1. Teeth whitening toothpaste
Some teeth whitening toothpaste uses gentle polishing agents to help remove stains on the surfaces of the teeth. Whilst some contain hydrogen peroxide that works by removing extrinsic and intrinsic stains other popular compounds used for whitening are O2 and carbamide.
Whiteness is created when an active ingredient, such as oxygen or carbamide penetrates the enamel on the teeth. The molecules in these products react with discolored sites causing them to break down into their component parts which then spread throughout other areas for faster whitening results. For example, the Optic White O2 Whitening Toothpaste uses millions of active oxygen bubbles to lighten the stains on the teeth, with a warming sensation that shows the formula is working.
2. LED teeth whitening
LED teeth whitening kits to use the effectiveness of blue light technology to activate hydrogen peroxide gel. You can achieve professional-level whitening with efforts worth a few minutes a day (this may vary across different LED teeth whitening products). These devices are generally enamel-safe, and rechargeable via a handy USB cable.
Colgate LED whitening products use Indigo light which delivers superior results than the blue one.
3. Teeth whitening pens
A teeth whitening pen uses a hydrogen peroxide-based serum or gel to improve the shade of the teeth. The process is simple and easy, and you can get rid of stains in hard-to-reach places with these fantastic new products. Just paint the whitening gel/film onto each tooth and let it do its thing over the specified amount of time.
