How do i get my dog to stop chewing on stuff she isn't supposed to?

All in the title! Today after coming back from the library I saw that my dog chewed on almost everything in the house (electronics*, medicine**, mail, books, Swiffer stuff, the works) but her like 20 - 15 toys, so can anyone here tell me how to train her to not do that, or does she have to stay in her kennel when we aren't watching her for sleep/trips/whatever? Any help is appreciated!

*Not plugged in, but was completely destroyed (motherboard expoosed, cord severed and buttons torn)

**She didn't breach the packaging, thank god, but attempted to chew on the tablets inside.
