I don't understand what the oil would be absorbing. An infection it can't help, bacteria it wouldn't pull or absorb.
Reverse osmosis water though could be sufficiently pure where when drak it 'pulled' bacteria, debris more. In fact I've used to water to pickle fresh pot before drying for a 20+% more potent weed; it's called 'hungry water' sometimes because it's so pure things passively transport into it greatly
It's a recent thing I've been doing, from what I've read coconut oil has antimicrobial properties, moisturizes the gums and aids in saliva production which helps to keep the bacteria down. I'm going on 40 and have only ever gone to the dentist for routine cleanings. I do dip and am always on a lookout for ways to nlminimize the damage from that. I imagine at some point a good diet and genetics probably play a significant role in having a healthy mouth.
for your dipping, coconut oil i could see work as a salve. if you are not going to quit you should at least resolve to cut the abrasives out of the dipping product if not already.
