I guess I meant "thick". It seems some of the thicker oils have major cleaning actions, such as hemp, etc. Funny though, I would consider Olive-Oil
thick, but it tends to discolor some people's teeth....I have personally never used it, and it is the oil of choice for some people.
I've had great luck with thick oils on my teeth whitening. For me personally, coconut oil cleans my teeth like no one's business. But so does the Udo's Oil. Sunflower just doesn't do if for me anymore.
I still maintain that everyone is individual, and what works for some does not work for others. That being said, I'd start to experiment a bit. There is an oil out there that will be perfect for you.
