To whiten your teeth, swish around a standard 3% solution of hydrogen peroxide mixed with an equal amount of water in your mouth for 30 to 60 seconds once a day. Afterwards, rinse your mouth with water. Do this after brushing, or 30 minutes before brushing.
Make sure to not swallow any of the mixture.
There are also whitening treatments available in stores and pharmacies.
