1 / Supersmile Intelligent Smile Care
A favorite at American Way, this system uses a proprietary form of calcium peroxide that dissolves stain-attracting proteins without dehydrating teeth or relying on harsh abrasives. New to the line are two delicious toothpaste flavors — icy mint and cinnamon ($21 each) — and the Advanced Sonic Pulse electric toothbrush ($99). www.supersmile.com

2 / Icing 30 Carats by Bling Dental
The name of this product isn’t the only thing that shines. Icing 30 Carats promises to make teeth several shades whiter in less than 90 minutes. Its contoured trays are filled with a gel that contains a high concentration of carbamide peroxide to make your teeth glow without increasing sensitivity. $169, www.icingteethwhitening.com

3 / 3D White
Crest and Oral-B have teamed up to offer affordable Whitestrips, mouth rinse, paste and brushes that work together for maximum brightening.

4 / Hollywood Smiles Teeth-Whitening System by Viatek
Relying on the same methods used by many dentists, Hollywood Smiles offers movie-star teeth for those on an extra’s budget. The kit uses a gel and a plasma lighting tool to make teeth four shades whiter in less than an hour. $40, www.viatekproducts.com
