I am using HealthMouth which has obtained the VOHC seal. The company's clinical trials were headed by Dr Jean Dodds. I don't think any of these products take the place of a dental cleaning under anesthesia - I brush daily and feed grain free home cooked organic food and my 3.5 year old yorkie had 7 teeth extracted due to dental disease that was identified via X-rays. Leba has only anecdotal evidence to support its claims and no science behind it. Here is a product comparison in case you are like me and want science not marketing to guide your product choice. Plus if you like holistic approaches, dr Dodds is like the holistic guru and even won holistic vet of the year at one time.
