How to whiten my teeth in 3-4 days?

Many OTC products: There are many teeth whitening strips available over the counter that promise results in a few days. Please check a consumer website for favorable reviews and read the ingredient labels to check for any potential allergies prior to your use.

Zoom: You can whiten your teeth several shades lighter with zoom whitening at a dentist office. The dentist will also make you custom made whitening trays and take home whitening gel with this procedure. At least that's how I do it. You can get a pretty nice result quickly with zoom. You will have some sensitivity, but the system comes with a gel that you can put in the trays to treat this.
