"if youre worried about oil and the adhesives, that should not be a problem or the dentist would have to tell you to eat a fat free diet, imho."
Trapper, this does not necessarily follow - with the oil pulling your teeth have a prolonged, continuous, direct exposure to the oil. The fats in food do not linger in your mouth. As anyone who has tried the oil cleansing method for their face knows, oil is brilliant for breaking down other oils and coaxing out the crud that gathers in our pores.
But I picked up some sunflower oil last night and gave it my first go this morning. I'll try it for a while and see how it goes. If my brackets start to loosen I'll just stop and try again in a few months when the braces come off.
Thanks to you and Molly for responding!
