The first professional option is commonly referred to as “in-office” whitening. This procedure is performed in a dental office. An in-office whitening treatment may include the use of a whitening lamp or laser to enhance the effectiveness of the whitening gel by accelerating the peroxide.
During an office visit, your dental professional would apply the whitening gel and, depending on the system being used, will shine a light source directly onto the teeth. The entire office visit generally takes about 90 minutes with immediate results.
The biggest downside with this method seems to be the high amount of sensitivity that is often encountered and the variability in the end result.
