When do you guys slow down betting with an over pair?

Example. You are dealt TT, JJ, QQ and you raise pre flop and get 1 caller.

Flop comes all low cards. You bet the pot and get called. Turn is another low card. Do you you make another pot bet or slow it down? Same for river?

Been getting killed with over aggressive play with over pairs. Been getting called all the way to showdown only to find the villan have a set or a higher pair like KK or AA.
