How a Cosmetic Dentist Whitens Teeth

One of the most popular procedures cosmetic dentists offer is teeth whitening. Professional teeth whitening uses high-concentration bleaching agents not available in over-the-counter products. In-office whitening can lighten teeth by several shades in a single visit, typically using a hydrogen peroxide gel activated by a special light. Take-home whitening kits prescribed by the dentist use custom-made trays and professional-grade whitening gel for gradual whitening over 1-2 weeks. Professional whitening is more effective and longer-lasting than over-the-counter options. Results typically last 1-3 years with good oral hygiene.
