Possible saturation of betatron acceleration of dust particles behind strongshock fronts from supernovae is considered. It is argued that the efficiency ofthe nonthermal dust destruction should be substantially lower than the valueestimated from a traditional description of betatron acceleration of dustgrains behind radiative shock waves. The inhibition of the nonthermaldestruction can be connected with the mirror instability developed in the dustcomponent behind strong shocks with the velocity 3 times exceeding the Alfv\'enspeed. The instability develops on characteristic time scales much shorter theage of a supernova remnant, thus its influence on the efficiency of dustdestruction can be substantial: in the range of shock velocities 100 kms$^{-1}<v_s<300$ km s$^{-1}$ the destruction efficiency can be an order ofmagnitude lower that normally estimated.
