Opalescence PfPosted on April 10, 2010. How many times can I whiten my teeth with Opalescence? I had a course of treatment in December, applied the treatment 8 times, about 8-10 hours .. PF20 I used. When can I use it next time? and perhaps I FP 40? 2 times per day CommentsThere are no comments.Leave a Comment | Popular My Friends |
