I used some coconut oil today on my head for my psoriasis, and remembered that it's also helpful for dental issues. Here's how to oil pull.
Why Pull?
There are several different oils that can be used for this method. I prefer coconut oil, which is like the second-from-the-top but it tastes much better. The idea is to swish it between your teeth, working from left to right and back again, ensuring that the oil goes between each of your teeth on the upper and lower rows.
This will help keep your teeth clean.
How?
I generally take a spoonful of the oil, and put it in my mouth. I "chew" it to make it more liquid, and swallow some of it (only at the beginning! You don't want to swallow any of it once it has "pulled" the bacteria and other bad stuff from your teeth!), and then start swishing it between my teeth as mentioned above.
Generally, I do this in the morning while I'm sitting on the toilet and reading -- thus, it's not taking any additional time out of my day. You want to do this for 15-20 minutes at a time, but when you get started it'll likely provoke a gag reflex so you'll also want to be near a sink or waste basket. After a couple times I was able to continue to the end without gagging. Note though that I do tend to swallow a little, as one's throat wants to continue to be coated while one is breathing...
Once you're done, you will want to spit it out completely. The way it works is, bacteria likes sweetness, so they detect the oil swishing nearby and detach, so they can grab hold of it. When you spit it out, you are removing bad stuff from your mouth, and it's a lot more clean than brushing or flossing.
Stop Paying Your Dentist!
I used to have a joke when I'd visit the dentist for a cleaning. The technician (generally "she") would ask, "do you floss regularly?"
My response was "Certainly! Twice a year, every time I see you." :)
Now I've got a filling that leaped out and catches food, so I floss almost daily. That aside, though: I have needed a dentist a lot less since I started with this regimen. It's important to do it daily, which I am still working towards...
Hope this helps!
