On that note I've always wondered if putting an SSD in an oven at the highest temperature just before damaging it could revive it from being written to and erased too many times.

The same mechanism that makes SSD's not retain data (that is, the electrons escaping) and the same thing which makes them not retain the data that you do want to keep would presumably also make the electron buildup that you get that kills the cells abilities to continue their write/erase cycle.
