Perio support Pro is designed to be used between veterinary dental cleanings to penetrate plaque and support gum health, which helps maintain clean teeth and fresh breath. Perio support Pro includes natural zeolites and unique minerals that help prevent plaque formation. It also contains beneficial, direct-fed microbial, lactobacillus acidophilus, and enterococcus faecium, which help restore microbial balance in the mouth and displace unhealthy, plaque-causing bacteria.
