The color of human teeth is lightened by removing stains and discoloration through the cosmetic dental procedure known as teeth whitening New Orleans. It works through an oxidation process that uses bleaching chemicals such as carbamide peroxide or hydrogen peroxide to break down stain molecules and reveal a lighter color.
Discoloration occurs for several reasons, including extrinsic stains on the enamel from coffee, tea, and tobacco, or intrinsic yellowing as the outer enamel thins and exposes the naturally darker dentin underneath. These chromogens (stain molecules) are chemically broken down and bleached by whitening chemicals that penetrate the enamel.
General Procedures
- Professional In-Office Whitening: The quickest approach, performed by a dentist. It uses a concentrated peroxide gel and a specialized activation light or laser. It usually lasts about an hour and can whiten teeth by several shades in a single appointment.
- Take-Home Expert Kits: Your dentist creates custom-fitted mouth trays that you fill with professional-grade teeth whitening New Orleans gel. These are worn for a few hours each day or overnight for about one to four weeks.
- Over-the-Counter (OTC) Products: Items such as whitening strips, pens, and gels are readily available and contain lower peroxide concentrations. Although less expensive, they are less personalized and take longer than options offered by dentists. Whitening toothpastes do not include bleach; they mostly use mild abrasives to remove surface stains.
Teeth Stains: Types
- External stains: These are present on the enamel's surface. Poor oral hygiene, tobacco use, and dark-colored foods and beverages (such as coffee, tea, and red wine) are the main causes. Over-the-counter teeth whitening New Orleans treatments and regular professional cleaning typically work effectively to remove these surface stains.
- Intrinsic Stains: These develop deeper within the tooth structure, below the enamel layer. Trauma, excessive fluoride use as a child, or certain medications like tetracycline are frequently the causes. They are more difficult to remove since they are within the tooth and usually require professional cosmetic procedures like crowns or dental veneers.
- Stains related to Age: These develop naturally over time as a result of both intrinsic and extrinsic factors. The outer layer of enamel thins out as you get older, letting the naturally yellow dentin underneath show through.
