My boy is 16 now, so when his breath got really bad and his teeth started looking worse, I honestly thought there wasn’t much I could do at his age. Brushing him is basically impossible. I started adding one scoop of this to his food every day and we've been using it for just over 6 months now. His breath is SO much better, his mouth looks cleaner, and even his gums look healthier than they did before. At 16, I'm not expecting miracles. I just want to keep him comfortable and take care of the years we still have together. This has become one of those things I wouldn't stop giving him.
