A Correct answer
Explanation

Bleaching is the dental procedure of applying hydrogen peroxide or carbamide peroxide solution to whiten discolored or stained teeth. The peroxide penetrates enamel and breaks down stains through oxidation. Scaling removes tartar, periodontitis is gum disease, and filling restores decayed tooth structure but doesn't change color.
