Teeth whitening in Germany: dentist treatments, home options and insurance

• In the dental practice (in-office or chairside bleaching): the dentist protects the gums and applies the whitening gel; the process may be repeated depending on the starting shade.
• Dentist-supervised home bleaching: the practice makes custom-fitted trays; after instruction you apply the gel yourself at home over a period agreed with the dentist.
• Over-the-counter products: they contain less active ingredient than practice products. According to the BZÄK, the results are usually only moderately satisfying, and they can still damage teeth and gums.

For teeth that are discoloured from the inside, for example after root canal treatment, there is a separate in-practice method (internal bleaching, "walking bleach"). This guide deliberately contains no instructions, concentrations or application times — these belong in the hands of the dental practice.

According to the BZÄK, whitening is possible on healthy, vital teeth with healthy gums. With decay or leaking crowns and fillings, the bleaching agent can penetrate into the tooth and damage the nerve. A dental check for decay and cracks before any use is therefore essential — also if you plan to use products at home.

The most common side effect is temporary sensitivity to heat, cold or touch. With very sensitive teeth, bleaching should be considered carefully. The BZÄK advises pregnant and breastfeeding women against whitening because there is not enough scientific knowledge, and advises against it with known allergies to ingredients. If severe pain occurs, the treatment must be stopped immediately. Whether a method suits you can only be judged individually.

Fillings, crowns, bridges and veneers do not lighten. After whitening, they may stand out and may later need to be adapted to the new tooth colour by the dentist or dental laboratory — which can cause additional costs. Root-canal-treated teeth are not lightened from the outside either. Clarify this before treatment if you have visible restorations.

A professional teeth cleaning removes plaque, tartar and surface discolouration and restores the natural shade; it does not change the colour of the tooth itself. Bleaching lightens the tooth colour chemically. The BZÄK recommends a professional cleaning before any bleaching so that the gel can act evenly. Whitening toothpastes mainly remove external discolouration through a higher content of abrasive particles.

How long the result lasts varies: according to the BZÄK, from several months to up to two years. Smoking and colouring foods and drinks such as coffee, tea or red wine shorten the effect.

We do not quote prices here because we found no reliable current source for Germany. Cost factors include the method, the number of sessions, a professional cleaning beforehand, custom trays for home bleaching and any later adjustment of fillings or crowns. Ask your practice for a written cost estimate.

• Statutory health insurance (GKV): bleaching is not listed in the overview of statutory dental benefits on gesund.bund.de. Ask your health insurer if in doubt.
• Supplementary dental insurance: many tariffs do not include bleaching. Example (provider information): in the DFV ZahnSchutz Exklusiv 100 tariff (version 01.08.2025), whitening by a dentist is reimbursed once every three calendar years, within a combined maximum of €200 per calendar year shared with prophylaxis such as professional teeth cleaning. Other tariffs differ or exclude it.

Do not assume that bleaching is insured. Check the conditions of your specific tariff before treatment.
