yes all 4 at once, with 1 upper and 1 lower molar with them, for a grand total of 6.
they were huge from the x-ray, but i didnt se em cause i was drugged out and they said i wasnt allowed to get them back, fricking military.

didnt feel nothing, but i felt lighter and there was a huge gap in the back of my mouth that there was no ignoring.
its good tho, they really dont do nothing except grow and take up space
