I am a regular user and an avid proponent of Dabur Red toothpaste. In my experience it is pretty effective as a toothpaste and as a preventive for mild oral ailments. Application of Dabur toothpaste in situ also alleviates mild gum pain. Mind you I have no scientific evidence collated, this is all through experience from actual usage.
With the Patanjali products wave, I decided to give Dant Kanti a fair go.
I found it a bit too sweet for my palate. I used one large tube but to be honest I constantly felt that Dabur Red was and is better for me.
I have therefore reverted to Dabur Red. No more Dant Kanti, thank you. Though I must fairly concede that several of Patanjali products are really good. And VFM.
