Teeth whitening can be done through professional in-office treatments, at-home kits, or using natural remedies. In-office treatments involve the use of high-concentration bleaching agents, usually hydrogen peroxide or carbamide peroxide, which are applied by a dental professional. They may also use light or laser technology to accelerate the whitening process. At-home kits typically contain lower-concentration bleaching agents and may include custom-made trays, whitening strips, or gel pens. Natural remedies often involve using ingredients like baking soda, hydrogen peroxide, or activated charcoal.
Teeth whitening is suitable for individuals with healthy teeth and gums, who want to improve the appearance of their smile. It is ideal for those with stained teeth caused by factors such as smoking, consumption of dark-colored foods and beverages, and age-related discoloration. However, it may not be effective for people with severe tooth discoloration or intrinsic stains caused by trauma, medication, or certain dental procedures.
