How do I get white teeth?

Basically, you swish a spoonful of coconut oil around your mouth for up to 5 minutes, or as long as you can stand it, every morning before you brush your teeth or eat anything. If you want good results, you have to buy good quality oil. Organic, cold pressed and unrefined.
Generally, the longer you swish it around your mouth for, the better the results will be. There's no point in only doing it for 30 seconds. When you start off it will be difficult to keep it in your mouth for more than a minute. As long as you keep it in as long as possible and are actively moving the oil around your mouth, it will work.
Spit the oil into a bin. The spit should look cloudy and white - that means it pulled the toxins and bacteria from your mouth, gums and in between your teeth. Never spit it into the sink or toilet as it will harden and clog up the pipes.
If it's cold where you live and the oil is always hard in the container, you can either melt it in the microwave or just take the hard oil and keep it in your mouth until it turns soft. Whichever is easier for you.
