Teeth whitening is a cosmetic dental procedure aimed at lightening the color of the teeth, making them appear whiter and brighter. It is a popular non-invasive treatment used to enhance the aesthetics of a person's smile. This is a professional teeth whitening procedure performed by a dentist or dental hygienist. It involves applying a higher concentration of whitening agents, usually hydrogen peroxide or carbamide peroxide, directly to the teeth. To protect the gums and other soft tissues, a barrier is placed before the whitening agent is applied. The process may be accelerated using a special light or laser. In-office teeth whitening typically provides faster and more dramatic results compared to at-home methods. These are over-the-counter teeth whitening products that individuals can use at home. They often come in the form of whitening gels, strips, or trays. These products contain a lower concentration of whitening agents compared to professional treatments. The user applies the whitening agent to the teeth and leaves it on for a specified period, usually following the instructions provided with the product. At-home whitening may take longer to achieve noticeable results, but it can still be effective for mild to moderate teeth staining. Whitening toothpaste is a milder option for maintaining teeth brightness after professional or at-home whitening treatments. These toothpaste products contain mild abrasives and chemicals that help remove surface stains from the teeth over time.
