Whitening can do wonders for how you feel about your smile, but regardless of if you choose a professional or over-the-counter method, you may not get the best possible results if your teeth are in need a deep cleaning.
Since bleach cannot penetrate through plaque and debris, your dentist may recommend undergoing a non-invasive, pre-whitening tooth-polishing procedure that uses pressurized air, water and baking soda to gently blast away stains and bacteria.
Much like a pressure wash for your teeth, this treatment requires no anesthesia and can be performed on its own or alongside professional cleanings, enabling your dentist to gauge your starting shade.
