What is whitening gel?
Basically, this is a special type of compound in gel form, that’s made to go on the teeth, for the purposes of actually stripping stains and whitening the teeth themselves. Most commonly this type of gel actually contains bleach, which is why you have to carefully monitor use, because bleach can be quite dangerous when ingested. What you’re also going to find is that whitening gel can include other types of compounds, but the general principle behind how the system is supposed to work is always the same.
