Teeth whitening is a simple procedure used to change natural tooth color and can be used to provide you with a dazzling smile.
Whether in the form of one-hour bleaching sessions in office, or home-use bleaching kits, whitening can be safely used without causing any damage to natural teeth.
What are Your Options
Three major teeth whitening options are available today. All three rely on varying concentrations of peroxide and varying application times.
Significant color change in a short period of time is the major benefit of in-office whitening. This protocol involves the carefully controlled use of a relatively high-concentration peroxide gel, applied to the teeth after the gums have been protected with a paint-on rubber dam. Generally, the peroxide remains on the teeth for several 15 to 20 minute intervals.
Professionally Dispensed Take-Home Kits
Take-home kits incorporate an easy-to-use lower-concentration peroxide gel that remains on the teeth for an hour or longer (sometimes overnight). The lower the peroxide percentage, the longer it may safely remain on the teeth. The gel is applied to the teeth using custom-made bleaching trays that resemble mouth guards.
Over-the-counter bleaching involves the use of a store-bought whitening kit, featuring a bleaching gel with a concentration lower than that of the professionally dispensed take-home whiteners. The gel is applied to the teeth via one-size-fits-all trays, strips or paint-on applicators. In many cases this may only whiten a few of the front teeth unlike custom trays that can whiten the entire smile.
