How important is the number of the tooth treated on the invoice?

It is very important that the claims handler can follow the indemnity rules established in the terms and conditions of the insurance contract (eg 1 filling per tooth). If the invoice that you submit to the Insurer does not have a tooth number (or a tooth formula), the claims handler will ask you to submit a medical card (Ravikaart) with a tooth number. The dentist can also write the tooth number on the invoice by hand.
