Professional bleaching or teeth whitening is carried out by your dentist. It can be external or internal. If you have external bleaching, the gel is placed on the outer surfaces of your teeth. Internal bleaching involves the bleaching product being put inside your tooth. External bleaching is more common, as internal bleaching can only be used if you’ve had root canal treatment, making access to the inside of your tooth easier.
