If you want to whiten your teeth, you can choose from a wide range of options today, which differ among other things in their intensity of teeth whitening and the possible side effects. There are special products for home use and treatments that the dentist performs.

Get white teeth at home

Brushing your teeth regularly and thoroughly – this is the most important prerequisite for beautiful, white teeth!

  • Brush your teeth at least twice a day
  • Pay attention to the correct tooth brushing technique
  • Also clean the interdental spaces thoroughly (with special brushes and / or dental floss)
  • Replace the toothbrush every three months at the latest, as worn or bent bristles no longer guarantee perfect cleaning performance

Extra tip: If you want to do even more for white teeth, you can use whitening toothpaste.

Special toothpastes for white teeth have been developed to bring out the natural whiteness of the teeth.

Corresponding whitening toothpastes usually contain special cleaning agents ("emery materials") that can dissolve surface stains. The products offered differ, among other things, with regard to the intensity of the abrasive (abrasive) effect and their additional effects (e.g. gum protection).

If you want to bleach your teeth yourself, you can use various over-the-counter tooth bleaching agents with hydrogen peroxide or other bleaching ingredients (e.g. whitening strips, tooth-white pencil or similar).

However, experts advise against such bleaching agents for teeth. Improper use can, among other things, irritate the gums or even damage the teeth (e.g. if the bleach spills out of a splint). Accordingly, it was also legally stipulated that corresponding teeth whitening products for personal use must not exceed a concentration of 0.1% hydrogen peroxide. * A real brightening effect is questionable anyway.

There are many home remedies for white teeth. Especially baking soda for white teeth is a real long-time favorite among the secret recipes.

Experts advise caution: even if the teeth can actually appear whiter for a short time, the substances usually also attack the enamel. This allows color particles to adhere more easily to the tooth – it darkens. Last but not least, the enamel degradation that is favored in this way ensures that the yellowish dentine shines through. White teeth? None!

Whiten teeth at the dentist

Professional tooth cleaning is recommended to bring out the natural whiteness of the teeth. After all, deposits and tartar are removed from the teeth particularly thoroughly and also polished. At the same time, regular professional tooth cleaning also prevents dental problems such as tooth decay or gingivitis.

Whitening is the bleaching of teeth with chemical substances (especially hydrogen peroxide). In order to prevent damage to teeth and gums as well as irregular results, it is strongly advised to carry out bleaching only under the supervision of a dentist and not to use over-the-counter bleaching products.

Different approaches are possible:

  • Home bleaching: The dentist creates an individual plastic splint that the user fills with bleaching gel at home and wears for hours. The duration of the treatment is approximately 2 weeks
  • Office bleaching: Teeth bleaching in the dentist’s office with a correspondingly higher dose of bleach
  • Power Bleaching: Accelerate office bleaching using UV light or laser

The result of whitening usually lasts up to three years.

Brush your teeth thoroughly and regularly

Naturally white teeth? Those who pay attention to thorough and regular dental care create the best basis. Brush your teeth twice a day and also pay attention to cleaning the interdental spaces (e.g. with special interdental brushes and dental floss). Replace your toothbrush at least every three months so as not to reduce the cleaning result from worn bristles.

Caution with over-the-counter tooth bleaching agents

Teeth whitening at home? That sounds comfortable, but over-the-counter tooth bleaching agents such as whitening strips or whitening pencils are judged extremely critically by experts. For example, improperly used bleaching agents can cause gum irritation. Accordingly, the highest concentration of bleaching agent has been set by law (0.1% hydrogen peroxide) – the bleaching effect can therefore be assessed as low.

Important: It is strongly advised against bleaching agents with a higher concentration (e.g. via online mail order).
