Using coconut oil works no worse than factory rinses, and it’s safer.
In its pure form, coconut oil can be used for bleaching procedures 2-3 times a week, while enamel is not worth fearing. The easiest way: hold a spoonful of coconut oil in your mouth, then rinse your teeth thoroughly for 5 minutes.
You can also apply a little oil to a cotton pad and wipe the surface of the teeth. It is also advised to mix it with soda and brush your teeth with this mixture.
