Teeth whitening can significantly brighten your smile by removing surface stains. The effectiveness of whitening treatments can depend on the type of staining and the natural color of your teeth. Professional whitening treatments often yield more dramatic results compared to over-the-counter products. Whitening procedures work best on yellowish stains rather than gray or brown discoloration. It’s important to have a dental checkup before starting whitening treatments to ensure your teeth and gums are healthy. Not all teeth respond equally to whitening; some individuals may experience better results than others. Teeth whitening may not be effective on crowns, veneers, or fillings, as these materials do not change color. Sensitivity can be a common side effect of teeth whitening, but it usually subsides after treatment. Maintaining good oral hygiene can help prolong the effects of teeth whitening. Whitening products should be used according to the manufacturer’s instructions to avoid potential damage to your teeth. Regular touch-ups might be necessary to maintain your desired level of whiteness. Lifestyle factors such as smoking and consuming staining foods or drinks can affect the longevity of whitening results.
