摘要：
The invention relates to oral and dental hygiene and cleaning agents which contain, in relation to their weight, between 0.001 and 25% by weight polylactic acid particles and between 1 and 30% by weight precipitated silicic acid(s) with a specific surface area according to ISO 5794-1, Appendix D, of ≦60 m2/g. said agents exhibit a reduced damaging action in comparison to pure silicate-based compositions. In particular, the sensitivity of the teeth during and after the cleaning process is reduced.
