Teeth whitening is a popular cosmetic dental procedure aimed at enhancing the brightness of a person’s smile. Over time, teeth can become discolored due to various factors, including aging, consumption of stain-causing foods and beverages (like coffee, tea, and red wine), smoking, and certain medications. Teeth whitening treatments can be broadly categorized into two types: in-office procedures and at-home treatments.

In-office whitening involves the application of a strong bleaching agent by a dental professional. This method usually yields quick results, often lightening teeth by several shades in just one session. In contrast, at-home whitening kits typically include custom-fitted trays and a lower concentration of bleaching gel, allowing for gradual whitening over a week or two.
