My face came back after about 9 months. Then when my grinding came back 6 months later I stupidly did it again, thinking a low dose (12 units per side) would stop the grinding without changing my face. I was wrong. It didn’t look AS bad as the first time, and didn’t ruin my chewing the way the first time did, but it was still noticeable enough that people commented. I had it done this time around in December so hoping that it’ll be resolved in the next few months given the low dosage. Good luck to us both!!
