1. A method for excavating dental material (107) comprising:
arranging (S101) a structure-borne sound sensor (109) on a tooth (103);
excavating (S102) the tooth material (107) comprising carious tooth material with a fluid jet (111);
detecting (S103) structure-borne sound signals (121) of the tooth (103), generated by the fluid jet (111) during the excavation, by the structure-borne sound sensor (109); and
regulating or controlling (S104) a fluid jet generator (101), which controls the fluid jet, based on the structure-borne sound signals (121);
wherein a type of tooth material is detected based on the structure-borne sound signals;
wherein the type of tooth material (107) is detected based on a slope of a cumulative energy of bursts (115) and the frequency of the bursts or the number of bursts per unit of time.
