Scientific Teeth‑Whitening Options Explained

Modern whitening products rely on peroxide compounds, such as hydrogen peroxide or carbamide peroxide. These agents break down the coloured particles within the enamel and dentin into smaller, less visible fragments. When used as directed, they can reduce stains from coffee, tea, tobacco and other chromogenic foods.

Over‑the‑counter whitening strips and gels are formulated to deliver a controlled peroxide concentration, offering gradual results with minimal risk. In‑office procedures performed by a dentist use higher concentrations under professional supervision, providing faster and more uniform whitening while protecting soft tissues.
