toothpaste

Just wondering what products anyone has used for gingivitis that seems to have worked. Interested to hear from those particularly who have had success using products for kitten gingivitis. Used dentipet vet recommended but no good currently using hartz and looking for other options. Thanks!

Simba's teeth are a bit discolored in the front. He needs a dental cleaning, which I'm arranging. How do you guys keep their teeth clean? Brushing his teeth is an act of congress and I don't think I'm doing it right. I have been reading about water addictives and so many are unsafe to swallow...
