeth, the tooth crown of the permanent teeth can be damaged.

If tooth decay leads to premature loss of the deciduous tooth, the permanent tooth may also break through the gum in a bad position, which may later necessitate orthodontic corrections.

7) Brushing your teeth right after eating is important

Not correct! Although you should brush your teeth best after your meal, but not immediately afterwards. This is especially true if you have eaten fruit for dessert. Because the acidity of fruits and fruit juices makes the enamel soft and can be attacked when brushing your teeth.

Besides fruits, drinks such as wine or cola can soften the enamel. Therefore wait at least 30 minutes after your meal to brush your teeth. That's how long it takes for the saliva to neutralize the acid in the mouth.

8) All whitening toothpastes are harmful

Not correct! When whitening toothpastes, it always depends on the product. Many of the pastes contain aggressive emery substances that can attack the enamel and thereby damage the tooth. You should keep your hands off such products. However, some creams are also relatively mild and contain only a few abrasive substances. If in doubt, ask your dentist if the paste is dangerous to your teeth.

Alternatively, if you want whiter teeth, you may want to think about whitening your teeth. But again, you should consult with your dentist.

9) One minute brushing is enough

Not correct! Instead of one minute, you should spend at least three minutes in your morning and evening dental care. That's how long it takes, for example, to remove all plaque from the tooth surfaces while brushing. In addition, the substances contained in the toothpaste, such as fluoride, have to act on the teeth for a certain time. In the evenings, it is important to take time to brush your teeth since teeth can regenerate best overnight.

10) Smoking only discolors the teeth superficially

Not correct! Anyone who smokes regularly has to expect that their teeth will turn yellowish over time. Superficial discolorations can be polished away, but deeper discolorations remain.

In addition, the supply of the gums with blood and oxygen also deteriorates due to smoking. This can lead to painful gingivitis and in the worst case even to periodontitis and tooth loss.
