What is teeth whitening?
Teeth whitening is an increasingly popular dental procedure that involves removing teeth discolourations so as to achieve a brighter smile.
While there is a myriad of options available, some cheaper products are both ineffective and unsafe. Budget treatments that are inexpensively accessible online usually contain hydrogen peroxide and carbamide peroxide, both of which can be dangerous in illegally large amounts.
The allowed percentage of over-the-counter hydrogen peroxide is 0.1%. However, many products that are readily available contain an average of 3%.
