So far so good
Have been using for a little over a month. Can't say whether it is making a difference with her teeth health as she is young and we wanted to start early as preventative. Breath smells similar to previous. But I CAN say that she absolutely LOVES the taste and I only have to mention "you want your chewie?" (she knows that means the Bright chew) and she sprints to the cupboard and waits excitedly for me to put on the toothpaste. So I figure no harm done, we'll continue and see if it helps keep her teeth clean long-term because she clearly loves the chewie anyway :)
