It's not possible to go to such low level because it's a job of embedded controller in SSD and it's firmware that is instantly remapping bad flash sectors and hiding it from user (using ECC and wear leveling algorithms). When flash cells wear out and there are no left spare to remap data loss may suddenly happen. Or at least SSD switch to read-only mode in a better case. There is SMART attribute Total LBA written that may indicate you how many TB of data was written and compare it to typical SSD life. There may be also some other vendor specific SMART attributes that can tell better but it's not standardized, sigh...
