To give patients a radiant smile, teeth whitening procedures use hydrogen or carbamide peroxide to remove stains from tooth enamel. These teeth-whitening chemicals effectively eliminate surface stains caused by coffee, tea, tobacco, and age, thanks to the release of oxygen molecules during tooth penetration. Results from peroxide whitening, which may be done professionally or at home, show up fast. To avoid gum irritation or tooth sensitivity, however, you must closely follow the instructions for the greatest and safest outcomes.
