This dental code refers to the external bleaching of all the teeth in a single arch can be done either entirely in-office, or at home as part of a doctor-guided custom-tray application. Both teeth whitening techniques are best performed under your dentist's supervision to ensure the safest and most dependable results. There are a multitude of bleaching agents and systems in use for bleaching, and there are two main categories:
- In-Office Tooth Whitening: In this procedure, the teeth are carefully isolated from the lips and gums, and then a bleaching gel is applied. A special “curing” light is used in conjunction with the gel to activate the gel and accelerate the whitening process.
- At-Home Tooth Whitening: In this procedure, custom trays are made of your teeth during an initial visit. Once the trays are complete, you are provided with instructions for applying the bleaching agent at home.
