How to whiten teeth ?
Tooth whitening is a way to improve the colour of your teeth using hydrogen peroxide (a type of bleach).It is safe and effective if carried out by a dentist or under the supervision of a dentist.The change of teeth color comes as a result of external discoloration due to bad oral hygiene, excessive ingestion of coloring foods and drinks, the activity of chromatogen bacteria and fungi, etc., as well as of internal reasons the most common of wich is the excessive intake of fluoride and antibiotics in the early years of childhood. Tooth whitening does not remove any of the surface of the teeth or add anything to the teeth.
What happens during tooth whitening treatment?
Your dentist will apply a low but highly effective
concentration of hydrogen peroxide (bleach) to
your teeth using specially-made top and bottom
trays that fit snugly around your teeth. Each tray
is left in your mouth for a time.
n In addition, your dentist will show you how to fit the trays correctly at home, and give you some hydrogen peroxide gel (usually in tubes) to bring home to use in the trays. You will put the trays in your mouth at home daily for the time your dentist advises. Often this will be overnight.
