Hydrated silica can be somewhat effective for teeth whitening, but its use may cause certain damage to the tooth enamel. For teeth whitening, one option is professional cold light whitening, whose results typically become visible about two hours after treatment and usually last from one to three years, with prices generally ranging from 1,000 to 3,000 yuan. After cold light whitening, teeth may become sensitive, so it's advisable to avoid consuming excessively hot or cold foods in the short term.
