Cosmetic Dentistry
08/10/2011
Teeth whitening is a method of cosmetic dentistry designed to whiten, lighten or restore natural color to a tooth or teeth. Causes of discoloration often dictate how well the teeth take to different whitening processes, so consultation with a dentist is recommended.
The major types of teeth whitening include:
- Bondings
- Veneers
- In-office bleaching
- At-home bleaching
- Whitening toothpastes
Bondings and veneers are cosmetic dentistry applications that cover the existing tooth with a resin composite or porcelain covering to improve the appearance – or sometimes function – of the teeth. A dentist takes molds of the teeth for a dental lab to custom manufacture veneers. Resin bondings are created and applied in the dentist’s office with no need for outsourcing.
In-office bleaching involves a dentist-applied teeth whitening agent which is generally activated by a special light or laser to whiten the teeth enamel over the course of several visits.
At-home bleaching utilizes either dentist-obtained or over-the-counter teeth whitening products, usually containing peroxides administered with a dental tray worn over the teeth, that require a one to two week regimen to complete.
Whitening toothpastes go a step further than standard toothpastes in that they contain special chemical or polishing agents to aid in the removal of surface staining of the tooth enamel. They do not alter the deeper, intrinsic color of the tooth.
