subject: Why Teeth Whitening? [print this page] Professional teeth whitening is generally performed by a dentist, who will check that, your teeth and gums are healthy enough to undergo the procedure and if so, will apply a rubber shield or gel over the gums to protect them. Then a whitening gel/product is applied to the teeth, hydrogen peroxide or carbamide peroxide (which is more common nowadays) using a specially made mouth tray that is specially formed to fit the individuals mouth and teeth just the same as a gum shield. A blue laser light is normally used to quicken the process which can take up to an hour in some cases. As the peroxide is slowly broken down, oxygen gets into the enamel of the teeth and the tooth colour is then made lighter. It will not completely change the colour of a tooth and only natural teeth are suitable for this procedure, any dental restorative work, crowns, caps, veneers etc will not be lightened in this method and may have to be replaced or specially cleaned. It also may or may not require additional visits to the dental surgery, but you can prolong the whiteness at home using special whitening toothpastes and gels. Results overall can last for a couple of years depending on your diet but your dentist will be able to advise you on this.
