The best and surely most effective way to whiten your teeth in the privacy of your own home is to purchase a home whitening kit
. These kits give the dental surgery a run for its money, as they can be every bit as good as having the same process carried out in the dentist chair (and are significantly cheaper!) Just make sure your kit is approved by the FDA. Typically the kits consist of the whitening gel Carbamide Peroxide; strengths vary although it is recommended that any whitening gel over 16% should be avoided as it is thought to be not safe to be used at home. The kits come with a customisable mouth tray for both upper and lower teeth, a syringe applicator and the whitening gel itself. These kits enable you to achieve full teeth whitening of anything up to 11 shades whiter usually within 30 minutes and results can be seen from the first application, getting more intense each time you whiten. Results can last up to 2 years depending on your diet and lifestyle.
