The dental bonus booklet for higher contributions towards the costs of necessary dental prostheses is available from your dentist. To take part in the TK Bonus Plan you no longer need a special TK bonus booklet; instead, you can just enter the check-up online.
More details
If your dentist no longer has any dental bonus booklets in stock, he can order more from the Kassenzahnärztliche Vereinigung [National Association of Statutory Health Insurance Dentists].
If you have lost your bonus booklet, your dentist can issue a new one based on the data in your patient file.
