At-home vs at-the-dentist dental bleaching comparison is improper, because products available at each place are different in concentration, efficacy and results. The main reason why At-Home Teeth bleaching has gained popularity over In-Office Bleaching is the convenience with which the similar products are available, on the counter assuring efficacy and safety of these products.
Although the teeth bleaching is a procedure pertaining exclusively to dental practice, in matters of efficacy and safety, some manufacturers have introduced low concentration products in kit forms to claim the efficacy and safety thus keeping themselves away from FDA regulations.
With economical products available on the counter, many people prefer these products instead of paying higher price to the dentist for getting teeth bleached in-office.
Features of At-Home & In-office Bleaching:
Efficacy of Bleaching Ingredients:
At-home products are having low strength of bleaching ingredient, which is 10 % carbamide peroxide in potency which is equal to 3% hydrogen or 22% carbamide peroxide equal to about 6 % hydrogen peroxide.
